Does an Additional Antirotation U-Blade (RC) Lagscrew Improve Treatment of AO/OTA (Orthopaedic Trauma Association) 31 A1-3 Fractures With Gamma 3 Nail?

January 15, 2016 updated by: Julian Joestl, Medical University of Vienna

Does an Additional Antirotation U-Blade (RC) Lagscrew Improve Treatment of AO/OTA (Orthopaedic Trauma Association) 31 A1-3 Classified Fractures With Gamma 3 Nail?

The purpose was to evaluate whether the additional use of the Gamma3 ® RC Lag Screw is associated with a reduced cutout rate in patients with OTA/AO 31A1-3 inter-trochanteric fractures.
