Complications following Treatment of Trochanteric Fractures with the Gamma3 Nail: Is the Latest Version of Gamma Nail Superior to Its Predecessor?

Abstract EN

Gamma nail is a cephalomedullary implant that was developed for the treatment of pertrochanteric hip fractures and has been successfully used for over 20 years.

During this period, modifications of design and instrumentation have occurred to combat the intra- and postoperative complications that were associated with the use of early designs.

The purpose of this study was to compare the complications observed with the use of the Gamma3 nail (G3N) with those seen following use of the previous trochanteric gamma nail (TGN).

This study prospectively recorded the intra- and postoperative complications of 175 patients treated with the Gamma3 nail and compared them with those of a historical cohort of 192 patients treated with the trochanteric gamma nail.

We encountered less intra- and postoperative complications with the use of Gamma3 nail.

Femoral fractures and lag screw cutout were significantly lower.

The reoperation rate was significantly higher in the TGN group.

Gamma3 nail has proved to be a safe and efficient implant for the treatment of pertrochanteric fractures.

The improvement of the biomechanical characteristics has led to a significant decrease in complication rates, demonstrating superiority over its predecessor.
