Anterior peri-sacroiliac joint osteotomy in the treatment of malunion and nonunion of complex pelvic ring fracture: techniques and preliminary results

PurposeTo introduce anterior peri-sacroiliac joint osteotomy (APSJO) through the lateral-rectus approach (LRA) for treating pelvic fracture malunion and nonunion, and to evaluate the safety, feasibility, and potential effectiveness.MethodsData of 15 patients with pelvic fracture malunion and nonunion who underwent treatment by APSJO were selected and analyzed. The reduction quality was assessed using the Mears and Velyvis criteria, while the pre-operative and post-operative function was revealed by the Majeed scoring system. The British Medical Research Council (BMRC) grading system was recruited for the evaluation of lumbosacral plexus function.ResultsThe average operative duration was 264.00 ± 86.75 min, while the intra-operative blood loss was 2000 (600, 3000) mL. Anatomical reduction was complete in three cases, satisfactory in ten cases, and unsatisfactory in two cases. Among the seven patients with lumbosacral plexus injury, the pre-operative Majeed grades were good in two cases, fair in two cases, and poor in three cases, while the post-operative Majeed grades were excellent in three cases, good in three cases, and fair in one case. Muscle strength recovered to M5 in two cases, M4 in three cases, and showed no recovery in two cases. The pre-operative Majeed grades were good in five cases, fair in two cases, and poor in one case of the series without lumbosacral plexus injury, while the post-operative Majeed grades were excellent in seven cases and good in one case.ConclusionAPSJO through LRA may be a feasible strategy for treating pelvic fracture malunion and nonunion with promising application.

To study the outcome of sacro-iliac percutaneous screw fixation in unstable fractures of pelvic injuries

Percutaneous fixation of sacroiliac joint fractures and closed reduction gives advantages of limited blood loss, minimal invasion of compromised soft tissue, decreased infection rates and reduced operation time. The purpose of this study is to determine the outcome of sacroiliac percutaneous screw fixation of pelvic injuries in unstable fractures.This study was conducted at Tirunelveli medical college hospital from 2017 to 2019 in patients underwent sacro-iliac percutaneous screw fixation in unstable fractures of pelvic injuries. Functional assessment of patients with Pelvic fractures was assessed by Majeed Score Scale. Patients follow up was taken at 4, 8, 12 weeks, 6 months and 1 year. The study included 22 patients with ages ranged from 16-70 years with the mean age range of 39 years with 16 males and 6 females. Mode of injury was a road traffic accident in 86.36% of cases and fall from height in 13.64%. As per the Majeed scoring system all patients were clinically evaluated. The overall Majeed score was excellent in 77.27%, while good in 13.63% and poor in 9.09% of cases. As per Matta and tornetta postoperative radiological evaluation was carried out. Percutaneous iliosacral screw fixation and anatomic reduction give better stability in unstable sacroiliac joint injuries allowing good functional outcomes and early mobility. For sacral fracture and sacroiliac, joint injury with C arm guidance percutaneous iliosacral screw fixation is a minimally invasive and safe technique.

Lateral Compression Type 2 Pelvic Fractures-A Clinical Study of Fracture Displacement Measurement and Closed Reduction.

ObjectiveTo evaluate the displacement in four lateral compression type 2 (LC2) fracture subtypes (iliac wing and three kinds of crescent fractures) and to investigate the appropriate closed reduction for treatment using a pelvic reduction frame.MethodsA total of 71 patients with LC2 pelvic fractures from February 2014 to November 2019 were included in this retrospective cohort study. Preoperative X‐ray and computed tomography data were used to assess the direction of the fracture displacement and the sacroiliac joint dislocation. The fractures in all patients were reduced with a pelvic reduction frame and fixed with percutaneous screws as well as an anterior subcutaneous pelvic ring internal fixator. Two different closed reduction strategies were adopted, one was first longitudinal traction and then transverse traction, the other was first transverse traction then longitudinal and LC2 traction. The Matta score system was used to evaluate the postoperative X‐ray and the Majeed score system was used for follow‐up evaluation.ResultsA total of 13 iliac wing fractures (86.7%) and 16 Day type 1 fractures (94.1%) were vertically stable with only internal displacement, the ring width displacements were 5 (3, 8.75) and 8 (4, 12) mm, the posterior superior iliac spine (PSIS) differences were 0 (0, 0) mm and 0 (0, 0) mm. A total of 21 Day type 2 fractures (95.5%) and 16 Day type 3 fractures (94.1%) were characterized by cephalic and dorsal fracture dislocation on the basis of internal displacement, the ring width displacements were 6 (4.25, 12) and 4 (0, 7.5) mm and the PSIS differences were 4 (2, 5) and 0 (0, 3.75) mm. Based on the Matta scores, excellent reduction was achieved in 51 patients, good reduction in 17 patients, and poor reduction in three patients. The average Majeed score was 91.6, with a minimum outpatient follow‐up of 12 months (average 31.6 months).ConclusionLC2 fractures involve two different kinds of fracture displacement: internal displacement only and a combination of internal, cephalic, and dorsal dislocation through the sacroiliac joint. Good clinical outcomes can be achieved for LC2 fractures using two different closed reduction strategies.

