Excision of the radial head in patients younger than 18 years.

We evaluated the results of an excision of the radial head in 25 patients (27 operated-on elbows) younger than 18 years with stiff painful radiocapitellar joints. The mean age was 14.2 years (range, 4.6-17.8 years) with average follow-up of 7.8 years. Analysis of the results with a postoperative elbow score revealed excellent or good results in 19 of the 27 elbows of patients. Skeletal maturity of the patient did not alter the results based on the rating scale. Revision surgery to remove appositional bone growth was needed in six of the 12 posttraumatic cases and one of 15 developmental elbows. Cubitus valgus, wrist pain, and ulnar neuropathy were not clinical problems at follow-up examination. Excision of the radial head was beneficial for 70% of patients younger than 18 years with stiff, painful radiocapitellar joints. Results were not improved in patients who had reached skeletal maturity.
