Abstract：Objective To explore the effect of gradual ulnar lengthening combined with excision of exostoses to treat ulnar shortening deformity in children with hereditary multiple exostoses (HME). Methods 7 children with multiple exosto-ses shortening of the ulnar deformity, admitted to our hospital during June 2011 and August 2014 underwent gradual ulnar lengthening combined with excision of exostoses. The average of ulnar shortening was 2. 6 cm. According to the type of stand-ard clinical HME of the forearm, 4 cases were type ⅡA and 3 cases were type I1b. The technology of Orthofix external fixa-tion combined with excision of exostoses was used. According to the plan, the postoperative limb was extended with appropri-ate functional exercises. Results The mean follow-up time was 22 months. 7 cases in middle piece of ulnar extended 2. 5 ~4. 0 cm (average 3. 2 cm), and all the patients were healed. Wrist ulnar deviation was corrected, forearm rotation function was restored, wrist and elbow joint function was improved. All the patients had no peri operational period and long-term com-plications. Conclusion Short-term clinical effect of the application of Orthofix external fixation combined with excision of ex-ostoses in the treatment of ulnar shortening deformity in children with HME is obvious with smaller invasion and fewer compli-cations.
