“…Renfrew et al 16 recommended CT-guided percutaneous transpedicular biopsy of the spine, when the location of a vertebral body lesion does not allow easy access by means of the posterolateral approach. This preference was based on the proximity of neural elements to the pedicle.…”

Study design: This prospective study evaluates the effectiveness of transpedicular biopsy carried out under local anesthesia in obtaining diagnostic tissue from vertebral body lesions. Objective: To describe the technique of percutaneous transpedicular biopsy carried out under local anesthesia under C-arm fluoroscopy and to report the author 0 s experience. Setting: Spine hospital, Ahmedabad, Gujarat, India. Methods: Seventy-one patients who underwent transpedicular biopsy from T6 to S1 vertebral body lesions were evaluated. Biopsy specimens were obtained by passing a self-designed 5-mm diameter biopsy instrument through the pedicle into the site of the disease using C-arm fluoroscopy. Specimens were sent for histological and bacteriologic analyses. Results: Biopsy was carried out for vertebral lesions of 51 men and 20 women. Sixteen of these lesions were seen in thoracic spine, 53 in lumbar and two in sacrum. The pathologic examinations revealed infections in 25, osteoporotic wedging in 21, metastasis in eight, plasmacytoma in three, multiple myeloma in four, non-Hodgkin 0 s lymphoma in one and round cell tumor in one patient. Diagnosis was established in 63 of 71 patients (88.7%). Remaining eight patients were reported as chronic nonspecific inflammation, and were followed up for more than 6 months. Conclusion: Percutaneous transpedicular vertebral biopsy under local anesthesia is an important tool in the evaluation of vertebral body lesions, especially in older population and can be performed with minimal morbidity and high diagnostic yield as an outpatient procedure.

“…It can be performed during surgery (open biopsy) or percutaneously (closed biopsy). Percutaneous biopsy of bony lesions may be performed under the guidance of a variety of imaging modalities, such as, fluoroscopy [1-4], computed tomography (CT) [5-19], ultrasonography [20-24], and magnetic resonance (MR) imaging [25-28]. Open biopsy is a major surgical procedure that is associated with morbidity and a host of complications.…”

“…Although the use of fluoroscopy [3,4], ultrasonography [21], and MR imaging [28] has been described, CT is currently the modality of choice for guiding biopsy of lesions of the spine [5,6,8,10-12,14-19]. Ultrasonography has been advocated for guiding biopsy of cervical spine lesions, and in the thoracic and lumbosacral regions its use is limited to lesions affecting the posterior elements [21].…”

Accurate diagnosis of spine lesions is important for its successful management. Imaging–guided percutaneous biopsy is gaining increasing acceptance as a means for obtaining tissue for diagnosis. Most biopsies can be rapidly performed under local anaesthesia, with little patient discomfort and improved safety. Spinal anatomy is, however, complex with many adjacent vital structures. Good knowledge of anatomy and precise needling technique is, therefore, important. Today, biopsy of spinal lesions is best performed under computed tomography (CT) fluoroscopic guidance. Indications for imaging-guided biopsy include confirming metastasis in a patient with a known primary tumour, determining the nature of a solitary bone lesion, excluding malignancy in vertebral body compression, and investigating for infection. Among the various issues to be considered are site of lesion, location of adjacent vital structures, approach, and type and size of needle. Complications are rare, particularly when a meticulous technique is applied. In summary, CT-guided percutaneous biopsy is a safe and an effective technique for the evaluation of spinal lesions and useful in planning therapy.

“…3 Of all the imaging methods, CT is currently the method of choice for guiding biopsy of lesions of the spine for many authors. [4][5][6][7] However, in our hospital, fluoroscopy-guided percutaneous biopsy has been preferred for several years because of equipment availability and ease of craniocaudal angulation. In our experience, fluoroscopic guidance is as appropriate as CT guidance for vertebral body biopsy to diagnose infectious spondylitis.…”

BACKGROUND AND PURPOSE:CT is currently the method of choice for guiding biopsy of lesions of the spine. However, in our hospital, fluoroscopy-guided percutaneous biopsy has been preferred for several years because of equipment availability and easy craniocaudal angulation. The aim of this study was to evaluate the efficacy of fluoroscopy-guided percutaneous biopsy in a clinical setting for diagnosing infectious spondylitis.
