Background: Several techniques and tools are available for achieving fracture reduction during antegrade intramedullary nailing of femur fractures. Aims: To compare results of femoral shaft fracture treatment with nailing through the greater trochanter to nailing through the piriformis fossa (PF). Materials and Methods: The present pilot project was conducted in a time span of 1-year. The patients admitted with femoral diaphyseal fractures were alternately selected for antegrade nailing through PF group and greater trochanter entry (GTE group) approach. Total number of patient in each group was 15 (n = 15). Results: Complications of nailing: PE group - 6.7% infection, 20% malunion, 20% delayed union, 20% restriction of hip range of motion (ROM), 6.7% restriction of knee ROM, 13.3% limb length discrepancy, 13.3% hardware prominence. GTE group - 13.3% malunion, 13.3% delayed union, 33.3% Restriction of hip ROM, 6.7% restriction of knee ROM, 20% limb length discrepancy, 26.7% hardware prominence. Radiological union time in PE was 12-15 weeks in 5 patients, 16-19 weeks in 8 patients, 20-23 weeks in 1 and >24 weeks in 1 patient. Radiological union time in GTE was 12-15 weeks in 4 patients, 16-19 weeks in 9 patients, 20-23 weeks in 2 patients. Need for dynamization was 20% in the PE group and 13.3% in GTE group. Thoresen's scoring system showed no significant difference between the two groups. Conclusion: Femoral nailing through the greater trochanter with specifically designed nails and with attention to specific techniques for such insertion should be considered a rational alternative to femoral nailing through the PF with the benefit of reduced requirement for fluoroscopy and decreased operative time.
