Intended Use

When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput -T3), the MOUNTAINEER OCT Spinal System is intended for:

  • Degenerative Disc Disease (DDD),
  • spondylolisthesis,
  • spinal stenosis,
  • fracture/dislocation,
  • atlanto/axial fracture with instability,
  • occipitocervical dislocation,
  • revision of previous cervical spine surgery,
  • and tumors.

The occipital bone screws are limited to occipital fixation only. The use of the minipolyaxial screws is limited to placement in the cervical and upper thoracic spine (C1-T3). The Songer Cable System, to be used with the MOUNTAINEER OCT Spinal System, allows for wire/cable attachment to the posterior cervical spine. The MOUNTAINEER OCT Spinal System can also be linked to the ISOLA™, TiMX™, MONARCH®, MOSS MIAMI™, and EXPEDIUM Systems using the dual wedding band and axial connectors, and via dual diameter rods.

The surgeon must be thoroughly knowledgeable not only in the medical and surgical aspects of the implant, but must also be aware of the mechanical and metallurgical limitations of metallic surgical implants.

Postoperative care is extremely important. The patient must be instructed in the limitations of the metallic implant and be warned regarding weight bearing and body stresses on the appliance prior to firm bone healing. The patient should be warned that noncompliance with postoperative instructions could lead to failure of the implant and possible need thereafter for additional surgery to remove the device.
