Sample item

Which Delbet type of paediatric femoral neck fracture is the commonest?

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

The answer and the reasoning

B. Type II, transcervical

Delbet types are I transepiphyseal, II transcervical, III cervicotrochanteric and IV intertrochanteric. The transcervical type II is the commonest and carries a high risk of avascular necrosis, so early anatomical reduction and fixation is advised.

Option by option

  • A. Type I, transepiphyseal

    Type I is rare.

  • B. Type II, transcervical (correct)

    Correct. Transcervical fractures are the commonest.

  • C. Type IV, intertrochanteric

    Type IV has the best prognosis but is less frequent.

  • D. Type III, cervicotrochanteric

    Type III is the second most common but less so than type II.
