“…Minimal bone loss is required for implantation and, in the case of the CUT femoral neck prosthesis, the subsequent favorable strain distribution and prevention of proximal femoral stress shielding after implantation facilitate possible future revision THA. Medium-term survival of the CUT femoral neck prosthesis is satisfactory in these young patients and comparable to that of other femoral neck THAs (Zelle et al 2004, Stukenborg 2007, Corner et al 2008). …”

Background As the number of young patients receiving total hip arthroplasty increases, bone-saving implantations facilitating possible future revision, such as the CUT femoral neck prosthesis, are gaining importance. There have been few medium-term results reported for this prosthesis, however, and its migration pattern has not been analyzed.Patients and methods 39 consecutive CUT femoral neck prostheses were implanted in 32 patients, mean age 37 (17–58) years, with symptomatic osteoarthritis and either less than 55 years of age or with an anatomic anomaly preventing implantation of a diaphyseal stem (n = 1). Patients were followed prospectively using routine clinical examination and radiostereometric analysis (RSA) at 6, 12, 26, and 52 weeks postoperatively and annually thereafter. This study evaluated the 5-year follow-up results.Results The mean Harris hip score increased from 26 (3–51) points preoperatively to 84 (66–98), 86 (55–98), and 87 (47–98) points at 3, 12, and 60 months. 3 stems were revised: 1 after luxation following excessive subsidence due to an undersized component and 2 due to persistent strong thigh pain. 5-year survival was 95% (95% CI: 87–100). Initial migration varied widely in magnitude; median total tip migration was 0.42 mm (0.09–9.4) at 6 weeks, 0.92 mm (0.18–5.9) at 1 year, and 1.10 mm (0.13–6.4) at 5 years. Even after high initial migration, stabilization was achieved in 31 of the 35 RSA-evaluable implants. 3 prostheses showed progressive continuous migration throughout the entire follow-up period, and were considered to be loose, suggesting reduced long-term survival.Interpretation Currently, we cannot recommend the CUT femoral neck prosthesis as a routine treatment option in (young) patients requiring THA. The CUT prosthesis may not reach the 90% survival benchmark at 10 years, and the prosthesis is difficult to implant. If initial stabilization is achieved, however, aseptic loosening is unlikely. A good clinical outcome was seen in the surviving prostheses. We will continue to follow this patient group.

“…Der Anteil der zur Operation führenden Hüftkopfnekrosen ist in dieser Studie mit 6% geringer als in anderen Studien und korreliert nicht mit der Überlebensrate. Eine Korrelation der Ätiologie, insbesondere der in anderen Studien deutlich höher liegende Anteil an Hüftkopfnekrosen (13-44%), mit der Überlebensrate wird in den genannten Studien ebenfalls nicht gesehen [23][24][25][26][27][28][29]. Thomas Die klinisch-radiologische Gegenüberstellung mit den jüngst publizierten Ergebnissen des alternativen Kurzschaftmodells CFP zeigt bei einem ähnlich langen Nachbeobachtungszeitraum vergleichbare Ergebnisse hinsichtlich der ÜLR von 99% und des Abschneidens im HHS mit 96,3 Punkten.…”

“…Bei den kurzen Hüftprothesenschäften gibt es unterschiedliche Modelle, von denen nur wenige über mehr als 5 Jahre dokumentiert sind [1][2][3]. Auch die genaue Definition eines kurzen, gekürz-ten oder schenkelhalserhaltenden Schaftes [4] ist bei den verschiedenen Systemen zu berücksichtigen. Es gibt heute eine Vielzahl neu entwickelter Kurzschäfte [5], die in den letzen Jahren erstmals verwendet wurden und von denen es nur wenig publizierte Frühergebnisse gibt.…”

Our results support the use of the investigated short hip stem for THA when the femoral bone quality and morphology support the metaphyseal anchoring concept. The surgical technique must avoid a stem position without proximal-lateral cortical contact to the femoral osteotomy, as this reduces primary implant stability. Further follow-up is necessary to validate the long-term success of this procedure.
