A comparison with cutaneous innervation patterns found in other population groups revealed three new variants which have not been reported in the other populations.
Our study suggests that during arthroscopic resection using superior Bell's portal and medial portal, suprascapular notch hence the suprascapular nerve would have safe margin of more than 10 mm from the resection site on upper border in 85.9% cases and would be vulnerable to injury in 14% cases. The procedure would be safer in patients with a wider scapula.
The use of superficial fibular nerve (Sfn) as a potential donor nerve in nerve grafting has been introduced. The limited availability of donor nerves has paved the way for nerve allografting. We studied the sensory portion of Sfn in 60 limbs from 30 fetuses. Three distinct patterns of the nerve were designated as Types 1, 2, and 3 by us. Type 1 (66.67%) comprised Sfn piercing fascia cruris then branching into Mdn and Idn. Type 2 (21.67%) was a pattern where Sfn penetrated deep fascia then continued undivided over the dorsum of foot. Type 3 (11.67%) was where Mdn and Idn penetrated deep fascia independently. The study provided quantitative measurement data of the sensory portion of Sfn and its branching nerves with respect to osseous landmarks like the head of fibula and the malleoli. Such data may be of help in defining nerve segments suitable for harvesting in nerve grafts from fetuses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
