Severely displaced proximal humeral epiphyseal fractures: a follow-up study.

Forty-eight patients with severely displaced proximal humeral epiphyseal fractures were reviewed. Twenty-one patients were followed up for an average of 9 years after injury with a personal interview, examination, and radiographs. Average age was 14.1 years, half of whom were age 15 years or older. Initial head-shaft displacement averaged 80%, and 31 fractures were displaced by > or = 80%. All underwent attempted closed reduction. Radiographs for all except three were sufficient to judge the adequacy of reduction. Twenty-six of 45 attempted closed-reductions failed to improve displacement significantly. Nine patients underwent operative treatment, and the remainder had a closed reduction. In the operative group, complications occurred in three of nine patients. No complications occurred in the nonoperative group. No patients seen at late follow-up identified any activity or employment restrictions as a result of their injuries. Several patients incurred humeral shortening or imperfect radiographic remodeling, but this did not correlate with clinical outcome. Comparing the operative complications with the excellent late results after nonoperative treatment in this series supports previous recommendations to avoid operative intervention with few exceptions. The magnitude of displacement alone does not appear to justify operative treatment.
