    Description of Event or Problem · 1

    THE RESULTS OF A RETROSPECTIVE STUDY OF PATIENTS WHO UNDERWENT TRANSFORAMINAL LUMBAR INTERBODY FUSION (TLIF) BETWEEN (B)(6) 2004 AND (B)(6) 2009 WERE REPORTED. THE SURGICAL PROCEDURES WERE PERFORMED BY A SINGLE SURGEON AND INCLUDED SINGLE OR TWO LEVEL FUSIONS. THE PATIENTS HAD PRESENTED WITH DEGENERATIVE SPINAL CONDITIONS (SPONDYLOLISTHESIS, DISCOGENIC BACK PAIN, AND/OR LUMBAR RADICULOPATHY) AND WERE GREATER THAN (B)(6). THE PATIENTS UNDERWENT A TLIF WITH PEDICLE SCREW INSTRUMENTATION THROUGH EITHER A MIDLINE POSTERIOR OR MINIMALLY INVASIVE APPROACH. AN INTERBODY DEVICE WAS FILLED WITH RECOMBINANT HUMAN BONE MORPHOGENETIC PROTEIN-2 (RH-BMP2) SPONGES AND LOCAL AUTOGRAFT. A STANDARD DOSE OF 5 MG OF RH-BMP-2 WAS USED. THE PATIENTS WERE DISCHARGED FROM HOSPITAL DAY THREE POST-OP. LOW IMPACT ACTIVITIES WERE PERMITTED. STRENUOUS PHYSICAL ACTIVITY AND HEAVY LIFTING WERE NOT PERMITTED UNTIL SIX WEEKS POST-OP. ONE PATIENT WAS FOUND TO HAVE OSTEOLYSIS. THE PATIENT DEMONSTRATED APPROPRIATE CAGE POSITIONING ON IMMEDIATE POST-OP CT SCAN AND SUBSEQUENT POSTERIOR MIGRATION ON FOLLOW-UP CT. THE PATIENT DID NOT DEMONSTRATE WORSENING OF OSTEOLYSIS ON SUBSEQUENT FOLLOW-UP IMAGING. REVISION SURGERY WAS NOT REQUIRED DURING THE STUDY PERIOD DUE TO THE OSTEOLYSIS OR MIGRATION.
