Deflection of spinal needles by the bevel.
Bevelled spinal needles sizes 22 and 25 gauge were passed through tough meat to assess the influence of bevel orientation on the path of the needle. The needle bent away from the bevel surface by about 1 mm for each centimetre of needle travel through the tissue. With an introducer, the deviation was reduced by a reduction of the distance of unsupported travel. Pencil-point needles were less de...

BACKGROUND Percutaneous diagnostic and therapeutic procedures are commonly used in the treatment of spinal pain. The success of these procedures depends on the accuracy of needle placement, which is influenced by needle size and shape. OBJECTIVES The purpose of this study is to examine and quantify the deviation of commonly used spinal needles based on needle tip design and gauge, using a bal...

comparison of spinal needle deflection in a ballistic gel model
conclusions there is clinical utility in knowing the relative deflection of various needle tips. when a procedure requires a needle to be steered around obstacles, or along non-collinear targets, the predictable and large amount of deflection obtained through use of a beveled spinal needle may prove beneficial. materials and methods six needles commonly used in spinal procedures (quincke, short...
