Purpose To review the outcome of acetabular revision with bone grafting and cementation for aseptic loosening after primary Charnley low-friction hip arthroplasty with structural bulk autografts in 15 patients. Methods Records were reviewed for 3 men and 12 women aged 31 to 72 (mean, 53) years who underwent acetabular revision with bone grafting and cementation for aseptic loosening at a mean of 12.4 (range, 6.6–20.3) years after primary Charnley low-friction hip arthroplasty with superolateral structural bulk autografts from the femoral head for dysplastic hip (n=14) or bone loss secondary to acetabular fracture (n=1). Results After a mean follow-up of 6.7 (range, 1.1–14.5) years, the mean Merle d'Aubigné and Postel score improved from 8.55 to 16.5. Bridging trabeculae was noted in 10 hips and graft remodelling in 5 hips. Five hips had ectopic ossification of Brooker grade 1 to 2. The mean hip centre of rotation was 21.6 (range, 16.2–30.6) mm. Two women required re-revision for aseptic loosening of the acetabulum after 8.5 and 6.6 years. The first one underwent re-revision with solid allograft for superolateral deficiency of the acetabulum. The second one underwent re-revision with solid and morselised bone allografts for loosened acetabulum. One patient had superior migration of the acetabulum for 9 mm at year 2, but it was asymptomatic. One patient had a dislocation that was reduced with manipulation under anaesthesia. Three patients had trochanteric non-union and presented with lateral thigh pain and tenderness, but no further surgery was performed. Conclusion The medium-term outcome of acetabular revision with bone grafting and cementation is satisfactory. Repeat bone grafting is required to restore the anatomic acetabular position and bone loss secondary to acetabular loosening.

The Mean

Background: Revision total hip arthroplasty (THA) remains a significant challenge when there is severe femoral bone loss. The purpose of this study was to evaluate the clinical and radiographic outcomes of revision THA in patients with femoral bone loss treated with Zweymüller SLR-Plus stem. Methods: A retrospective review of 82 patients who underwent revision THA using tapered rectangular femoral stem between 1997 and 2007 was undertaken. Of the 82 patients, 9 patients were lost to follow-up and were excluded from the study. The most common reason for revision was aseptic loosening (92%), periprosthetic femur fracture (5%), and infection (3%). Bone loss was categorised preoperatively according to the Paprosky classification. The mean clinical follow-up was 14 years (range 10–19 years). Their mean age at the time of index surgery was 54.7 ± 15.3 (range 30–82) years. Results: The mean Harris Hip Score was significantly improved at final follow-up (68.1 ±10.3) compared with that before the revision surgery (30.4 ± 7.7) ( p < 0.0001). Of the 75 stems, 69 (92%) stems were radiographically stable at the last evaluation. Among the 69 stems, 64 hips (85%) had radiographic evidence of bone ingrowth and 5 (5%) had stable fibrous fixation of the stem. Among the 7 hips that were re-revised, 5 hips were re-revised for aseptic loosening, whereas 2 were re-revised for an infection. Kaplan-Meier survivorship analysis, with removal of the stem for any cause as the endpoint, revealed that the 15-year rate of survival of the components was 90% (95% CI, 0.83–0.97). Conclusion: Revision THA in patients with proximal femoral bone loss using Zweymüller SLR-Plus stem led to a high rate of osseointegration of the stem and good clinical results at long-term follow-up.

Purpose To review the outcome of total hip arthroplasty (THA) using a short femoral stem in 33 hips. Methods Records of 33 hips in 20 men and 10 women aged 25 to 40 (mean, 30) years who underwent cementless THA using a short femoral stem by a single senior surgeon were reviewed. The diagnosis included avascular necrosis (n=9), ankylosing spondylitis (n=12), rheumatoid arthritis (n=7), post-traumatic arthritis (n=4), and Hurler syndrome (n=1). Clinical outcome was assessed using the Harris Hip Score. Radiological outcome was assessed according to a modified Gruen zoning system. Stem positioning (neutral, varus, valgus) and bone contact were evaluated, as were fixation and early host response as well as subsidence and changes in the calcar region (zone 5). Trabecular response (trabecular attachment), spot welds, cortical hypertrophy, and pedestal formation were determined. Heterotopic ossification was graded by the Brooker classification. Results The mean follow-up period was 6.5 years. The mean Harris Hip Score improved from 40 to 90. All hips achieved immediate postoperative stability. No patient had thigh pain. Four hips had varus placement (5°–7°) of the stem; all were asymptomatic and remained stable without any migration. Evidence of proximal load transfer (endosteal spot welds) between the endosteum and the stem in zones 2 and/or 4 was noted in 12 hips on both sides and in 8 hips on the lateral side only. At one year, all stems showed evidence of osseointegration. None had subsidence or progressive varus migration. There was no radiolucent line or osteolysis around the stem, pedestal formation or buttressing at the prosthesis tip, or cortical hypertrophy. One patient had grade I heterotopic ossification that was not clinically significant. One patient had a 1.5 cm leg lengthening. One patient had a discharging sinus, a loosened acetabular component, and intrapelvic migration at 2 years and underwent implant removal and debridement. One patient developed a crack in the proximal femur even with the smallest stem. The stem was fixed with cerclage wiring and remained stable with no migration. Conclusion A short femoral stem design that transfers load proximally through a prominent lateral flare achieved good short-term outcome in younger patients. Nonetheless, the ease of removal and preservation of bone at the time of revision should guide the choice of the design of the short stem.

