Lumbar Foraminal Rasps

Surgical instruments which aid in the decompression of the lumbar neuroforamen (NF), where the nerves exit the spine.


The design has the following salient features:

  • Made in the USA of stainless steel, these instruments have two parts, a body and a rasp.
  • The angle of the rasp from the body is at an angle allowing a seamless decompression of the NF.
  • Both the distal tip and the base of the rasp are curved gently to avoid piercing the exiting nerve root.
  • The angle of the rasp teeth allows for decompression of the ligaments and bone spurs towards the spinal canal where they can be cleared away.
  • The rasp has a thin profile to allow working in a tight NF without compressing the exiting nerve root.

Instructions for Use

  • The surgeon passes the instrument into the neuroforamen over the exiting nerve, all the while visualizing the relationship of the instrument to the nerve root. While applying a gentle upward force, the instrument is removed from the neuroforamen resecting the compressive ligament and bone spurs. This process is repeated as many times as the surgeon deems necessary to decompress the neuroforamen appropriately.

Sterilization Guideline

For gravity-displacement steam autoclave sterilization: 121 Centigrade (250 F) for 30 minutes with a 30 minutes drying time or follow the institution’s protocol for stainless steel instruments.
