LOW PROFILE CERVICAL CURETTE

Low profile cervical curette is a surgical instrument designed for patients that present with cervical spinal stenosis from herniated disc, ligament overgrowth or osteophytes causing spinal cord compression. The low profile cervical curette provides a simpler and more effective decompression of the posterior aspect of the cervical vertebral body (VB) when performing total disc replacement (TDR) and anterior cervical discectomy and fusion (ACDF). It may also be used less frequently in cases of posterior cervical foraminotomies.

Why you MUST use our Low Profile Cervical Curette?

A major advantage of LPCC is its ability to decompress the spinal canal behind the vertebral body caused by a disc herniation/extrusion or hypertrophied ligament by way of an anterior cervical discectomy and fusion (ACDF).  This advantage eliminates the need for a cervical corpectomy (vertebrectomy) to access the spinal canal resulting in the following benefits:

  1. Shortening of the operating time
  2. Higher fusion rate via ACDF
  3. Less likelihood of the epidural hematoma formation and the resultant cord compression
  4. Avoidance of the additional posterior cervical stabilization seen in many of the corpectomy cases hence lowering the overall cost by reduction of the OR time and the additional hardware used
  5. Avoidance of the post-operative cervical collar often used after cervical corpectomies but not ACDFs

DESIGN

  • The low profile tip allows it to be passed anterior to the thecal sac without concerns of spinal cord compression compared to commonly used up-angle curettes.

  • The angle of the tip is optimized to allow passing the curette behind the vertebral body without levering the instrument on the thecal sac.

  • The optimized length of the tip allows surgeons to reach areas previously inaccessible unless a partial corpectomy was performed up to as much as ¼ height of the VB.

  • The cutting surface is designed to effectively decompress any sequestered disc, hypertrophied posterior longitudinal ligament (PLL) or osteophytes behind the VB. 

SIMPLE TO USE

The surgeon passes the instrument underneath or over the PLL to decompress the central canal behind the superior and inferior posterior endplates. The procedure is repeated as many times as the surgeon deems appropriate.

LUMBAR FORAMINAL RASPS

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

DESIGN

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.

SIMPLE TO 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.
