Anterolateral minimally invasive hip approach offered faster rehabilitation with lower complication rates compared to the minimally invasive posterior hip approach—a University clinic case control study of 120 cases

INTRODUCTION The surgical approach used in total hip arthroplasty (THA) has been identified as a factor affecting the outcome. In our University Hospital, the posterior surgical approach is the gold standard. The Rottinger approach is an anterolateral approach which is truly minimally invasive, as it does not vertically cut any muscle fibers. The objective of this study was to determine the difference in surgical outcomes between the posterior hip approach and the Rottinger approach which was newly adopted at our Hospital. METHODS In a retrospective study, a total of 120 patients underwent THA; 60 patients using the Rottinger approach by the young consultant surgeon and another 60 patients using the standard posterior approach by the senior orthopaedic surgeon. Patients have been controlled for age, gender, and ASA grades. All preoperative demographic data showed no significant difference between the control and study groups. The following parameters were analyzed: incision length, duration of the surgery, intraoperative blood loss, WOMAC index, Harris Hip Score, range of motion at 3 and 12 months after surgery, time of quitting the crutches, and willingness for the contralateral hip arthroplasty. RESULTS WOMAC index, surgical time, and incision lengths have been without significant difference in both approaches. Intraoperative blood loss was significantly lower in the Rottinger group (CI: - 10.903, - 0.064). Harris Hip score was significantly higher (CI: 4.564, 12.973) in the Rottinger group at 3 months, but similar (CI: - 3.484, 2.134) at 12 months follow-up. At 3 months, active flexion and extension were significantly higher in the Rottinger group (CI: 0.595, 8.239; 2.487, 4.480, respectively), and active abduction and passive adduction (CI: - 5.662, - 0.338; - 6.290, - 1.410, respectively) in the posterior approach group. Patients in the Rottinger approach group on average quit crutches 3 weeks earlier and had no postoperative dislocations compared to 2 dislocations in the control group. CONCLUSION The Rottinger approach offered faster rehabilitation with less need for crutches and with lower complication rates.

Anterior and Posterior Approach Results for Treatment of Cervical Myelopathy in the Elderly: A 10-Year Experience in a Mexican Institution

Introduction: Degeneration of the cervical spine (CDSD) prevalence is nearly 90% by the 7th decade. This is the first research that compares the outcomes between the Anterior Approach (AA) and Posterior Approach (PA) to cervical myelopathy (CM) in the elderly. Materials and Methods: A retrospective observational study of electronic health records at the Hospital Central Sur de Alta Especialidad (HCSAE), PEMEX from January 2010 to May 2020 with patients older than 60 years submitted to cervical surgery. For the analysis we elaborated two groups according to the surgical approach: AA vs PA; we analyzed the trans-operative behavior, the immediate outcome, and after 3 months, 6 months, and 1 year. Results: As a total of 145 patients, the prevalence of CM in elderly was the 63.8% with a median age of 69 (64 - 75) years. We found statistical differences in strength outcome only in the P3m (p = 0.011), for sensitivity we found major prevalence of affection in the PA group. We didn’t report a significant difference in the Neck Disability Index (NDI) at all measures, but the PA presented a major incapacity. The Nurick scale results were significant in all stages (p . Discussion: Patients show significant improvements in outcome measures with either anterior or posterior surgery. Both approaches are highly efficacious in preventing neurologic deterioration and in most cases improve neurological function with appropriate postoperative management like rehabilitation, pain management, and psychological support. Conclusion: The patients submitted to surgical medullary decompression presented a favorable outcome despite the age and the higher prevalence of comorbidities; whereby we favor the surgical treatment in all patients in a case-to-case selection to generate a positive impact on functional outcomes.

Changes in serum creatine kinase and C-reactive protein after posterior and direct anterior approaches in total hip arthroplasty.

