Macalister reported the variations in flexor digitorum profundus as follows:
The separation of the index finger tendon from the others is a distinctly human characteristic, correlated with the specialization of the index finger. The degree of the muscles freedom varies. It may be quite independent, forming a flexor indicis profundus. The radial origin may extend a considerable distance on the bone alongside the long flexor of the thumb. A tendon to the middle finger may be absent.
A muscular slip (accessorius ad flexorem digitorum profundus)arising from the coronoid process and ending by a long tendon on one or another (usually the index or middle) of the tendons of the muscle has been reported in about 20% of bodies. Mori reported 40% in his subjects. Flexor digitorum profundus (Fdp) may receive a muscular slip from the medial epicondyle of the humerus (1:205 arms, Mori), from flexor pollicis longus 12.5%, and Fdp may be fused with flexor digitorum superficialis in 11% of 205 arms according to Mori.
Syn.: m. Flexor digitorum perforans.
