description Abstract Background The purpose of this study was to investigate the characteristics, treatment methods, and functional outcomes of children with Dubberley Type IIA capitellar fractures. Methods We conducted a retrospective analysis of pediatric patients diagnosed and surgically treated for capitellar fractures at the Pediatric Orthopedics Department of Sichuan Provincial Orthopedic Hospital from June 2018 to June 2024. Fractures were classified according to the Dubberley system, and functional outcomes were evaluated using the Mayo Elbow Performance Score (MEPS) at the final follow-up. Results Among the cohort, 26 children (22 males, 4 females; age range 9–14 years, mean 13 years) were identified with Dubberley Type IIA capitellar fractures. All patients underwent surgical treatment via a lateral elbow approach: 11 cases received cannulated screw fixation alone, while 15 cases were treated with cannulated screws combined with buttress plates. Follow-up ranged from 8 to 35 months (mean 17.5 months). At the final follow-up, all fractures had healed without complications such as nonunion, osteonecrosis of the capitellum, or heterotopic ossification. The MEPS excellent/good rate was 100%. Conclusions The displacement pattern of Dubberley Type IIA capitellar fractures in children predominantly involves proximal rotation of the lateral aspect of the fracture fragment in the coronal plane, centered on the medial aspect of the fracture fragment. Early and accurate diagnosis combined with surgical intervention resulted in favorable functional recovery and significant therapeutic efficacy. Key factors for successful outcomes include anatomical reduction of the fracture, restoration of joint congruency, stable fixation, and early postoperative functional rehabilitation.
