Abstract:

Introduction: Knowledge of extensor tendons over the dorsum of hand is important for anatomist as well as clinicians to carry out surgical repairs of tendons and to treat pathological conditions associated with tendon.

Aim: To study frequency of occurrence of variations of the Extensor Digitorum Communis tendon slips on the dorsum of hand in South Indian cadavers.

Materials and Methods: Material for the study consisted of 50 formalin fixed adult cadavers (100 upper limbs) of South Indian origin aged between 30 and 70 years old allotted for undergraduate dissection in the Department of Anatomy, Aarupadai Veedu Medical College, Pondicherry.

Observations: Out of hundred dorsums of the hand studied, Extensor Digitorum Communis showed four slips in 95 specimens I.e., one for index finger (EDCI), one for middle finger (EDCL), one for ring finger (EDCR) and one for little finger (EDCS). Variations were observed in five hands, four of right side and one of left side. Maximum tendon slips identified of Extensor Digitorum Communis were 7 in number in one right side hand. In no hand Extensor Digitorum Communis was found with less than four slips.

Conclusion: Complete knowledge of variations in extensor tendons of the hand is very important during reconstructive surgeries and other procedures in treating hand injuries. The findings of the present study may be of use during surgical procedures involving the tendon of Extensor Digitorum Communis.

Keywords: Extensor Digitorum , Tendinous slip, Dorsum of hand.
