Brief Summary

Spinal biopsy is important to obtain culture and histopathological diagnosis in spine infection and tumors. To date, there is no prospective randomized study comparing both techniques. Therefore, the aim of this prospective randomized trial was to evaluate the accuracy, safety and diagnostic outcome of both these techniques.A prospective randomized trial was performed in 60 patients divided equally into fluoroscopic and CT guided spinal biopsy groups. Transpedicular approach was done with 8G core biopsy needle. Specimens were sent for histopathological examinations and cultures. Diagnosis were made based on biopsy results, clinical criteria and disease progression during 6 months follow up. Radiation expose to patients and doctors were measured with optically stimulated luminescence dosimeters (OSLDs).

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of fluoroscopic and CT guided spinal biopsy

    Diagnostic accuracy were determined based on true positive, true negative, false positive and false negative biopsy findings

    6 months

Secondary Outcomes (3)

  • Radiation expose to patients and doctors

    During biopsy

  • Pre biopsy and post biopsy pain score assessed by visual analogue scale (VAS)

    48 hours post biopsy

  • Complications of spinal biopsy

    During and 48 hours after spinal biopsy

Study Arms (2)

Fluoroscopy Guided Spinal Biopsy Arm

ACTIVE COMPARATOR

Fluoroscopy guided spinal biopsies were done by spine surgeons in the operation theatre using C-Arm fluoroscopy device (OECFluorostar7900Compact - GE®). C-arm image intensifier was positioned until fluoroscopic beam was collinear with the corresponding vertebral body on AP view prior to insertion of biopsy needle

Diagnostic Test: Fluoroscopy Guided Spinal Biopsy

CT guided Spinal Biopsy Arm

ACTIVE COMPARATOR

CT guided spinal biopsies were done by radiologist under guidance of 128-slice CT scanner (SOMATOM Definition AS+, Siemens Medical Solutions USA, Inc.). Preliminary axial CT scanning was done in bone window (window width, WW:2500; window level, WL:500) at the pre-selected levels decided from previous imaging to plan the needle access. Biopsy was then performed under sequential CT-fluoroscopy scan.

Diagnostic Test: CT guided Spinal Biopsy

Interventions

Spinal biopsy done via Transpedicular approach with an 8-gauge T-Lok™ bone marrow biopsy needle under fluoroscopic guidance. Samples collected were sent to laboratories for histopathological examination (HPE), culture and sensitivity (bacteriology, mycology and acid-fast bacilli), staining (Gram and Ziehl-Neelsen) and polymerase chain reaction (PCR) test for Mycobacterium tuberculosis.
