Frequency of Radial Nerve Injury in Management of Mid Shaft of Humerus Fracture with Dynamic Compression Plate on Anterolateral with Anteromedial Surface Through Henry Approach

Abstract

Objective: The objective of this study was to compare the frequency of radial nerve injury in management of mid shaft of humerus fracture with dynamic compression plate on anterolateral with anteromedial surface through henry approach. Study Design: Randomized controlled trial. Settings: Orthopedic unit, DHQ Hospital, Faisalabad. Duration: During 01-08-17 to 31-01-2018. Methodology: Patients were enrolled in the study through outpatient department in case of non-union humerus after conservative management and through Emergency department after history of trauma and fracture shaft of humerus. Patients were divided into Group A and Group B using computer generated random number table. Patients in Group A having plate applied on anterolateral surface by surgeon1. Patients in Group B having plate applied on anteromedial surface by surgeon. 2 Information was collected by myself and comprised age, sex, address, contact number and injury to radial nerve as determined by clinical examination on 1st postop day. All the information was entered in a standardized Performa by Principal Investigator. Results: On comparison of radial nerve injury in management of mid shaft of humerus fracture with dynamic compression plate on anterolateral with anteromedial surface through henry approach was 20%(n=7) in Group-A cases and 2.86%(n=1) in Group-B cases had radial nerve injury, p value was 0.02. Conclusion: We concluded that the frequency of radial nerve injury is significantly lower in anteromedial plating when compared with anterolateral plating for fracture shaft of humerus using henry approach
