Sample item

A child with spastic diplegia has a scissoring gait and tiptoe walking. Which hip complication is most likely?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Progressive hip subluxation and dislocation

Spastic adductors and hip flexors in cerebral palsy produce coxa valga with progressive lateral migration of the femoral head, and subluxation or dislocation. Hip surveillance radiographs allow early soft tissue release or osteotomy.

Option by option

  • A. Septic arthritis

    Septic arthritis is not a feature of cerebral palsy.

  • B. Avascular necrosis only

    Avascular necrosis is not the primary complication.

  • C. Progressive hip subluxation and dislocation (correct)

    Correct. Hip subluxation and dislocation are common with spastic diplegia.

  • D. Coxa valga with no subluxation

    Coxa valga is accompanied by subluxation in severe cases.
