Radioulnar Synostosis Using a Vascularized Pedicled Radial Periosteal Flap for Supination Deformity in Residual Brachial Plexus Birth Injury.

Supination posture is a common secondary deformity in brachial plexus birth injury (brachial plexus birth injury) that results in functional upper limb impairment.

This report evaluates outcomes in a series of children with forearm supination deformity and complete pronation palsy secondary to severe brachial plexus birth injury undergoing radioulnar synostosis in slight pronation using a novel proximal pedicled vascularized radial periosteal flap (vascularized radial periosteal flap).