Is Percutaneous Screw Fixation with 6.5 mm Cannulated Cancellous Screws a Viable Option in Pelvic Ring Fractures?

Background Historically, internal fixation in pelvic ring fractures has been proven to be better in outcome than both external fixation and conservative management. In an attempt to overcome the morbidity of extensile surgical approaches, percutaneous fixation of the pelvis has been receiving increasing attention. The aim of the study was to assess the functional outcome in patients with pelvic ring fractures treated with percutaneous screw fixation. Methods The study included 12 patients of pelvic ring fracture admitted at NSCB medical college, Jabalpur (Madhya Pradesh) from December 2019 to October 2021, all treated percutaneously with cannulated cancellous screw fixation. Four patients had Tiles type C1 injury, 4 patients with type C2, 2 with type B1 and 2 with type A2 injury. Functional assessment was done using the Majeed Scoring system at preoperative, at 3 weeks, 6 weeks, and 3 months postoperatively. Results Functional outcome score at 3-month follow-up was poor in 8% patients, fair in 8% patients, good in 33.3% patients, and excellent in 50% patients. Pain was the most frequent complaint on follow-up. Conclusion Fixation of acute pelvic ring injuries with 6.5 mm cc screws using percutaneous technique offers favorable functional outcome and can be performed in hemodynamically unstable patients.

A clinical and biomechanical comparison of INFIX plus single versus double sacroiliac screw fixation for unstable pelvic ring injury

BackgroundThe aim of this study is to compare the clinical and biomechanical outcome of INFIX plus single with two sacroiliac screw fixation for unstable pelvic fractures of Type C.MethodsSixteen cadavers were randomly subjected to INFIX plus single or double sacroiliac screw fixations and then mounted onto the ElectroForce loading machine under different vertical loads. To investigate the clinical outcomes of the two techniques, nineteen patients were retrospectively analyzed. The main outcome measures were postoperative radiographic reduction grading (using the Tornetta and Matta grading system), functional outcome (using the Majeed scoring system), and incidence of complications.ResultsIn the biomechanical study, INFIX plus double sacroiliac screw fixation showed better biomechanical stability than fixation with a single sacroiliac screw (p < 0.05). In our clinical case series, all 19 patients had bony union 6 months after the operation. INFIX plus double sacroiliac screw fixation also demonstrated a better functional outcome and a higher radiographic satisfactory rate than INFIX plus single sacroiliac screw fixation (79.25 ± 5.47; 91.33 ± 4.97; p < 0.05), (77.78% vs. 60%; p = 0.05). One patient in INFIX plus single-screw fixation group had screw loosening at 6-month follow-up postoperatively. One case in each group suffered heterotopic ossification and the lateral femoral cutaneous nerve paralysis, and one patient suffered from infection.ConclusionINFIX plus double sacroiliac screw fixation demonstrated more stability in cadaveric biomechanical analysis and better clinical outcomes than INFIX plus single sacroiliac screw fixation.

