Axial and torsional stability of an improved single‐plane and a new bi‐plane osteotomy technique for supracondylar femur osteotomies

Abstract

In replicate femurs, the new bi-plane technique improved axial stability, but in contrast to what was theorized, decreased torsional stability, compared to the single-plane technique. The addition of a bi-cortical screw proximally improved stability under axial loading, but not torsion. Further clinical testing will have to prove if early full weight bearing using the new bi-plane technique is possible.
