Computer and experimental analyses of the stress state in the cement hip joint endoprosthesis body [PDF]
Vojnosanitetski Pregled, 2014 Background/Aim. One of the possible complications after implantation of a cement hip-joint endoprosthesis is fracture in the endoprosthesis body. Fractures arise from overload or material fatigue of which an implant is made.

Stress fracture of the femoral neck after Pipkin type IV hip injury [PDF]
Vojnosanitetski Pregled, 2019 Introduction. Hip fractures/dislocations of Pipkin type IV are rare, often accompanied by complications and poor outcome. We describe a complication in the form of a stress fracture of the femoral neck (SFOFN) after the Pipkin type IV fracture ...