Minimally Invasive Percutaneous TightRope® System Fixation for an Unstable Posterior Pelvic Ring: Clinical Follow‐up and Biomechanical Studies

ObjectiveTo evaluate the mechanical stability and clinical efficacy of minimally invasive percutaneous TightRope® systems applied via gun‐shaped reduction forceps for unstable posterior pelvic ring fractures.Materials and methodsThis study consists of two parts: a clinical retrospective study and a randomized controlled biomechanical test. For the clinical study, a retrospective analysis of posterior pelvic ring fractures was performed between June 2015 and May 2020. Eighteen patients underwent surgery using two TightRope® systems to fix a broken posterior pelvic ring because of unstable AO type C1 and C2 pelvic ring fractures. The patients were followed up for at least 2 years, and all patients were evaluated using the Majeed scoring system and vertical displacement. In the biomechanical tests, six embalmed adult pelvic specimens were used. The fractures were subjected to TightRope®, IS screw, and TBP fixation in a randomized block design. The specimens were placed in a biomechanical testing machine in a standing neutral posture. A cyclic vertical load of up to 500 N was applied, and the displacement of the specimens was recorded by the testing machine. The ultimate load in each group of specimens was recorded. The displacement and ultimate load were compared and analyzed by statistical methods.ResultsAt a mean follow‐up of 38.89 ± 8.72 months, the functional Majeed score was excellent in 14 patients and good in four patients. The final radiological examinations showed that the outcome was excellent in 14 patients and good in four patients. In these patients, no serious clinical complications were found. Weight‐bearing was delayed in four patients. In biomechanical tests, the displacement of the specimens fixed with TightRope® was significantly lower than that of the specimens fixed with TBP (P < 0.05) when the load ranged from 300 to 500 N. The displacement in the IS screw group was significantly lower than that in either the TBP or TightRope® group (P < 0.05) when the load ranged from 0 to 500 N. The ultimate load in the IS screw group (1798 ± 83.53 N) was significantly greater than that in the TBP group (1352 ± 74.41 N) (t = 9.78, P < 0.0001) and the TightRope® group (1347 ± 54.28 N) (t = 11.11, P < 0.0001). However, no significant difference was observed between the TightRope® and TBP groups (t = 0.13, P = 0.90).ConclusionPercutaneous posterior TightRope® system shows strong stability in mechanical experiments and shows good results in clinical follow‐up while this system has certain advantages in lower surgical requirements and lower risk of related nerve and vascular structural damage.

Lumbopelvic fixation with S2 alar-iliac screws for U-shaped sacral fractures

ObjectiveTo investigate the surgical methods and clinical effects of lumbopelvic fixation (LPF) with S2 alar-iliac (S2AI) screws for U-shaped sacral fractures. MethodsFrom December 2019 to August 2020, 14 patients with U-shaped sacral fractures were treated with LPF using S2AI screws. Demographics, fracture classification, mechanism of injury, surgical treatment, complications and clinical results were assessed. All patients had a LPF with or without nerve decompression. The reduction quality was evaluated according to the Matta criteria. Neurological function was evaluated according to the Gibbons grading. The activities of daily life were evaluated according to the Majeed scoring system at the last follow-up. ResultsAmong 14 consecutive patients with U-shaped sacral fractures, the age at injury ranged from 13 to 72 years (average 30.3 ± 17.5 years). There were 4 males and 10 females. All patients were followed up for 6–15 months (average 7.8 ± 2.7 months). Thirteen patients were fixed with bilateral S2AI screws, and one patient was fixed only unilaterally due to unilateral spinopelvic dissociation. The excellent and good rate of postoperative pelvic reduction quality was 92% (excellent 10, good 3, fair 1). At the latest follow-up, the excellent and good rate of pelvic function was 100% (excellent 9, good 5) and all patients achieved different extents of neurological recovery. One patient had a postoperative superficial surgical site infection, which healed after debridement. Radiological examination at 3–6 months after operation showed that all fractures had healed. No complications were found in any patients during follow-up, such as implant fracture, loss of reduction, deep wound infection, wound dehiscence and screw protrusion discomfort. ConclusionLPF with S2AI screws for the treatment of U-shaped sacral fractures has exhibited distinct advantages, including firm fixation, a low rate of surgical site complications and satisfactory clinical efficacy. This approach provides sufficient stability to accelerate the commencement of postoperative rehabilitation.

