Kaneda System

The Kaneda device is used to treat fractured thoracic or lumbar vertebrae when it is suspected that bone fragments are present in the spinal canal. Variations on the basic forms of spinal instrumentation, such as Wisconsin instrumentation, are being refined as technology improves. A physician chooses the proper type of instrumentation based on the type of disorder, the age and health of the patient, and on the physician's experience.

The Kaneda system involves the placement of two screws in each Vertebral Body that are attached to two rods; this system allows for better derotation and creates a biomechanically stronger construct. Anterior approaches are useful for thoracolumbar curves down to L5 but cannot be used alone if there is a significant thoracic kyphosis.
