Comparative result of cannulated versus non-cannulated cancellous screw fixation in fracture neck of femur

Abstract

Background: Cancellous screw fixation is treatment of choice for the management of fracture neck of femur in adults. Many types of screws are available including cannulated and non-cannulated. Both have their advantages and disadvantages. Hence we conducted the study to compare result of cannulated versus non-cannulated screw fixation in terms of intra-operative surgical advantage and post-operative results. Objectives 1. To compare result of cannulated versus non-cannulated cancellous screw fixation in fracture neck of femur in adults. 2. To study intra-operative surgical advantage of cannulated over non-cannulated cancellous screw fixation. Patients and Methods: 50 consecutive adult patients ranging from 20-50 years of age those suffering from fracture neck of femur were treated by cannulated and non-cannulated cancellous screw fixation. The study was carried out to compare results of cannulated and non-cannulated cancellous screw fixation for intracapsular fracture neck of femur in young adults. Results: Study conducted on 50 patients of both sex and age between 20 yrs and 50 yrs within the period of 2 years those suffering from fracture neck of femur. Alternate consecutive patients were treated by cannulated and non-cannulated cancellous screw fixation. Data regarding operative time, radiation exposure and average blood loss was collected. Follow up was done at 6 weeks, 3 months, 6 months and 9 months and Modified Harris Hip Scoring (MHHS) and complications were noted. Data was tabulated and statistically analysed. Conclusions: Our study showed that cannulated screw fixation has intra-operative advantage over non-cannulated cancellous screw fixation in terms of operative timing, radiation exposure and average blood loss but there was no advantage in terms of complications and post-operative results.
