Additionally, a universal modular neck adapter (Bio-Ball®, Merete, Berlin, Germany) which is connectable to standard hip stems (12/14 taper) was included. This adapter was combined with a CF30®-stem (Zimmer, Warsaw, IN, USA). The Metha® and SPS-Modular® taper shapes were oval, designed with a stem connection.
AESCULAP® Metha® Short Hip Stem System. By B. Braun. January 24, 2022. Metha represents a short stem protheses system. The stem finds its anchoring in the closed femoral neck ring. It protects the trochanter major region and supports minimal invasive surgical approaches. The implant portfolio consits out of different CCD ancles.
Metaphyseal total hip arthroplasty (METHA) The METHA (Aesculap) is an uncemented neck-retaining monoblock or modular stem (Fig. 2). It is made of a …
