Medtronic, a US-based medical device company, has introduced its fifth-generation spinal fusion system, called CD Horizon Solera Spinal System Sagittal Adjusting Screw (SAS), which could be used in the surgical correction of complex spinal problems.

Comprising a fixed head which is made up of cobalt chrome that contains a sliding saddle, this new concept offers vertebral body controls which can accommodate the seating of rods, thereby allowing surgeons to place the adjusting screws in the natural kyphotic (outward) and lordotic (inward) curves of the spine.

As the system can accommodate several rod material options, it presents doctors a a range of choice to treat various kinds of spinal conditions, the company claimed.

CD Horizon Solera Spinal System Sagittal Adjusting Screw can be used in the treatment of several conditions such as degenerative disc disease, spinal stenosis, fracture, dislocation, failed previous fusions, tumors and, adolescent idiopathic scoliosis.

Medtronic senior vice president Doug King said that the Sagittal Adjusting Screw is another key element in enhancing the capability of its CD Horizon Solera pedicle fixation system.

"It brings new innovation to the market and extends our industry-leading portfolio of spinal therapies," King added.

The company has cautioned that there are several risks associated with this kind of system such as disassembly, loosening, breakage or bending of components, microfracture, fracture, damage, resorption, or penetration of any spinal bone.

Therefore, it is vital to select the appropriate size, shape, and design of the implant, though each surgical case may not always yield successful results.

The company has also warned that the device should be used only when definitive fusion is being performed at all instrumented levels.
