Abstract Background To assess the impaction of reconstruction accuracy of hip center of rotation (COR) on midterm clinical and radiographic results of cementless reconstruction of total hip arthroplasties (THAs) for patients after failed treatment of acetabular fractures. Methods One hundred and four patients (107 hips) who underwent THAs after failed treatment of acetabular fractures were retrospectively evaluated and cementless cups and stems were implanted in all hips. Clinical outcomes were assessed using the Harris hip score (HHS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scoring system. Radiographic results were analyzed by serial perioperative x-rays. Results At the latest follow-up examination, the median HHS increased from 52 (42-65) before surgery to 93 (90-97) (p < 0.001) and the median WOMAC decreased from 52 (36-65) before surgery to 5.8 (1.5-8) (p < 0.001). Compared with normal contralateral hip, 79 cups migrated superiorly (0.2-33.6mm) and 22 cups migrated inferiorly (0.2-16.1mm). The distance of superior migration of reconstructed COR was correlated with positive Trendelenburg sign at the latest follow-up examination (r=0.504; p < 0.001). The percentage of postoperative Trendelenburg sign was significantly higher in superior migration subgroup than that in subgroup with anatomical restoration of COR (P=0.015). Conclusions Cementless THAs in patients after failed treatment for acetabular fractures achieved predictable clinical and radiographic outcomes. A superiorly migrated hip COR appeared to exert a negative effect on abductor muscle function.

Abstract Background The purpose of this study was to review retrospectively the primary total hip arthroplasties operated upon with the cementless Wagner Self-Locking stem in patients with type C femoral bone. Methods Twenty-eight total hip arthroplasties were performed in 25 patients aged ≥ 60 years using a cementless Wagner Self-Locking femoral component between 2006 and 2011. According to Dorr’s criteria, all 28 femora were classified as type C bone. All patients were treated with THA using a cementless Wagner cone prosthesis. Clinical and radiologic evaluations were performed on all patients. Results Mean follow-up period was 125 ± 10.5 months (range 96 to 156 months). Average Harris hip score pre-operatively was 46 ± 9 (range 39 to 62) and at the last follow-up was 90 ± 9 (range 83 to 98). The stem to canal fill is calculated as percentages on the operative side at three distinct levels: just below the lesser trochanter, at midstem, and 1 cm above the tip of the component on anteroposterior radiograph. The mean proximal stem-to-canal fill percentages were 97% ± 2.1%, 95% ± 3.5%, and 88% ± 2.6%, respectively (anteroposterior view) and 92% ± 2.2%, 86% ± 1.9%, and 83% ± 2.5%, respectively (lateral view). Radiographic evaluation demonstrated good osteointegration of the implants in the follow-up. Conclusions Based on the long-straight cylindrical tapered stem design, the cementless Wagner SL stem can achieve reliable stability by close apposition of the stem and wide stovepipe femoral canal from metaphysis to diaphysis in type C bone.

Abstract Background: To evaluate the clinical features and results of the revision total hip arthroplasties (THA) in patients with catastrophic failures and metallosis. Methods: Fifteen hips of 14 patients with catastrophic failure and metallosis in hip arthroplasties were evaluated. They were followed for at least 4.2 years after the revision THA. Clinical evaluation was performed using Harris hip score. Osteolysis, loosening or presence of metallosis was evaluated with standard radiographs. Metallosis was evaluated intraoperatively according to the metallosis severity classification. Results: The mean time from failure until revision surgery was 9.4 years. It was observed that in the primary THA, metal-on-ceramic (MoC), ceramic-on-ceramic (CoC) and metal-on-conventional polyethylene (MoCPE) bearings were used in 1, 3 and 11 hips, respectively. Grade III metallosis was observed in all patients during revision surgeries. The mean Harris hip score increased from 55 points before revision THA to 75 points at the final follow-up. In revision arthroplasty, MoCPE and CoC bearings were used in 13 and 2 hips, respectively. The femoral stem was replaced in 5 hips. All acetabular cups, except that of one hip, were revised. Conclusions: Revisions of THAs with catastrophic failures and metallosis are quite challenging. Routine follow-up of arthroplasty patients is beneficial to examine for osteolysis, loosening, and asymmetric wear.

