The Outcome of Bicolumnar Acetabular Fracture Treated by Single Anterior Ilioinguinal Approach

Background: Acetabular fracture therapy, being complicated, is generally treated by non-operative methods due to a lack of surgeons’ expertise in pelvis surgery. The surgical exposure and reduction of acetabular fractures may become more direct and practical with the altered technique since it is closer to the acetabular quadrilateral plate. This study aimed to determine the efficacy of a single anterior illio-inguinal approach for the management of a Bi-columnar acetabulum fracture. Methods: Sixty patients, fulfilling the selection criteria were selected for descriptive case series from Orthopedic Surgery Department at Lahore General Hospital, from 02-12-2020 to 02-06-2021. After informed consent, surgery was performed on all patients under general anesthesia. Patients were followed-up and evaluated for efficacy in OPD after 12 weeks of surgery with a Harris hip score. All demographic and other information was recorded on a Proforma. SPSS 22 was used to assess data. Post-stratification, efficacy was compared by using chi-square, p-value ≤0.05 was considered significant. Results: Out of 60 patients, 45(75 %) were male, whereas 15(25%) were female (Mean age 52.71±10.50yrs). The Mean of duration fracture (in days) and Harris score are 11.03±5.29 and 2.83±0.45 respectively. The efficacy concerning lateral side was 60% for left side and 26.7% for right side. Efficacy was higher in less than 10 days old fractures at 55.0% while after 10 days it was 31.7%. We found that the percentage of efficacy was 86.7%. Conclusion: The current study concluded that the anterior illio-inguinal approach is highly effective (p=0.001) in the management of acetabular fractures.

Efficacy and safety of pararectus approach for the treatment of acetabular fractures: A systematic review and meta-analysis

BackgroundThe pararectus (PR) approach combines the advantages of the second window of the ilioinguinal approach and the medial view of the modified Stoppa approach. However, it is unclear whether the PR approach is more effective or safer than the other approaches, as few clinical studies have compared the PR approach with the other approaches. The aim of this study was to provide a systematic review and meta-analysis comparing the PR approach with the other approaches for the treatment of acetabular fractures and to answer the following question: Are the results of the PR approach superior to those of the other approaches in terms of reduction quality, operative time, operative blood loss, complications, and clinical outcomes for treatment of acetabular fractures? Patients and methodsA systematic literature review was conducted using relevant original studies from various databases. Pooling of data was performed using RevMan software (version 5.3, Cochrane Collaboration, Oxford, UK). A p-value<0.05 was considered to be significant. We calculated the mean differences for continuous data and odds ratio for dichotomous data with 95% confidence intervals for each outcome. Statistical heterogeneity was assessed based on I2 using the standard χ2 test. ResultsFive studies were included in this meta-analysis. The findings demonstrated that operative blood loss was significantly lower in the PR approach than in the other approaches (p=0.04). There was no significant difference in the rate of anatomical reduction, the operative time, the rate of complications, and the rate of excellent or good clinical score between the PR approach and the other approaches. DiscussionThe PR approach provided lower operative blood loss, although there was no significant difference in reduction quality, operative time, complications, and excellent or good clinical score between the PR approach and the other approaches. Level of evidenceIII.

The use of suprapectineal plate in acetabular fractures via ilioinguinal approach with Stoppa window.

The aim of the study was to investigate the clinical results of open reduction and internal fixation using a suprapectineal buttress plate for specific acetabular fractures. We conducted a retrospective study involving thirty-three patients with specific acetabular fractures in an academic level 2 trauma center. We performed the ilioinguinal approach with Stoppa window for buttress plating of the quadrilateral surface. Clinical examination, radiographs and computed tomography were done using criteria described by Matta. Functional outcome was evaluated by visual analog scale (VAS), WOMAC, Harris Hip score modified, Hip disability and Osteoarthritis Outcome Score (HOOS) and modified Merle d'Aubignè scoring system. Average follow-up was 40.4 months with a minimum of 24 months. Mean age was 59.09 years. The 82% of patients were treated with a suprapectineal plate using ilioinguinal approach with Stoppa window. The 18% of patients required a Kocher-Langenbeck approach in order to get anatomic reduction of posterior wall or column. The 91% of patients were satisfied of their condition during activity of day living and only a small cohort reported walking aids. The worst clinical results were obtained in patients characterized by highest step displacement. Deep infection of surgical wound was observed in 6% of patients. In 3% of patients, one vascular injury occurred during surgery. Internal fixation using ilioinguinal approach with Stoppa window and a suprapectineal plate to buttress the quadrilateral plate should be considered a viable treatment of some acetabular fractures. Patients can expect a good functional outcome with a low complication rate.

