Orthopaedics · Dislocations: Bigelow manoeuvre

Sample item

An emergency physician reduces a posterior hip dislocation by applying traction in the line of the deformity, then adducting and internally rotating the flexed hip and finally abducting, externally rotating and extending it. Which manoeuvre is this?

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

The answer and the reasoning

A. Bigelow manoeuvre

Bigelow's manoeuvre uses the intact Y-ligament as a fulcrum. After traction with the hip flexed, adducted and internally rotated, the hip is abducted, externally rotated and extended to lever the head into the acetabulum. Allis and Stimson methods are alternatives, and reduction should be done within 6 hours where possible.

Option by option

  • A. Bigelow manoeuvre (correct)

    Correct. The sequence described is the Bigelow manoeuvre.

  • B. Kocher method

    Kocher's method is a shoulder reduction technique.

  • C. Hippocratic method

    The Hippocratic method is a traction and counter-traction method with the foot in the axilla for the shoulder.

  • D. Stimson gravity method

    The Stimson method uses gravity with the patient prone and the hip flexed over the edge of a table.
