Abstract
Background: Previously published reports present a variety of nonoperative and operative treatments for a persistent olecranon physis. However, the radiographic indication for the operative treatment is not clear.
Hypothesis: Our radiographic classification of persistent olecranon physis is helpful in formulating treatment decisions. Study Design: Cohort study; Level of evidence, 3.
Methods: Sixteen male baseball players with persistent olecranon physis were retrospectively evaluated. The mean age at first presentation was 14.7 years (range, 12-17 years). The lesion was classified into 2 stages based on radiographic appearance. Stage I demonstrated widening of the olecranon epiphyseal plate when compared with the contralateral elbow on the lateral view. Sclerotic change indicated stage II. All patients underwent nonoperative treatment for at least 3 months. Follow-up radiographs were taken at 1-month intervals. Operative treatment was provided to the patients whose condition had failed to improve after nonoperative treatment.
Results: Of the 16 patients, 12 had stage I lesions and 4 had stage II lesions. Nonoperative management produced healing in 91.7% of patients with stage I lesions and none of the patients with stage II lesions.
Conclusion: Our radiographic classification of persistent olecranon physis is useful for treatment decision making. In addition, our results demonstrated that sclerotic change is a high predictive indicator of the need for operative treatment.
