“Karma is not just another iteration of a procedure or device. This is innovation in the true sense of the word — it is disruptive and improves the lives of our patients.”

Conventional Fixation

Traditional fixation achieves clinical goals but often with unintended consequences.

  • Rigid fixation can lead to:
    • Stiffness of the instrumented segments1
    • Stress concentration of implants1
    • Stress shielding of interbody space
    • Adjacent segment disease and hardware related discomfort may occur2
  • Fixation and stability in patients with poor bone quality can be challenging
  • Screws loosening rates are >60% in osteoporotic bone3
  • Mal-positioning of screws can lead to neurological damage and reoperations

“Those with severe leg pain (neurogenic claudication or radiculopathy) and degenerative spondylolisthesis are ideal for this device. It’s fantastic that…”

“…you can do this surgery on an outpatient basis, meaning less blood loss, a smaller incision, and patients can leave the same day. In our efforts to ‘do no harm,’ we should consider not putting an older person through a larger-than-necessary surgery.”

Revolutionary Fixation

Karma achieves the clinical goals of traditional fixation without the unintended consequences.

  • Circumferential PEEK band immobilizes and compresses the facet joint to facilitate fusion
  • Utilizes cortico-pedicular corridor for posterior fixation​
  • Patient centric: metal-free, low radiographic artifact, low-profile construct
  • Ideal for outpatient surgery and the ASC

“The Karma fixation system represents a significant advancement in the treatment of degenerative spondylolisthesis”

“…offering a less invasive, yet highly effective alternative to traditional fixation methods.
Its innovative approach not only reduces surgical time but also minimizes the risk associated with extensive tissue disruption, making it a preferable option for patients.”
