With a proximal femur fracture, the knee is immobile after external cast immobilization. Common extremity fractures with external cast fixation require super-adjacent joint immobilization to reduce micromotion of the fracture break.
Fractures of the proximal femur are most often caused by great rotational and axial violence. Treatment can be generally categorized into three types, closed reduction intramedullary nailing internal fixation, incised reduction plate internal fixation, and external fixation in plaster after manipulative reduction.
After external fixation of proximal femur fracture with plaster, the knee and hip joints should be immobilized to avoid the movement of the fracture broken end, at this time, the knee joint is not movable.
After external fixation with plaster, you should lie flat on the bed, do active contraction exercise of lower limb muscles, do ankle dorsal extension, plantarflexion activities and ankle pump functional exercise to prevent lower limb venous thrombosis.
After the proximal femur fracture plaster fixation, it is recommended to follow the doctor’s instructions for treatment, regular review, and good bedside care to avoid adverse consequences.
