Congenital hip abduction contracture and pelvic tilt

Introduction to congenital hip abduction contraction and pelvic tilt Congenital hip abduction contraction and pelvic tilt are more common in clinical practice, and the incidence is higher than congenital dislocation of the hip, but it is often overlooked because of mild symptoms. basic knowledge The proportion of illness: 0.002% Susceptible people: young children Mode of infection: non-infectious Complications: hip dislocation

Congenital hip abduction contraction and cause of pelvic tilt

(1) Causes of the disease

Due to the abnormal position of the fetus in the uterus, the hip abductor muscle contracture.

(two) pathogenesis

Due to abnormal position in the uterus, the hip joint has been in the outreach position, the gluteus medius and the lateral part of the joint capsule are contracted, the gluteus maximus and the external rotator muscles have different degrees of contracture, acetabular development and ossification delay, contralateral hip Joints often have a subluxation.

Congenital hip abduction contraction and pelvic tilt prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Congenital hip abduction contraction and pelvic tilt complications Complications of hip dislocation

It is difficult to kneel.

Congenital hip abduction contraction and pelvic tilt symptoms Common symptoms Funnel pelvic squat difficulty Spinal lesions Pelvic malformation gait instability Spine scoliosis children drag and drop

Most of the children were in a frog-like position, the lower limbs of the affected side were in the outreach position, and the activities were less. When the pelvis was fixed, the hips could not be adducted, the internal rotation, the affected side of the anterior superior iliac spine, the sputum was lower than the healthy side, and the bilateral pleats were Asymmetry, when the lower limbs are close together, the contralateral pelvis is upward, the affected side pelvis sinks, the lumbar vertebra bends to the healthy side, and the convex side is convex to the affected side. Only when the affected limb is in vitro, the pelvis can be at the normal level, and the spine is in line. After the age increases, he walks awkwardly and has a lap-like gait.

Congenital hip abduction contraction and pelvic tilt examination

The hip anterior radiograph was taken at a 45° abduction, and the ossification delay of the acetabular apex was observed. This was due to the hip abduction deformity after the hip abduction, and the femoral head on the adductor side had a central pressure on the acetabulum. Less, sometimes subluxation may occur on the adductor side.

Diagnosis and diagnosis of congenital hip abduction contracture and pelvic tilt

Diagnosis based on symptoms and signs is not difficult.

Similar to congenital dislocation of the hip, attention should be paid to the identification. Ortolani and Barlow tests are positive for the children with congenital dislocation of the hip and the Ober test is negative. The Ortolani and Barlow tests are negative and the Ober test is positive. The Ober test: the child is lying on the side. The affected side is on the upper side, the contralateral hip and the knee are flexed. The examiner stands behind the child, fixes the pelvis in one hand, and holds the upper side of the affected side in one hand, so that the hip and knee are fully abducted at the 90° flexion position, and the lower limb is made. Over-extension and adduction of the thigh, if the lower limb can be attached to the bed is normal (negative), if not, it is abnormal (positive), the degree of abduction maintained at this time can indicate the degree of contracture, the disease causes pelvic tilt, the spine Compensatory lateral curvature, so often associated with congenital scoliosis and hemivertebra, the latter hip incontinence, and X-ray examination can rule out congenital spinal deformity.
