The optimum treatment for periprosthetic joint infection (PJI) of the hip with substantial bone defects remains controversial. A retrospective assessment was performed for 182 patients treated for PJI with a two-stage protocol from 2005 to 2015. Implant removal and debridement were followed by Girdlestone arthroplasty or spacer implantation. The results of the Girdlestone and spacer groups were compared. There were 71 cases that received spacers, and 111 Girdlestone procedures were performed. After the first stage, 26.37% of cultures were negative, and among patients with a detected pathogen, methicillin-sensitive Staphylococcus aureus was the most common organism (41.79%). Acetabular and femoral bone defects, according to the Paprosky classification, were more severe in the Girdlestone group (P

Cortical bone loss in revision hip arthroplasty requires an adequate stabilization to achieve a durable implant fixation. This case series shall illustrate possible indications for the use of allogenic grafts in revision hip arthroplasty. Twelve patients with femoral bone loss were treated with allografts. In addition to established clinical scores, the radiological follow-ups were analyzed for hints of implants loosening and the osteointegration of the allografts. After a mean follow-up of 3.0 years the mHHS was 61.3 points and the UCLA 3.8. One patient showed a non-progressive radiolucency around the hip implant. The osteointegration of all allogenic grafts happened on time. Up to the last follow-up no revision surgery of the hip implants and the associated femoral bone graft was observed. Allogenic bone grafts present a method for biological stabilization in situations of large femoral cortical bone defects in revision hip arthroplasty.

Acetabular and femoral bone defects, according to the Paprosky classification, were more severe in the Girdlestone group (P<0.05). During the follow-up (mean, 5.95 years), the overall incidence of complications was 21.42%. The mean Harris hip score was significantly lower in the Girdlestone group (68.39 vs 77.79; P<0.0001). The infection recurrence rate reached 8.79%. Despite satisfactory infection control, the number of complications and poor functional outcomes associated with resection arthroplasty indicate the necessity for development of different approaches for patients with advanced bone loss.
