Abstract

Background: This study was carried out to study the short term functional outcome of proximal femoral nail
antirotation-II (PFNA-II) in the treatment of unstable intertrochanteric fractures.
Materials and Methods: This prospective study includes 20 cases of unstable intertrochanteric fractures in the age group between 55-94 years. The patients included in the study underwent fixation of intertrochanteric fractures using PFNA-II. The study was conducted in the department of Orthopaedics in an advanced trauma centre in Kerala between August 2018 and June 2019. Patients were followed up and assessed clinically and radiologically at regular intervals at 6 weeks, 3 months and 6 months. Functional score was assessed using Oxford Hip Score and Harris Hip Score.
Results: 20 patients were followed up for a period of 6 months. The minimum and maximum age was 55 and 95 years respectively. Majority of the fractures were fell into AO A2.2( 45.0%). The average OT time was 58.75 minutes with standard deviation 21.82. The average blood loss was minimal ( 124.5 ml). 85% cases could achieve good reduction. Good results were achieved in 75% (n=15) and Excellent results in 20% (n=4) cases according to Harris hip score. There was a significant relationship between Oxford hip score and fracture reduction (p-value is less than 0.05). There was a significant progress in Oxford hip score and Harris hip score 3 month and 6 months. No cases of cut out or breakage of the implant were noted during the study period. There was no major complication or mortality noted during the follow up period.
Conclusion: PFNA-II is ideal implant for fixation of unstable intertrochanteric fractures in elderly patients with less operative time, low complication rate and with a good clinical outcome. However it is important to follow proper
operative technique in order to attain fracture stability and to avoid major complications.
