Abstract
INTRODUCTION Anatomical variations of the extensor muscles of the fingers rarely can be anticipated and sometimes can be neglected when occasionally found during surgery. These anomalous muscles can be the [...]
The current report presented a rare variant of extensor indicis brevis muscle, replacing extensor indicis, in the left hand of an adult male cadaver. The origin of the muscle was reported, for the first time, to be from the distal margins of radius and ulna. The muscle is inserted into the extensor expansion of the index. A new classification for extensor indicis brevis muscle was proposed based on its origin. Awareness of rare anatomical variations would help clinicians and surgeons in accurately managing suspected cases and planning surgical procedures. KEY WORDS: Extensor indicis brevis muscle; Extensor indicis; Anatomical variations.
