Metastatic malignant neoplasm to trapezoid bone

Last edited: 4/10/2026

Overview

Metastatic malignant neoplasm to the trapezoid bone is a rare occurrence. The trapezoid bone is one of the carpal bones in the hand.

Diagnosis

  • Diagnosis is typically made via imaging studies such as X-ray, CT, or MRI, which can reveal bone lesions.
  • Biopsy may be required for definitive diagnosis and to determine the primary tumor type.

    • Management

  • Treatment depends on the primary malignancy and the extent of metastasis.
  • Options may include surgical resection, radiation therapy, or palliative care.
  • Internal fixation was used in a case report for a palmar dislocation of the trapezoid associated with radial subluxation of the trapezium 1.

    • Key Recommendations

  • Treatment for metastatic malignant neoplasm to the trapezoid bone should be individualized based on the primary cancer and disease burden. (Evidence: Expert opinion)
  • Surgical intervention, such as internal fixation, may be considered for specific traumatic injuries to the trapezoid bone, though not directly for metastatic disease in the provided abstract. (Evidence: Weak)
