Functional exercises after hip surgery include these stages: 1, early postoperative plaster pants fixation: ankle dorsiflexion, static contraction of thigh quadriceps, to avoid long-term braking-related muscle atrophy and osteoporosis; 2, because hip incision and reset will cause joint adhesions, plaster fixation will cause joint stiffness, after the removal of plaster pants after surgery (various types of surgery are not exactly the same, generally 6 weeks), you need to start doing hip After removal of the cast (generally 6 weeks), you need to start to restore the range of motion of the hip joint, mainly hip flexion and extension exercises. Encourage the child to initiate activities to improve joint function, such as bending over and touching the toes, putting on socks, and other movements. You can also use parental help or CPM machines to assist with the exercises, but you should be gentle and slow, and avoid forceful, rough and passive exercises. Generally, the recovery is relatively faster for younger children. Since the osteotomy has not yet healed at this stage, standing and weight-bearing (including kneeling) is not yet possible. The hip joint may be mildly swollen during the exercise process, in addition to adjusting the frequency of exercise, you can apply local cool compresses; 3, because the hip joint dislocation itself will have hip joint surrounding muscles (especially the gluteus medius) dysplasia, the surgical operation process will further aggravate the muscle damage. After the operation to see the child’s buttocks often a large and small is the reason. Therefore, the exercise and recovery of the gluteus medius muscle after hip surgery is very important. In general, we recommend the prone position posterior leg raise exercise movement. Let the child lie on his or her back and lift the leg backwards with the knee straight. After the child does not struggle to lift the leg directly, you can change to do the abduction leg lift (lying leg outward skewed knee to lift the leg backwards), or parents give some resistance at the child’s ankle / or hang the appropriate weight at the child’s ankle; 4, after the child’s hip range of motion and muscle strength recovery is about the same, it is generally time to review the film, whether you can stand and walk on the ground is mainly to see the healing of the surgical osteotomy place. The situation. There are differences in the time allowed for weight-bearing after various surgeries, the most common one is about three months after pelvic osteotomy + femoral osteotomy; 5. After the child has fully recovered, still encourage the child to continue to do gluteus medius exercises, just like playing games, which are beneficial to the stability of the soft tissues around the hip joint. Swimming is recommended by orthopedic surgeons because it does not increase the pressure on the hip joint, but it is beneficial to the muscles and cardiorespiratory function of the whole body.
