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 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.

Aims Femoral bone preparation using compaction technique has been shown to preserve bone and improve implant fixation in animal models. No long-term clinical outcomes are available. There are no significant long-term differences between compaction and broaching techniques for primary total hip arthroplasty (THA) in terms of migration, clinical, and radiological outcomes. Methods A total of 28 patients received one-stage bilateral primary THA with cementless femoral stems (56 hips). They were randomized to compaction on one femur and broaching on the contralateral femur. Overall, 13 patients were lost to the ten-year follow-up leaving 30 hips to be evaluated in terms of stem migration (using radiostereometry), radiological changes, Harris Hip Score, Oxford Hip Score, and complications. Results Over a mean follow-up period of 10.6 years, the mean stem subsidence was similar between groups, with a mean of -1.20 mm (95% confidence interval (CI) -2.28 to -0.12) in the broaching group and a mean of -0.73 mm (95% CI -1.65 to 0.20) in the compaction group (p = 0.07). The long-term migration patterns of all stems were similar. The clinical and radiological outcomes were similar between groups. There were two intraoperative fractures in the compaction group that were fixed with cable wire and healed without complications. No stems were revised. Conclusion Similar stem subsidence and radiological and clinical outcomes were identified after the use of compaction and broaching techniques of the femur at long-term follow-up. Only the compaction group had intraoperative periprosthetic femur fractures, but there were no long-term consequences of these. Cite this article: Bone Jt Open 2021;2(12):1035–1042.

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.

Internal fixation is commonly used to treat fractures in the hip. However, failure of proximal femoral fracture fixation is common and treated with total hip replacement (THR). The aim of this study is to present our midterm results of dual mobility (DM) THR for failed internal fixation of proximal femur fractures. Between 2010 and 2015, a total of 28 cases of failed internal fixation for hip fractures were treated through DM total hip arthroplasty. Two patients died during the early postoperative period due to medical complications. The average follow-up was 3.4 years. We had one patient with superficial surgical site infection which was managed by local wound debridement and dressings. The average Harris hip score was 85. DM THR is the procedure of choice for revising failed internal fixation for hip fractures in our patients with good clinical outcome.

AimsStudying the indications for revision total hip arthroplasty (THA) may enable surgeons to change their practice during the initial procedure, thereby reducing the need for revision surgery. The aim of this study was to identify and describe the potentially avoidable indications for revision THA within five years of the initial procedure.Patients and MethodsA retrospective review of 117 patients (73 women, 44 men; mean age 61.5 years (27 to 88)) who met the inclusion criteria was conducted. Three adult reconstruction surgeons independently reviewed the radiographs and medical records, and they classified the revision THAs into two categories: potentially avoidable and unavoidable. Baseline demographics, perioperative details, and quality outcomes up to the last follow-up were recorded.ResultsA total of 60 revision THAs (51.3%) were deemed potentially avoidable and 57 (48.7%) were deemed unavoidable. The following were identified as avoidable factors: suboptimal positioning of the acetabular component (29; 48%), intraoperative fracture or a fracture missed on an intraoperative radiograph (20; 33%), early (less than two weeks) aseptic loosening (seven; 11.7%), and symptomatic leg length discrepancy of > 1 cm (four; 6.7%).ConclusionA surprisingly large proportion of acute revision THAs are potentially avoidable. Surgeons must carefully evaluate the indications for revision THAs in their practice and identify new methods to address these issues. Cite this article: Bone Joint J 2019;101-B(6 Supple B):97–103.

Introduction: Since dislocation after total hip arthroplasty (THA) greatly diminishes patient’s quality of life, the THA frequently needs revision. However, it is common for the dislocation not to heal even after reconstruction, but rather to become intractable. Methods: The 17 patients with dislocated THA, mean age of 71 years (range 51-87 years), who underwent a revision THA together with soft tissue reinforcement with a Leeds-Keio (LK) ligament were enrolled. The purposes of reinforcement with LK ligament were to restrict the internal rotation of the hip joint, and to encourage the formation of fibrous tissue in the posterior acetabular wall to stabilise the femoral head. We determined the success rate of surgical treatment for dislocation, the Harris Hip Score (HHS), a factor of recurrent dislocation. Results: There was no recurrent dislocation in 82% of the cases (14 joints) during the mean postoperative follow-up period of 63.5 months (15-96 months). The HHS was 82 ± 18 points preoperatively and 82 ± 14 points postoperatively. Recurrent dislocation after this surgical procedure occurred in 2 hips with breakage of the LK ligaments, and intracapsular dislocation in 1 hip with loosening of the LK ligament. Conclusions: Although the risk of recurrent dislocation still exists with this procedure, when performed to provide reinforcement with an LK ligament for dislocated THA it may be useful in intractable cases with soft tissue defects around the hip joint.

The authors present the results of 57 revisions in 54 patients performed for aseptic loosening of cemented total hip arthroplasties. The Charnley technique and implants were used in all cases. The mean follow-up was 8 years and 6 months with a minimum of 5 years. The failure rate for the femoral component was 15% and for the acetabular component it was 19.1%. The cumulative success rate at 8 years was 81.7% for the femoral component and 83.4% for the acetabular component. The Charnley technique and implants were found efficient for revision of cemented total hip arthroplasties in the long term, but there are limitations to their use in the presence of severely compromised bone stock.
