Internal fixation of humeral shaft fractures using a dynamic compression plate: A prospective study

Fractures of the humeral shaft present a challenge due to their unique anatomical and biomechanical characteristics. Fixation with a dynamic compression plate is a widely adopted technique for the surgical management of these fractures, aiming to achieve stable fixation and promote early mobilisation. This study aimed to evaluate the clinical and functional outcomes of dynamic compression plate fixation in humeral shaft fractures. This prospective study included 40 patients with displaced humeral shaft fractures, including Grade I and II open fractures. Preoperative assessments comprised clinical examinations and radiographic evaluations. Surgical fixation was performed using a dynamic compression plate, and postoperative follow-up was conducted at 2 weeks, 6 weeks, 3 months, and 6 months. Functional outcomes were assessed using the Modified Stewart & Hundley classification, and statistical analysis was carried out. The study cohort had a mean age of 32.64 years (±4.77) and was predominantly male (65%). The most common cause of injury was road traffic accidents (55%). Type A fractures were the most frequent (42.5%), with 70% involving the right upper limb. The mean time to union was 4.58 ± 1.06 months. At 6 months, 10 patients had excellent outcomes, 21 had good, 8 had fair, and 1 had a poor outcome (p < 0.0001). Preoperative complications included multiple injuries. Postoperative complications were minimal, with only one case of malunion reported. The findings suggest that dynamic compression plate fixation is an effective method for the management of humeral shaft fractures, demonstrating significant improvements in alignment and functional outcomes, with low complication rates and favourable union times. These results support the reliability of dynamic compression plating in optimising treatment approaches and improving patient outcomes
