Spinal fusion surgery is a procedure to correct problems with individual vertebrae, the interlocking bones making up the spine, by preventing movement of the affected bones. Although some early generation expandable implants have been introduced, the most commonly used device for posterior lumbar interbody fusions is a fixed size PEEK or titanium cage inserted between the vertebral bodies by “hammering in” the device to make the patient’s spine conform to the manufacturer’s implant.

To avoid causing invasive damage by “hammering in” too large a device, a surgeon may have to choose a smaller implant, thereby risking inadequate disc height restoration and nerve root decompression, and increasing the possibility that the implant will be expelled.

There is a growing desire among surgeons to reduce the risk of harm to the patient with minimally invasive techniques. Spinal Jaxx implants meet that need and take a leap forward in personalized medicine in the spine. Spinal Jaxx devices conform to the particular anatomical needs of each individual patient. Our design allows the surgeon to insert the device between the vertebral bodies through a small opening and expand in situ to a larger size as needed, providing a snug fit.

Spinal Jaxx allows for an infinite number of height selections within the minimum and maximum heights of a particular implant. No hammering or adjusting the patient’s anatomy is required.
