Corrective osteotomy using Hoffmann II external fixators for extra-auricular malunion of the distal radius

The authors present the technique and clinical results of a corrective osteotomy for malunion following extra-articular fractures of the distal radius. External fixation allows restoration of the length of the radius with minimal damage to the periosteum. It allows early mobilization of the radiocarpal joint. The position of the distal pins provides intraoperative visual control of the angular correction. The minimal invasive approach decreases the risk of iatrogenic lesion of an extensor tendon or a sensitive branch of the radial nerve. This technique is easy and reliable.
