Extensor indicis brevis Muscle: an Unusual Muscular Variant

Knowledge of anatomical variations of the musculoskeletal system is important for interpreting unusual clinical presentations. We observed the presence of an abnormal extensor indicis muscle in the left hand of an adult male cadaver. In this case, the muscle comes from the ligament and over the scap...
