The aim of this study is to investigate the mid-term results of 29 hips in 26 patients who underwent acetabular reconstruction using a Kerboull-type acetabular reinforcement device and impaction with hydroxyapatite (HA) granules. The acetabular bone defects were AAOS type II for six hips and type III for 23 hips. The mean Merle d’Aubigné clinical scores were significantly improved after operation. Six hips developed implant migration and breakage, and five of six hips were revised after an average of 5.5 (range 2.0–8.8) years. All hips with thickness of the grafted HA less than 10 mm were stable. As the HA became thicker, the failure rate were significantly increased. The Kaplan–Meier survival rates at 10 years were 73.2%, with 100% and 67.0% for AAOS type II and III defect respectively as the end point was failure condition. Reconstruction using a Kerboull-type acetabular reinforcement device and impaction with HA granules was an alternative method in the absence of adequate allografts.

Arthroplasty Revision

Background: There is a trend for using jumbo cups/oblong devices for acetabular reconstruction as alternative to biological solutions. We report about a spectrum of reconstruction methods and their mid-term results. Methods: Inclusion of 214 consecutive patients undergoing total hip arthroplasty revision surgery. Patients were examined using the Harris Hip Score (HHS). Based on the intraoperative acetabular defect situation, cases were classified into 1 of 5 possible categories of a stability classification for acetabular replacement (SCAR). Results: Mean HHS improved from 42 preoperatively (range 12–62) to 77 (range 54–90; p < 0.05) 6 months after operation. There were significant differences of the pre-and postoperative HHS between SCAR subgroups ( p < 0.05). Inter-observer reliability of the SCAR was high (kappa 0.94 (95% CI, 0.90–0.98)). Re-revision was performed in 15 cases (7%). Conclusion: The SCAR classification is a practicable tool for intraoperative decision-making as it provides standardised treatment recommendations.

AimsThe advent of trabecular metal (TM) augments has revolutionized the management of severe bone defects during acetabular reconstruction. The purpose of this study was to evaluate patients undergoing revision total hip arthroplasty (THA) with the use of TM augments for reconstruction of Paprosky IIIA and IIIB defects.Patients and MethodsA retrospective study was conducted at four centres between August 2008 and January 2015. Patients treated with TM augments and TM shell for a Paprosky grade IIIA or IIIB defect, in the absence of pelvic discontinuity, and who underwent revision hip arthroplasty with the use of TM augments were included in the study. A total of 41 patients with minimum follow-up of two years were included and evaluated using intention-to-treat analysis.ResultsThere were 36 (87.8%) patients with a Paprosky IIIA defect and five (12.2%) patients with a Paprosky IIIB defect. The mean age was 56.7 years (28 to 94). There were 21 (51.2%) women and 20 (48.8%) men. The mean follow-up was 39.4 months (12 to 96). One (2%) patient died after eight years. No failures were noted in the series. The mean survivorship was 100% at the time of latest follow-up.ConclusionThe results of this multicentre study showed encouraging short- and mid-term results for the use of TM augments in the management of Paprosky grade IIIA and IIIB defects.

Background: The direct anterior approach has gained popularity in total hip arthroplasty (THA) over the past decade. However, there are few reports that describe the use of this approach for cases of complex revision. The purpose of this study was to report the surgical procedure and early clinical results of acetabular revision in the presence of bone defects using a Kerboull-type reinforcement device through the direct anterior approach. Methods: Eleven patients who had undergone acetabular reconstruction using a Kerboull-type reinforcement device for aseptic or septic loosening bone defects were enrolled. All procedures were performed using the direct anterior approach on a standard operating table. The mean age was 71.8 years, the mean period from initial surgery to revision THA was 14.5 years, and the mean follow-up period was 19.8 months. Results: The Kerboull-type acetabular reinforcement device with cemented cup combined with allogenic femoral head bone grafts was used in all hips. The mean operative time and intraoperative blood loss were 148 min and 743 g, respectively. None of the patients required allogeneic blood transfusion. One patient required revision surgery 11 months postoperatively because of device displacement. No other major or minor orthopedic complications were observed. Conclusion: The direct anterior approach allows for less invasive acetabular reconstruction using a Kerboull-type reinforcement device.
