Comparative evaluation of efficacy two screw and single helical screw in Proximal femoral nailing in patients with intertrochanteric fractures of femur
Satish Chaudhary

Background: Intertrochanteric fractures are defined as fractures of proximal part of femur located between lesser and greater trochanter. Different versions of Proximal femoral nail (PFN) have in common a smaller diameter proximal nail portion (13 to 15 mm), two lag screws into the head and neck of various diameters, and long and short nail lengths Proximal femoral nail (PFN) was developed combining the features of an unreamed intramedullary femoral nail with a sliding load bearing, 2 femoral neck screws. Hence; under the light of above mentioned data, the present study was undertaken for assessing and comparing the efficacy of two screw PFN and single helical screw PFN in patients with intertrochanteric fractures of femur. Materials & methods: A total of 40 cases of intertrochanteric fractures of skeletally mature adults were enrolled. All the patients were broadly divided into two study groups as follows: Group A: Patients treated with two screw PFN, Group B: Patients treated with single helical screw PFN. Blood samples were obtained and complete hematological and biochemical examination of all the patients was carried out. Clinical examination along with radiographic assessment of all the patients was done. All the patients were treated according to their respective study groups. Functional outcome and Harris hip score was assessed by analyzing the palmer and parker score on follow-up. Results: Significant results were obtained while comparing the mean duration of procedure among subject of both the study groups. Significant results were obtained while comparing the mean time for partial weight bearing among subject of both the study groups. Mean time required for fracture to unite among subjects of group A and group B was found to be 89.5 days and 88.4 days respectively. Non-significant results were obtained while comparing the mean time for partial weight bearing among subject of both the study groups. Non-significant results were obtained while comparing the palmer and parker score and Harris hip score at final 6 months follow-up among subjects of the two study groups. Conclusion: After occurrence of fracture union, functional outcomes are similar irrespective of the type of implant used Key words: Screw, Proximal femoral nail, Femur.