Surgical Approaches for Acetabulum Fracture Treatment: Analytic Review

Background. The use of classical and modified surgical approaches to acetabulum is accompanied by serious intra- and postoperative complications associated with tissues, vessels, nerves, and lymphatic structures injury. The choice of approach to acetabulum affects the surgical time and the blood loss volume.&#x0D; The aim of the review was to compare the surgical time and blood loss volume using different surgical approaches to the acetabulum based on the relevant literature analysis.&#x0D; Methods. The search was carried out in PubMed/MEDLINE and Scopus databases from 1964 to 2022. When conducting a search for the phrases acetabular fractures, surgical approach to the acetabulum, 4368 articles were found. As a result of the selection, 12 publications containing the most complete information on the studied indicators were included in the quantitative analysis.&#x0D; Results. The data of surgical treatment of 540 patients with acetabulum fractures were analyzed. The average age of the patients was 45.211.6 years. Among the causes of pelvic and acetabulum fractures, road accident (70.4%) and falls from height (21.3%) largely prevailed. The blood loss depended on the use of specific approaches or their combination, and the surgical time. The shortest surgical time (101.027.0 min.) was required using pararectal approach, the longest (26456.4 min.) with the use of ilio-inguinal approach. The largest volume of blood loss was observed with Pfannenstiel approach 1057.1377.9 ml. No statistically significant differences were found when comparing the Kocher-Langenbeck (793328 ml), ilio-inguinal (82864 ml) and pararectal (798322 ml) approach. Performing the Kocher-Langenbeck approach in the patients lateral position reduces the surgical time by 16.8% and reduces blood loss by 12.4% compared to the patients prone position.&#x0D; Conclusion. Comparative clinical studies are required to determine the safest surgical approaches to the acetabulum, depending on the type of fracture, the mechanism of injury and the age of the patient.

Novel Covert-Inferior Pelvic Approach with a Subpubic Plate for Anterior Pelvic Ring Fractures: Preliminary Results.

Anterior pelvic ring injuries can be treated via Pfannenstiel, modified Stoppa, or ilioinguinal approaches, but these require exposing the abdominal soft tissues and may damage pelvic organs. The scar on the abdominal wall is also unacceptable for some patients. The minimally invasive anterior pelvic ring internal fixator (INFIX) is not ideal for thin patients with easily irritated skin, and it is associated with complications such as femoral nerve palsy, vascular occlusion, and lateral femoral cutaneous nerve injury. In this study, we designed a new external pelvic approach for the treatment of an anterior pelvic ring fracture. We retrospectively reviewed 28 patients with 36 pubic ramus fractures that had been treated via the covert-inferior pelvic approach. All patients underwent a surgical procedure between August 2019 and January 2021. According to the Nakatani classification, there were 6 cases of type-I fracture, 25 cases of type-II fracture, and 5 cases of type-III fracture. Operative time, blood loss, and postoperative radiographic and computed tomographic (CT) findings were recorded. Patients were followed for fracture healing time, functional status, esthetic satisfaction, and complications. A total of 27 patients had follow-up for at least 12 months (range, 12 to 29 months). Postoperative radiographs and CT scans showed well-positioned plates and screws. The mean preoperative time was 9.4 ± 3.8 days, the mean operative time was 61.3 ± 22.67 minutes, the mean intraoperative blood loss was 63.6 ± 42.62 mL, the mean fracture healing time was 4.1 ± 1.6 months, and the mean Majeed score was 89.74 ± 8.07. There were no complications of nonunion, internal fixation failure, vascular injury, nerve palsy, or hernia. All of the patients were esthetically satisfied with the scar. The covert-inferior pelvic approach combined with a subpubic plate effectively fixed Nakatani type-I, II, and III fractures. The advantages of this method include rapid recovery after the surgical procedure, safety, simplicity, a short learning curve, no damage to abdominal soft tissue, no effect on pubic symphysis micromotion, and esthetic benefits. It may be another option for anterior pelvic ring fractures and can supplement other approaches. Therapeutic Level III .

Simultaneous reduction and fixation using an anatomical suprapectineal quadrilateral surface plate through modified Stoppa approach in superomedially displaced acetabular fractures

Treatment of superomedially displaced acetabular fractures including a quadrilateral surface (QLS) is challenging. We present a surgical technique using an anatomical suprapectineal QLS plate through the modified Stoppa approach and report the availability of this plate to treat this fracture type along with the surgical outcomes. Sixteen consecutive patients (14 men and 2 women) who underwent surgical treatment using an anatomical suprapectineal QLS plate through a modified Stoppa approach for superomedially displaced acetabular fractures between June 2018 and June 2020, were enrolled retrospectively. These fractures included 11 both-column fractures and 5 anterior-column and posterior hemitransverse fractures, which were confirmed on preoperative 3-dimensional computed tomography. Surgical outcomes were clinically assessed using the Postel Merle d’Aubigné (PMA) score and visual analog scale (VAS) score at the final follow-up, and radiological evaluations were performed immediately after the operation and at the final follow-up. For comparative analysis, 23 patients who underwent internal fixation with the conventional reconstruction plate through modified ilioinguinal approach between February 2010 and May 2018, were selected. This control group was composed of 18 both-column fractures and 5 anterior-column and posterior hemitransverse fractures. The follow-up period was at least 1 year in all patients. The mean operation time and blood loss was 109 min, and 853 ml, respectively, whereas 236 min, and 1843 ml in control group. Anatomical reduction was achieved in 14 (87.5%) patients, while imperfect reduction was achieved in the remaining 2 patients. At the final follow-up, radiographic grades were excellent, fair, and poor in 14 patients (87.5%), one, and one, respectively. The mean PMA score was 16.1 (range 13–18) and the mean VAS score was 1.0 (range 0–3). No secondary reduction loss or implant loosening was observed. However, 2 patients underwent conversion to total hip arthroplasty (THA) due to post-traumatic arthritis and subsequent joint pain. No other complications were observed. In the comparative analysis, radiological outcome showed a significant relationship with the conversion to THA (p = 0.013). Shorter operation time and less blood loss were significantly observed in the QLS plate fixation group through the modified Stoppa approach compared with the conventional reconstruction plate fixation group through modified ilioinguinal approach (p < 0.001, respectively). Simultaneous reduction and fixation using an anatomical suprapectineal QLS plate through the modified Stoppa approach may be a viable technique in superomedially displaced acetabular fractures along with shorter operation time and less blood loss.