Some studies reported that measuring serum creatine kinase (CK) level is an objective method with which to determine the relative invasiveness of surgery. The purpose of this study was to evaluate the change in postoperative serum CK levels as a measure of whether the direct anterior approach (DAA) is less invasive than the posterior approach (PA) regarding postoperative rehabilitation. We prospectively recruited 71 women who were undergoing total hip arthroplasty, 47 were treated by the PA and 24 by the DAA. Serum CK and C-reactive protein (CRP) levels were measured preoperatively and 3 hours and 1, 4, 7, 10, and 14 days after the operation. The serum CK levels were significantly higher in the DAA group than in the PA group on postoperative days 1, 4, 7, 10, and 14. On postoperative day 4 and 7, the percentage of patients whose serum CK levels were above the normal range was 46.8% and 8.5% in the PA group and 95.2% and 45.5% in the DAA group. CK levels were significantly higher in the 2 weeks after THA by a DAA than after the same procedure by a PA indicating that DAA causes prolonged muscle damage. Although the DAA is considered to be a muscle-sparing approach this may not be the case and DAA may not actually be a minimally-invasive approach.

Operative approach influences functional outcome after DAIR for infected total hip arthroplasty.

To compare the functional outcome, health-related quality of life (HRQoL), and satisfaction of patients who underwent primary total hip arthroplasty (THA) and a single debridement, antibiotics and implant retention (DAIR) procedure for deep infection, using either the transgluteal or the posterior surgical approach for both procedures. The study was registered at clinicaltrials.gov (ID: NCT03161990) on 15 May 2017. Patients treated with a single DAIR procedure for deep infection through the same operative approach as their primary THA (either the transgluteal or the posterior approach) were identified in the Norwegian Arthroplasty Register and given a questionnaire. Median follow-up after DAIR by questionnaire was 5.5 years in the transgluteal group (n = 87) and 2.5 years in the posterior approach group (n = 102). Patients in the posterior approach group were less likely to limp after the DAIR procedure (17% vs 36% limped all the time; p = 0.005), had a higher mean Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function score (80 vs 71; p = 0.013), and were more likely to achieve a patient acceptable symptom state for the WOMAC function score (76% vs 55%; p = 0.002). In a multivariable analysis, the point estimate for the increase in WOMAC function score using the posterior approach was 10.2 (95% CI 3.1 to 17.2; p = 0.005), which is above the minimal clinically important improvement. The patients in the posterior approach group also reported better mean HRQoL scores and were more likely to be satisfied with their hip arthroplasty (77% vs 55%; p = 0.001). In patients treated with a single, successful DAIR procedure for deep infection of a primary THA, the use of the posterior approach in both primary surgery and DAIR was associated with less limping, better functional outcome, better HRQoL, and higher patient satisfaction compared with cases where both were performed using the transgluteal approach. The observed differences in functional outcome and patient satisfaction were clinically relevant. Cite this article: Bone Joint J 2020;102-B(12):1662-1669.

Lumbar Adding-on of the Thoracic Spine After Selective Fusion in Adolescent Idiopathic Scoliosis Lenke Types 1 and 2 Patients: A Critical Appraisal.

Retrospective cohort study. This study aimed to identify risk factors that predict lumbar curve adding-on in patients who had selective thoracic fusion. Selective thoracic fusion offers deformity correction of Lenke 1 and 2 thoracic curves and maintains lumbar range of movement. However, some patients may develop postoperative lumbar adding-on. This study included patients 18 years or younger that underwent spinal instrumentation for Lenke 1 and 2 curves. A total of 161 patients were included (147 females, 14 males). The mean age was 14.0 ± 2.1 years: 103 patients were Lenke 1, and 58 patients were Lenke 2 curves. Ninety-seven patients underwent posterior approach surgery, whereas 64 via anterior approach. In the posterior approach group, 79(81.4%) patients underwent selective fusion. Ten patients (6.2%) had lumbar curve adding-on, with nine females and one male. There were seven Lenke 1 and three Lenke 2 patients. All 10 patients were lumbar modifier (a), with 5 hypokyphotic patients. Selective fusion was done in nine patients. Lumbar adding-on was seen most commonly between 6 months to 1 year postoperative period (five patients). Two patients had adding-on because of incorrect distal fusion level, six were due to 1A-R curve, one due to the inadvertent fusion from the excessive long rod at the subjacent level. In multivariate analysis, hypokyphotic patients were at higher risk of lumbar adding-on (odds ratio = 9.2). Patients with Risser classification 0, 1, 2, 3 were also at higher risk of lumbar adding-on (odds ratio =6.1). The incidence of lumbar curve adding-on was 6.2%. Patients who were hypokyphotic and skeletally immature are nine times and six times more likely to have lumbar adding-on, respectively. This article examines adding-on in patients who had either anterior or posterior approach scoliosis surgeries, with follow-up stretching up to 10 years. This offers the rare opportunity to examine the natural history of the adding-on phenomenon.Level of Evidence: 3.