RETRACTED ARTICLE: Failure of internal fixation of the anterior ring for unstable pelvic fractures, the experience of a single institute

BackgroundThis study aimed to share our experience of anterior ring fixation failure for unstable pelvic fractures and propose corresponding treatment strategies.MaterialsFrom January 2009 to December 2018, 93 charts of patients with pelvic fractures were retrospectively reviewed. Patients with failure of the anterior ring internal fixation within 3 months after initial surgery were analyzed. Quality of reduction was evaluated using the Majeed scoring system. Patients aging ≥ 18 years, with unstable pelvic fractures, Tile classification type B and type C pelvic fractures, combined injury of other organs that did not affect the operation and without important neurovascular damage were included. The exclusion criteria included: (1) pathological fracture, or combined with pelvic bone tumor or severe osteoporosis; (2) femoral fracture and thoracolumbar fracture; (3) open pelvic fracture; (4) Morel-Lavallée injury; (5) complicated acetabular fracture. The quality of the reduction of the anterior pelvic ring injury was evaluated on the x-ray film using the Majeed scoring system.ResultsAccording to the Tile classification of fracture, there were 23 cases of type B1, 17 cases of type B2, 11 cases of type B3, 28 cases of type C1, 6 cases of type C2, and 8 cases of type C3. The duration from injury to pelvic internal fixation ranged from 5 to 28 days. Seven out of 93 patients experienced failure of internal fixation of the anterior pelvic ring within 3 months, including 2 patients fixed with an external fixator and 5 patients fixed with a plate. Five patients undergoing revision surgery were followed up for 6–36 months with an average of 18 months. According to Majeed’s score at the last follow-up in the 5 patients undergoing revision surgery, there were 2 cases of excellent, 2 cases of good, 1 case of fair. The excellent and good rate reached 80%.ConclusionThe treatment of complicated unstable pelvic fractures requires performing internal fixation surgery within 2 weeks. It is necessary to make a preoperative plan and stabilize the posterior ring first, avoiding a single steel plate crossing the pubic symphysis.

Acetabular Fractures with Central Hip Dislocation: A Retrospective Consecutive 50 Case Series Study Based on AO/OTA 2018 Classification in Midterm Follow-Up.

Introduction Management of acetabular fractures is challenging, especially when a medial acetabular fracture is complicated by central hip dislocation. We retrospectively investigated the clinical outcome and risk factors of secondary hip osteoarthritis requiring total hip arthroplasty after the surgical treatment of acetabular fractures with central hip dislocation. Materials and Methods The medical records of all patients who had acetabular medial wall fractures with central hip dislocation treated with open reduction and internal fixation by a single surgeon between January 2015 and June 2017 were reviewed. Surgical reduction was performed with the modified Stoppa with/without the Kocher-Langenbeck (KL) approach. Patients were followed for a minimum of three years, and the Majeed scoring system was used for functional evaluation. Multivariate logistic regression analysis was used to assess the association of patients' characteristics with the likelihood of advanced posttraumatic arthritis developing with conversion to total hip arthroplasty. Results Fifty patients were included in this study, with disease classified as AO/OTA 2018 62B/62C. Thirty-five patients (70%) had good or excellent Majeed pelvic scores. Eleven patients (22%) eventually received total hip arthroplasty because of end-stage posttraumatic arthritis. Three risk factors identified for total hip arthroplasty were male sex, initial marginal impaction, and sciatic nerve injury. Kaplan-Meier survivorship analysis estimated that the cumulative probability of free-from-end-stage arthritis was 78% (95% confidence interval, 73%–90%) at the 5-year follow-up. Conclusion Surgical fixation with the modified Stoppa and the KL approach for acetabular medial wall fractures with central hip dislocation is an effective approach with a satisfactory functional outcome. A prodromal factor was marginal impaction concomitant with articular damage. The trauma of high axial loading and the occupational distribution (males performing heavy manual labor and heavy lifting) with preoperative sciatic nerve injury increased the odds of developing end-stage arthritis.

