An anomalous arrangement of the flexor musculature of the forearm and hand

Authors


Abstract

During a routine dissection, an anomalous arrangement of the flexor musculature of the hand was discovered. This bilateral anomaly included a deficient superficialis tendon to the index finger and the little finger and an absence of the fourth lumbrical muscles. The deficiency of the sueperficialis tendons to the index fingers was compensated for, however, by an anomalous muscle in each palm.

The literature was searched both for related cases and for embryologic and phylogenetic background with which to explain the presence of this unusual combination of anomalies.
