Abstract

The authors reviewed the results of 77 consecutive patients who underwent transforaminal lumbar interbody fusion (TLIF) from January 2005 to July 2007 at a single institute. The preoperative diagnoses included degenerative or isthmic spondylolisthesis with instability. The average age of the patients in this study was 64.3 years, and there were 33 men and 44 women. All patients were followed clinically for a minimum of 12 months after surgery at a mean of 24.2 months. Clinical outcomes were assessed by the JOA (Japanese Orthopaedic Association) score, the VAS (visual analog scale), and the ODI (Oswestry disability index). Radiological findings and fusion rate were also investigated. Clinical recovery of all patients regarding outcome measures was significant at any time of the follow-up (p>0.01). Minor surgical complications and reoperation occurred in 9.1% and 5.2% of patients respectivelly. There was a 2.6% incidence of postoperative transient radiculopathy without major complications including permanent neurologic deficit. Fusion success was observed in 97.5% of surgical sites. TLIF is a safe and effective method of achieving lumbar fusion resulting in a high fusion success rate and a significant clinical recovery of the patients without serious and permanent surgical complications.
