Prospective Follow-up of the Prevision Hip Stem With Comparison of Different Implant Variants

"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."