Clinical Outcomes of the Modified Stoppa Combined with Iliac Fossa Approach for Complex Acetabular Fractures: A Medium- and Long-term Retrospective Study.

ObjectiveThe modified Stoppa combined with iliac fossa approach has gained increasing popularity. Although early clinical outcomes have been satisfactory, extensive long‐term clinical outcomes are relatively scarce. The purpose of this study was to evaluate the medium‐ and long‐term outcomes of this approach for complex acetabular fractures.MethodsThis was a retrospective study involving 57 patients with complex acetabular fractures from January 2009 to January 2016. All fractures were treated with the modified Stoppa combined with iliac fossa approach. Follow‐up was at least 5 years. Primary outcome measures, including quality of reduction and clinical outcomes, were recorded by an independent observer. Secondary outcome measures included time to surgery, surgical time, intraoperative blood loss, and perioperative complications.ResultsFifty‐seven patients (range, 18–80 years) included 46 males and 11 females. There were 32 cases on the left side and 25 cases on the right side. The most common associated injury was pulmonary contusion. According to the Judet–Letournel classification, there were 27 both‐column fractures, 16 anterior column with posterior hemitransverse fractures and 14 T‐type fractures. The average time from injury to surgery was 7.3 days. The average intraoperative blood loss and transfusion were 750.9 ml and 564.3 ml, respectively. All fractures healed within 6 months after surgery. The average follow‐up time was 7.7 years, and there was no loss of follow‐up. The quality of reduction was graded as anatomical in 23 cases (40.4%), imperfect in 22 cases (38.6%), and poor in 12 cases (21.0%). According to grading system of Merle d’ Aubigne and Postel, clinical outcomes at 1 year follow‐up were excellent in 17 cases (29.8%), good in 25 cases (43.9%), fair in four cases (7.0%), and poor in 11 cases (19.3%). The excellent and good rate was 73.7% and the difference was not statistically significant compared with the clinical outcomes at the last follow‐up. Intraoperative complications included four cases of obturator nerve injury and two cases of vascular injury. Postoperative complications included one case of wound delayed healing, two cases of deep vein thrombosis, two cases of avascular necrosis of femoral head, three cases of heterotopic ossification and five cases of post‐traumatic arthritis. Only one of these patients underwent reoperation for femoral head necrosis.ConclusionsThe modified Stoppa combined with iliac fossa approach can achieve satisfactory reduction quality and hip function. It might be a valuable alternative to the ilioinguinal approach for the surgical management of acetabular fractures.

Application of modified Gibson combined with modified ilioinguinal approach in treatment of Enneking Ⅱ+ Ⅲ pelvic malignant tumors with three-dimensional printed hemipelvic prosthesis replacement

