OUTCOME OF HUMERUS SHAFT FRACTURES IN ADULTS TREATED BY DYNAMIC COMPRESSION PLATE IN MARDAN MEDICAL COMPLEX

Background: Humerus shaft fractures constitute approximately 3% of all fractures and are commonly managed through surgical or conservative methods depending on fracture complexity and patient condition. Dynamic compression plating (DCP) is widely regarded as a reliable surgical option, promoting union and functional recovery while minimizing complications. Despite its effectiveness, limited regional data is available to guide clinical decision-making. This study aims to evaluate the functional outcomes of DCP in the treatment of humerus shaft fractures at Mardan Medical Complex. Objective: To determine the functional outcomes of humerus shaft fractures in adults treated with dynamic compression plating. Methods: This descriptive case series was conducted at Mardan Medical Complex from June 22, 2021, to December 22, 2021. A total of 139 patients aged 18–70 years, with humerus shaft fractures presenting within 10 days of injury, were included. Patients with upper or lower humerus fractures, segmental fractures, or prior open fractures were excluded. All procedures were performed using DCP, and functional outcomes were assessed using the DASH score on the 30th postoperative day. Data on demographic characteristics, injury mechanisms, and outcomes were analyzed. Results: The mean age of the 139 patients was 32.86±13.55 years. Of these, 72.7% were male and 58.3% sustained fractures due to road traffic accidents. Functional outcomes revealed excellent results in 20.9% (n=29), good outcomes in 61.9% (n=86), fair outcomes in 15.1% (n=21), and poor outcomes in 2.2% (n=3). Middle third fractures accounted for 59% of cases, followed by distal and proximal fractures at 24.5% and 16.5%, respectively. Conclusion: Dynamic compression plating is an effective surgical technique for managing humerus shaft fractures, achieving excellent to good outcomes in the majority of cases. The findings support DCP as a preferred treatment option for optimizing functional recovery in these fractures.
