Acetabular Defects

Using morselized and structural allograft to restore bone stock for massive acetabular bone defect in revision total hip arthroplasty (THA) is an appealing procedure. However, concerns about inability to achieve long-term stability following allograft resorption remained. From 2003 to 2012, 59 hips in 58 patients undergoing revision THA for Paprosky type II or III acetabular defects were retrospectively reviewed. The acetabular defects were managed with deep-frozen morselized and structural allografts, and a press-fit cementless cup along with supplementary screws. Clinical outcomes and radiographic results were analyzed with a mean follow-up of 8.7 years. The clinical successful rate was 100% for hips with Paprosky type II defect, 95.2% for IIIA defect, and 92.8% for IIIB defect. Three hips with type III defect failed at 4, 7, and 9 years, respectively. Harris Hip Score improved significantly from 60.1 preoperatively to 91.3 at the latest follow-up. All hips with good clinical results showed trabecular bridging in the allograft-host bone interface. Deep-frozen structural and morselized allograft in combination with a press-fit cementless cup represented a viable option to reconstruct acetabular defects in revision THA.

Abstract Background: We proposed a new concept of “iliac extended fixation” in revision total hip arthroplasty (THA) as fixation extending superiorly 2 cm beyond the original acetabular rim with porous metal augments, which was further classified into intracavitary and extracavitary fixation. This study reports the minimum 2 years outcome of the iliac extended fixation technique in patients with Paprosky type 3 acetabular defects. Methods: Thirty two revision THA patients were retrospectively reviewed who underwent reconstruction with the concept of iliac extended fixation from 2014 to 2016 in our hospital. Patients were assessed using the Harris Hip Score (HHS) and the Western Ontario and McMaster Universities Osteoarthritis Index score (WOMAC). In addition, radiographs were assessed and patient reported satisfaction was collected. Results: At an average follow-up of 40 months (range 25 – 64 months), the postoperative HHS and WOMAC scores were significantly improved at the last follow-up (p < 0.001). The postoperative horizontal and vertical locations of the COR were significantly improved from the preoperative measurements (p < 0.05). Two (6.3 %) patients were dissatisfied with the outcome. The extracavitary iliac extended fixation group had significantly more horizontal screws fixation (4.6 ± 25.7° vs 41.9 ± 37.8°, p < 0.001) and higher rate of osteointegration in zone 1A (91.7% vs 50.0%, p = 0.023) than the intracavitary iliac extended fixation group. Conclusions: Intracavitary and extracavitary iliac extended fixation with porous metal augments and cementless cups are effective in reconstructing severe superior acetabular bone defects, with promising short-term clinical and radiographic outcome.
