The Gamma nail was designed to treat unstable intertrochanteric and subtrochanteric fractures.
The device was developed after cadaver studies and has been used clinically since 1985.
The Gamma nail transmits weight closer to the calcar than does the dynamic hip screw and it has greater mechanical strength.
A semi-closed operative technique is used, with an average duration of operation of 35 minutes and little blood loss. Distal locking screws can be used to maintain rotational stability.
