The Gamma Nail (TGN) showed longer surgery times, more blood loss, and higher complication rates than the Proximal Femoral Nail Antirotation (PFNA) for intertrochanteric fractures. PFNA is recommended for elderly and osteoporotic patients.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomaterials Science

Background:

  • Intertrochanteric fractures are common, particularly in elderly individuals.
  • Intramedullary fixation is a standard treatment for these fractures.
  • Device selection can impact surgical outcomes and patient recovery.

Purpose of the Study:

  • To compare the efficacy and safety of two intramedullary devices: the Gamma Nail (TGN) and the Proximal Femoral Nail Antirotation (PFNA).
  • To evaluate surgical time, blood loss, and complication rates associated with each device in treating intertrochanteric fractures.

Main Methods:

  • A retrospective study comparing 46 TGN and 51 PFNA implants used between 2006-2007.
  • Clinical and radiological follow-up data were collected.

  • Surgical duration, blood loss, and complication incidence were analyzed.

    • Main Results:

    • The TGN group had significantly longer operative times (62 min vs. 45 min, p=0.04) and greater blood loss (285 ml vs. 226 ml, p=0.03) compared to the PFNA group.
    • A higher rate of complications was observed in the TGN group (p=0.01).
    • Complications in the TGN group were linked to longer operative times and increased blood loss, potentially due to reaming, and were more frequent in elderly patients.

    Conclusions:

    • The Proximal Femoral Nail Antirotation (PFNA) is recommended for elderly and osteoporotic patients undergoing treatment for intertrochanteric fractures.
    • The Gamma Nail (TGN) may be more suitable for severely displaced fractures in patients with better bone density.
    • Device choice should consider patient-specific factors like age, bone quality, and fracture pattern.
