Spine surgery showdown: new titanium cage may fuse bones faster

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Subject is scheduled to undergo combined interbody and posterolateral spinal fusion surgery using either the Medtronic Adaptix™ titanium cage or Medtronic CAPSTONE® PEEK cage in conjunction with a 50:50 mixture of local autograft and GRAFTON™ DBM DBF, and supplementation with a pedicle screw system. 2. Subject must be over the age of 18 years old. 3. Subject has been unresponsive to conservative care for a minimum of 6 months. 4. The subject must in the investigator's opinion, be psychosocially, mentally, and physically able to fully comply with this protocol including the required follow-up visits, the filling out of required forms, and have the ability to understand and give written informed consent. Exclusion Criteria: 1. Subjects with previous lumbar arthrodesis surgery. 2. Subjects requiring additional bone grafting materials other than local autograft bone or GRAFTON™ DBM DBF. 3. Subject has inadequate tissue coverage over the operative site. 4. Subject has an open wound local to the operative area, or rapid joint disease, bone absorption, or osteoporosis. 5.
