Minnesota Patent of the Month – August 2021

Interbody Fusion Systems are prosthetics used in spinal fusion procedures to maintain foraminal height and decompression. These systems can often help ease access to anatomy during procedures while minimizing trauma to the patient. Spineology, Inc. has developed an enhanced Interbody Fusion System that can further reduce the necessary exposure area and improve the fluoroscopic visualization of the spinal disc site.

Unlike other lateral retractors on the market, this design does not need any actuation to perform a discectomy or to implant the interbody spacer. It’s designed with an oval shape, allowing the doctor to gain additional access that is not available in traditional, circular designs. 

In a transpsoas lateral fusion surgery, the disc site is accessed by transecting the psoas muscle. The lateral lumbar plexus runs directly through the psoas muscle. However, retracting the psoas muscle – as done in previous surgery techniques – results in immediate post-op issues from numbness to dysesthesia in the thigh. Using Spineology’s lateral retractor design, the psoas retraction is reduced by 50%, these post-op issues are seriously reduced.
