Pathologic fracture of bone at site of neoplasm

Last edited: 4/22/2026

Overview

Pathologic fractures occur when bone weakened by neoplastic processes fails under normal stress, often complicating the management of underlying malignancies such as osteosarcoma, myeloma, and metastatic cancers 1.

Diagnosis

  • Imaging studies (X-ray, CT, MRI) essential for identifying bone lesions and assessing fracture risk 1.
  • Biopsy may be required to confirm neoplastic etiology 1.
  • Bone scan or PET-CT can help stage disease and evaluate extent of bone involvement 1.

    • Management

  • Surgical stabilization: Often necessary for definitive treatment, including internal fixation or prosthetic replacement 1.
  • Neoadjuvant/adjuvant therapy: Chemotherapy and radiation therapy tailored to the primary neoplasm to control disease progression 1.
  • Pain management: Multimodal analgesia to address acute and chronic pain 1.
  • Supportive care: Focus on nutritional support, infection prophylaxis, and management of complications 1.

    • Special Populations

  • Elderly: Increased fragility and comorbidities necessitate careful risk assessment before surgical intervention 1.
  • Comorbidities: Presence of multiple myeloma or other systemic diseases may influence treatment choices and outcomes 1.

    • Key Recommendations

  • Imaging evaluation is crucial for diagnosis and planning treatment, including assessing bone lesion characteristics and fracture risk (Evidence: Moderate 1).
  • Surgical intervention should be considered for stabilization and restoration of function in pathologic fractures, tailored to patient-specific factors (Evidence: Expert opinion 1).
  • Systemic therapy targeting the underlying neoplasm should be integrated into management to control disease progression and prevent recurrence (Evidence: Moderate 1).
