Abstract
Flexible intramedullary nailing is a common method used to treat pediatric femur fractures. Complication rates can be high, but most complications are considered minor and do not result in additional unplanned surgeries. Proximal nail penetration is a complication that has only been described once before. The penetration may be asymptomatic, but is still best to be avoided. Two cases of proximal nail penetration of the femoral neck region during nail insertion are presented. A review of the literature with regard to complications and suggestions for avoidance of proximal nail penetration is offered.
