Functional Outcome Of Intertrochanteric Fractures Treated By Proximal Femoral Nailing Anti-Rotation-II- A Prospective Study.

Intertrochanteric fracture is one of the most devastating injuries in the elderly.The incidence of these fractures increases with advancing age due to osteoporosis and poor bone quality PFNA-II utilizes a helical blade instead of the conventionally used two screws.The helical blade is believed to provide stability, compression as well as rotational control of the fracture.Theoretically it compacts the bone during insertion into the neck and hence has higher cut out strength as compared to other devices.The differences are that mediolateral angle is reduced from 6 degrees to 5 degrees.Hence there is less chance of implant failure especially in elderly, osteoporotic bones.Thus, PFN Anti-rotation-II is a modification of the conventional PFN which reduces even the minimal complications associated with convectional PFN.
