Needle biopsy of bone: a simplified technique

Area of Science:

• Orthopedic Surgery
• Histopathology
• Diagnostic Techniques

Background:

• Histopathological examination of bone requires adequate tissue samples.
• Accessing deep-seated bones, such as vertebral bodies, for biopsy can be challenging.
• Current biopsy methods may not always yield sufficient bone material for accurate diagnosis.

Observation:

• A slight modification to a commonly available needle was developed.
• This modified needle was used to obtain bone samples from deep-seated locations.
• The procedure was applied to vertebral bodies and other deep bones.

Findings:

• Adequate amounts of bone for histopathology were successfully obtained using the modified needle.
• The technique was employed in 51 consecutive cases.
• Forty-one correct diagnoses were made, demonstrating high diagnostic accuracy.

Implications:

• This modified needle technique offers a minimally invasive approach for bone biopsy.
• It improves the ability to diagnose conditions affecting deep-seated bones.
• The method has the potential to enhance diagnostic yield in orthopedic and oncologic pathology.
