Splitting of the proximal femur with a new femoral nail.

We present a case of a 19-year-old woman with a closed diaphyseal femur fracture and who had fixation of the fracture using a newer lateral entry nail, which resulted in an intraoperative proximal femur fracture. The patient underwent revision the following day and subsequently returned to regular activity without signs of implant failure or loss of reduction at latest follow-up. Caution should be exercised with the use of new implants that require a change in customary technique. In addition, some concern must be raised by the amount of offset from the top of this particular nail to its long axis.
