“…The CUT stem demonstrated a mean survivorship of 96.4% (69.6% to 100%) at a mean follow-up of five years (3 to 8) in 690 hips, 60 – 67 with aseptic loosening as the endpoint. The mean HHS was 92 points (85 to 98) at the final follow-up assessment in 690 hips, 60 – 67 while the mean incidence of thigh pain was 2.9% (1% to 5.1%). The mean intra-operative peri-prosthetic fracture rate was 0.6% (0% to 2.4%) and the mean incidence of > 2-mm subsided stems was 3.4% (0.8% to 7.7%).…”

Over the last two decades, several conservative femoral prostheses have been designed. The goals of conservative stems include: the spearing of the trochanteric bone stock; a more physiological loading in the proximal femur reducing the risk of stress shielding; and to avoid a long stem into the diaphysis preventing impingement with the femoral cortex and thigh pain.All stems designed to be less invasive than conventional uncemented stems are commonly named ‘short stems’. However, this term is misleading because it refers to a heterogeneous group of stems deeply different in terms of design, biomechanics and bearing. In the short-term follow-up, all conservative stems provided excellent survivorship. However, variable rates of complications were reported, including stem malalignment, incorrect stem sizing and intra-operative fracture.Radiostereometric analysis (RSA) studies demonstrated that some conservative stems were affected by an early slight migration and rotation within the first months after surgery, followed by a secondary stable fixation. Dual-energy x-ray absorptiometry (DEXA) studies demonstrated an implant-specific pattern of bone remodelling.Although the vast majority of stems demonstrated a good osseointegration, some prostheses transferred loads particularly to the lateral and distal-medial regions, favouring proximal stress shielding and bone atrophy in the great trochanter and calcar regions.Cite this article: EFORT Open Rev 2018;3:149-159.

“…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.…”

“…Außer kurzfristiger Ergebnismitteilungen existiert lediglich eine Studie, die sich mit den mittelfristigen Ergebnissen der CUT-Prothese befasst (ca. 5 Jahre) [10]. Anhand der Auswertung der eigenen Operationen des Zeitraums Januar 2000 bis Mai 2001 soll geklärt werden, ob die Prothese die Anforderungen, die an ein Schenkelhalsimplantat zur Versorgung junger Patienten zu stellen sind, mittel-bis längerfristig erfüllt oder nicht.…”

The analysis of the eight-year follow-up of 82 CUT prostheses shows that the implant does not fulfil our expectations of a femoral neck prosthesis, in spite of the possibility of a less invasive and bone-saving implantation technique. In view of unacceptable survival rates, valgisation changes of the joint geometry and critical changing procedures, from our point of view the femoral neck prosthesis CUT does not represent a recommendable alternative implant in young, active patients.
