The posterior neuromuscular compartment of the deltoid.

Abstract

The aim of this study was to define a posterior neuromuscular compartment of the deltoid with adequate innervation and circulation for use as a local transposition flap as well as a functional flap to restore shoulder and elbow function. The nerve supply and blood supply to the posterior one third of the deltoid was studied in 20 cadaveric shoulders. A posterior neuromuscular compartment of the deltoid with adequate circulation and innervation was identified. It was feasible to transpose it for local coverage about the shoulder and to restore shoulder abduction and elbow extension. A posterior neuromuscular functional compartment of the deltoid has been identified.
