Thin spinal or biopsy needle guidance.
The thin needles that are used for myelography or biopsy are easily deflected in the body. We describe a simple method used to guide the tip of these needles to the target area using needle-hub rotation. This procedure was successfully used in more than 260 direct C1-C2 punctures for cervical myelography.