To explore the surgical skills of modified Gibson combined with modified ilioinguinal (MGMII) approach in the treatment of Enneking Ⅱ+Ⅲ pelvic malignant tumors in the three-dimensional (3D) printed customized integrated hemipelvic prosthesis, and to evaluate the convenience and accuracy of the surgical approach and the short-term effectiveness. Between January 2017 and March 2019, 7 patients with Enneking Ⅱ+Ⅲ pelvic malignant tumors were treated with tumor resection and 3D printed hemipelvic prosthesis replacement via MGMII approach. There were 6 males and 1 female. The age ranged from 23 to 68 years, with an average of 43.7 years. There was 1 chondrosarcoma, 1 Ewing's sarcoma, 1 osteosarcoma, 1 malignant Schwannoma, 2 metastatic renal clear cell carcinoma, and 1 metastatic hepatocellular carcinoma. The Enneking stage of 4 cases of primary malignant tumor was stage ⅡB. The disease duration was 6-12 months, with an average of 9.5 months. The preoperative Harris hip score (HHS) was 82.1±1.4 and the Musculoskeletal Tumor Society (MSTS) score was 21.4±1.1. The tumor size by imaging examination was 5.1-9.1 cm, with an average of 6.9 cm. The operation time, intraoperative blood loss, postoperative blood transfusion volume, and postoperative complications were recorded. Postoperative pathological examination confirmed tumor residue according to R classification criteria. The lower limb length, acetabular height, acetabular eccentricity, abduction angle, and anteversion angle were measured and the bone integration was observed by imaging review. Bilateral abductor muscle strengths were measured, and joint function was evaluated by MSTS score and HHS score. All operations were successfully completed. The operation time was 210-360 minutes (mean, 280.0 minutes); the intraoperative blood loss was 1 300-2 500 mL (mean, 1 785.7 mL); the postoperative blood transfusion volume was 0-11 U (mean, 6.1 U). Postoperative pathological examination confirmed R0 resection assisted by osteotomy guide plate. All incisions healed by first intention. All patients were followed up 30-48 months (mean, 41.3 months). At last follow-up, the imaging review showed the good osseointegration in all 7 cases. There was no significant difference in the lower limb length, acetabular height, acetabular eccentricity, abduction angle, and anteversion angle between the affected side and the healthy side ( P>0.05), all of which met the requirements of anatomical reconstruction. At 3 months after operation, the ratios of muscle strength between the affected side and the healthy side was 68.29%±7.41% at 3 months and 89.86%±2.79% at 12 months, showing a significant difference between the two time points ( t=8.242, P=0.000). At last follow-up, the MSTS score and HHS score were 27.3±0.8 and 96.6±1.4, respectively, which significantly improved when compared with those before operation ( P<0.05). None of the patients had assisted walking at last follow-up. There was no recurrence, death, or complications such as deep infection, dislocation of the prosthesis, or fracture of the prosthesis or screw. MGMII approach can expose the posterior column of the acetabulum, especially the ischial tubercle, which is helpful to avoid tumor rupture during tumor resection and preserve the muscle functions such as gluteus medius and iliac muscle while ensuring the resection scope.

Combined and Modified Gibson and Ilioinguinal Approaches in Type II + III Internal Hemipelvectomy for Periacetabular Tumors.

BackgroundThe routine iliofemoral approach and its modifications in type II+III resection require extensive skin incision and massive periacetabular muscle detachment, leading to prolonged hospital stay, increased complication incidence, and impaired lower limb function. Under the management of an enhanced recovery after surgery (ERAS) protocol, a combined and modified Gibson and ilioinguinal (MGMII) approach was used to avoid unnecessary soft tissue trauma during tumor resection and therefore advantageous to patients’ return to normal life.MethodsTwenty-five patients with type II + III (including type II) periacetabular tumors who underwent reconstruction with 3D printed customized endoprostheses at our center between January 2017 and March 2019 were included in this study. There were 13 cases using MGMII approach and 12 cases using iliofemoral approach. The operation duration and blood loss were assessed by chart review. The surgical margin was evaluated by the histopathological studies. The reconstruction accuracy, the abductor muscle strength, the 1993 version of the Musculoskeletal Tumor Society (MSTS-93), the Harris Hip scores (HHS), and the limp score were evaluated. Complications were recorded after reviewing the patients’ records.ResultsThe operative duration and blood loss in MGMII group were shorter than those in the iliofemoral group, but the postoperative hemoglobin was slightly higher than that in the iliofemoral group. The MGMII group had stronger postoperative hip abductors, better functional restoration, and relatively fewer patients with higher limp scores. No complication was observed in the MGMII group. In the iliofemoral group, three patients encountered wound healing delay, and one patient suffered deep infection.ConclusionsThe MGMII approach can better expose the posterior column of the acetabulum, especially the ischial tuberosity, which is beneficial for avoiding tumor rupture during resection. The MGMII approach also helps to preserve residual muscle function, such as the origin of the gluteus medius, while ensuring the extent of resection.

Evaluation of Socio-Demographic and Clinical Parameters after Open Reduction and Internal Fixation of Acetabulum Fractures

Background: The present study was done to evaluate the sociodemographic and clinical parameters after open reduction and internal fixation of acetabulum fractures. Material and methods: The present study was done in 44 patients of fracture acetabulum managed by open reduction internal fixation in the Department of Orthopaedic surgery, Indira Gandhi Medical College, Shimla. Results: There were 16 prospective (36.4%) and 28 retrospective (63.6%) cases. The mean age was 45.07 years with maximum number of 39 (88%) patients in the age group of 21- 60 years. Majority (77.3%) of the patients was males and 22.8 % were females. Forty three (97.7%) patients belonged to rural area and remaining 1(2.3%) patient belonged to urban area. Road traffic accident was the mode of injury in 63.6% patients followed by fall from height in 36.4%. Eighteen (41%) patients had posterior wall fracture followed by posterior wall with posterior column fracture was seen in 12 (27%). Average time interval between injury and surgery was 15 days (range 3-55 days). Thirty six percent of the patients were operated between 8-14 days and 34 % of patients between 0-7days. Thirty (68%) patients were operated by Kocher-Langenbeck approach in lateral position followed by 7 (15%) patients with ilioinguinal approach in supine position. Autogenous Bone graft was used in 31.7% of patients. Mean duration of hospital stay was 24 days (range 7-35 days). Conclusion: Study concluded that most of the patients were in the age group of 21- 60 years, males, belonged to rural area, injured due to Road traffic accidents, had posterior wall, operated within 15 days and were operated by Kocher-Langenbeck approach in lateral position.