Heterotopic ossification after total hip arthroplasty: radiological comparison between a direct anterior approach without an orthopaedic table and a posterior approach.

Heterotopic ossification (HO) occurs in almost ⅓ of total hip arthroplasties (THAs). A direct anterior approach (DAA) with an orthopaedic table is less likely to cause HO than a posterior approach. Without an orthopaedic table, the exposure of the femur requires additional soft tissue release. Soft tissue trauma leads to the production of HO inductors. Our study evaluated the incidence of HO 6 months after THA and compared the results between DAAs without an orthopaedic table and posterior approaches. Retrospectively, 164 consecutive, primary THAs were included: 76 through a posterior approach and 88 through a DAA. The main objective was to measure the presence of HO on pelvis radiography 6 months after surgery. The incidence of HO was significantly higher in the DAA group than in the posterior approach group (47.7% vs. 27.6%, respectively; p < 0.01). The overall incidence of HO was 38.4%. No significant difference was found between the 2 approaches regarding the severity of HO. No significant risk factor for HO was identified other than the surgical approach. In our study, the incidence of HO after THA in patients undergoing DAA without an orthopaedic table was higher than in patients undergoing a posterior approach after 6 months of follow-up. This result is closely related to the surgical trauma. It suggests that the minimally invasive feature of a surgical approach cannot be dissociated from the overall conditions in which it is performed.

30. Retrospective comparative analysis of combined vs only posterior approach for treating severe scoliosis

BACKGROUND CONTEXT Studies comparing two-stage approach (first anterior then posterior) and only posterior approach for treating scoliosis are rather scarce, with shorter follow-up and lack of clinical data. PURPOSE The purpose of the retrospective study was to compare long-term clinical and radiological outcomes in comparable groups of patients when using different surgical approaches (two-stage and only posterior) for idiopathic scoliosis operations. STUDY DESIGN/SETTING A retrospective, one center, institutional review board approved study. PATIENT SAMPLE A total of 348 patients with idiopathic scoliosis were operated on using CD hybrid instrumentation with pedicle screw and hooks. Only patients with curvatures ≥61 ° were analyzed and divided in two groups: two-stage surgery (N=30) and one-stage surgery (N=46). OUTCOME MEASURES Not applicable. METHODS Comparisons between groups were made regarding the following variables: gender, age at surgery, follow-up duration, number of segments, duration of surgery, hospitalization time, and different radiological parameters. The anteroposterior (AP) and lateral standing radiographs were used to check for deformity; numbers of instrumented segments, curve flexibility (bending test), coronal and sagittal balance and rotation deformity. The coronal balance was measured as the distance between the C7 plumb line and the perpendicular line drawn from the center of S1. The sagittal balance was measured as shortest distance between the C7 plumb line and the posterior superior corner of the S1 body. For both coronal and sagittal measurements, balance was considered abnormal if the distance was greater than 2 cm. Measurement of vertebral rotation was done using the Nash-Moe method. All patients were invited in an outpatient clinic to fill out a short-form health survey (SF-36) and to make a control X-ray image of the whole spine. RESULTS No statistically significant difference was observed in correction between two-stage group (average correction 69%) and only posterior approach group (average correction 66%). However, there were statistically significant differences regarding hospitalization time, duration of the surgery and the number of instrumented segments. The SF-36 scores were similar and there were no statistically significant differences between different health dimensions among compared groups. The greatest differential found in mean scores was for energy and vitality. CONCLUSIONS Two-stage surgery has only a limited advantage in terms of postoperative correction angle compared to the posterior approach. Posterior instrumentation and correction is satisfactory, especially taking into account that the patient is subjected to only one surgery.

