Internal fixation treatment of femoral fracture is a surgical treatment, mainly through the use of internal fixation devices (such as plates, steel nails, screws, etc.) to fix the fractured bone pieces together to promote fracture healing. Internal fixation is usually applied to femoral shaft fracture, intertrochanteric fracture and other fracture types with good stability. During the procedure, the surgeon exposes the fracture site and then uses internal fixation devices such as plates and nails to hold the broken pieces of bone together. After surgery, patients need rehabilitation training, including early joint activity, muscle strength training, etc., to promote rehabilitation and restore function. The advantage of internal fixation is that it can provide stable fixation, promote the healing of the fracture and reduce the healing time of the fracture. At the same time, the internal fixation device can be removed after the fracture has healed, eliminating the need for further surgery. However, there are some risks and complications in the treatment of internal fixation, such as infection, vascular and nerve damage, and internal fixation loosening. In conclusion, internal fixation of femoral fracture is a common surgical treatment, which is suitable for stable femoral fracture and can promote the healing and functional recovery of fracture. Surgical risks and postoperative rehabilitation plans should be discussed in detail with your doctor before surgery.
