Abstrakt:	Background: Pediatric supracondylar humerus (SCH; AO/OTA13-M/3.1) and medial epicondyle fractures (AO/OTA13u-M/7.1) are common. Concomitant SCH with ipsilateral medial epicondyle fractures remain scarcely reported. We investigated the epidemiology, treatment, and outcomes of this rare, combined injury. Methods: A retrospective review of pediatric patients with concomitant SCH and medial epicondyle fractures at a level 1 hospital from 2010 to 2020 was performed. Patient data, treatments, and outcomes were assessed. Radiographs were reviewed for fracture classification and alignment. Patients aged above 18 years and those with inaccessible imaging were excluded. Descriptive statistics were performed. Results: Of 3344 patients undergoing surgery for SCH fractures, 14 (6 females, mean: 10.59 y) with concomitant SCH and medial epicondyle fractures were included. Overall, 28.6% of patients exhibited preoperative nerve palsies (3 PIN, 1 median nerve). There was 1 flexion type and 13 Gartland type III SCH fractures. Medial epicondyle fracture displacement averaged 4.13 mm (range: 2 to 7 mm). Thirteen medial epicondyle fractures occurred medial to the physis with 1 through the physis. Eight patients (57.1%) had medial fixation-7 medial pins, 1 medial screw-which captured both the medial epicondyle and medial column of the SCH fracture. Six medial epicondyles were treated closed. The average time to pin pull was 33.1 days (range: 27 to 51 d) with average follow-up of 138.6 days (range: 27 to 574 d). Overall, 50% of patients completed physical therapy (PT). Complications occurred in 4 cases: prominence of a medial pin, 1 patient required additional PT and dynamic splinting for loss of functional extension, 1 patient underwent a manipulation under anesthesia 3.5 months postoperatively for flexion contracture, and 1 patient developed medial epicondyle nonunion and SCH malunion that underwent corrective osteotomy 10.5 months postoperatively. Conclusions: Concurrent SCH and medial epicondyle fractures exhibited a high rate of nerve palsy (28.6%) and complications (28.6%) and were frequently referred to physical therapy. While patients treated without medial fixation went on to union, this combined injury might represent a relative indication for medial pinning of the SCH fracture. Further studies on this rare injury pattern are needed to determine optimal treatment methods. Level of Evidence: Level IV-therapeutic.
