Does the baby need correction for abnormal hip joint angle found during physical examination?

The need for correction of hip joint angle abnormalities found during a baby's physical examination depends on the specific degree of abnormality. Diseases such as hip dysplasia, acetabular dysplasia, and congenital hip dislocation may lead to abnormal angles, usually manifested as limited lower limb movement and asymmetric hip lines. Slight abnormalities in hip joint angle may improve spontaneously with growth and development. Some infants may experience temporary angular deviation due to intrauterine posture or physiological muscle tone differences, manifested as limited abduction but no structural lesions. This type of situation can be promoted through regular ultrasound or X-ray monitoring, combined with daily care such as frog hugging posture and avoiding leggings to facilitate natural recovery. Parents should pay attention to observing the symmetry of bilateral leg patterns and kicking strength, and the interval between rechecks within 6 months should not exceed 3 months. Significant angle abnormalities require medical intervention. When the alpha angle measured by ultrasound is less than 60 degrees or the coverage of the femoral head is less than 50%, it indicates developmental defects in the hip socket. At this point, Pavlik suspenders should be used for positional fixation to promote acetabular shaping by maintaining hip flexion and outward extension. If subluxation still exists after 9 months of age, closed reduction and plaster fixation should be considered. Delayed treatment may lead to sequelae such as claudication and arthritis. Regular imaging evaluations should be conducted during the correction period to avoid compressive skin damage.

It is recommended that parents choose pediatric orthopedic specialty follow-up and develop individualized plans based on Graf classification. During the correction period, keep the skin clean and dry, and check the position of the braces daily. Supplementing with vitamin D promotes bone development and avoids premature weight-bearing walking. Most children who receive early intervention have a good prognosis, and those who complete treatment before the age of 2 can achieve near normal joint function.
