Abstract
INTRODUCTION: in this study, we aimed to compare the clinical and radiological results of single 4.5 mm locking compression plate (LCP), dual 3.5 mm LCP and intramedullary nailing (IMN) methods applied to the surgical treatment of humeral shaft fractures. METHODS: the study included 77 patients (41 males, 36 females; mean age 46.38 years; range 18-74 years) with humeral shaft fractures treated with a single 4.5 mm LCP, dual 3.5 mm LCP and IMN between January 2016 and December 2020. Single 4.5 mm LCP (Group A) was applied to 31 (40.3%) patients, dual 3.5 mm LCP (Group B) to 20 (26%) patients and IMN (Group C) to 26 (33.8%) patients. The preoperative and postoperative data of the patients were analyzed from the hospital registry system. A short version of the disabilities of the arm, shoulder and hand (QuickDASH) questionnaire was used to evaluate functional outcomes. RESULTS: as a result of the comparison of the rates of nonunion between the groups, a significantly lower rate of nonunion was observed in group B patients (p=0.027). While the rate of nonunion was 14% in the cases included in the study, no cases of nonunion were encountered in group B. There was no difference between the three groups in terms of demographic data and other postoperative complications. CONCLUSION: dual 3.5 mm LCP method is a suitable alternative to other surgical methods in the treatment of humeral shaft fractures, due to similar functional results and lesser nonunion.
