Abstract:
BACKGROUND:Manual reduction or traditional steel plate fixation is commonly used for repair of proximal humerus factures in older patients, because of poor stability, making these injuries prone to fracture malunion. While open reduction with steel plate fixation has a better outcome than closed reduction, the stability of internal fixation is stil less than satisfactory. Clinical studies have shown that minimal y invasive treatment with locking compression plates has presented good clinical results in terms of fixation stability, bone healing, and functional recovery. Therefore, we hypothesize that use of a locking compression plate wil provide better stability and that biocompatibility wil potentiate fracture healing and shoulder function recovery in older patients with proximal humerus fractures. OBJECTIVE:To observe the improvement of minimal y invasive treatment with locking compression plates in older patients with proximal humerus fractures. MEHTODS:This prospective, single-center, randomized control ed clinical trial wil be completed at the Department of Joint Surgery, Affiliated Hospital of Qinghai University in China. Eighty-two older patients with proximal humerus fractures wil be enrol ed and equivalently assigned to two groups. In the test group, patients wil undergo closed reduction via a lateral approach to the shoulder fol owed by locking compression plate fixation using a minimal y invasive technique, and those in the control group wil be subjected to closed reduction via a lateral approach to the shoulder fol owed by conventional steel plate fixation using a minimal y invasive technique. Al patients wil be fol owed up for 6 months. The primary outcome wil be recovery of shoulder function as indicated by clinical outcome scores according to the Neer classification system for proximal humeral fractures 6 months after surgery. The secondary outcomes wil include the operation time;intraoperative blood loss;postoperative hospital stay;fracture healing time;clinical outcome scores according to the Neer classification system 0.5, 1, and 3 months after surgery;visual analogue scale scores 1 and 3 days and 1 and 2 weeks after surgery to assess pain;scores of the Medical Outcomes Study 36-item short form health survey 0.5, 1, 3, and 6 months after surgery to assess quality of life;and X-ray examinations 0.5, 1, 3, and 6 months after surgery to assess fracture healing. The experiment was approved by the Ethics Committee of Affiliated Hospital of Qinghai University of China (approval No. QHY1005D). Participants were informed to the test content and treatment process, and signed informed consent. DISCUSSION:This study protocol represents an attempt to objectively choose appropriate methods for internal fixation of proximal humerus fractures in older patients by comparing locking compression plate and conventional steel plate fixation to improve shoulder function. TRIAL REGISTRATION:This trial was registered with the ClinicalTrials.gov identifier:NCT02784522;on 19 May 2016.
