RESULTS OF DELAYED EXCISION OF THE RADIAL HEAD AFTER FRACTURE

Twenty-one patients had a delayed excision of a previously fractured radial head (range, one month to more than twenty years). There were four Mason type-II and seventeen Mason type-III fractures. Five fractures had been associated with a concomitant dislocation of the elbow and four, with an ulnar fracture. All of the patients were evaluated for pain, motion, strength, stability, and function by personal interview, examination, and testing in an upper-extremity-biomechanics laboratory. The average length of follow-up was fifteen years (range, three to thirty-two years). Postoperatively, pain was less severe in 76 percent of the patients and motion was improved in both flexion and rotation in 81 percent. An objective functional index showed that 77 percent of the patients had a good or excellent result while 23 percent had a fair or poor result. This study demonstrates the effectiveness of delayed excision after failure of closed management of fractures of the radial head. Thus, some justification is offered for the initial closed treatment of these fractures, with delayed excision of the radial head to be considered as needed.
