Closed intramedullary biopsy for metastatic disease

Area of Science:

• Orthopedic Surgery
• Surgical Oncology
• Oncologic Imaging

Background:

• Metastatic fractures of long bones often require surgical stabilization with intramedullary nails.
• A histological diagnosis is crucial for planning adjuvant therapy in patients with primary or secondary bone tumors.
• Current biopsy methods, like open biopsy or percutaneous puncture, can be invasive or less reliable.

Purpose of the Study:

• To present a simple, reliable technique for closed biopsy of intramedullary reamings during fracture fixation.
• To enable histological diagnosis of malignancy presenting as a fracture.
• To facilitate timely adjuvant therapy planning for bone cancer patients.

Main Methods:

• A closed biopsy technique utilizing intramedullary reamings obtained during fracture fixation surgery.
• The technique is applicable to both femur and humerus fractures.
• Specimens are collected using intramedullary reamers during the intramedullary nailing procedure.

Main Results:

• The technique provides a reliable method for obtaining intramedullary specimens for histological diagnosis.
• It is suitable for lesions in both the femur and humerus.
• This closed biopsy approach simplifies the diagnostic process at the time of fracture stabilization.

Conclusions:

• Closed biopsy from intramedullary reamings is a practical and effective method for diagnosing bone malignancies.
• This technique can be integrated into the standard procedure for intramedullary fixation of metastatic fractures.
• It offers a reliable alternative for obtaining diagnostic tissue, improving patient management.