Применение транспедикулярной спинальной системы и блок-решетки при оперативном лечении посттравматической деформации таза: случай из практики и краткий анализ литературы

Introduction The problem of treating chronic unstable pelvic injuries is characterized by the complexity of delayed one-step or staged reduction, difficulties in choosing the technology and treatment options, complexity of selecting criteria for evaluating planning along with the effectiveness of treatment. The use of spinal systems to perform reduction manipulations and fixation of the pelvis is described in few clinical observations. Therefore, the assessment of the effectiveness of the sequential use of various fixation systems in one patient was regarded by the authors as a rare opportunity and determined the purpose of the study. Purpose Demonstration of the possibilities of various osteosynthesis methods and their combination in reconstructive surgery of the pelvis in a case of its severe chronic injury. Materials and methods We present a clinical case and a brief analysis of the literature. This is a case of a patient with posttraumatic pelvic deformity and imbalance syndrome as a leading component of pelvic ring deformity. The effectiveness of reconstruction options, including those with the use of spinal systems, was analyzed. The treatment was assessed with radiological study methods (X-ray and CT) with balance evaluation on a digital platform and functional scores for the quality of life. Results Correction of frontal deformity of the pelvis was achieved with compensation for a relative shortening of the left lower extremity, restoration of the center of rotation of the hip joints, and relief of pain in the lumbar region. The functional state according to the Majeed score system and clear radiological signs of stabilization of the pelvic ring while maintaining the position of the acetabulum in the frontal plane prove the effectiveness of hybrid osteosynthesis with the use of spinal fixation systems. Conclusion The leading syndromic complexes are instability with clinical manifestations of non-union and pain along with an imbalance syndrome, manifested by a gross deformation of the pelvic ring. Syndromic evaluation determines the tactics of surgical treatment while a detailed planning of the sequence of intervention, choice of the level of osteotomy, combination of osteosynthesis options using spinal fixation systems provide the solution of reconstructive pelvic surgery tasks in one session.

Comparison of effectiveness of anterior subcutaneous internal fixator and plate internal fixation for unstable anterior pelvic ring fractures

To compare the effectiveness of anterior subcutaneous pelvic internal fixator (INFIX) and plate internal fixation in treatment of unstable anterior pelvic ring fractures. The clinical data of 48 patients with unstable anterior pelvic ring fractures who met the selection criteria between June 2014 and December 2019 were retrospectively analyzed. Among them, 21 cases were treated with INFIX (INFIX group), and 27 cases were treated with plate (plate group). There was no significant difference in gender, age, body mass index, cause of injury, time from injury to operation, Injury Severity Score (ISS), and fracture type between the two groups ( P>0.05). The operation time, intraoperative blood loss, fracture healing time, partial weight-bearing time, and complete weight-bearing time were recorded and compared between the two groups. Matta standard was used to evaluate the quality of fracture reduction, and Majeed score system was used to evaluate the functional recovery of pelvic fracture after operation. The patients in both groups were followed up for an average of 12.5 months (range, 6-16 months). The operation time and intraoperative blood loss in INFIX group were significantly lower than those in plate group ( t=-11.965, P=0.000; t=-20.105, P=0.000). There was no significant difference in the quality of fracture reduction, fracture healing time, partial weight-bearing time, and complete weight-bearing time between the two groups ( P>0.05). At 14 weeks after operation, there was no significant difference in the scores of pain, working, standing and walking, and total scores between INFIX group and plate group ( P>0.05), but there were significant differences in sitting and sexual intercourse scores ( t=-4.250, P=0.003; t=-6.135, P=0.006). The incidences of lateral femoral cutaneous nerve injury, femoral nerve injury, and heterotopic ossification were significantly higher in INFIX group than in plate group ( P<0.05), while the incidence of incision infection was lower in INFIX group than in plate group ( P<0.05). Compared with the plate internal fixation, the INFIX internal fixation can obtain the similar effectiveness for the unstable anterior pelvic ring fracture and has the advantages of shorter operation time, less blood loss, and lower risk of infection.

Application of anterior subcutaneous internal fixator combined with posterior plate in treatment of unstable pelvic fractures

