Abstract
Anatomical variations in upper extremity musculature can affect motor function, contribute to neuropathies, or enhance functionality. This clinical case report describes a bilateral anomalous muscle in the forearm, a "flexor digiti minimi longus," originating in the anterior proximal forearm and extending via a distinct tendon to the distal phalanx of the fifth digit. Recognizing such variations is crucial for understanding digit function, guiding orthopedic surgery, and identifying potential neurovascular complications.
