Read the full statement (152 words)
The NEXXT MATRIXX® corpectomy devices are indicated for use in the cervical spine (C2-T1) and thoracolumbar spine (T1-L5) in skeletally mature patients to replace a diseased, collapsed, damaged, or unstable vertebral body due to tumor, osteomyelitis, trauma (i.e. fracture), or for reconstruction following corpectomy performed to achieve decompression of the spinal cord and neural tissues in degenerative disorders. The NEXXT MATRIXX® corpectomy devices are also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical, thoracic, and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon’s discretion. The NEXXT MATRIXX® corpectomy devices are intended for use with autograft or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft, as an adjunct to fusion and with FDA-cleared supplemental internal fixation.
Indications for use as stated in the FDA summary.
