Early Detection of Developmental Hip Disorders Crucial for Long-Term Health

Early Identification of Developmental Hip Disorders Essential for Long-Term Health

The Cliff News | August 20, 2026

Developmental hip abnormalities, present from birth or arising during development, can affect the normal alignment and stability of the hip joint. Among these, developmental dysplasia of the hip (DDH) is the most prominent.

If these conditions are not diagnosed and treated appropriately in a timely manner, they can lead to severe future problems such as hip pain, difficulty walking, and premature osteoarthritis. Abnormal development of the acetabulum (hip socket) may not provide adequate coverage for the femoral head (the upper end of the thigh bone), with severity ranging from mild shallowness to complete displacement of the femoral head.

In cases of DDH, the acetabulum develops incompletely, resulting in reduced coverage of the femoral head. When this coverage is partially reduced, it is termed subluxation, while complete displacement is considered dislocation. This problem can affect one or both hips.

Key risk factors include female infants, breech presentation (baby's feet first during birth), family history, oligohydramnios (low amniotic fluid), and first pregnancies.

Early Detection Methods in Newborns

Barlow and Ortolani tests are extremely important diagnostic procedures for detecting hip dysplasia in newborns. These tests assess hip instability.

As the infant grows, issues like limited hip abduction, leg length discrepancies, and the Galeazzi sign may appear, indicating this disorder. In older children, limping or a Trendelenburg gait can also signal hip problems.

For young infants whose hip bones are not yet fully developed, ultrasound proves to be an effective screening tool. After approximately 4 to 6 months of age, an AP Pelvis X-ray becomes more useful for understanding the structural status of the hip.

Radiographic evaluation, including analysis of parameters like the acetabular index, Shenton line, lateral center-edge angle, and migration percentage, aids in accurately assessing the hip's condition.

Other Developmental Abnormalities and Their Effects

In addition to acetabular dysplasia, several developmental abnormalities can be observed in the proximal femur. Coxa vara involves a reduced neck-shaft angle, while coxa valga features an increased angle. Both conditions can affect normal hip biomechanics.

Similarly, excessive femoral anteversion can lead to an intoeing gait, while reduced or retroversion can cause the foot to turn outward. In some cases, this can also lead to femoroacetabular impingement (FAI).

The evaluation of hip problems in children should not solely focus on DDH. Other conditions such as Perthes disease, slipped capital femoral epiphysis (SCFE), transient synovitis, developmental coxa vara, and femoroacetabular impingement must also be taken seriously, as their symptoms can often resemble those of DDH.

Long-Term Health and Treatment Options

Untreated developmental hip abnormalities lead to hip instability, labral damage, cartilage degeneration, and ultimately, premature secondary osteoarthritis. Therefore, the treatment approach depends on the child's age, the severity of the problem, the hip's reducibility (how easily the hip can be returned to its correct position), and the structural condition visible on X-ray.

In young infants, a Pavlik harness or other abduction braces may be effective in appropriate cases. If dysplasia persists, closed reduction and, if necessary, a hip spica cast can be used.

In older children, open reduction with pelvic or femur osteotomy may be required, involving surgically cutting and repositioning the bone.

For adolescents and young adults with symptomatic acetabular dysplasia, hip-preservation surgery such as periacetabular osteotomy (PAO) is performed for suitable patients. In cases of severe secondary osteoarthritis, total hip arthroplasty may be the last resort.

It is extremely important not to dismiss hip pain, limping, or recurrent mechanical symptoms in young individuals as mere common ailments. A comprehensive evaluation of acetabular coverage, femoral version, head-neck morphology, labrum, and cartilage is essential.

It is also possible for conditions like DDH and femoroacetabular impingement to coexist, potentially leading to premature hip osteoarthritis. Therefore, timely diagnosis, the use of appropriate imaging techniques, and age-appropriate effective treatment play a crucial role in maintaining hip function and reducing future complications.