To investigate the effectiveness of anterior subcutaneous internal fixator combined with posterior plate in the treatment of unstable pelvic fractures. Between January 2015 and January 2019, 26 cases of unstable pelvic fractures were treated with anterior subcutaneous internal fixator combined with posterior plate. There were 16 males and 10 females, with an average age of 42.8 years (range, 25-66 years). According to the Tile classification, 9 of them belonged to type B2, 6 to type B3, 7 to type C1, 3 to type C2, 1 to type C3. The injury severity score (ISS) was 6-43 (mean, 18.3). Four cases combined with brain injury, 7 with limb fractures, 3 with hemopneumothorax, 1 with sciatic nerve injury. The time from injury to operation was 4-12 days (mean, 6.4 days). The intraoperative blood loss, operation time, and the complications were recorded. The fracture reduction and the postoperative function of patients were evaluated. All patients were followed up 12-26 months (mean, 16.8 months). The operation time was 65-142 minutes (mean, 72.5 minutes) and the intraoperative blood loss was 42-124 mL (mean, 64.2 mL). There were 2 cases of unilateral lateral femoral cutaneous nerve stimulation, 1 case of femoral nerve paralysis, and 1 case of superficial infection of incision, which were cured after corresponding treatment. X-ray films showed that all fractures healed at 3 months after operation. At last follow-up, according to Matta criteria for fracture reduction, the results were excellent in 8 cases, good in 15 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 88.5%. According to Majeed scoring system for pelvic function, the results were excellent in 10 cases, good in 12 cases, and fair in 4 cases, with an excellent and good rate of 84.6%. For unstable pelvic fractures, the anterior subcutaneous internal fixator combined with posterior plate has fewer operative complications, high security, and achieve good effectiveness.

Outcome of Percutaneous Iliosacral Screw Fixation of Sacroiliac Joint Disruptions

Background: Closed reduction and percutaneous fixation of sacroiliac joint disruptions has the advantage of minimal invasion of compromised soft tissue, limited blood loss, decreased operation time, and decreased infection rates. The objectives of this study was to evaluate the functional and radiological outcome after percutaneous fixation of sacroiliac joint (SIJ) disruptions by cannulated screw. Objectives: Management of sacroiliac joint disruptions by closed reduction and percutaneous fixation by iliosacral screw. Patients and Methods: This study was carried out in Orthopedic Surgery Department, Zagazig University Hospitals, during the period from May 2018 to September 2019. The study included 12 patients with age ranged from 19-59 years, 7 males and 5 females. Mode of injury was road traffic accident in 58.3% of cases and fall from height in 41.7%, right side was affected in 6 patients, left side was affected in 5 patient and one patient was affected bilaterally. Results: All patients were evaluated clinically according to Majeed scoring system. The overall Majeed score was satisfactory in 75%, while unsatisfactory results were in 25% of cases. Postoperative radiological evaluation was done according to Matta and tornetta. 25% patients had excellent results, 50% had good results and 25% had fair results. Postoperative complication were superficial infection in 6 patients and one patient had chronic posterior pelvic pain. Conclusion: Percutaneous method of fixation of the SIJ disruptions is effective and favourable method ensuring low operative time, high chance of obtaining stable pelvic ring with minimal blood loss, low incidence of complications and good rehabilitation results especially early mobilization.

Minimally Invasive Screw Fixation of Unstable Pelvic Fractures Using the "Blunt End" Kirschner Wire Technique Assisted by 3D Printed External Template.

Objective This study aimed to determine the accuracy and safety of the “blunt end” Kirschner wire (KW) technique for the minimally invasive treatment of unstable pelvic fractures with the assistance of a 3D printed external template. Methods Clinical data of 28 patients with unstable pelvic fractures between January 2016 and January 2018 were retrospectively analyzed. There were 6 cases of B1, 10 of B2, 8 of C1, and 4 of C2 fractures, all of which received surgical treatment. The “blunt end” KW technique with a 3D template was adopted for the minimally invasive placement of the iliosacral (IS) or superior ramus screws. The number of intraoperative fluoroscopies, surgical time, and complications were recorded. Postoperative reduction was assessed using the Matta criteria, and the Majeed score system was used to evaluate postoperative functional recovery. Results The average number of fluoroscopies was 35 per patient, and the average surgical time was 85.2 min. A total of 19 S1 and 28 S2 IS screws were inserted. Eleven antegrade superior ramus screws and 4 retrograde screws were placed in 11 patients, and anterior subcutaneous internal fixation (INFIX) was used to fix the anterior pelvic ring in 17 patients. All patients were followed up for an average of 18 months. Postoperative reduction was evaluated by Matta's criteria: excellent in 16 cases, good in 9 cases, and fair in 3 cases. The Majeed score was used in the last follow-up to evaluate functional recovery: excellent in 13 cases, good in 10 cases, fair in 4 cases, and poor in 1 case. There were no cases of operative vascular injury. Conclusion The “blunt end” KW technique with a 3D printed external template is a safe and effective method for the placement of IS and superior ramus screws in unstable pelvic fractures with minimized surgical duration and radiation exposure.

