What is it indicated for?
The Atoll Cervico-Thoracic System is indicated to promote fusion of the cervico-thoracic regions of the spine (Cl - T3). The intended indications are as follows: · Degenerative Disc Disease (as identified by neck or back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) · Spondylolisthesis · Spinal Stenosis · Fracture/Dislocation * Tumors • Pseudoarthrosis * Revision of previous cervical and upper…
Read the full statement (151 words)
The Atoll Cervico-Thoracic System is indicated to promote fusion of the cervico-thoracic regions of the spine (Cl - T3). The intended indications are as follows:
· Degenerative Disc Disease (as identified by neck or back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies)
· Spondylolisthesis
· Spinal Stenosis
· Fracture/Dislocation
* Tumors
• Pseudoarthrosis
* Revision of previous cervical and upper thoracic spine surgery
The use of the screws is limited to placement in the upper thoracic spine (T1-T3) in treating thoracic conditions only. The screws are not intended for use in the cervical spine.
The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (Cl -T3) spine.
The Atoll Cervico-Thoracic System can also be linked to the Theken Coral Spinal System with the use of transitional rods and rod connectors.
Indications for use as stated in the FDA summary.
