Outcomes of Closed Diaphyseal Humeral Fractures Treated by Dynamic Compression Plate versus Intramedullary Nail

Abstract

Background: Compression plates and intramedullary nails are commonly used devices for stabilizing humeral shaft fractures. Nailing is often associated with postoperative shoulder pain and stiffness due to impingement from prominent implants. Plate fixation may reduce the risk of shoulder problems and the likelihood of reoperation.

Objective: This study aims to compare the outcomes of closed diaphyseal humeral fractures treated with dynamic compression plates versus intramedullary nails.

Methods: A total of 40 patients with closed diaphyseal humeral shaft fractures, reported within two weeks of injury, were included in the study. Clinical examinations and X-rays were utilized for diagnosis. Patients were divided into two groups: Group A received dynamic compression plates, while Group B received intramedullary nails. Postoperative assessments included severity of pain, complications, and hospital stay. The Chi-square test was applied, with a p-value of <0.05 considered significant.

Results: Postoperatively, in the dynamic compression plate group, 50% experienced mild pain, 35% moderate pain, and 15% severe pain. In the intramedullary nail group, 30% had mild pain, 50% moderate pain, and 20% severe pain. Complications were observed in 4 patients in Group A and 7 in Group B. Hospital stays ranged from 1-10 days for 40% of Group A patients and 11-20 days for 60%. For Group B, 55% stayed 1-10 days and 45% stayed 11-20 days.

Conclusion: The management of closed diaphyseal humeral fractures with dynamic compression plates is superior to intramedullary nails, exhibiting lower rates of pain severity and complications.
