A Cadaveric Study of Anatomical Variations of the Hand Extensors

Foream and dorsum of the hand region of 13 cadavers were dissected to investigate the anatomy of the extensor tendons. In the left hand double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons. In the left and right hand the extensor digitorum there was a single tendon to the index. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd. intermetacarpal space; type 3, between the extensors tendons in the 4th intermetacarpal space. Anatomical variations may be beneficial for hand surgeons performing graft operations