Anterior subcutaneous internal fixator (INFIX) versus plate fixation for pelvic anterior ring fracture

The aim of this study was to compare the clinical outcomes in patients with unstable anterior pelvic ring fractures after treatment with anterior subcutaneous internal fixator (INFIX) or plate fixation. We performed a retrospective study from August 2015 to October 2017. A consecutive series of 74 patients who underwent surgical treatment of their anterior pelvic ring (35 treated with INFIX and 39 treated with plates) were studied. Data collected included patients’ demographic data, injury severity score (ISS), AO/OTA classification, injury mechanism, time to surgery, procedure time, and blood loss. The quality of postoperative reduction were assessed by postoperative radiographs using the Tornetta and Matta method. Functional outcome was evaluated using Majeed scoring system. In the INFIX group, ten patients developed LFCN paralysis, one patient suffered from superficial infection. Three screw loosening cases and two wound infection cases occurred in the plate group. INFIX is relatively minimally invasive and time-saving than the reconstruction plate in the treatment of anterior pelvic ring fracture. However, plate fixation increases the rate of anatomic reduction of the pelvic anterior ring fracture. Plates also provide a higher functional outcome compared with INFIX. INFIX is especially suitable in patients with urological injury, which can also decrease the wound infection rate.

Sacroiliac screw versus a minimally invasive adjustable plate for Zone II sacral fractures: a retrospective study

ObjectiveFracture line of the sacrum always involves the Zone II region because sacral foramina are anatomically and physiologically weak regions of the sacrum. The purpose of this study is to compare the therapeutic effects of a sacroiliac screw and a minimally invasive adjustable plate (MIAP) for Zone II sacral fractures. MethodsPatients with unilateral Zone II sacral fractures fixed with a unilateral sacroiliac screw or MIAP from August 2009 to January 2016 were recruited into this study and were divided into two groups: group A (sacroiliac screw) and group B (MIAP). Surgical time, blood loss, frequency of intraoperative fluoroscopy, and relative complications were reviewed. Radiographs and CT scans were routinely acquired to evaluate the fracture displacement and reduction quality. Fracture healing was evaluated in the radiographs at each follow-up. Functional outcome was assessed based upon the Majeed scoring system at the final follow-up. ResultsThirty-one patients in group A and thirty-nine patients in group B were included in this study. No significant differences in average surgical time (P = 0.221) or blood loss (P = 0.234) were noted between group A and group B. The mean frequency of intraoperative fluoroscopy was 15.74±2.98 in group A and 6.08±1.94 in group B (P = 0.000). All fractures healed well within four months in all patients, and the healing time exhibited no significant difference between the two groups (P = 0.579). Satisfactory rates of reduction quality and functional outcome were not statistically different between the two groups (P > 0.05). The complication rate was 16.13% (5/31) in group A and 5.13% (2/39) in group B (P = 0.222). ConclusionMIAP has a fixation effect and exhibits reduction potential for Zone II sacral fractures. Favourable radiographic and functional results could be obtained through the MIAP technique, which is easy to conduct without pre-contouring. Compared with the unilateral S1 sacroiliac screw technique, repeated projections and iatrogenic sacral injury can be avoided.

MODIFIED STOPPA APPROACH FOR PELVIC AND ACETABULAR FRACTURE TREATMENT.

ABSTRACTObjective:A retrospective review aims to investigate the operative methods and therapeutic effects of the modified Stoppa approach for treating pelvic and acetabular fractures.Methods:18 patients with acetabular fracture of the anterior column and pelvic anterior ring fracture underwent surgical treatment using the modified Stoppa approach. Some of the treatment was combined with the iliac fossa approach or rear K-L approach. Fracture reduction and postoperative function were evaluated using the Matta scoring standard and the Majeed scoring system. The Oxford Centre for Evidence-Based Medicine system was used to grade the literature review and create graded B recommendations.Results:Incision length was 6-12 cm (mean, 10 cm), operative duration was 50-150 minutes (mean, 85 minutes), and intraoperative blood loss volume was 400-1,000 ml (mean, 500 ml). 18 patients were followed up for 12-36 months post-operation. In the results of X-ray films, 12 cases were anatomical reductions and the remaining cases were satisfactory reductions. According to Majeed standard, 13 patients were excellent and five patients were good.Conclusions:Treatment using the modified Stoppa approach was suitable for anterior approaches, in which pelvic and acetabular fractures were sufficiently exposed, the fracture was conveniently reduced, less complications occurred, and curative effect was satisfactory. Level of evidence III, Retrospective comparative study.

