Abstract：Objective To explore and summarize clinical experience of ulna osteotomy and extending with orbit external ifxator in the treatment of hereditary multiple exostoses forearm deformity.Methods A total of 25 patients ( with complete data ) of hereditary multiple exostoses forearm deformity underwent surgeries in our hospital from August, 2002 to December, 2012. Clinical data were retrospectively analyzed. Ulna osteotomy and gradual extending with orbit external ifxator were applied. There were 9 males and 16 females with the average age of 7.3 years old ( range: 5-11 years ). Clinical results were assessed according to Gregory criteria.Results The average time of follow-up was 30.2 months ( range: 18-96 months ). The average length of ulna extending was 28mm ( range: 15-40 mm ). All patients healed on the average of 5.2 months ( range: 3.5-8 months ). According to Gregory criteria: excellent in 11 cases, good in 12 cases, fair in 2 cases.Conclusions The ulna osteotomy and extending with orbit external fixator in the treatment of hereditary multiple exostoses forearm deformity can spontaneously reduce the dislocation of the radial head without the need of any additional operative intervention. All patients are satisifed with ifnal results. The elbow and wrist lfexion / extension, wrist radial / ulnar-deviation, forearm pronation / supination are improved markedly compared with preoperative conditions.
