EVALUATION OF SHOULDER JOINT REHABILITATION AFTER SURGERY OF PROXIMAL HUMERUS FRACTURE WITH THE SUPPORT OF 3D PRINTING MODELS PRIOR TO SURGERY

Abstract

46 patients (patients) with proximal humerus fractures were operated on at Thong Nhat Hospital from January 2019 to April 2024. They were divided into 2 groups, group 1: 22
patients with the support of 3D printing models and group 2: 24 patients without 3D models. All patients were open reduction and internal fixation with a locking plate on the proximal humerus. The patients were evaluated for bone healing and deformity on X-ray, and shoulder function was assessed according to the Constant scale. Surgical time of group 1 (90.68 ± 13.029) was shorter than group 2 (105.25 ± 12.037). Mean blood loss of group 1 (164.55 ± 50.042) was less than group 2 (218.75 ± 28.789). Shoulder function were very good and good, accounting for a high rate of 82.6%, and there was no difference between the 2 groups. Postoperative complications had a low rate and there was no difference between the 2 groups in wound surface infection and subacromial conflict. Complications of screw perforation, osteomyelitis,
and bone nonunion have not been observed.
