Quadratus Femoris
Abstract
Quadratus femoris may be fused with the inferior gemellus or with adductor magnus, replaced by a large inferior gemellus or oturator internus, or may be absent altogether (1-2%). It may be divided at its femoral insertion into two parts: one posterior, with the normal attachment, and the other anterior, with insertion onto the intertrochanteric crest. Hallett and Schwegel reported it absent and replaced by an unusually thick (large) obturator internus muscle. Syn.: Quarré fémoral.