The Impact of Surgical Approaches for Isolated Acetabulum Fracture on Sexual Functions: A Prospective Study.

To investigate the effects of surgical modalities for isolated acetabular fractures on the sexual functions of patients and their partners. Prospective. Level I trauma centre. Sixty-five patients who had undergone open reduction and internal fixation because of isolated acetabular fractures who were sexually active before, together with their partners. Patients operated on for isolated acetabular fractures were divided into 3 groups according to surgical approaches: the Kocher-Langenbeck approach (n = 36), ilioinguinal approach (n = 16), and modified Stoppa approach (n = 13). Sexual functions of patients and their partners were evaluated with the 5-item version of the International Index of Erectile Function score and Female Sexual Function Index score preoperatively and at the postoperative first year after the rehabilitation period. The mean age of the patients was 41.8 ± 13.0 (18-69) years. In male patients, the mean 5-item version of the International Index of Erectile Function score had changed from 24.3 to 20.0 at the postoperative first year and the decrease in sexual function scores was less with the Kocher-Langenbeck approach. In female patients, the Female Sexual Function Index scores had decreased statistically significantly from 24.9 to 18.3 at the postoperative first year, but there was no statistically significant difference between surgical groups. Both male and female patients' partners' sexual function scores were also decreased at the postoperative first year. As a result of our study, it was observed that the posterior approach is more advantageous than anterior approaches in preserving the sexual functions of male patients in acetabular fracture surgery. However, the surgical approach did not affect the sexual functions of female patients. Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Modified Stoppa Approach For Concomitant Anterior And Posterior Pelvic Ring Fracture: A case report

BACKGROUNDModified Stoppa approach was performed to access the site of anterior column fracture instead of the Ilioinguinal approach to reduce morbidity.CASE SUMMARYA 24-year-old female suffered a serious traffic accident when she was riding a motor cycle collided with a car from the front and fell off when dodged a hole on the road. Then, the patient was beneath a moving car after falling. Several hours after accident at the hospital, she diagnosed as closed pelvic fracture of right superior inferior pubic rami and right sacroiliac joint disruption, closed fracture of right shaft femur. After improvement the condition in the ward, open reduction and internal fixation for the femoral fracture and for the pelvis fracture were performed using a modified stoppa approach to access the fracture site.CONCLUSION Treatment using the modified Stoppa approach was suitable for anterior column fracture, in which pelvic fractures were sufficiently exposed, the fracture was conveniently reduced, less complications occurred, and curative effect was satisfactory.

Clinical efficacy and its influencing factors of surgical treatment for T-shaped associated with posterior wall acetabular fractures\xa0using combined surgical approaches

BackgroundThe objective of this study was to evaluate the outcomes of surgical treatment for T-shaped associated with posterior wall acetabular fractures using combined surgical approaches and its influencing factors.MethodsBetween January 2009 and June 2018, a total of 21 patients with T-shaped acetabular fractures involving posterior wall were treated with combined approaches. The combined approaches were a combination of the Kocher-Langenbeck (KL) approach and the anterior approach (Stoppa or Ilioinguinal). The acetabular fractures in this study were divided into two groups respectively according to surgical approach and surgical timing: KL + Ilioinguinal (IL) approaches and KL + Stoppa approaches, early surgery and late surgery.Results13 cases were treated within 14 days of injury. 15 cases were treated using the KL + Stoppa approaches and remaining 6 cases were treated using the KL + IL approaches. Anatomical and imperfect reduction were achieved in 12 cases (57.1%) with excellent to good clinical outcome in 42.9% of cases. Early surgery had a statistically significant improvement over late surgery in terms of quality of reduction and clinical outcomes. In the early surgery, the incidence of preoperative chest and abdomen injuries and postoperative deep vein thrombosis was significantly lower than that of the late surgery. There was no statistical difference between the KL + IL approaches and KL + Stoppa approaches in the demographics, preoperative associated injuries, quality of reduction, clinical outcomes and postoperative complications.ConclusionsThe results of this study indicate that T-shaped associated with posterior wall acetabular fractures are difficult to treat surgically. Early surgery can improve the quality of fracture reduction, promote the recovery of hip function, and decrease the incidence of postoperative deep vein thrombosis. The main factor that affects surgical timing is the presence of preoperative chest and abdominal injuries. Compared with the KL + IL approaches, the KL combined with Stoppa approach can not significantly improve the clinical outcomes of such acetabular fractures.

