ABSTRACT
INTRODUCTION: This study aims to describe the results of plate fixation in one of the largest single-center cohorts that employs plate fixation as the golden standard. Additionally, risk factors related to a negative outcome were identified. MATERIALS AND METHODS: This was a retrospective cohort study of all patients treated for a humeral shaft fracture in a level-one trauma center between January 2010 and December 2017 with a mean follow-up of 1 year. RESULTS: Plate fixation was performed in 102 patients with a humeral shaft fracture. The mean age was 50 (SD 20) years with 54.9% (n = 56) being male. Forty-eight percent (n = 48) had an AO type-A, 34.3% (n = 35) type-B, and 18.7% (n = 19) type-C fracture. Deep surgical site infections and non-union occurred in 1% (n = 1) and 3.9% (n = 4) of patients, respectively. Revision of the implant was performed in 15.7% (n = 16) mainly due to implant-related complaints. Only one patient developed radial nerve palsy after surgery. The median duration to radiological fracture healing and full-weight bearing was 18 (range 7-65) weeks and 14 (range 6-56) weeks, respectively. Risk factors for negative outcome included higher age, osteoporosis, open and higher AO class fractures, performing surgery during out-office hours, and the use of LCP 3.5-mm plate and an anterolateral approach. CONCLUSION: Plate fixation for humeral shaft fractures has low risks of complications. It should be emphasized that the complications can be further minimized with a greater surgical expertise and by refraining from performing a surgery during out-office hours.
