Indications
Cadence is a vertebral body replacement device that is intended for use in the thoracic and/or thoracolumbar spine (T3 - L5) to replace a collapsed, damaged or unstable vertebral body resected or excised (i.e., partial or total vertebrectomy procedures) due to tumor or trauma (i.e., fracture).
Cadence is designed to restore the biomechanical integrity of the
anterior, middle and posterior spinal column even in the absence of fusion
for a prolonged period. Cadence is intended to be used with bone
graft.

Contraindications
-
Disease conditions which have been shown to be safely and predictably
managed without the use of internal fixation devices are relative
contraindications to the use of these devices.
-
Active systemic infection or infection localized to the site of the
proposed implantation are contraindications to implantation.
-
Severe osteoporosis is a relative contraindication because it may prevent
adequate fixation of spinal anchors and thus preclude the use of this or
any other posterior spinal instrumentation system.
-
Any entity or condition that totally precludes the possibility of fusion,
i.e. cancer, kidney dialysis or osteopenia, is a relative
contraindication. Other relative contraindications include obesity,
pregnancy, certain degenerative disease, and foreign body sensitivity. In
addition, the patient's occupation or activity level or mental capacity
may be relative contraindications to this surgery. Specifically, some
patients may, because of their occupation or lifestyle, or because of
conditions such as mental illness, alcoholism or
drug abuse, place undue stresses on the implant.
-
Known patient sensitivity to device materials (titanium alloy, Ti-6Al- 4V).
- When used without posterior fixation, the device should only be used for Grade 1 or less spondylolisthesis or retrolisthesis.
