Intended Use

When intended to promote fusion of the cervical spine and the thoracic spine, (C1-T3), the NexLink 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 trauma in the cervical/upper thoracic (C1-T3) spine. The use of multiaxial screws is limited to placement in T1-T3 in treating thoracic conditions only. The use of multiaxial screws are not intended to be placed in the cervical spine.

Device Story

Nex-Link Spinal Fixation System is a posterior spinal implant system consisting of longitudinal members, hooks, rods, and multiaxial screws. Designed for fixation and stabilization of the cervical and upper thoracic spine (C1-T3) to promote fusion. Subject device is a Variable Crosslink modification to the predicate system. Used by surgeons in clinical settings to stabilize the spine following trauma or degenerative conditions. Provides mechanical support to the spinal column; facilitates fusion. Operates via standard orthopedic fixation principles; no electronic or software components.

Clinical Evidence

No clinical data was required or provided for this submission. Substantial equivalence was established through non-clinical laboratory and bench testing.

Technological Characteristics

Posterior spinal fixation system consisting of longitudinal members, hooks, rods, and multiaxial screws. Mechanical fixation device. No energy source, software, or connectivity. Sterilization method not specified.

Indications for Use

Indicated for patients requiring cervical and thoracic (C1-T3) spinal fusion due to DDD (discogenic neck pain with confirmed degeneration), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion, or tumors. Hooks and rods indicated for stabilization following trauma. Multiaxial screws restricted to T1-T3 thoracic use; contraindicated for cervical spine placement.

Regulatory Classification

Identification

A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.