Comparaison des voies ilio-inguinale et Stoppa modifiée dans le traitement des fractures de l’acetabulum : mise à jour systématique de la littérature et méta-analyse

BackgroundThe modified Stoppa (MS) approach is an alternative to the ilioinguinal (IL) approach and three meta-analyses comparing these two approaches for the treatment of acetabular fractures were published previously. The aim of this study was to provide an updated systematic review and meta-analysis comparing the MS approach with the IL approach for the treatment of acetabular fractures and to answer the following question: Are the results of the MS approach superior to those of the IL approach in terms of reduction quality, operative time, operative blood loss, complications, and clinical outcomes for treatment of acetabular fractures? Patients and MethodsAn updated systematic literature review was conducted using relevant original studies from various databases (PubMed, Web of Science and the Cochrane Library). Pooling of data was performed using RevMan software (version 5,3, Cochrane Collaboration, Oxford, UK). A p-value of<0.05 was considered to be significant. We calculated the mean differences (MDs) for continuous data and odds ratio (OR) for dichotomous data with 95 % confidence intervals (CIs) for each outcome. Statistical heterogeneity was assessed based on I2 using the standard χ2 test. When I2>50 %, significant heterogeneity was assumed and a random-effects model was applied for the meta-analysis. A fixed-effects model was applied in the absence of significant heterogeneity. ResultsSix studies were included in this meta-analysis. The findings demonstrated that the rate of anatomical reduction was significantly higher in the MS approach than in the IL approach (I2=0 %, OR=1.75, 95 % CI: 1.13–2.69, p=0.01), the operative time was significantly shorter in the MS approach than in the IL approach (I2=88 %, MD=−63.60, 95 % CI: −93.01–(−34.20), p<0.0001) and operative blood loss was significantly lower in the MS approach than in the IL approach (I2=75 %, MD=−350.51, 95 % CI: −523.45–(−177.58), p<0.0001). There was no significant difference in the rate of nerve injury (I2=0 %, OR=0.47, 95 % CI: 0.16–1.39, p=0.17), the rate of vascular injury (I2=0 %, OR=0.51, 95 % CI: 0.17–1.49, p=0.22), the rate of infection (I2=0 %, OR=0.53, 95 % CI: 0.25–1.12, p=0.10), the rate of heterotopic ossification (I2=45 %, OR=0.63, 95 % CI: 0.22–1.85, p=0.40), and the rate of excellent or good clinical score (I2=21 %, OR=1.15, 95 % CI: 0.56–2.38, p=0.70) between the two approaches. DiscussionThe MS approach provided better reduction quality, shorter operative time, lower operative blood loss, although there were no significant differences in the rate of complications, and excellent or good clinical score between the two approaches.

Ilioinguinal versus modified Stoppa approach for open reduction and internal fixation of displaced acetabular fractures: a systematic review and meta-analysis of 717 patients across ten studies.

Acetabulum fracture is one of the most challenging fractures to manage and operate for orthopaedic surgeons; anatomical reduction of fractures and reconstruction of the joint is of utmost importance. These factors in turn are dependent on the appropriate surgical approach used to improve the clinical outcomes and reduce associated complications. Hence, this meta-analysis aims to compare the outcomes of ilioinguinal versus modified Stoppa approach for open reduction and internal fixation (ORIF) of displaced acetabular fractures. Medline (PubMed), Embase, Scopus, and Cochrane Library databases were searched from their inception to 10th of June 2021 for both randomized clinical trials (RCTs) and or non-randomized studies comparing the outcomes of ilioinguinal approach and modified Stoppa approach for the ORIF of acetabular fractures. The estimates of treatment effects were described by mean difference (MD) for continuous variables and odds ratio (OR) for dichotomous variables with corresponding 95% confidence (95% CI) intervals. The risk of bias was assessed by MINORS tool for the non-randomized, and the Cochrane Collaboration's risk of bias tool for RCTs. A total of ten studies (717 patients), three RCTs and seven retrospective studies, were included. Modified Stoppa approach showed shorter mean duration of surgery (MD 47.13, 95% CI: 27.30-66.96), lesser number of overall complications (OR 2.14, 95% CI: 1.46-3.13), less intraoperative blood loss (MD 259.65, 95% CI: 152.66-366.64), and lower rates of infection (OR 2.17, 95% CI: 1.14-4.15). However, ilioinguinal approach showed a better quality of fracture reduction (OR 0.59, 95% CI: 0.42-0.82). Results were equivocal in terms of vascular injuries (OR 1.88 (95% CI: 0.86-4.09), nerve injuries (OR 1.77, 95% CI: 0.99-3.17), heterotopic ossification (OR1.74, 95% CI: 0.63-4.82), and clinical outcome (OR 0.81, 95% CI: 0.45-1.47) between the two groups. Modified Stoppa approach carries a lesser duration of surgery, lesser intraoperative blood loss, fewer overall complications, and lesser postoperative infection rates compared to ilioinguinal approach. Although a better anatomical reduction is achieved by ilioinguinal approach, however, this does not translate into better clinic functional outcomes which remain comparable between the two approaches. So overall, modified Stoppa approach seems a better alternative for managing these fractures.

