Percutaneous trephine bone biopsy of the thoracic spine.

The authors performed six consecutive percutaneous trephine biopsies of the thoracic spine under local anesthesia, using computed tomography to localize lesions and guide needle placement. The details of the technique are illustrated. Complications were not found. The authors conclude that closed large needle biopsy of the thoracic spine can be performed safely with the aid of computed tomography.
