Reconstruction of forearm deformities in multiple cartilaginous exostoses

The management of complex forearm deformities in patients with multiple cartilaginous exostoses is controversial. The objective of this study is to look into the outcome of treatment with the combined use of ulna lengthening, radial osteotomy, and excision of exostosis in our six patients, who all had Masada type 1 deformity of the forearm. Clinical assessment was performed using the pre- and postoperative range of motion of the wrist, forearm and elbow. The chief symptom each patient had was noted as well as the demographic data of all patients. Radiological assessment was performed by checking the degree of negative ulna variance, the radial articular angle, and the degree of carpal slip. The degree of satisfaction of the patients and their parents were noted. Good clinical and radiological results were obtained at a mean follow-up of 2.5 years. All patients and parents were satisfied and there was no recurrence of deformity in the latest follow-up. The authors believe in early and aggressive treatment of Masada type 1 deformity of the wrist and forearm for multiple cartilaginous exostoses with a combination of excision of exostosis, ulna lengthening and radial osteotomy.
