Abstract:: Only few reports have described the outcome of pediatric patients following radial head resection. Therefore, the aim of the present study was to assess clinical and radiologic outcome of patients with open physes following resection of the radial head. Skeletally immature patients treated with resection of the radial head were included. Range of motion (ROM) of the elbow joint was compared with preoperative values. Grip strength, pronation and supination strength, and carrier angle were compared with the unaffected side. Radiographs were assessed for signs of arthrosis, radial migration, and perifocal ossification. Disabilities of the Arm, Shoulder and Hand and Mayo Elbow Performance scores were obtained. The study included 7 patients (mean age, 11 years), 5 with post-traumatic and 2 with congenitally impaired elbow joint motion. Mean follow-up was 47 months. Pronation/supination ROM improved significantly (P = .018). Extension/flexion ROM did not improve significantly (P = .122). Although grip strength (P = .027) and pronation strength (P = .028) of the affected side were significantly lower compared with the contralateral side, supination strength did not differ significantly (P = .176). The carrying angle was increased in 3 patients. Significant radial migration occurred (mean, 3 mm; standard deviation [SD], 3 mm; P = .018). Arthrosis was found in 3 patients. The mean Disabilities of the Arm, Shoulder and Hand score was 16.1 (range 8.8-30.8; SD, 10.1) and mean Mayo Elbow Performance Score was 88 (range, 70-100; SD, 12). Radial head excision may be considered for selected patients with open physes in cases of severe impairment of pronation/supination. However, sequelae such as radial migration, arthrosis, and elevation of the carrying angle should be expected. Copyright © 2018 Journal of Shoulder and Elbow Surgery Board of Trustees.
