Anterior-posterior and rotatory instability with and without anterior traction were recorded with roentgen stereophotogrammetric analysis.

Healing after 6 months, intermediate fracture fragments, and a decreased Pauwels' angle seemed to imply increased fracture compression or rotatory instability.

At 20 degree of flexion, none of the braces decreased the internal rotatory instability, whereas one type (modified Lenox Hill) reduced the external rotatory instability.