The direct anterior approach for simultaneous bilateral total hip arthroplasty: a short-term efficacy analysis

PurposeCompared to the posterior approach (PA), the direct anterior approach (DAA) can achieve better clinical outcomes for total hip arthroplasty (THA). The purpose of this study was to investigate whether the same advantages associated with the DAA could be attained in patients undergoing simultaneous bilateral THA.MethodWe retrospectively reviewed 89 patients who underwent one-stage bilateral THA through the DAA (group A, n = 46) and through the PA (group B, n = 43) between June 2015 and November 2017 at our institution. The patients were followed up for a minimum of 1 year. There were no significant differences in gender, age, body mass index (BMI), preoperative hemoglobin level, preoperative Harris hip score (HHS), and preoperative visual analogue scale (VAS) score between the two groups (P > 0.05 for all).ResultsThe incision length, operation time, intraoperative blood loss, blood transfusion volume, and the length of stay (LOS) were significantly less in group A than in group B (p < 0.05). The surgery-related complications were not significantly lower in group A (5.43%) than in group B (10.47%) (χ2 = 2.209, p = 0.112). In 46 cases in group A, one hip had an acetabular anteversion higher than normal value. In both groups, one hip developed aseptic loosening. The HHS was significantly higher in group A than in group B 1, 3, 12 month(s) after operation (p < 0.05). The VAS was significantly lower in group A than in group B 1, 3, 12 month(s) after operation. Against the simple Likert scale, comprehensive satisfaction was significantly higher in group A (97.8%, 45/46) than in group B (76.7%, 33/43) (χ2 = 9.119, p = 0.003).ConclusionIn patients who underwent simultaneous bilateral THA, DAA could significantly relieve pain, accelerate the functional recovery of hip joint and improve the satisfaction more than PA. In clinical practice, however, more attention should be paid to strict compliance to operative indications and the prevention of early complications. The long-term effectiveness warrants further observation.

A Comparison between the Outcomes of Direct Anterior and Posterior Approaches for Rates of Dislocation and Infection in Primary Total Hip Arthroplasty

Background: Direct anterior hip replacement is a slightly aggressive surgical procedure but potentially widespread. It involves opening on the front of the hip to allow the joint to be substituted by moving muscles aside along their ordinary tissue planes without removing any tendons. Nevertheless, there is diminutive consent concerning the threats and profits of this method compared to the posterior approach (PA) regarding the rates of dislocation and infection. Methods: This research is a prospective study conducted in Erbil city from September 2015 to September 2017 on 57 patients, including 28 females and 29 males, with primary total hip arthroplasty (THA). Twenty-nine patients were enrolled in the direct anterior approach (DAA: First group), and 28 patients were registered in the PA group (PA: Second group). Their age ranged between 49 and 80 years, and the regular follow-up was 12 months for all patients. Results: It was found that using the DAA, there was a significantly (P ≤ 0.05) lower incidence rate of dislocation in patients undergoing THA than the PA. No significant difference in the rates of infection was noticed between both groups. However, slightly shorter operational time and extent of the incision were noticed in the DAA group, and less blood loss was found in the PA group (non-significant). Conclusion: We realized that DAA has a clear advantage over PA regarding the lower incidence in the dislocation risk and without variance in the infection rates.

Comparison Between the Direct Anterior and Posterior Approaches for Total Hip Arthroplasty Performed for Femoral Neck Fracture.

