Abstract :

The hand in the humans is supplied with blood by two anastomotic arches; they are be¬ing the superficial palmar arch (SPA) and the deep palmar arch (DPA). Both the arches are constituted by radial and ulnar arteries. This study on superficial palmar arch was performed on 20 cadavers, out of the 20 cadaver 16 cadavers are male and 4 cadavers are female. In the 20 cadavers 20 right hands and 20 left hands total 40 hands are dissected in the Department of Anatomy of Gitam Medical College, Visakhapatnam, A.P. In the present study incomplete superficial palmar arch are formed entirely by ulnar artery without anastomosing with radial artery and supplying thumb and index finger was found in 8 out of 40 hands with an incidence of 20%. In one of the right upper limb showing the hypertrophied first lumical were observed. The superficial palmer arch variation in the hands is essential for surgeons, radiologists and anatomists because of innovative microsurgical techniques in reconstruction of a traumatized hand. The hypertrophied first lumical muscle may lead to the compression of radial collateral digital arteries leading to chronic sub –ischemia of fingers.
