Impending pathologic fractures from metastatic malignancy: evaluation and management.

K D Harrington

    Instructional Course Lectures
    |January 1, 1986
    PubMed
    Summary

    Long bone metastases pose a fracture risk when over 50% of cortical bone is destroyed or pain persists. Prophylactic internal fixation, augmented with methylmethacrylate, is recommended for high-risk lesions to prevent secondary fractures.

    Area of Science:

    • Orthopedic Oncology
    • Skeletal Metastasis Research

    Background:

    • Metastatic bone disease frequently leads to pathologic fractures.
    • Lytic and blastic lesions compromise bone integrity, increasing fracture risk.

    Purpose of the Study:

    • To identify risk factors for pathologic fractures in long bone metastases.
    • To recommend optimal management strategies for preventing fractures in these patients.

    Main Methods:

    • Review of clinical criteria for fracture risk assessment in bone metastases.
    • Evaluation of prophylactic internal fixation techniques for metastatic lesions.

    Main Results:

    • Fracture risk increases with >50% cortical destruction or persistent weight-bearing pain.
    • Proximal femur lesions >2.5 cm or with lesser trochanter avulsion are high-risk.
    • Prophylactic fixation with methylmethacrylate improves outcomes.

    Conclusions:

    • Aggressive prophylactic internal fixation is crucial for high-risk bone metastases.
    • Augmenting fixation with methylmethacrylate enhances stability and radiotherapy efficacy.
    • Early intervention prevents secondary fractures and improves bone healing potential.
