The OnControl bone marrow biopsy system (OBM) offers a feasible and safe method for CT-fluoroscopy guided bone biopsy, significantly reducing procedure time and radiation exposure compared to manual Jamshidi needles.

Area of Science:

Medical Devices
Interventional Radiology
Oncology

Background:

CT-fluoroscopy guided bone biopsy is crucial for diagnosing bone lesions.
Traditional methods using manual needles can be time-consuming and involve significant radiation exposure.

Purpose of the Study:

To assess the feasibility of a battery-powered intraosseous device for CT-fluoroscopy guided bone biopsy.
To compare the performance of the OnControl bone marrow biopsy system (OBM) against the classic Jamshidi Needle.

Main Methods:

Retrospective analysis of 12 patients undergoing bone biopsy with the OBM system under CT-fluoroscopy guidance.
Comparison of OBM system data with a historical cohort using the Jamshidi Needle.

Main Results:

Published on: December 22, 2015

Technical success achieved in 11 out of 12 cases, with adequate specimens for histopathology.
Significant reduction in biopsy time (13 ± 6 min to 6 ± 4 min) and radiation dose (169 ± 87 to 111 ± 54 mGy × cm) compared to the Jamshidi Needle.
Interventional radiologists reported confidence in OBM performance, particularly in sclerotic or osteoblastic lesions.

Conclusions:

The OBM system is a safe and effective tool for CT-fluoroscopy guided bone biopsy.
Utilizing the OBM system leads to significantly reduced intervention time and radiation exposure compared to the Jamshidi Needle approach.
