Anterior Bridge Plating for Humeral Shaft Fractures: A Single-Arm Interventional Study

Abstract

Background: Humeral shaft fractures represent a significant portion of upper extremity injuries. Treatment options range from conservative methods to surgical interventions. Anterior bridge plating, a minimally invasive surgical technique, has gained attention for its potential to provide stable fixation while minimizing soft tissue disruption.

Methods: A single-arm interventional study was conducted at Gulbarga Institute of Medical Sciences, Kalaburagi, from June 2021 to July 2024. Twenty patients with isolated diaphyseal humerus fractures were treated using anterior bridge plating. Functional outcomes were assessed using the Constant score for shoulder function and the Mayo Elbow Performance Score (MEPS) for elbow function. Radiological union time and associated complications were also evaluated.

Results: The study included 14 males and 6 females with a mean age of 51.6 years. The majority of fractures resulted from road traffic accidents (55%) and were left-sided (65%). The mean radiological time to union was 25.6 weeks. Functional assessment revealed a mean Constant score of 84.8, indicating good shoulder function, and excellent elbow function in 76.5% of patients based on MEPS. Three cases (15%) developed atrophic non-union, and four patients exhibited moderate shoulder stiffness, which improved with physiotherapy.

Conclusion: Anterior bridge plating for humeral shaft fractures demonstrates satisfactory functional outcomes. The technique offers stable fixation while preserving soft tissue integrity, making it a viable option for managing diaphyseal humerus fractures.