To compare 90-day and 1-year outcomes, including mortality, of femoral neck fracture patients undergoing total hip arthroplasty (THA) by direct anterior approach (DAA) versus posterior approach (PA). Retrospective cohort. Level I Trauma Center. One hundred forty-three consecutive intracapsular femoral neck fractures treated with THA from 2010 to 2018. The minimum follow-up was 12 months, and the average follow-up was 14.6 months (12-72 months). Postoperative outcomes, including discharge ambulation, dislocation, periprosthetic joint infection, revision THA, and mortality at 90 days and 1 year after THA. Of the 143 THA included, 44 (30.7%) were performed by DAA while 99 (69.3%) were performed by PA. In-hospital outcomes were similar between the cohorts. Compared with DAA patients, PA patients were more likely to ambulate without assistance preinjury (88.9% vs. 72.7%, P = 0.025) and be nonambulatory at the time of discharge (27.3% vs. 11.4%, P = 0.049). There were no significant differences in 90-day and 1-year postoperative outcomes between the DAA and PA groups, including dislocation, periprosthetic joint infection, periprosthetic fracture, mechanical complications, and revision surgery. Although there was no difference in mortality rate at 90 days, at 1-year follow-up the mortality rate was lower in the DAA group (0% vs. 11.1%, P = 0.018). Performing THA by DAA provides similar benefits in regards to medical and surgical outcomes compared with the PA for displaced femoral neck fracture. However, the DAA may lead to decreased 1-year mortality rates, possibly, because of improved early ambulation capacity that is an important predictor of long-term mortality. Therapeutic Level III.

Comparison of anterior and posterior approaches for treatment of traumatic cervical dislocation combined with spinal cord injury: Minimum 10-year follow-up

Anterior reduction and interbody fusion fixation has not been compared directly with posterior reduction and short-segmental pedicle screw fixation for lower cervical dislocation, and so consensus is lacking as to which is the optimal method. The purpose of this paper is to compare long-term outcomes of the anterior versus posterior approach for traumatic cervical dislocation with spinal cord injury. One hundred and fifty-nine patients could be followed for more than 10 years (follow-up rate 84.1%). Ninety-two patients underwent anterior reduction and interbody fusion and fixation, and 67 patients underwent posterior reduction and short-segmental pedicle screw fixation. Japanese Orthopaedic Association (JOA) scores, the Neck Disability Index (NDI), the American Spinal Injury Association grading (ASIA), Odom’s criteria, cervical kyphosis, operative parameters, and surgical or post-operative complications were evaluated. Patients were followed for 10 to 17 years. There was no significant difference in main JOA scores, NDI scores or ASIA scores between the two groups at follow-up. The posterior approach was associated with greater loss of alignment by two years (P = 0.012) and at final follow-up (P < 0.001). The posterior approach group had more blood loss (P < 0.001), longer operation times (P < 0.001), longer hospital stays (P < 0.001) and fewer complications than the anterior approach group. The anterior approach is better than the posterior approach for preserving cervical lordosis, which is associated with a better long-term effect.

Long-term effectiveness of "West China Classification" guided surgical treatment of desmoid-type fibromatosis in shoulder girdle

