Orthopaedics · Bone tumours: Campanacci grade of giant cell tumour

Sample item

A giant cell tumour of the distal radius shows cortical thinning and expansion with a breach of the cortex and extension into soft tissue. Which Campanacci grade is this?

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

The answer and the reasoning

D. Grade III

Campanacci grades giant cell tumours radiologically. Grade I is latent with a well-marginated border and intact cortex, grade II is active with cortical thinning and expansion but no breach, and grade III is aggressive with cortical destruction and soft tissue extension. Higher grades have more local recurrence.

Option by option

  • A. Grade 0

    There is no grade 0 in this system.

  • B. Grade II

    Grade II expands the cortex without breaking it.

  • C. Grade I

    Grade I has intact cortex and a sclerotic rim.

  • D. Grade III (correct)

    Correct. Cortical breach and soft tissue extension indicate grade III.
