Rotational Corrective Osteotomy for Malunited Distal Diaphyseal Radius Fractures in Children and Adolescents.

PURPOSE: To report our method of computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fractures in children and adolescents using a custom jig and to review the results of 4 cases.

METHODS

Four patients (mean age, 13 years; range, 11-16 years) underwent computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fracture using a custom jig. We retrospectively evaluated their radiographic and clinical data.

RESULTS

In patients who had marked restriction of forearm supination before osteotomy, the mean arc of forearm supination improved from 5° before surgery to 79° after surgery. Angular deformity on x-ray, range of forearm rotation, and grip strength all improved after surgery. Mild and moderate pain reported by 1 and 2 patients, respectively, was resolved after surgery.

CONCLUSIONS

Computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fracture in children and adolescents using a custom jig is a strategy that facilitates the surgical procedure by accurately correcting both rotational and angular deformities on 1 plane in a single procedure.
