Radiculopathy is a common diagnosis among patients with pain that radiates from the neck through the shoulders and arms and it is often caused by a compressed nerve root. In some cases, anterior cervical procedures may not completely address the problem and posterior intervention is required.
The CerLoc Posterior Cervical Fusion system uses a minimally invasive surgical technique to provide indirect decompression and stabilize the cervical spine. The simple instrumentation is used to access, decorticate the facet joints, and place the implants.
- Increase foraminal volume – Interfacet allograft increases foraminal height, width, and area which may be compressing the exiting nerve root1
- Posterolateral fusion – Allograft can be used in conjunction with posterior instrumentation to aid in posterolateral fusion
- Stabilization of the segment – Stabilization of the facet joints increases the stiffness of the segment, providing an optimal environment for fusion2
- Biomechanics – Patented implant geometry limits motion due to the rectangular body limiting flexion/extension and the dual vertical stabilizers limiting both axial rotation and lateral bending
- Lordosis Correction – Unique implant geometry helps restore lordosis in addition to increasing the foraminal volume
- Anti-Migration – Tapered design, vertical stabilizers, and press-fit sizing mitigate the possibility of implant migration
- Decortication – Decortication is efficiently performed as part of the procedure
