Comminuted fractures of the thigh bone are usually treated with surgical internal fixation after the bone is removed, and the fracture heals well enough to grow back. The majority of comminuted thigh fractures require surgical treatment and recovery through debridement and surgery. After the fracture has been set through surgery and then fixed with plate and screws, most of the femur fracture can be completely healed in 3~6 months after surgery. The plate and screws can be taken out at a later date, 1.5~2 years after surgery, and it is recommended to use crutches to protect the fracture for 1~2 months after the plate and screws are taken out to avoid secondary fracture. In most patients, the nail holes after the removal of the plate can be completely healed in 2~3 months after the operation. Comminuted fractures of the thigh bone should be treated promptly after diagnosis to avoid causing adverse effects.
