Short versus long intramedullary nails for treatment of intertrochanteric femur fractures (AO 31-A1 and AO 31-A2): a systematic review

Objectives Intramedullary nails are used increasingly in the surgical treatment of intertrochanteric femur fractures (IFFs). However, controversy has developed regarding the length of the nail itself. The purpose of this study is to investigate differences in reoperation rate, as well as operating time, length of hospital stay and 1-year mortality between short and long intramedullary nails in IFF-type AO 31-A1 and AO 31-A2.