To evaluate the long-term effectiveness of patients received surgical treatment under the guidance of "West China Classification" of desmoid-type fibromatosis (DTF) in the shoulder girdle. The clinical data of 32 patients with DTF in the shoulder girdle admitted between June 2003 and December 2016 were retrospectively analyzed, including 14 males and 18 females, aged 14-56 years with an average age of 36.8 years. The maximum diameter of the tumor was 7-19 cm, with an average of 11.1 cm. According to the "West China Classification" of DTF in the shoulder girdle, there were 4 cases of region Ⅰ, 3 cases of region Ⅱ, 6 cases of region Ⅲ, 3 cases of region Ⅳ, 5 cases of regions Ⅰ+Ⅱ, 5 cases of regions Ⅱ+Ⅲ, and 6 cases of regions Ⅰ+Ⅱ+Ⅲ. In addition, the involvement of blood vessels and nerves was also taken into consideration for choosing a surgical approach. Finally, 12 cases were operated via anteroposterior approach (group A), 14 via posterior approach (group B), and 6 via combined anterior-posterior approach (group C). The 1993 Musculoskeletal Tumor Society (MSTS93) score (including pain, limb function, satisfaction, hand position, hand flexibility, and lifting ability), Japanese Orthopedic Association (JOA) score, range of motion (ROM) of shoulder joint (including flexion, extension, abduction, and adduction), and complications of patients in the 3 groups were recorded and compared. All the 32 patients were followed up 30-190 months, with an average of 94.6 months. At last follow-up, complications occurred in 5 cases (15.6%), including 2 cases (16.6%) in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. There was no significant difference in the incidence of complications among the 3 groups ( P=1.000). Tumor recurrence occurred in 5 (15.6%) cases, including 1 (8.3%) case in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. No significant difference was found in the recurrence rate among the 3 groups ( P=1.000). At last follow-up, MSTS93 score of pain, limb function, satisfaction, hand flexibility, and hand position in groups A and B were significantly better than those in group C ( P<0.05), even though no significant difference existed between group A and group B ( P>0.05). The lifting ability score in group C was significantly lower than in group A ( P<0.05), and no significant difference was found between other groups ( P>0.05). The JOA score and flexion, extension, abduction, and adduction activities of shoulder in groups A and B were significantly better than those in group C ( P<0.05). The extension activity in group A was significantly better than that in group B ( P<0.05), the flexion activity in group B was significantly better than that in group A ( P<0.05). There was no significant difference in other indexes between groups A and B ( P>0.05). Taking a rational approach to fully expose and completely remove the tumor is the key point of surgical treatment for patients with DTF in the shoulder girdle. At the same time, preservation of vital structures and reconstruction of soft tissues should also be taken into consideration. Overall, surgical treatment under the guidance of "West China Classification" of DTF in the shoulder girdle has achieved satisfactory long-term effectiveness.

Anterior versus Posterior Scoring of Cartilage in Otoplasty: A Retrospective Patient-related Outcome Measurement Study.

Background:Various surgical techniques are applied to correct prominent ears. However, there are limited data on the effect of otoplasty on patient-related outcome measures, such as cold ears and cold intolerance. This retrospective cohort study describes the occurrence of cold intolerance in 98 patients, with a total of 196 ears in a single center during 6 years (2011–2017).Methods:In this study, 3 groups were identified: group I, anterior scoring of the cartilage (ie, Chong Chet); group II, posterior scoring of the cartilage and suture reposition of the cartilage; and group III, posterior approach without scoring (ie, Furnas and Mustardé). Parents of patients filled in a questionnaire with 40 questions to criticize the effect of surgery.Results:Symptoms of cold intolerance and pain were reported in 44.4% (n = 16) in the anterior scoring group, 48.1% (n = 26) in the posterior scoring group, and 62.5% (n = 5) in the posterior approach group without scoring of the cartilage (P = 0.68). The satisfaction rate was significantly lower in the posterior group without scoring (Likert scale of 17.44 ± 22.01 anterior scoring, 16.02 ± 18.13 posterior scoring, and 11.13 ± 25.87 posterior approach without scoring; P = 0.02).Conclusions:This study underscores the fact that a great part of patients after otoplasty report symptoms of cold intolerance; however, these most often resolve and did not differ between different groups. Patients should be informed about this sequela. Furthermore, overall satisfaction rate was significantly lower in the posterior group without scoring.

The safety and efficacy of anterior versus posterior decompression surgery in degenerative cervical myelopathy: a prospective randomized trial.

