The effect of calcar femoral neck plating on vascularity of the femoral head and neck

Bone & Joint Open, 2021
Aims: Surgical treatment of young femoral neck fractures often requires an open approach to achieve an anatomical reduction. The application of a calcar plate has recently been described to aid in femoral neck fracture reduction and to augment fixation ...

Evaluation of a pig femoral head osteonecrosis model

Journal of Orthopaedic Surgery and Research, 2010
Background A major cause of osteonecrosis of the femoral head is interruption of a blood supply to the proximal femur. In order to evaluate blood circulation and pathogenetic alterations, a pig femoral head osteonecrosis model was examined to address ...
