iliotibial band cut

Normally, the pelvis remains horizontal, and the pelvis is tilted only when the gluteal muscle is paralyzed or the side of the leg is short. The iliac crest and hip abductor contracture can also cause pelvic tilt. Generally, the light pelvis is inclined, and the horizontal line of the highest point of the two ridges is 3 to 4 cm; the medium pelvis is inclined, and the horizontal lines of the two rafts are 5 to 6 cm or more apart. According to the light, medium and heavy clinical treatments, the different treatment methods are adopted: the light type is only the hip abduction deformity caused by the contracture of the hip, and the walking is obvious when walking. The early cutting of the bundle can be corrected. The mid-type hip abduction contracture deformity pelvic tilt is obvious, although the iliac crest cut can not be completely corrected, the upper end of the femur wedge-shaped adduction osteotomy. If there is hip dislocation on the contralateral side, hip capping is required. In addition to one side hip abduction deformity, the contralateral hip joint also has subluxation and short limb deformity, and the affected limb cannot touch the ground. Therefore, in addition to correcting hip dislocation and correcting short limb deformity, the contralateral balance is corrected, and the short limbs are corrected. The pelvis can basically reach symmetry to restore the balance of the lever, which is beneficial to improve the weight-bearing function of the lower limb. On the dislocation side, the short limbs are severe, and the tibia and femur are extended at the same time, or the acetabular cap is covered with the trochanter for osteotomy and bone graft extension. The iliotibectomy is used for the treatment of pelvic tilt hip deformities. Treatment of diseases: developmental pelvic abnormalities, congenital hip abduction contracture and pelvic tilt Indication This is suitable for: 1. For patients with light pelvic tilt, aged 13 to 14 years old. 2. Pelvic tilt caused by tendon contracture. Contraindications Non-twisted contracture compensatory pelvic tilt. Preoperative preparation Preoperative pelvic anterior radiographs (intrahip hips) were used to determine the degree of hip abduction and the degree of iliac crest contraction as an intraoperative reference. Surgical procedure Incision The longitudinal incision of the large trochanter was taken to cut the skin, subcutaneous tissue and deep fascia. 2. Cut off the bundle Peeling the deep fascia layer on the outer side of the large trochanter, you can see that the dense and thick grayish white and shiny deep fascial thickening part is the iliac crest, which is cut obliquely in the plane of the large trochanter, and the lower limbs are as far as possible. If the internal line is not able to reach the midline of the pelvis, the tensioned fascia should be cut off. The gluteus medius should be peeled off. If necessary, the lateral muscle interval should be removed and the gluteus maximus should be short. It should be extended when the contraction is obvious. Except for the expansion of the exhibition, the contraction can be adducted. When the soft tissue release is not up to the purpose of adduction, a trochanteric adduction osteotomy is required.
