Comparison of the functional outcome of DHS versus cannulated cancellous screws in pauwels type II and III fracture neck femur in young adults

Abstract

Fracture neck of femur remains the unsolved fracture even in modern orthopaedics. It is an enigma to orthopaedic surgeons and curse for an individual with complications like avascular necrosis and nonunion. No clear difference exists with regards to the clinical results of patients treated with Cannulated screws or Dynamic hip screw fixation. 43 patients with fracture neck of femur were treated with either multiple cannulated cancellous screws (CCS) or dynamic hip screw (DHS) at Department of Orthopaedics, Hamidia hospital, Bhopal. Patients were called for follow up radiologically and clinical examination post operatively. Functional results were calculated with Modified Merle d’aubigne and postel method. Statistical analysis was done using p value.Fracture type, anatomical reduction and proper implant selection are the most important factor affecting the outcome of management of fracture neck femur. Patients treated with DHS had better Modified Merle d’aubigne score and earlier union. Average blood loss and mean operating time was higher in patients fixed with DHS. Dynamic Hip Screw (DHS) is a better implant in management of fracture neck femur in young adults in pauwels type II and III but complication rate does not depend on implant selection.
