Rare Variations Of Extensor Tendons In The Dorsum Of Hand

ABSTRACT

Extensor digitorum muscle originates from the front of lateral epicondyle of humerus as common extensororigin, the adjacent intermuscular septa and the antebrachial fascia. It divides into four tendons in the distalthird of forearm for the medial four fingers. During routine dissection of back of forearm and dorsum of hand forundergraduate students, we discovered that extensor digitorum muscle was unusually giving a common slip tothe ring and little finger. Also, extensor digiti minimi(EDM) was found to be bifurcating into two separate slips forthe little digit.
