    Study Notes

    Musculoskeletal Tumors

    Periosteal Reactions

    • Onion-skin (Ewing's sarcoma): more malignant
    • Sunburst reaction (osteosarcoma): more malignant
    • Codman's triangle: a triangle of reactive bone formation found at the proximal and distal extremes of the elevated periosteum
    • Solid sunburst: less malignant
    • Onion-peel (Ewing's sarcoma): more malignant

    Four Questions of Enneking

    • What is in the lesion?
      • Clues: bone/calcific soft tissue component radiolucent/ground glass
      • Matrix: osteoid/forming process, chondroid/stippled calcification, myxoid/cartilaginous
    • Where is the lesion?
      • Location: epiphysis, metaphysis, diaphysis
    • What is the biologic activity?
      • Endosteal and periosteal response: smooth periosteum (benign process), onion-skin (Ewing's sarcoma), sunburst reaction (osteosarcoma), Codman's triangle
    • What is the extent of the lesion?

    Biopsy

    • Indications: diagnosis of musculoskeletal tumors
    • Techniques: fine needle aspiration (FNA), core needle biopsy
    • Considerations: appropriate staging studies, local anesthesia, ultrasonography, fluoroscopy, computed tomography (CT), and magnetic resonance imaging (MRI)

    Limb Salvage Versus Amputation

    • Considerations: postoperative function, local control, and quality of life
    • Limb salvage surgery: preferred for tumors in the proximal aspect of an extremity
    • Amputation: usually provides better postoperative function and reduced risk of recurrence for tumors located in the distal leg

    Rotationplasty

    • Solution for disfiguring surgical resections of lower limb sarcomas
