With the increase in the number of patients with necrosis of the femoral head, this disease has also received attention in life. This disease is very harmful, it is best to early detection and early treatment. The treatment of necrosis of the femoral head depends on treatment in three parts, seven parts depend on nutrition, patients in the treatment at the same time, should pay attention to the daily rehabilitation exercise. Today, we will explain to you the rehabilitation training method of necrosis of the femoral head! First, what are the clinical manifestations of each stage of femoral head necrosis? Phase I clinical manifestations: progressive pain in hip and knee joints, mild limitation of hip joint activities. (pain, lower limb cold, weakness, claudication) Ⅱ clinical manifestations: conscious symptoms of hip pain, persistent progressive hip pain, standing hip pain is severe, serious cases can not walk without crutches. (lower limb cold, pain, joint stiffness, limited movement) Ⅲ clinical manifestations: pain, intermittent claudication, limited joint movement, the affected limb has different degrees of shortening and dysfunction. Stage IV clinical manifestations: pain, dysfunction, stiffness and inability to walk, dislocation or subluxation, limitation of functional activities involving the knee joint. (Appearance of claudication is more obvious, muscle groups are damaged, body temperature is reduced, its internal for hypoxic metabolism, hip joint acidic and sleepy, edema, severe collapse, fragmentation traumatic arthritis). Second, the rehabilitation exercise of necrosis of the femoral head considerations: necrosis of the femoral head in addition to appropriate treatment, appropriate rehabilitation exercise is equally important. Of course, the rehabilitation exercise should be carried out without weight bearing, which not only can effectively promote the repair of the femoral head, but also can prevent muscle atrophy. However, rehabilitation exercise is not the more the better, but must abide by certain principles. 1, rehabilitation exercise must be stabilized after receiving treatment, rehabilitation exercise under the guidance of professional medical personnel, otherwise it may aggravate the condition, in the pre-femoral head necrosis and the development of the period to pay attention to bed rest, less walking, walking in time, but also on crutches, in the control of the condition, before you can carry out rehabilitation exercise. 2, rehabilitation exercise should not be too strenuous, to the extent that the lower limbs are slightly hot and not fatigue, the movement from small to reach, from slow to fast, step by step, can not be rushed, each person’s physical condition is different, the degree of disease is also different, in accordance with their own actual situation for appropriate rehabilitation exercise. 3, exercise process if the bone friction sound, slight pain, are normal reaction, as long as a little rest will ease. But if the pain is severe, you should reduce the number of activities and amplitude. Rehabilitation exercise in the process of pain reaction is very normal, the patient must be under the guidance of the doctor for rehabilitation exercise, not blindly. 4, rehabilitation exercise action can not be too rough, to their own exercise as the main, others to help exercise as a supplement, rehabilitation exercise is mainly to prevent adhesion of flesh and bone, muscle atrophy. Rehabilitation exercise should be from simple to complex, the movement from slow to fast, exercise must have family members beside the escort, to avoid accidents and unnecessary injuries. Third, the exercise method of necrosis of the femoral head: necrosis of the femoral head rehabilitation exercise is very important, can prevent muscle atrophy, is to promote early recovery of the condition of an effective means. Rehabilitation exercise should be automatic, passive as a supplement, from small to large, from small to large, gradually increase, necrosis of the femoral head rehabilitation exercise is important in persistence, only unremitting exercise will see the effect. 1, stomping air lying on the back, hands on the side of the body, double lower limbs alternately flexing the hip, bending the knee, so that the calf hangs in the air, repeated hip flexion-based stomping air movement, amplitude, the number of times gradually increase. 2.Elevation Lie on your back, straighten both lower limbs, put both hands on the side of the body, elevate the affected limbs to a certain limit, and make inward and outward movement, raise and lower the limbs, repeat for 5-10 minutes. 3, hip flexion Lie on your back, keep your feet off the bed, bend your knees and hips as much as possible, put your hands in front of your chest, take the center of your heels as the axis, do abduction and adduction, mainly abduction, and increase the amplitude. 4, hovering supine, both lower limbs straight, hands on the side of the body, the affected limb elevated 45 degrees, stay three seconds, then slowly down, alternating between the two legs. 5, prone rotation supine position, both lower limbs straight, feet and shoulder width, to the heel as the axis, the tips of the feet and lower limbs for internal rotation, external rotation exercise 5-10 minutes. 6.Split leg lying on the back, the affected limbs to the lateral side as much as possible to unfold and then retract, repeated 10-20 times. 7, backward stretching prone, both lower limbs straight, hands on the side of the body, the affected limb backward stretching exercise 5-10 minutes, can be completed by others, amplitude, the number of times gradually increased. 8, squatting Standing, single or two-handed stretching forward to hold on to fixed objects, the body upright, feet apart, and shoulder width, slowly squatting and then pick up, repeated for 3-5 minutes. 9, before and after the swing Standing, single-handed lateral support of the fixed object, single-legged weight and stand, the affected limb forward flexion, backward extension swing 3-5 minutes, alternating between the two legs. Warm tips: necrosis of the femoral head rehabilitation exercise plays an important role in the treatment of necrosis of the femoral head, must adhere to the scientific exercise methods, can not be anxious, can not make themselves too tired.
