The common sequelae of intertrochanteric fracture of femur are: 1, fracture non-union: due to the rich blood flow in the trochanter, the fracture rarely does not heal after fracture, but if the conservative treatment or surgical treatment does not make the fracture end to achieve good stability, and the fracture end is frequently active, and the fracture does not have good healing conditions, the fracture will not be healed, resulting in dysfunctions; 2, fracture deformity healing or internal rotation of the hip: the fracture is treated with conservative treatment such as Traction treatment or surgical fixation, but the position of the fracture end is not good, or the surgery is not well reset, which leads to non-normal shape healing, most commonly seen in the femoral neck stem angle becomes small, leaving the hip endoprosthesis deformity, which often leads to different degrees of functional limitation; 3, delayed nerve injury: may be due to the fracture deformity healing, resulting in long-term nerve pull or fracture of the nerves at the fracture place by the bone crust compression and embedding, which leads to the fracture of the middle and later stages of the progressive nerve symptoms; 4, anomalous nerve: the fracture does not have good conditions for healing, which leads to the fracture non-healing, leading to functional impairment. Neurological symptoms; 4, heterotopic ossification or ossification myositis: after the cut and surgery to restore the internal fixation, the fracture and soft tissue repair form a large amount of fibrous tissue, scar tissue, and even cartilage or bone tissue, and sometimes there will be heterotopic ossification or ossification myositis, which affects the joint activities and causes the dysfunction of the limbs; 5, unstable surgical internal fixation: the patient has osteoporosis, and the internal fixation will be loose, displaced, or dislocated, and the patient will be blindly active and loaded with weights prematurely, and the internal fixation will be loose, dislocated, or damaged. The internal fixation will loosen, dislocate and break, which will cut and destroy the hip joint and cause serious dysfunction, and artificial hip joint replacement will be performed again.