Abstract Background The aim of the present study was to investigate clinical and radiological outcomes of autologous tricortical iliac graft through a window created at the femoral head, without suturing the opened articular cartilage to treat osteonecrosis of the femoral head (ONFH), called modified trapdoor procedures. Methods A total of 59 consecutive patients (67 hips ) with ONFH were included in this study, which was conducted during the period from April 2009 to March 2012. Harris hip scores (HHS) were used to evaluate hip function pre- and postoperatively. Anteroposterior and frog-position X-rays and magnetic resonance imaging (MRI) were conducted to evaluate lesion location, size, and ARCO stage. Clinical failure was defined as score < 80 points or treatment by total hip arthroplasty(THA). Radiographic failure was defined as a > 3 mm of collapse in the hip. This group was retrospectively matched according to the ARCO stage, extent, location, etiology of the lesion, average age, gender, and preoperative Harris hip score to a group of 59 patients (67 hips) who underwent the“light bulb”approach during March 2007 to April 2009. Results Mean follow-up was 91.2 ± 13.6 months (range, 75–115 months). Mean HHS was 91.3 ± 4.5, compared with 83.1± 4.5 in the “light bulb” cohort at the 6 years follow-up examination ( P < 0.001). At the 6 years follow-up, for modified trapdoor procedures, five hips (8.5%) were classified as clinical failure, and 3 hips underwent total hip arthroplasty; Seven hips were classified as (10.4%) radiographic failure.The clinical and radiographic failure of the hips treated with the modified trapdoor procedure was significantly lower than that of the hips treated with the “light bulb” procedure (p < 0.05). Survival of the joint was not significantly related to the location of the femoral head lesion between two groups, but there was better clinical and radiographic results in modified trapdoor procedures with Size-C and the ARCO stage III. Conclusion The study demonstrated superior medterm clinical results in ONFH with the use of autologous tricortical iliac block graft through a femoral head window, without suturing the opened articular cartilage.

Purpose: the purpose of the present paper is to present the short-term results of a “detachment-free” (DF) anterolateral approach for primary total hip replacement (THR) performed in a large series of patients. Methods: two hundred patients submitted to primary THR were retrospectively reviewed for the present study. In all cases, the surgery was performed using a minimally invasive DF anterolateral approach, which entails no disconnection of tendons and no muscle damage. The study population consisted of 96 men (48%) and 104 women (52%), with an average age of 69.4 years (range 38-75). Clinical and radiographic follow-up was performed after 12 months. Results: the clinical results, evaluated using the Harris Hip Score, were excellent in 95% of the cases and good in 5%; no cases had fair or poor results. X-rays taken at 3, 6 and 12 months after surgery did not show heterotopic ossification, mobilization of the prosthetic components, or hip dislocation. No infections, deep vein thrombosis, or failure of the gluteal muscles were reported. Conclusions: the DF anterolateral approach for THR proved safe and provided effective results at shortterm follow-up. Level of evidence: Level IV, therapeutic case series.

Purpose: Total hip arthroplasty (THA) is an available surgical option for failed acetabular fracture, previously managed by open reduction and internal fixation. This study aimed to report the postoperative outcomes of cementless THA in patients with this condition. Materials and Methods: Between November 2000 and September 2016, 25 consecutive cementless THAs for failed internal fixation after acetabular fractures with a minimum follow-up of 2 years were analyzed. The mean age at the time of surgery was 58 years (36–85 years), and the time elapsed between fracture and THA was 70 months (7–213 months). Clinical and radiologic evaluations were performed on all patients. Results: Clinically, the mean Harris hip score at the last follow-up was 88 points. Walking ability recovered to pre-injury status in 92% patients, and activities of daily living recovered in 96% patients. Radiographically, none of the acetabular cups showed evidence of migration and loosening during the mean follow-up of 50 months. All cases showed stable femoral stem fixation at the last follow-up. Dislocation occurred in three cases (12%). Conclusion: Outcomes of cementless THA after failed internal fixation for acetabular fractures were satisfactory. However, a relatively high incidence of postoperative dislocation is still a concern.

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.

The purpose of this study was to review retrospectively the primary total hip arthroplasties operated upon with the cementless Wagner self-locking stem in patients with Type C femoral bone. Twenty-five total hip arthroplasties were performed in 23 patients aged ≥60 years using a cementless Wagner self-locking femoral component between 2006 and 2011. According to Dorr's criteria, all 25 femora were classified as type C bone. Mean follow-up period was 62 months (range, 47–85 months). Average Harris Hip score preoperatively was 46 ± 9 (range, 39–62) and at the last follow-up was 90 ± 9 (range, 83–98). The mean proximal stem-to-canal fill percentage was 95% ± 3.5% (anteroposterior view) and 90% ± 2.8% (lateral view) and the mean distal canal fill was 93% ± 4.5% (anteroposterior) and 92% ± 3.9% (lateral). Radiographic evaluation demonstrated good osteointegration of the implants in follow-up. Based on the long-straight cylindrical tapered stem design, the cementless Wagner SL stem can achieve reliable stability by close apposition of stem and wide stovepipe femoral canal from metaphysis to diaphysis in Type C bone.

A Prospective Study

Neglected acetabular fractures are often challenging to treat. The aim of this study is to highlight the technique of acetabular distraction with porous metal cup as a viable technique to address such complex cases. This is a prospective study of seven patients who had neglected acetabular fracture or fracture non-union that were managed with total hip arthroplasty using acetabular distraction and porous metal cup with cemented liner. The average age of the patients was 51 years (range 36-58 years). Average time of follow up was 18 months (range 12-36 months). Radiological results at latest follow up and by comparing serial radiographs showed that all cases had a well-fixed implant construct without evidence of loosening or malorientation. Average Harris hip score pre-operatively was 46, which improved to an average of 84 post-operatively. Our study shows that total hip replacement using acetabular distraction with porous metal cup provide early good results in reconstruction of acetabular bony deficiencies due to neglected acetabular fracture.
