The purpose of the use of an osteotomy for the treatment of osteonecrosis (ON) of the femoral head is to move the necrotic segment away from the major load-transmitting area of the acetabulum and to redistribute the weight-bearing forces to articular cartilage that is supported by healthy bone. The most common osteotomies are the varus, valgus, flexion, rotational (Sugioka), and combined osteotomies. Their long term outcome, reported in the literature, is quite controversial. We found a decreasing frequency of flexion osteotomies between 1986 and 1996 performed at our department. In 1977 we started with the Sugioka osteotomy in special cases of femoral head ON (necrotic angle in the AP-view about 90 degree) resulting in a total of 51 cases. Forty-one of them have been analyzed regarding complications, reoperations and Harris Hip Scores. Seventeen of 41 patients developed complications and underwent reoperation. Nevertheless the results according to the Harris Hip Score were satisfactoy (excellent and good in 24 patients fair in 10 and poor only in 7 cases). Independently from the size of the necrosis total hip arthroplasties have been performed in 8 cases. The survival curve of 41 Sugioka osteotomies shows a 50% decrease at 6 years. Due to this fact and the regression in the number of osteotomies of the femur in cases of ON of the hip joint we find in our material that the importance of osteotomies has dramatically decreased in contrast to the excellent results of total hip arthroplasty.

Objective The purpose of this study was to retrospectively evaluate the complications and long-term outcomes of total hip arthroplasty (THA) using a hybrid cementless system. Materials and Methods Medical records of dogs that underwent THA using a combined implant system consisting of Innoplant Screw Cup, Kyon taper head and Zurich cementless (Z-THA) stem between March 2010 and March 2015 were reviewed. Dogs with a minimum follow-up of 2 years were included. Signalment, complications and outcome at the latest follow-up examination were recorded. Results Sixteen hybrid THA were performed in 12 dogs. Mean follow-up was 42.5 months. Overall complications occurred in three arthroplasties (19%) including luxation (n = 1), aseptic cup loosening (n = 1) and implant failure with screw breakage followed by stem subsidence (n = 1). Two arthroplasties including prosthesis luxation and aseptic cup loosening were successfully revised using the here described hybrid system and achieved full functional outcome at the last follow-up examination. One arthroplasty with screw breakage and secondary stem subsidence was treated conservatively and achieved an acceptable outcome. Conclusion Hybridization of the Innoplant Screw Cup, Kyon taper head and Zurich cementless for initial THA surgery is feasible. In comparison with the reported complications and outcomes for single implant THA systems, the hybrid THA did not prove to have greater clinical benefits for use in primary THA surgery.

Introduction: The purpose of the present study was (i) to review the long-term outcome of cemented Charnley total hip replacements (THRs) performed by 1 surgeon (GH), 20 to 42 years ago, in patients ≥60 years, using both the Kaplan-Meier (KM) and the cumulative incidence (CI) methods, and (ii) to compare the estimations of the 2 statistical methods. Methods: We evaluated the outcome of 306 consecutive primary cemented THRs that were performed in 265 patients. The final clinical, radiographic assessment and satisfaction of living patients were also included. The survivorship was estimated with the use of KM and CI methods and the relative difference between their estimations was calculated. Results: Living patients’ final clinical results were significantly improved in comparison with respective preoperative ones, and all the acetabular and 91% of femoral components considered as well fixed. 95% of these patients reported satisfaction. The risk of revision at 25 years, with revision for aseptic loosening for 1 or both components as the endpoint, with 21 hips at risk, assessed with KM analysis was 6.9% and with CI approach was 3.9%. The relative difference between KM and CI estimations was increasing during follow-up, reaching up to 76.8% at 25 years. Conclusions: We concluded that fixation of implants with cement in older patients had satisfactory long-term results and can serve as a benchmark with which to compare newer fixation methods (hybrid and uncemented) and materials. However, KM method, in studies that include older population with long-term follow-up, may significantly overestimate the risk of revision and clinicians could consider using besides the cumulative incidence of competing risk method.
