3066 consecutive Gamma Nails. 12 years experience at a single centre

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomedical Engineering

Background:

• The Gamma Nail is a widely used implant for trochanteric hip fracture fixation since 1988.
• Concerns exist regarding its complication rates, particularly femoral shaft fractures.
• This study evaluates the Gamma Nail's performance over a 12-year period using a large patient database.

Purpose of the Study:

• To assess the complication rate of Gamma Nail fixation for trochanteric hip fractures.
• To evaluate the incidence of specific complications, including femoral shaft fractures.
• To determine the overall safety and efficacy of the Gamma Nail in this patient population.

Main Methods:

• Retrospective analysis of 3066 consecutive patients treated with Gamma Nails for trochanteric fractures (1990-2002).
• Data collection included epidemiological information, intraoperative and postoperative complications, and patient outcomes.
• Radiographic assessment was performed by a single reviewer.

Main Results:

• A low overall complication rate was observed: 4.5% intraoperative and 6.2% postoperative complications.
• The most frequent mechanical complication was lag screw cut-out (1.85%).
• Postoperative femoral shaft fractures occurred in only 0.6% of patients, with other complications at 3.7%.

Conclusions:

• Gamma Nail fixation for trochanteric hip fractures is a safe procedure with a low complication profile.
• The study demonstrates a particularly low rate of femoral shaft fractures.
• Adherence to proper surgical technique is likely key to achieving these favorable outcomes.
