About spinal instrumentation and implants

Most spine surgeries will involve some sort of instrumentation, hardware or fixation device. This is a normal part of treatment for a herniated disc.

A disc in the spine resembles a jelly donut. When a disc herniates, or ruptures, the jelly center breaks through the wall of the disc and can press on nearby nerve roots. This pressure can cause radiating pain, numbness or weakness in the leg or foot (herniated disc in the low back) or radiating pain, numbness or weakness into the arm or hand (herniated disc in the neck). While watchful waiting can be used for a sort time for radiating pain, the symptom of numbness or weakness in a leg or arm represents an serious symptom that if left untreated, the numbness or weakness could become permanent and lifelong. Loss of control of the bowel or bladder from a herniated disc is called “cauda equina” and the person needs to go to an emergency room within 24 hours for treatment to prevent permanent loss of bowel or bladder control.

A herniated disc isn’t actually repaired. Instead, depending upon the severity of the herniation, the surgeon may remove the part of the disc nucleus that has broken through the wall of the disc and is pressing on a nerve. This is called a “discectomy.”

The issue with a simple discectomy is that the wall of the herniated disc cannot be repaired, and more nucleus can come out in the future causing worse symptoms and requiring a second spine surgery.

Consequently, in many spine surgery cases the entire herniated disc is removed and a piece of bone is placed in the space previously occupied by the disc. This typically relieves the herniated disc symptoms at that level permanently. This is called a spinal fusion.

To hold the piece of bone in place, the surgeon also typically uses metal instrumentation including a metal plate and screws that hold everything in place.

About AXIS360 Surgical instrumentation

The spine surgeon using Kahtnu Surgical instrumentation has compared this hardware to other available options and has determined that Kahtnu Surgical is the best option for the particular patient. Currently, related to spine surgery, Kahtnu Surgical produces instrumentation for the following spine surgeries:
Anterior Cervical Discectomy & Fusion (ACDF)

This is a spine surgery to relieve the symptoms of a herniated disc in the neck. During neck surgery, the spine surgeon makes a small incision in the front of the neck (anterior approach) to access and remove the herniated disc. Once the disc is removed, a piece of bone is inserted into the vacated disc space and a plate and screws are used to secure the fusion.

Pedicle Screw Fixation

This spine surgery makes use of special medical grade screws to secure metal plates to the pedicles. Pedicle screws are typically placed into the vertebrae above and below the fusion site. A rod or plate is used to connect the screws which prevents movement and allows the bone graft to heal.

Posterior Lumbar Interbody Fusion (PLIF)

This spine surgery is performed to treat a herniated disc; stenosis; spinal instability; or to correct scoliosis or a spinal curve. Posterior means the surgery is done through the back with the patient lying on their stomach during surgery.

Kahtnu Surgical Clinical Research, Medical Education & Philanthropy

A portion of Kahtnu Surgical’s revenues are dedicated to the Kenai Outreach Foundation, an independent 501c3 not-for-profit entity that embraces a three-pronged strategy for meeting surgeons’ practice and professional needs: Clinical Research, Medical Education and Philanthropy. This contribution acts as an investment in research and education to produce ongoing advances in spine surgery technology.