The safety and efficacy of anterior and posterior decompression surgery in degenerative cervical myelopathy (DCM) have not been validated in any prospective randomized trial. In this first prospective randomized trial, the patients who had symptoms or signs of DCM were randomly assigned to undergo either anterior cervical discectomy and fusion or posterior laminectomy with or without fusion. The primary outcome measures were the change in the visual analog scale (VAS) score, Neck Disability Index (NDI), and Nurick myelopathy grade 1 year after surgery. The secondary outcome measures were intraoperative and postoperative complications, hospital stay, and Odom's criteria. The follow-up period was at least 1 year. A total of 68 patients (mean age 53 ± 8.3 years, 72.3% men) underwent prospective randomization. There was a significantly better outcome in the NDI and VAS scores in the anterior group at 1 year (p < 0.05). Nurick myelopathy grading showed nonsignificant improvement using the posterior approach group (p = 0.79). The mean operative duration was significantly longer in the anterior group (p < 0.001). No significant difference in postoperative complications was found, except postoperative dysphagia was significantly higher in the anterior group (p < 0.05). There was no significant difference in postoperative patient satisfaction (Odom's criteria) (p = 0.52). The mean hospital stay was significantly longer in the posterior group (p < 0.001). Among patients with multilevel DCM, the anterior approach was significantly better regarding postoperative pain, NDI, and hospital stay, while the posterior approach was significantly better in terms of postoperative dysphagia and operative duration.

Impact of the Surgical Approach: A Comparative Study between Transcanal and Posterior Tympanotomy Approach for Cochlear Implantation

Abstract Introduction The aim of our study is to compare the surgical complications of the transcanal and posterior tympanotomy approach and to evaluate the advantages and disadvantages of both techniques. Materials and Methods It is a prospective study involving 252 pediatric cochlear implant patients operated in the Department of ENT, GMERS Medical College and General Hospital, Gandhinagar, Gujarat, India. Out of these, 126 patients were operated by transcanal approach (group A) and 126 patients were operated by posterior tympanotomy approach (group B). Results No significant difference in the mean duration of surgery (p &gt; 0.064) was observed in both the groups. Major complications occurred in 60.2% of group A and 3.1% of group B and minor complications occurred in 65% of group A and 3.1% in group B, which is highly significant (p &lt; 0.0134). The categories of auditory perception, speech intelligibility rating scales, meaningful auditory integration scale, and meaningful use of speech scale were assessed in both groups. Conclusion Complication rate in the transcanal approach is higher as compared with posterior tympanotomy approach. A complete alignment and introduction of electrode array into the basal turn of cochlea is more favorable in the posterior tympanotomy approach. Transcanal technique even as an alternative may not be useful. Outcomes may be affected depending upon the technique chosen.

Sagittal spinopelvic alignment after spinal fusion in degenerative lumbar scoliosis: a meta-analysis

Objective: This meta-analysis aimed to investigate the changes in sagittal spinopelvic alignment in degenerative lumbar scoliosis (DLS) from the preoperative state to the last follow-up.Methods: The MEDLINE via PubMed, Cochrane, Scopus, and Embase databases were searched for studies published between January 2010 and January 2019 evaluating radiological parameters including the coronal Cobb angle, sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) in DLS. Two authors performed data extraction independently. All discrepancies were resolved by consensus.Results: The 34 studies identified showed significant decreases in overall and subgroup Cobb angles from the preoperative state to the last follow-up. Both overall TK and LL were significantly increased from the preoperative state to the last follow-up. In subgroup analysis, LLs in the long fusion, combined approach, and posterior approach group were significantly increased at the final follow-up, but the LL increase in the short fusion group was not significant at the last follow-up. However, there was no significant change in SVA, PI, SS, and PT from the preoperative state to the last follow-up.Conclusions: A literature review identified 34 studies reporting preoperative and last follow-up data on spinal fusion in DLS. Despite heterogeneity, a limited meta-analysis showed significant improvement in the coronal Cobb angle, TK, and LL after spinal fusion in DLS. A large, randomized clinical trial would be necessary to validate our results.

Anterior-Approach Versus Posterior-Approach Levator Advancement Surgery in Aponeurotic Ptosis.