Comparison between ilioinguinal approach and modified Stoppa approach for the treatment of acetabular fractures: An updated systematic review and meta-analysis

BackgroundThe modified Stoppa (MS) approach is an alternative to the ilioinguinal (IL) approach and three meta-analyses comparing these two approaches for the treatment of acetabular fractures were published previously. The aim of this study was to provide an updated systematic review and meta-analysis comparing the MS approach with the IL approach for the treatment of acetabular fractures and to answer the following question: are the results of the MS approach superior to those of the IL approach in terms of reduction quality, operative time, operative blood loss, complications, and clinical outcomes for treatment of acetabular fractures? Patients and methodsAn updated systematic literature review was conducted using relevant original studies from various databases (PubMed, Web of Science and the Cochrane Library). Pooling of data was performed using RevMan software (version 5.3, Cochrane Collaboration, Oxford, UK). A p-value of<0.05 was considered to be significant. We calculated the mean differences (MDs) for continuous data and odds ratio (OR) for dichotomous data with 95% confidence intervals (CIs) for each outcome. Statistical heterogeneity was assessed based on I2 using the standard Chi2 test. When I2>50%, significant heterogeneity was assumed and a random-effects model was applied for the meta-analysis. A fixed-effects model was applied in the absence of significant heterogeneity. ResultsSix studies were included in this meta-analysis. The findings demonstrated that the rate of anatomical reduction was significantly higher in the MS approach than in the IL approach (I2=0%, OR=1.75, 95% CI: 1.13–2.69, p=0.01), the operative time was significantly shorter in the MS approach than in the IL approach (I2=88%, MD=−63.60, 95% CI: −93.01 – (−34.20), p<0.0001) and operative blood loss was significantly lower in the MS approach than in the IL approach (I2=75%, MD=−350.51, 95% CI: −523.45 – (−177.58), p<0.0001). There was no significant difference in the rate of nerve injury (I2=0%, OR=0.47, 95% CI: 0.16–1.39, p=0.17), the rate of vascular injury (I2=0%, OR=0.51, 95% CI: 0.17–1.49, p=0.22), the rate of infection (I2=0%, OR=0.53, 95% CI: 0.25–1.12, p=0.10), the rate of heterotopic ossification (I2=45%, OR=0.63, 95% CI: 0.22–1.85, p=0.40), and the rate of excellent or good clinical score (I2=21%, OR=1.15, 95% CI: 0.56–2.38, p=0.70) between the two approaches. DiscussionThe MS approach provided better reduction quality, shorter operative time, lower operative blood loss, although there were no significant differences in the rate of complications, and excellent or good clinical score between the two approaches.

A novel technique for stabilising sacroiliac joint dislocation using spinal instrumentation: technical notes and clinical outcomes

PurposeCurrently, sacroiliac joint dislocations, including crescent fracture–dislocations, are treated using several techniques that have certain issues. We present the technical details and clinical outcomes of a new technique, anterior sacroiliac stabilisation (ASIS), performed using spinal instrumentation.MethodsASIS is performed with the patient in a supine position via the ilioinguinal approach. The displacements are reduced and fixed by inserting cancellous screws from the sacral ala and iliac brim; the screw heads are bridged using a rod and locked. We performed a retrospective review of patients with iliosacral disruption who underwent ASIS between May 2012 and December 2020 at two medical facilities. The patients were assessed for age, sex, injury type, associated injuries, complications, functional outcome by evaluating the Majeed pelvic score after excluding the sexual intercourse score and fracture union.ResultsWe enrolled 11 patients (median age: 63 years). The median operative time was 195 min, median blood loss was 570 g, and eight patients (72.3%) required blood transfusion. The sacral and iliac screws had a diameter of 6.0–8.0 mm and 6.2–8.0 mm, and a length of 50–70 mm and 40–80 mm, respectively. Bone union was achieved with no marked loss of reduction in the median follow-up period of 12 months in all cases. The median Majeed score at the final follow-up was 85/96.ConclusionASIS is a rigid internal fixation method that provides angular stability. Despite invasiveness issues compared to iliosacral screw fixation, this method is easy to confirm and achieves precise reduction.

Anterior intrapelvic approach and suprapectineal quadrilateral surface plate for acetabular fractures with anterior involvement: a retrospective study of 34 patients

BackgroundThe purpose of the study is to evaluate the use of the suprapectineal quadrilateral surface (QLS) plates associated with the anterior intrapelvic approach (AIP) to the acetabulum in the surgical treatment of acetabular fractures with anterior involvement.MethodsWe did a retrospective study of patients surgically treated with QLS plates and AIP for acetabular fractures with the involvement of the anterior column, between February 2018 and February 2020, in our Hospital. The following data were recorded: mechanism of injury, the pattern of fracture, presence of other associated injuries, the time before performing the surgery, surgical approach, position on operating table, time of surgery, intraoperative bleeding, hospitalization time, intraoperative and postoperative complications. Follow-ups were performed at 1, 3, 6, 12 months, then annually. The clinical-functional outcome was assessed with the Merle d’Aubigne Postel score (MAP) modified by Matta; while the radiological outcome with the Matta Radiological Scoring System (MRSS). A Chi-square test was utilized to examine associations between parametric variables.ResultsWe included 34 patients, mean age 62.1, with an average follow-up of 20.7 months. The most frequent traumatic mechanism was road trauma. There were 15 isolated anterior columns and 19 associated patterns. There were 5 cases of associated visceral injuries, and 10 cases of other associated skeletal fractures. All patients were in the supine position. The surgical approach used was the AIP in all cases, with the addition of the first window of the ilioinguinal approach in 16 cases and of the Kocher-Langenbeck approach in 2 cases. The average time before performing the surgery was 8.5 days. The mean time of the surgery and the mean length of stay after surgery were 227.9 min and 8.2 days, respectively. There weren’t cases of intra-operative complications, while there were postoperative complications in 5 patients. The MRSS was judged anatomical in 26 cases, imperfect in 7 cases and poor in 1 case. The average MAP value was 15.2. We observed a significant relationship between the radiological outcome and the clinical outcome (p < 0.05).ConclusionsThe QLS plates in association with the AIP approach represent an effective treatment strategy for the treatment of acetabular fractures with anterior involvement.

