A CADAVERIC STUDY EVALUATED THE RISK OF NERVE INJURY DURING DORSAL PORTAL WRIST ARTHROSCOPY
Main Article Content
Abstract
Introduction: Nerve damage following wrist arthroscopy are frequently attributable to the procedure of developing dorsal wrist portals. The goal of this study was to figure out how the distance between the portals affected the risk of nerve damage around them. Method: A descriptive research of a series of cases was conducted at the Department of Anatomy, University of Medicine and Pharmacy, in Ho Chi Minh City, Vietnam, from May to June 2021, using 30 wrist joints from 15 fresh cadavers of Vietnamese adults. Results: The mean distances from the sensory branch of the radial nerve to portals 1-2, 3-4, and 4-5 are 6.84mm, 18.36mm, and 28.62mm, respectively; the distance from the dorsal sensory branch of the ulnar nerve to the portals 6R and 6U is 13.11mm and 6.85mm, respectively; and the distance from the posterior interosseous nerve to portals 3-4 and 4-5 is 8.20mm and 7.84 mm, respectively. Conclusions: When the dorsal wrist portal is formed during wrist arthroscopy, the superficial branch of the radial nerve, the dorsal sensory branch of ulnar nerve and the posterior interosseous nerve may be damaged.
