The most common symptom of femoral head necrosis is pain, which is located in the hip joint, proximal thigh and may radiate to the knee. The pain can be caused by inflammatory lesions of necrotic tissue-repair or high pressure within the inflammatory lesion and can manifest as constant pain, resting pain. Femoral head necrosis is a progressive disease and the natural course of femoral head necrosis includes two aspects, namely progressive collapse of the femoral head and secondary osteoarthritis of the hip joint. Since the disease mostly occurs in young adults, the aim of early minimally invasive surgical treatment is to preserve the femoral head as much as possible before collapse and delay the time of artificial joint replacement, in addition to improving clinical symptoms. At the same time, scientific and reasonable functional exercise is of great help to the rehabilitation of femoral head necrosis and should not be neglected in daily life!
So what exercise methods are there?
1, holding objects squatting method.
Single or two hands forward to hold the fixed object, the body upright, feet apart, and shoulder width, slowly squat and then stand up, repeatedly for 3 to 5 minutes.
2, the affected limb swing method.
Single or two-handed forward or lateral extension to hold the fixed object, single foot weighted and standing, the affected limb forward flexion, backward extension, inward and outward swing 3 ~ 5 minutes.
3.Internal and external rotation method.
Stand with hands on the fixed object, single foot slightly forward, foot followed by the ground, for internal rotation and external rotation for 3~5 minutes.
4.Hip flexion method.
The patient is sitting on the edge of the bed or chair, both lower limbs naturally separated, the patient repeatedly made hip flexion movement for 3 ~ 5 minutes.
5.Open method.
The patient is sitting on a chair or stool, the hip, knee and ankle joints are each at an angle of 90°, the feet are separated, and the axis is between the feet, doing double knee abduction and inward movement for 3~5 minutes.
6. Stirrup air flexion and extension method.
Patient supine, hands on the side of the body, both lower limbs alternately flex the hip and knee, so that the lower leg hanging in the air, like pedaling a bicycle movement 5 ~ 10min, to flex the hip joint is the main, the amplitude, the number of times gradually increased.
7, the affected limb swing method.
Take the supine position, straighten both lower limbs, place both hands on the side of the body, raise the straight leg of the affected limb to a certain limit, make inward and outward movement for 5~10 minutes.
8. Internal and external rotation method.
Patients take supine position, both lower limbs are straight, both feet are shoulder-width apart, both hands are placed on the side of the body, with the heel as the axis, both toes and lower limbs for internal rotation and external rotation activities for 5~10 minutes, with the side with severe functional limitation as the main focus.
9.Hip flexion and opening method.
Patients lie in supine position, flex the hip, flex the knee, step on the bed rail with both feet together, take the lower part of both feet as the axis, do the inward and outward knee activities for 5~10 minutes, mainly on the side with severe hip limitation, and gradually increase the amplitude and number of times.
10. Prone open method.
Patients take a prone position, knees shoulder-width apart, lower limbs straight, hands above the chest, then bend the knees 90°, take the front of both knees as the axis, do calf inward and outward activities for 5~10 minutes, mainly on the side with severe hip limitation, with the amplitude and number of times gradually increasing.
Note: Functional exercise should be done after treatment and stabilization of the disease. Functional exercise should be done gradually and should not be rushed.
