Orthopaedics · Bone tumours: Mirels score

Sample item

A Mirels score is used to estimate what in a patient with a metastatic lesion of a long bone?

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

The answer and the reasoning

D. Risk of impending pathological fracture, with prophylactic fixation advised at 9 or more

The Mirels score assigns points for site, pain, lesion type (lytic or blastic) and size relative to the cortex. A total of 9 or more suggests a high fracture risk and prophylactic fixation, while 7 or less can be observed with radiotherapy.

Option by option

  • A. Extent of lymph node spread

    Nodal spread is not assessed.

  • B. Prognosis for survival

    Survival is estimated using other scores such as the Tokuhashi score for spinal disease.

  • C. Sensitivity to chemotherapy

    Chemosensitivity is not assessed.

  • D. Risk of impending pathological fracture, with prophylactic fixation advised at 9 or more (correct)

    Correct. The score predicts fracture risk to guide prophylactic fixation.
