The main reason for the 87-year-old man to walk normally after surgery for right intertrochanteric femur fracture is due to muscle atrophy and muscle adhesion. Treatment should be directed at the cause of the disease, and the treatment mainly includes physical therapy and rehabilitation training. 1. Muscle atrophy: the elderly right femur intertrochanteric fracture can be due to a long time in bed and treatment, muscle atrophy phenomenon. For patients with postoperative muscle atrophy, physiotherapy can be used to relieve the symptoms. Physiotherapy mainly includes heat therapy, massage, deep microwave, etc., which aims to accelerate blood circulation in the lower limbs and restore normal muscle elasticity. 2. Muscle adhesion: after right inter-rotor fracture, the elderly will suffer from bruising and trauma in the thigh muscles due to bleeding and pulling. The old bruises will lead to muscle adhesion. Treatment requires rehabilitation. This mainly includes extension and flexion of the hip, knee and ankle joints as well as rotational function, passive stretching and active contraction of large muscle groups such as the biceps femoris and quadriceps femoris. If the patient’s symptoms of thigh muscle stretching pain are severe, or if the symptoms continue without improvement, he or she should go to the hospital in time for treatment.
