Specific sections for implants and instrumentation highlight important user information for only those devices. GENERAL INFORMATION Implants Spinal Elements’ Mercury Spinal System is comprised of a variety of screws, hooks, rods, and connectors that are used for attachment to the non-cervical spine (T1-S1). System components are available in a multitude of sizes and configurations. A variety of constructs may be assembled to suit the individual pathology and anatomy of the patient. All implant components are made from titanium alloy (Ti-6Al-4V) conforming to ASTM F 136 or ASTM F 1472. Cobalt-Chrome Rods are made from cobalt chromium alloy (CoCr) conforming to ASTM F 1537. Spinal Elements’ instruments are manufactured from various stainless steels, aluminums, and polymers. All materials used have a history of use in such instruments. All implants are intended for single patient use only and should not be reused (used in additional patients) under any circumstances. Reuse may result in serious injury or death. Components from this system should not be used in conjunction with components from other systems. Navigated instruments are manual surgical instruments manufactured from stainless steel, as specified in ASTM F899 or ASTM A564. Navigated instruments are non-sterile and are intended to be used with the Medtronic StealthStation® System. INDICATIONS The Mercury® Spinal System is intended to provide immobilization and stabilization of the spine in skeletally mature patients as an adjunct to fusion for procedures of the thoracic, lumbar, and sacral spine (T1-S1). Screws may be placed from the thoracic spine through the sacral spine and into the ilium. This system is intended for anterior/anterolateral non-pedicle fixation, posterior non-pedicle fixation, and posterior pedicle fixation for the following indications: degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e., fracture or dislocation), spinal stenosis, curvatures (i.e., scoliosis, kyphosis, and/or lordosis), tumor, pseudoarthrosis, and failed previous fusion. This system is intended to be used with bone graft. The Spinal Elements Mercury Fixation System may be used in conjunction with the Spinal Elements Overwatch System. In order to achieve additional levels of fixation, the Mercury or Overwatch Fixation Systems may be connected to the Lotus Posterior Cervical/Thoracic rod connectors. Transition rods with differing diameters may also be used to connect the Lotus Posterior Cervical/Thoracic Spinal System to the Mercury or Overwatch Spinal Systems. Refer to the Lotus Posterior Cervical/Thoracic Spinal System package insert for a list of Lotus indications for use. When used for posterior non-cervical pedicle screw fixation in pediatric patients the Mercury and Overwatch implants are indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. These devices are to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach. Spinal Elements Navigated Instruments are intended to be used during the preparation and placement of Spinal Elements Mercury® screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. These instruments are designed for use with the Medtronic StealthStation® System, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy. CONTRAINDICATIONS 1. Patients with known or probable intolerance to the materials used in the manufacture of this device. 2. Patients with infection, inflammation, fever, tumors, elevated white blood count, obesity, pregnancy, mental illness and other medical conditions which would prohibit beneficial surgical outcome. 3. Patients resistant to following post-operative restrictions on movement especially in athletic and occupational activities. 4. Use with components from other systems.
