Objectives: The aim of this study is to review the short-term results of total hip arthroplasty (THA) for the management of delayed arthritis after acetabular fractures. Methods: This is a retrospective study of operated cases of THA post-acetabular fracture arthritis. Data were collected from computerized hospital records from January 2010 to December 2019. We analyzed post-operative outcomes, which included revision surgery due to any reason, post-operative infection, hip dislocation, sciatic nerve injury, and deep venous thrombosis. In addition, radiographs were evaluated for restoration of the center of rotation (COR), horizontal offset (HO), and vertical offset (VO) by an independent observer. Results: A total of 36 cases (30 males and six females) were included in the study. The average age was 55 years. Road traffic accidents were the most common cause of fractures followed by falls from height. The mean time between the fracture and the development of symptoms of arthritis was 48 months. One THA was complicated by post-operative dislocation. Infection was reported in three cases and sciatic nerve injury occurred in one patient. Heterotopic ossification was seen in four cases and thromboembolism developed in one patient. The COR, HO, and VO showed a normal pattern. Conclusion: THA after acetabular fractures is a complex surgical procedure with relatively high short-term complications. Restoring the hip biomechanics can help in achieving results that are comparable to primary total hip replacement.

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.

OBJECTIVEThe sciatic nerve, particularly its peroneal division, is at risk for injury during total hip arthroplasty (THA), especially when a posterior approach is used. The majority of the morbidity results from the loss of peroneal nerve–innervated muscle function. Approximately one-third of patients recover spontaneously. The objectives of this study were to report the outcomes of distal decompression of the peroneal nerve at the fibular tunnel following sciatic nerve injury secondary to THA and to attempt to identify predictors of a positive surgical outcome.METHODSA retrospective study of all patients who underwent peroneal decompression for the indication of sciatic nerve injury following THA at the Mayo Clinic or Washington University School of Medicine in St. Louis was performed. Patients with less than 6 months of postoperative follow-up were excluded. The primary outcome was dorsiflexion strength at latest follow-up. Univariate and multivariate logistic regression analyses were performed to assess the ability of the independent variables to predict a good surgical outcome.RESULTSThe total included cohort consisted of 37 patients. The median preoperative dorsiflexion grade at the time of peroneal decompression was 0. Dorsiflexion at latest follow-up was Medical Research Council (MRC) ≥ 3 for 24 (65%) patients. Dorsiflexion recovered to MRC ≥ 4− for 15 (41%) patients. In multivariate logistic regression analysis, motor unit potentials in the tibialis anterior (OR 19.84, 95% CI 2.44–364.05; p = 0.004) and in the peroneus longus (OR 8.68, 95% CI 1.05–135.53; p = 0.04) on preoperative electromyography were significant predictors of a good surgical outcome.CONCLUSIONSAfter performing peroneal nerve decompression at the fibular tunnel, 65% of the patients in this study recovered dorsiflexion strength of MRC ≥ 3 at latest follow-up, potentially representing a significant improvement over the natural history.

Abstract Introduction: Acetabular fractures (AFxs) are rare injuries considering their incidence. The gold standard of treatment is open reduction and internal fixation (ORIF). Surgical treatment represents a challenge for orthopedic surgeons. Our purpose is to assess the short- to medium-term functional outcomes and complications of surgically treated AFx. We analysed the factors influencing clinical outcomes, the incidence of complications and the predictors of conversion in total hip arthroplasty (THA).Materials and Methods: We retrospectively analysed 102 patients with AFx treated between December 2017 and September 2020. The inclusion criteria were AFx treated with ORIF and more than 12 months of follow-up (FU). We evaluated the quality of reduction with X-ray measuring residual displacement, classified into 3 groups (Matta Radiological Score). Postoperative superficial and deep infections, neurological sequelae and deep vein thrombosis were documented. X-rays were performed to confirm the adequacy of fixation and complications. At the final FU, the radiographs were graded according to Matta’s Radiological Outcome Grading, and the clinical outcomes were graded using the Oxford Hip Score (OHS).Results: Of 102 patients, 62 patients were enrolled. The statistical analysis revealed that OHS was influenced by quality of reduction (P=0.033), injury severity score (ISS) (P=0.005) and age (> 75 years) (P=0.029). A significant correlation between the patient’s BMI and the OHS was recorded. The late sequelae were heterotopic ossification (HO) in 13 patients, osteoarthritis (OA) in 22 and avascular necrosis (AVN) in 4. HO was significantly affected by the posterior approach (P=0.031) and by an ISS > 15 (P= 0.0003). The analysis showed a correlation between AVN and posterior hip dislocation (P=0.004). OA had a correlation with postoperative quality of reduction (P=0.014). Eight patients required THA. Comparing patients with and without THA, a significant correlation between THA and posterior dislocation (P=0.022), isolated posterior wall fracture (P=0.039) and ISS > 15 (P=0.029) was recorded.Conclusion: Despite the improvement of surgical techniques and perioperative care, a high rate of patients with AFx still develop complications and require THA. Identifying negative predictors to help the management of fractures in elderly individuals is needed. Furthermore, the presence of negative predictors could represent an indication for primary THA.

