ONS IN THE FORMATION OF EXTENSOR EXPANSION AND INTRINSIC MUSCLES OF THE LEFT HAND.

VIMALA V

Abstract


Extensor digitorum muscle and its dorsal digital  expansion formation have a complex anatomical structure. Knowledge of this complex structure is very important in this era of reconstructive surgeries. During a routine dissection in the Department of Anatomy, we encountered variations in extensor tendons, lumbricals and first palmar interosseous muscle in the left hand. We observed that the extensor digitorum muscle in the left hand had a doubled tendon for middle and ring fingers. Extensor digiti minimi muscle had three tendons. The    intertendinous connections between the tendons of extensor digitorum muscle had type 3y in 3rd intermetacarpal space. Theproximal end of lumbricals was in the carpal tunnel. The 4th lumbrical was unipennate. First palmar interosseous was           absent.