A novel hybrid fixation (percutaneous anterior pelvic bridge with K-wire) for the treatment of traumatic pelvic ring injury: A prospective study

BackgroundThe aim of the study was to introduce a novel percutaneous technique for the treatment of pelvic ring injuries using a percutaneous anterior pelvic bridge (PAPB) with K-wire. MethodsFrom December 2010 to November 2016, a prospective study of 86 patients with anterior pelvic ring fracture (42 utilizing PAPB with K-wire and 44 utilizing PAPB). Patient data was retrieved from electronic charts. Radiological results were assessed based on the Matta criteria system to evaluate the quality of the reduction and time to union. Functional outcomes were evaluated using the Majeed scoring system. Postoperative complications were also recorded. ResultsAge, sex, cause of injury, type of fracture, functional recovery, American Society of Anesthesiologists classification, union time, Majeed scoring and complications did not differ significantly between the two groups. The quality of the reduction and pain scoring differed between groups (all p-values < 0.05). Group A got better reduction and less pain scoring. ConclusionsThe novel percutaneous technique with hybrid fixation using PAPB with K-wire is a successful alternative for the treatment of pelvic ring injuries, which results in better quality of reduction and less pain scoring outcomes comparing to PAPB. May the PAPB + K-wire could provide more stability.

Crescent fractures of the pelvis treated by open reduction and internal fixation: a critique of Day’s guidelines

Day's classification and treatment guidelines are considered the gold standard in crescent fractures of the pelvis. The objective of this study was to retrospectively evaluate 10 surgically treated crescent fractures of the pelvis in the context of Day's recommendations. This is a retrospective cohort study. Ten consecutive cases of crescent fractures that were treated surgically at a level 1 trauma center formed the cohort. Six were operated anteriorly, three posteriorly and one percutaneously. Classification and treatment strategy were compared to Day's guidelines. The minimum follow-up was 13months. Outcomes were assessed using the modified Majeed's scoring system. Three out of 10 cases were difficult to classify by Day's criteria. There were 4 type I, three type III and no type II cases. Our surgical strategy was independent of Day's recommendations in this series and based on ease of access, ability to restore the sacroiliac joint anatomy and other associated injuries. All the patients were mobilized early and the fractures united without any major incident. The results of these cases were quite good with outcome scores over 67/96. Assigning Day's classification to a given case can be difficult in up to 33% patients with crescent fractures due to the obliquity of the iliac fracture line in axial sections. Sacroiliac articular alignment is the primary factor determining the surgical approach. Besides the fracture configuration, additional factors like delay in surgery, locking of the fracture fragments, comminution of the iliac or sacral fragment as well as access to the additional injuries contribute to the decision making.

Pelvic Fracture - Results of Early External Fixation

Background : The behavior of pelvic ring fracture following surgical fixation has been very sparsely studied. Pelvic ring injuries, depending on their severity had been treated by variety of closed method. The purpose of the study is to assess the short-term functional outcome of pelvic ring fracture following surgical fixation. Method: Present prospective study consists of 62 patients of pelvic fracture admitted in department of orthopedics, NSCB medical college and hospital Jabalpur (M.P) during the period of Oct. 2010 to Sep. 2011. All patient of type A (stable) fracture treated by conservative method. Out of 40 patients of unstable pelvic fracture (involving pelvic ring) 14 were treated by surgical method. Out of 14 patients 4 were treated by external fixation, 8 by internal fixation, and 2 by combined external and internal fixation. Functional outcome assessment was done by Majeed Scoring System [1]. Results: Functional outcome score in surgically treated patient is excellent in 7 patients, good in 4, fair in 2, and poor in 1 patient at 3 month follow-up. Pain is the most common complaint after 3 month of surgical fixation, it is seen in 4 patients (28.57%) but only 1 patient changed his job because of this pain. Conclusion: Unstable Pelvic ring injury has poor outcome, it should be treated by operative methods for optimal functional outcome.
