In cervical spondylosis, herniated discs; osteophytes; arthritic facet joints; buckled, thickened, or ossified ligamentum flavum; and hypertrophy or ossification of the posterior longitudinal ligament may all cause multilevel cervical stenosis, resulting in spinal cord compression. Chronic compression of the cervical spinal cord causes the clinical syndrome of cervical spondylotic myelopathy (CSM) Laminoplasty is an effective procedure for treating cervical spondylotic myelopathy (CSM). The main goals of laminoplasty are to widen the central spinal canal and decompress the spinal cord, preserve the protective structures of the spine, and preserve spinal mobility. The TARDISTM Laminoplasty System is a comprehensive set of implants and instruments designed for a systematic approach to cervical laminoplasty procedures. The TARDISTM Laminoplasty System is intended for use in the lower cervical and upper thoracic spine (C3–T3) after a laminoplasty has been performed. The system is also designed to keep the spacer/allograft in place in order to prevent the spacer/allograft from expulsion or impinging the spinal cord.