Acetabular Defects

Aims The use of trabecular metal (TM) shells supported by augments has provided good mid-term results after revision total hip arthroplasty (THA) in patients with a bony defect of the acetabulum. The aim of this study was to assess the long-term implant survivorship and radiological and clinical outcomes after acetabular revision using this technique. Patients and Methods Between 2006 and 2010, 60 patients (62 hips) underwent acetabular revision using a combination of a TM shell and augment. A total of 51 patients (53 hips) had complete follow-up at a minimum of seven years and were included in the study. Of these patients, 15 were men (29.4%) and 36 were women (70.6%). Their mean age at the time of revision THA was 64.6 years (28 to 85). Three patients (5.2%) had a Paprosky IIA defect, 13 (24.5%) had a type IIB defect, six (11.3%) had a type IIC defect, 22 (41.5%) had a type IIIA defect, and nine (17%) had a type IIIB defect. Five patients (9.4%) also had pelvic discontinuity. Results The overall survival of the acetabular component at a mean of ten years postoperatively was 92.5%. Three hips (5.6%) required further revision due to aseptic loosening, and one (1.9%) required revision for infection. Three hips with aseptic loosening failed, due to insufficient screw fixation of the shell in two and pelvic discontinuity in one. The mean Harris Hip Score improved significantly from 55 (35 to 68) preoperatively to 81 points (68 to 99) at the latest follow-up (p < 0.001). Conclusion The reconstruction of acetabular defects with TM shells and augments showed excellent long-term results. Supplementary screw fixation of the shell should be performed in every patient. Alternative techniques should be considered to address pelvic disconinuity. Cite this article: Bone Joint J 2019;101-B:311–316.

Mid Term Results

Purpose: To evaluate the clinical and radiographic mid-term results of short-stem total hip arthroplasty (THA) in patients with osteonecrosis of the femoral head (ONFH). Methods: We reviewed 83 cases that underwent Metha stem between November 2010 and November 2012. The appearance of bone trabeculae development and radiolucent line were reviewed and HHS was recorded at 6 months postoperatively then yearly to evaluate the clinical results. Results: The mean age of patients was 43.8 years with the mean follow-up 69.3 (60–84) months. Harris Hip Score improved significantly from 44.7 preoperatively to 99.6 at the last follow-up ( p < 0.0001). There were 4 cases (4.8%) of intraoperative femoral fractures. There was 1 case (1.2%) of distal stem perforation that had stable bone ingrowth and there was 1 case (1.2%) of 5-mm subsidence, which was then stable at 3 months postoperatively. Bone trabecular development was detected at zone 1 (65.1%), 2 (69.9%), 3 (14.4%), 4 (1.2%), 6 (97.6%) and 7 (81.9%). There was 1 case (1.2%) where radiolucent lines were observed in zones 1 and 7. There was 1 femoral stem revision from periprosthetic fracture 4 years after index surgery and 1 cup revision from aseptic loosening. Kaplan-Meier survivorship with the end point of stem revision for any reason was 98.8% and for aseptic loosening it was 100% at 7 years. Conclusions: The mid-term clinical and radiographic results of the Metha stem in patients with ONFH were promising. Its design enables preservation of the bone stock and the bone trabeculae appear to confirm the assumption of proximal force transmission.

Aseptic loosening in total hip arthroplasty can lead to proximal femoral periprosthetic bone loss. The non-cemented Wagner revision stem achieves primary fixation in the diaphysis. The purpose of this study is to evaluate the results after medium- to long-term follow-up of the Wagner prosthesis for revision of the femoral component for aseptic loosening in total hip arthroplasty with proximal femoral bone loss. We performed 53 femoral revisions for aseptic loosening with the non-cemented Wagner revision stem. Clinical assessment included a modified Harris Hip Score and a radiological evaluation. The mean follow-up was 65 months. The Harris Hip Score improved significantly (42.9 to 72.3). Radiological evaluation revealed 24.5% subsidence (>5 mm) in our population. Nine re-revisions were done, eight in the first post-operative year. The re-revisions were performed for progressive subsidence (five), recurrent dislocations (one), subsidence with low-grade infection (one), false route (one), and aseptic loosening after 75 months (one). The cumulative survival rate of the Wagner stem after 12 months was 85% and 76% after 75 months. A relatively high re-revision rate was observed during the first post-operative year. Analysis of these failures has shown that subsidence may be the result of insufficient primary stability. Adequate pre-operative planning and intra-operative radiological assistance is necessary for perfect primary stability and fixation of the Wagner stem. The re-revision incidence after the first 12 months is 0.45 per 100 implants per year. The prosthesis has good survival potential after proper introduction.

