AN ANATOMICAL STUDY OF SUPERFICIAL PALMAR ARCH IN WESTERN RAJASTHAN POPULATION

The supercial palmar arch is an anastomosis formed mainly by the Ulnar artery with variable contribution from branches of radial Artery. It passes medial to the hook of the hamate, then curves laterally to form an arch that is convex distally and level with a transverse line through the distal border of the fully extended pollicies base. About a third of the supercial palmar arches are formed by the ulnar artery alone; a further third are completed by the supercial palmar branch of the radial artery; and a third by the arteria radialis indicis, a branch of either arteria princeps pollicis or the median artery. The supercial palmar arch is covered by palmaris brevis and the palmar aponeurosis and it is supercial to exor digiti minimi, branches of the median nerve and the long exor tendons and lumbricals.

The Arterial Supply of the Thumb, First Web and Index Finger and its Surgical Application

A detailed examination of twenty cadaver hands has been carried out in order to elucidate the arterial blood supply of the thumb, first web, and index finger, relating this to revascularization, replantation and possible flaps in that area. The vessels are described in turn, and it is demonstrated that the terms “princeps pollicis” and “arteria radialis indicis” are misnomers. The results of the dissections are compared to those of others and the differences recorded.
