Now-a-days traffic accidents and high–energy injuries are increasingly common. Hip dislocations are classified as high–energy traumas. Femoral head fractures, although not common in orthopedic surgery, are often associated with posterior hip dislocations. Issue of the femoral head fractures was compiled by Pipkin and assigned to I-IV types. Methods of treatment and surgical approaches depend on pattern and type of the fracture. In this paper, we present clinical case of the Pipkin II type femoral head fracture with hip dislocation and ipsilateral transverse patella fracture. We performed an open reduction and internal fixation with four cortical screws via Kocher–Langenbeck approach and tension band wiring.