Background: Revision total hip arthroplasty (rTHA) is often complex and has a less reliable outcome than primary total hip arthroplasty. Acetabular reconstruction remains a challenge because of the variable amount of bone loss. This study describes and evaluates a novel technique of acetabular reconstruction using composite bone grafting. Patients and methods: Between June 2005 and January 2012, 108 consecutive patients underwent revision hip arthroplasty in which the acetabular component was revised using composite bone grafting. Of these, 24 were lost to follow-up leaving 84 in the study with a minimum 5-year follow-up. There were 54 women and 30 men with a mean age of 70.1 (31–91) years. All patients were assessed clinically and radiologically after a minimum of 5 years. The primary outcome measures were rate of re-revision, patient-reported outcomes and radiological evidence of loosening. Results: The mean follow-up after revision surgery was 6.9 years (5–10). At operation, 60 patients had an acetabular defect of AAOS stage 3 or more. There was no evidence of loosening in 69 revision acetabular components; 12 showed evidence of non-progressive loosening and 3 patients underwent a re-revision procedure (2 for infection, 1 recurrent dislocation). The mean postoperative Hip Disability and Osteoarthritis Outcome Score (HOOS) was 89.11/100 (95% CI, 87.8–90.5). Scores were significantly improved in patients with a more extensive preoperative defect ( p  = 0.006). The overall patient satisfaction rate at final follow-up was very high. Conclusions: Composite impaction grafting using a layered cement and bone graft technique can give satisfactory clinical and radiological outcomes in the medium- to long-term.

Abstract Introduction Multiple revision hip arthroplasties and critical trauma might cause severe bone loss that requires proximal femoral replacement (PFR). The aim of this retrospective study was to analyse complication- and revision-free survivals of patients who received modular megaprostheses in an attempt to reconstruct massive non-neoplastic bone defects of the proximal femur. Questions/purposes (1) What were general complication rates and revision-free survivals following PFR? (2) What is the incidence of complication specific survivals? (3) What were risk factors leading to a diminished PFR survival? Materials and methods Twenty-eight patients with sufficient follow-up after receiving a modular proximal femoral megaprosthesis were identified. The indications for PFR included prosthetic joint infection (PJI), periprosthetic fracture, aseptic loosening, non-union and critical femoral fracture. Complications were grouped according to the ISOLS-classification of segmental endoprosthetic failure by Henderson et al. Results Overall, the complication-free survival was 64.3% at one year, 43.2% at five years and 38.4% at ten years, with 16 patients (57%) suffering at least one complication. Complications were dislocation in eight patients (29%), PJI in 6 patients (21%), periprosthetic fracture in five patients (18%), and aseptic loosening in six patients (21%). Prosthesis stem cementation showed a lower risk for revision in a cox proportional hazard model (95% CI 0.04–0.93, HR 0.2, p = 0.04). Conclusion PFR with modular megaprostheses represents a viable last resort treatment with high complication rates for patients with severe proximal femoral bone loss due to failed arthroplasty or critical fractures. In revision arthroplasty settings, PFR cementation should be advocated in cases of impaired bone quality.

Purpose. To assess the treatment outcome of revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures using a modular distally cemented stem. Methods. 22 men and 14 women (37 hips) aged 66 to 79 (mean, 70) years underwent revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures. The indication for surgery was periprosthetic fracture with stem loosening and loss of proximal bone stock. The patients were referred from other hospitals after previous surgeries had failed: 8 with 3 previous surgeries, 19 with 2, and 9 with one. Using a transtrochanteric approach, the existing prosthesis was removed and a modular proximal femoral replacement stem was inserted, bypassing the area of proximal femoral fracture and bone loss. The stem was distally cemented. Patients were immobilised within 48 hours of surgery. Results. Patients were followed up for a mean of 14 (range, 8–18) years. The mean Harris hip score improved from 29 (range, 5–40) to 78 (range, 56–88); 24 patients attained excellent or good scores (>80), 10 attained fair, and 2 attained poor scores. The mean healing time was 7 (range, 6–14) months; there was no non-union. Improvement in proximal bone stock was noted on serial radiographs. None of the stems had cement fracture or migration, requiring revision. Two (5%) of the patients had dislocations. Conclusion. Vancouver type B3 periprosthetic femoral fractures can be successfully treated with a distally cemented modular proximal femoral replacement prosthesis.
