The strength of the Nex-Link construct is derived from the sum of its parts. Commercially pure titanium rods facilitate easier contouring while improving the construct’s strength. Equally impressive is the Nex-Link polyaxial screw that offers a 65º range of motion (ROM) or 6.1mm of offset to minimize the effort needed to capture the rod.
Independent lab results have demonstrated a four-fold improvement in axial grip testing and a two-fold improvement in flexion-extension resistance over baseline competitors. This provides piece of mind when transitioning over one the most biomechanically and anatomically challenging areas of the spine—the cervicothoracic junction. Nex-Link’s strength and versatility allows for transitioning to thoracolumbar fixation systems. Its CT Junction system facilitates quicker procedures and sturdy transitions for longer constructs.
n intended to promote fusion of the cervical spine and the thoracic spine, (C1-T3), the Nex-Link Spinal Fixation System is indicated for the following: DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors. Hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine. The use of polyaxial screws is limited to placement in T1-T3 in treating thoracic conditions only. The polyaxial screws are not intended to be placed in the cervical spine. After solid fusion occurs, these devices serve no functional purpose and should be removed. In most cases, removal is indicated because the implants are not intended to transfer or support forces developed during normal activities. The physician and the patient, taking into consideration the patient’s general medical condition and the potential risk to the patient of a second surgical procedure, must make any decision to remove the device.
use of posterior spinal instrumentation in children has been reported in the literature. Preferably, children should be older than 10 to receive this implant but need not have reached skeletal maturity. In special circumstances, implants may be used at younger ages.
