A Prospective Study Examining the Clinical and Functional Outcomes of Adults with Proximal Humerus Fractures Treated using a Locking Compression Plate (LCP)

Abstract

Background: Proximal humerus fractures constitute a common orthopedic injury requiring surgical intervention to restore anatomy and
function. Locking compression plates (LCP) have gained popularity due to their stability and suitability.
Aim: To evaluate the clinical and functional outcomes of adult patients with proximal humerus fractures treated using locking compression
plates at a tertiary care referral center in Bihar.
Methodology: This prospective observational study included 36 randomly selected adult patients with displaced proximal humerus fractures
managed with open reduction and internal fixation using LCP. Patients were followed for a minimum of 12 months. Clinical assessment included
pain evaluation using the visual analog scale, shoulder range of motion, and functional outcome using the Constant–Murley score. Radiological
union and postoperative complications were also recorded.
Results: The mean age of patients was 46.8 years, with male predominance. Road traffic accidents were the most common mode of injury.
Radiological union was achieved in all patients, with a mean union time of 12.3 weeks. The mean Constant–Murley score at final follow-up was
76.4. Excellent to good functional outcomes were observed in 72.2% of patients. Complications occurred in 16.7% of cases. Better outcomes
were observed in two- and three-part fractures compared to four-part fractures.
Conclusion: Locking compression plate fixation is an effective and reliable modality for managing displaced proximal humerus fractures in
adults, providing good functional outcomes with acceptable complication rates when combined with proper surgical technique and rehabilitation.
