Prospective Follow-up of the Prevision Hip Stem With Comparison of Different Implant Variants
Aesculap AG
120 participants
Apr 7, 2026
OBSERVATIONAL
Conditions
Summary
The study design is confirmative for non-inferiority of the functional outcome of the implants and is intended to examine the safety and performance of the Prevision hip stem. The study is an observational post-market clinical follow-up study, and the study sites chose the stem variant depending on their own routine and indication.

Interventions
The Prevision hip endoprosthetic stem is a femoral part of a hip joint endoprosthesis. The system provides cementless and cemented variants. Prevision hip stems are modular with a short proximal and longer distal component, or monobloc hip stems. Modular components are coupled via a Prevision specific conical connection with a torque wrench and a tension nut to apply a predefined torsional moment on the connection. The distal component of modular Prevision stems can be combined with locking screws for additional bone fixation. Both types, the monobloc and the modular, provide a 12/14 taper that serves as a connection for metal or ceramic prosthesis heads. Prevision hip stems are combined at the acetabulum with a cementless or cemented acetabular cup.
