Approximately 7% of children with which condition also have DDH?

• A. Osteomyelitis
• B. Torticollis
• C. Legg Calve Perthes disease
• D. Idiopathic scoliosis

Answer: (B)

The correct answer is torticollis. In children, torticollis, which is characterized by a twisting of the neck and unusual head position, has been associated with developmental dysplasia of the hip (DDH). Studies indicate that around 7% of children diagnosed with torticollis also present with DDH. The relationship is thought to stem from postural factors and the influence of certain positions during early developmental stages.

In contrast, osteomyelitis typically does not have a direct association with DDH. This condition primarily affects the bone and is caused by infection rather than developmental issues relating to joint formation. Legg-Calve-Perthes disease is a condition affecting the hip joint in children, but its association with DDH is not as evident as it is with torticollis. Similarly, idiopathic scoliosis primarily involves curvature of the spine and does not commonly intersect with disorders of hip development like DDH. Understanding these relationships helps clarify the connections between various pediatric orthopedic conditions.
