Orthopaedics · Paediatric: DDH at 8 months

Sample item

An 8-month-old infant is diagnosed with a dislocated hip. Which is the usual treatment?

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

The answer and the reasoning

A. Closed reduction under anaesthesia and hip spica, with arthrogram

Between 6 and 18 months, the Pavlik harness is less successful, and closed reduction under general anaesthesia followed by spica cast immobilisation is the standard. Open reduction is used if closed reduction fails or is not concentric.

Option by option

  • A. Closed reduction under anaesthesia and hip spica, with arthrogram (correct)

    Correct. Closed reduction and spica is standard at this age.

  • B. Pavlik harness with no other intervention

    Harness treatment tends to fail after 6 months.

  • C. Observation only

    Untreated dislocation leads to a permanent deformity.

  • D. Total hip replacement

    Hip replacement is not used in infants.
