Madelung Deformity: Surgical Correction with Radial Dome Osteotomy

Abstract

Madelung deformity is a rare wrist malformation caused by a growth disturbance of the palmar and ulnar part of the distal radial physis. The aim of this study is to evaluate the outcome of radial dome osteotomy in patients affected by Madelung deformity. The endpoint of this operation is to improve the orientation of the articular surface of the radius, so as to support to the carpal bones. Between 2017 and 2019, in our clinic, 4patients were treated usingthis technique. Postoperative pain was evaluated using the NRS. Functional outcomes were assessed through evaluation of ROM, grip strength via Jamar dynamometer and using DASH questionnaire. The aesthetic defects were estimated using a section of the Michigan Hand Outcome Questionnaire. Correction of deformities was evaluated on post-operative RX using McCarrol Criteria. Were also analyzed the accuracy and tolerance of the plates used.