Acetabulum Fracture

Background: Acetabular fractures are complex orthopaedic injuries and require a fair amount of expertise for management. Although undisplaced acetabular fractures can be managed by nonoperative means, displaced acetabular fractures need operative intervention for reduction and stabilization. Methods: The study was carried as a retrospective study, from February 2013 to July 2014. After getting the approval from the Ethics Committee of the Institute (Annexure I) and the consent from the patients the study was conducted on 49 patients who underwent Total Hip Arthroplasty after fracture acetabulum. Results: On evaluation, patients at short term follow up had good clinical outcome on the basis of Harris hip score. The Harris hip scores improved progressively in the patients at 2-4 years follow up having mean HHS of 92 which further increased to 97 in patients who were followed up after 4 years. The patients at short term follow up of up to 2 years had comparatively lower quality of life scores when compared to the follow up at 2-4 years. The patients followed up after 4 years had the best quality of life. Conclusion: We concluded that total hip arthroplasty after acetabulum fracture, as a result of good quality of reconstruction, a good functional outcome leads to improved quality of life in the patients.

Introduction: Sciatic nerve injury (SNI) is a potentially devastating complication after total hip arthroplasty (THA). Intraoperative neural monitoring has been found in several studies to be useful in preventing SNI, but can be difficult to implement. In this study, we examine the results of using a handheld nerve stimulator for intraoperative sciatic nerve (SN) monitoring during complex THA requiring limb lengthening and/or significant manipulation of the SN. Methods: A consecutive series of 11 cases (9 patients, 11 hips) with either severe developmental dysplasia of the hip (Crowe 3-4) or other underlying conditions requiring complex hip reconstruction involving significant leg lengthening and/or nerve manipulation. SN function was monitored intraoperatively by obtaining pre- and post-reduction thresholds during component trialing. The results of nerve stimulation were then used to influence intraoperative decision-making. Results: No permanent postoperative SN complications occurred, with an average increase of 28.5 mm in limb length, range (6-51 mm). In 2 out of 11 cases, a change in nerve response was identified after trial reduction, which resulted in an alternate surgical plan (femoral shortening osteotomy and downsizing femoral head). In the remaining cases, the stimulator demonstrated a response consistent with the baseline assessment, assuring that the appropriate lengthening was achieved without SNI. 1 patient had a transient motor and sensory peroneal nerve palsy, which resolved within 2 weeks. Conclusions: The intraoperative use of a handheld nerve stimulator facilitates surgical decision-making and can potentially prevent SNI. The real-time assessment of nerve function allows immediate corrective action to be taken before nerve injury occurs.

Staged Reconstruction

Abstract Background and purpose Total hip arthroplasty (THA) is a successful approach to treat unilateral symptomatic neglected hip dislocation (NHD). However, the extensive leg length discrepancy (LLD) can hereby only be partially corrected. In case of residual LLD of more than 2 cm, subsequent femoral lengthening can be considered. Patients/material/methods Retrospective analysis of clinical data and radiographs of five patients (age 38.1 (28–51) years) with unilateral NHD who underwent THA with (n  = 3) or without (n = 2) subtrochanteric shortening osteotomy (SSO) and secondary intramedullary femoral lengthening through a retrograde magnetically-driven lengthening nail (follow-up 18.4 (15–27) months). Results LLD was 51.0 (45–60) mm before and 37.0 (30–45) mm after THA. Delayed bone union at one SSO site healed after revision with autologous bone grafting and plate fixation. Subsequent lengthening led to leg length equalisation in all patients. Complete consolidation was documented in all lengthened segments. Conclusion Staged reconstruction via THA and secondary femoral lengthening can successfully be used to reconstruct the hip joint and equalise LLD. The specific anatomical conditions have to be taken into consideration when planning treatment, and patients ought to be closely monitored.
