title: [Femoral neck fractures in bicyclists due to clipless pedals].
abstract: Femoral neck fractures in healthy young adults caused by a relatively low-energy trauma are uncommon. The cases are presented of four cyclists, men of 37, 42 (n = 2) and 43 years old, with a femoral neck fracture, in which so called clipless pedals played an important part. The shoes of the cyclist are affixed to these pedals, and the patients had been unable to remove their feet quickly when they fell. They were treated by osteosynthesis using screws, but one of them developed intra-articular infection which eventually necessitated implantation of a total hip prosthesis.
