Traumatic Absence of the Shaft of the Radius in a Child: A 15-Year Follow-up after Reconstruction by a Modified Define's One Bone Forearm Procedure

Myung-Sang Moon et al. Clin Orthop Surg. 2018 Jun.

Abstract

Traumatic absence of the entire radial shaft in children has not been reported though there are a few reports of adult cases. We report a 5-year-old boy with traumatic absence of the entire right radial shaft. The Define's reconstruction procedure was chosen to localize the surgery only to the distal forearm and avoid further additional damage to the forearm muscles. The child's forearm was successfully reconstructed by the authors' modified Define's procedure, which was followed until his maturity. Hand function was well maintained.
