title: Computed tomography-guided percutaneous transpedicular biopsy of the thoracic spine.
abstract: BACKGROUND
  Despite the recent, widespread use around the world of computed tomography (CT)-guided spinal biopsy for presurgical evaluation, its use has remained uncommon in Taiwan. Using 9 patients, we attempted to evaluate the safety of its use for the thoracic spine biopsy.
  
  
  METHODS
  In the past 3 years (May 1996 to May 1999), 9 patients with known thoracic or multiple spinal lesions underwent CT-guided biopsy. The patients comprised 4 men and 5 women; with ages ranging between 28 and 85 years. For the transpedicular approach, patients were laid prone on the CT table. A trephine bone biopsy needle set was used after local anaesthesia. The specimens obtained had tissue pathology and/or bacterial/tuberculosis (TB) culture.
  
  
  RESULTS
  Excellent results were achieved in 8 of the 9 patients, with no significant procedure-related complications. Among them, 2 were diagnosed as metastatic carcinomas; 3 as osteoporotic compression fractures; 2 were proved to be bacterial or tuberculosis spondylitis and the last one was a healing fracture.
  
  
  CONCLUSIONS
  CT-guided transpedicular trephine biopsy of the thoracic spine is a safe and effective method for preoperative evaluation of various thoracic spinal disorders. Based on the biopsy results, more effective treatment regimens were prescribed and, in turn, better outcomes were expected.
