Anatomy · Lower limb: ischial apophysis

Sample item

A 15-year-old sprinter feels a sudden tearing pain in the buttock on starting a race. X-ray shows avulsion of the ischial tuberosity. Which muscle group was responsible?

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

The answer and the reasoning

C. Hamstrings

The hamstrings arise from the ischial tuberosity. In adolescents the apophysis fuses late, so a sudden forceful contraction in sprinting can avulse it.

Option by option

  • A. Gluteus maximus

    This muscle arises from the ilium and sacrum and not from the ischial tuberosity.

  • B. Iliopsoas

    This muscle inserts on the lesser trochanter and does not arise from the ischial tuberosity.

  • C. Hamstrings (correct)

    Correct. The hamstring origin from the ischial tuberosity is avulsed.

  • D. Quadriceps

    Only the rectus femoris arises from the pelvis in this group, and from the anterior inferior iliac spine.
