Interspinous Spacer

Minor intervention - major effect

Alleviation and pain relief from a gentle, minimally invasive procedure

IMPALA is inserted dorsally between two spinous processes using a minimally invasive technique. Permanent expansion of the intervertebral foramen reduces compression on the nerves. The patient is instantly relieved of pain as a result.

IMPALA comprises three components:

  • Two wings that can be spread to fix the implant in place
  • A locking plate to ensure that the implant remains expanded even under stress.

A simple set consisting of a few instruments suffices to ensure that the procedure is safe and straightforward. IMPALA does not require any other fixation elements such as screws or straps, and leaves the bony structures intact. 

IMPALA is used for the purposes of decompression between the spinous processes of L1-S1 of the lumbar spine in the following situations:

  • Radiologically confirmed, moderate stenosis of the spinal canal of varying etiology with neurological impairment, resulting in claudication and/or radicular symptoms
  • Moderate impairment in which, according to experience, symptoms are alleviated by flexion, such as radicular symptoms with or without concomitant back pain
  • Implant surgery should only be performed if non-surgical methods have not led to any improvement and the attending surgeon has confirmed the indication
  • The procedure is limited to one or two levels

Product-specific advantages

  • Minimally invasive procedure
    • Little stress or risk to the patient
  • Minor damage to natural structures
    • Supraspinal ligament and bony structures are not preserved
  • Short operating time
    • Particularly gentle for older patients and those with multiple morbidities
  • Safe procedure
    • The approach and implant are positioned at a good distance away from sensitive structures
  • Tantalum markers
    • Excellent visibility for radiological verification of the position