Intrapelvic Pseudotumor Causing Neuropathy and Vascular Obstruction After Revision Total Hip Arthroplasty: A Case Report

Background: There is a growing body of recent literature regarding the occurrence of pseudotumors associated with modular junctions and various bearing surfaces after total hip arthroplasty (THA). Revision surgery is often technically challenging and high complication rates have been reported. The optimal management of these patients and outcomes after operative treatment remain poorly understood. Methods: We report the case of a 77-year-old male with progressive unilateral lower extremity swelling, pain, and neuropathy 9 years after revision THA for polyethylene liner wear. Imaging and biopsy confirmed a massive intrapelvic pseudotumor exerting compressive effects. Radiographs demonstrated extensive femoral and pelvic osteolysis without evidence of component loosening. Debulking of the intrapelvic portion of the pseudotumor was performed via the lateral window of the ilioinguinal approach with component retention. Results: Debulking of the intrapelvic mass resulted in resolution of symptoms. One year postoperatively the patient reported pain free ambulation using a walker and no recurrence of symptoms. Radiographs demonstrated stable THA components in comparison with preoperative films. Discussion and Conclusion: This case demonstrates a rare finding of intrapelvic pseudotumor causing neurovascular compression after revision THA. Clinicians should be aware of intrapelvic pseudotumor as a possible cause of limb swelling and neuropathy, and that debulking of the mass is a potential treatment option in the setting of well-fixed implants.

Mid-term effectiveness of periacetabular osteotomy through modified ilioinguinal approach for acetabular dysplasia in adults

To investigate the mid-term effectiveness of periacetabular osteotomy (PAO) through modified ilioinguinal approach for acetabular dysplasia in adults. Between January 2016 and December 2018, 39 patients (43 hips) with acetabular dysplasia who met the selection criteria were enrolled in the study and their clinical data were retrospectively analyzed. All patients were treated with PAO via modified ilioinguinal approach (firstly, the skin and superficial facia were cut via the traditional ilioinguinal approach, and the deep tissues were cut via the modified iliac-femoral approach). There were 3 males (3 hips) and 36 females (40 hips) with an average age of 36 years (range, 18-51 years). Among them, 35 cases of lesions involved single hip and 4 cases of lesions involved bilateral hips. The disease duration ranged from 4 to 96 months, with a median of 18 months. According to the modified Tönnis grading for osteoarthritis, 35 hips were classified as grade 0, 6 hips as grade Ⅰ, and 2 hips as grade Ⅱ. All patients had different degrees of hip pain. The preoperative visual analogue scale (VAS) score of pain was 4.7±0.8, and the modified Harris hip score was 78.5±8.6. The lateral centre-edge angle (LCEA) was (10.52±10.83)°, and the acetabular index (AI) was (26.89±9.07) °. The operation time, intraoperative blood loss, and the incidence of complications were recorded. LCEA, AI, and the progression of osteoarthritis were reviewed by X-ray films. The function and pain of hip joint were evaluated by modified Harris hip score and VAS score. All operations were successfully completed. The operation time was 90-150 minutes, with an average of 130 minutes. The volume of intraoperative blood loss was 350-600 mL, with an average of 500.6 mL. All patients were followed up 17-52 months, with an average of 32.7 months. Postoperative numbness of the lateral femoral cutaneous nerve occurred in 3 cases, and no other complications occurred. At last follow-up, the modified Harris hip score was 97.7±3.7 and VAS score was 0.9±1.1, both of which were better than those before operation ( P<0.05). At 1 year after operation, X-ray films showed that the all osteotomies healed. In term of the modified Tönnis grading for osteoarthritis, 1 hip downgraded from grade 1 to grade 0, while the remaining hips stayed unchanged. At last follow-up, LCEA and AI were (27.54±8.49) ° and (11.30±5.53) °, respectively, which were significantly different from those before operation ( P<0.05). PAO through modified ilioinguinal approach is effective in relieving pain and restoring hip function in adults with acetabular dysplasia, which can overcome the disadvantages of the traditional ilioinguinal approach, and may delay the development of osteoarthritis.
