Comparison of Post-operative Functional Outcomes of Intertrochanteric Fractures Treated With Trochanteric Fixation Nail Versus Proximal Femoral Nail.

BACKGROUND

Intertrochanteric femur fractures are common in the elderly and a growing public health concern. Surgical fixation remains the gold standard, with proximal femoral nail (PFN) and trochanteric fixation nail (TFN) being the most commonly used implants. This study compares the functional outcomes and complications of PFN and TFN in the Indian population.

METHODS

A prospective study was conducted over 16 months at Max Super Specialty Hospital, New Delhi, involving 52 skeletally mature patients with intertrochanteric fractures. Patients were divided into two groups: PFN (n=26) and TFN (n=26). Functional outcomes were evaluated using the Harris Hip Score at six months. Pain was assessed using the visual analog scale (VAS) at six weeks and six months. Radiographs were used to assess fracture union and complications such as screw backout, varus collapse, and femoral canal impingement.

RESULTS

No significant differences were found between the groups in terms of age, sex, operative time, or fracture type. The mean operating time was slightly shorter in the TFN group (42.4 min) than in the PFN group (45.7 min), though not statistically significant. Harris Hip Scores, VAS scores, and time to union were similar across groups (p > 0.05). Complication rates were low in both groups, with a slightly lower incidence of screw-related issues and femoral impingement in the TFN group.

CONCLUSION

Both TFN and PFN are effective and reliable options for intertrochanteric fracture fixation. While outcomes are largely comparable, TFN may offer marginal advantages in operative ease and implant-related complications.
