Abstract :

OBJECTIVES: To study Dynamic Hip Screw (DHS) and proximal femur nail (PFN) in treatment of peritrochantric extracapsular femoral fractures. MATERIAL AND METHODS: Between Aug. 2003 to Aug, 2008, 90 cases of intertrochantric fractures studied prospectively. 45 cases were treated with PFN and 45 cases with DHS. Follow up period of 12 months. Both groups were compared in terms of amount of intra-operative blood loss, duration of surgery, intra-operative radiological exposure. Postoperative complications such as back out of implant, bending or eaking of implant, delayed union or non-union. At end of 1 year functional outcome was determined using Hip Harris score. RESULTS: DHS require longer duration of surgery with more blood loss. Intra-operative radiological exposure required was higher in PFN group. There was no significant difference in the non ambulatory period postoperatively. There was no significant difference in fracture union time. There was single case of non-union in PFN group while none patient in DHS group had non-union. Functional recovery was essentially same in both groups at end of 1 year. CONCLUSION: PFN offers a less invasive surgical technique with less blood loss and less duration of surgery compared to DHS. Rest outcome parameters remain the same.