To compare the effectiveness and complications of levator reinsertion in aponeurotic ptosis surgery using anterior and posterior approaches. Seventy-eight (36 females, 42 males) patients with acquired aponeurotic ptosis were evaluated. Pre- and postoperative margin reflex distance, symmetry of height, contour and skin crease, corneal problems, and lagophthalmus were evaluated and compared between the 2 groups. Independent and paired samples t-test, Pearson Chi-square, and Fisher exact test were used to evaluate the results. The anterior approach was performed on 43 eyelids and the posterior approach was performed on 35 eyelids. The mean age of the anterior-approach group was 62.1 ± 11 years, and posterior-approach group was 50.1 ± 15.1 years, respectively (P < 0.001). The male-female ratio was 28/15 in the anterior-approach group, and 14/21 in the posterior approach group (P = 0.027). The success rate of the anterior approach was 69.8% and the posterior approach was 57.1% (P = 0.248). The mean margin reflex distance change was statistically significant in both anterior- and posterior-approach techniques (P < 0.001, P < 0.001, respectively). Three (6.9%) patients in the anterior-approach group and 11 (31.4%) in the posterior-approach group required reoperation (P = 0.005). Lagophthalmus rates were similar (3 eyes in the anterior versus 7 eyes in the posterior group, P = 0.103). Both anterior- and posterior-approaches are effective and safe techniques for aponeurotic ptosis treatment. The posterior approach seems to be preferred by female and younger patients because there is no undesirable scar formation although it has the disadvantage of higher rates of reoperation.

Posterior versus direct anterior approach in revision hip arthroplasty using Kerboull-type plate.

Introduction: The purpose of this study was to investigate revision with a Kerboull-type plate through the posterior approach (PA) and direct anterior approach (DAA) and compare the clinical outcome.Subjects and methods: Fifty-four patients (56 hip joints) underwent revision surgery in which acetabular reconstruction was performed concomitantly using the Kerboull-type plate and allogeneic bone. Revision surgery through DAA was performed in 21 hip joints and these were compared with 34 hip joints treated through PA. There was no significant difference in the patient demographics between the DAA and PA.Results: There was no significant difference between the operative times in the DAA and PA groups (203.2 ± 43.5 and 211.7 ± 41.8 min). There was a significant difference between the intraoperative blood loss in the DAA and PA groups (503.9 ± 223.7 mL and 703.8 ± 329.6 mL, respectively, p < 0.05). There was no significant difference between the modified Harris Hip Score in the DAA and the PA groups. The loosening of the acetabular component was observed in four cases (11.8%) in the PA group. In the DAA and PA groups, the 5-year survival rates were 100 and 85.7%, respectively. Recurrent dislocation of the hip was observed in six cases (one case in the DAA group (4.8%) and five cases in the PA group (14.7%)).Conclusions: It was verified that the difference in the surgical approach of acetabular reconstruction concomitantly using the Kerboull-type plate and allogeneic bone graft influenced the postoperative outcome.

Kyphotic deformity correction of different operative approaches in patients with thoracolumbar burst fractures: a meta-analysis

Background: As a common traumatic disease in spine surgery, thoracolumbar burst fractures (TLBF) often leads to complications such as back pain, kyphotic deformity and nerve damage, causing severe physical defects and economic burden on patients. Objective: To explore kyphotic deformity correction of different operative approaches for TLBF. Design of research: Systematic review and meta-analysis are utilized to compare the efficacy of different approaches for postoperative kyphotic deformity in TLBF patients. Methods: English documents that discussed TLBF with different operative approaches were searched from various databases. The obtained documents were screened and evaluated. Results: The comparison and analysis of preoperative Cobb angle, early-postoperative Cobb angle correction, and follow-up Cobb angle correction between the anterior and posterior approach groups showed no statistical significance [MD=0.97, 95% CI (-0.44, 2.38), P=0.18; MD=0.25, 95% CI (-0.04, 0.54), P=0.10; MD=-0.12, 95% CI (-0.44, 0.19), P=0.45]. Conclusion: While treating TLBF symptoms, both the anterior and posterior approaches were effective in correcting postoperative kyphosis deformity. Therefore, while determining a treatment method, the age and the tolerance to the surgery of each patient should be considered for the surgical treatment options. This study provides new ideas for clinical treatment of TLBF in the future.
