PURPOSE: To evaluate the clinical outcomes of cantilever transforaminal lumbar interbody fusion (c-TLIF) for upper lumbar diseases. MATERIALS AND METHODS: Seventeen patients (11 males, 6 females; mean +/- SD age: 62 +/- 14 years) who underwent c-TLIF using kidney type spacers between 2002 and 2008 were retrospectively evaluated, at a mean follow-up of 44.1 +/- 12.3 months (2 year minimum). The primary diseases studied were disc herniation, ossification of posterior longitudinal ligament (OPLL), degenerative scoliosis, lumbar spinal canal stenosis, spondylolisthesis, and degeneration of adjacent disc after operation. Fusion areas were L1-L2 (5 patients), L2-L3 (9 patients), L1-L3 (1 patient), and L2-L4 (2 patients). Operation time, blood loss, complications, Japanese Orthopaedic Association (JOA) score for back pain, bone union, sagittal alignment change of fusion level, and degeneration of adjacent disc were evaluated. RESULTS: JOA score improved significantly after surgery, from 12 +/- 2 to 23 +/- 3 points (p < 0.01). We also observed significant improvement in sagittal alignment of the fusion levels, from - 1.0 +/- 7.4 to 5.2 +/- 6.1 degrees (p < 0.01). Bony fusion was obtained in all cases. One patient experienced a subcutaneous infection, which was cured by irrigation. At the final follow-up, three patients showed degenerative changes in adjacent discs, and one showed corrective loss of fusion level. CONCLUSION: c-TLIF is a safe procedure, providing satisfactory results for patients with upper lumbar degenerative diseases Keywords : Adult,adverse effects,Aged,Back Pain,blood,Blood Loss,Surgical,complications,Female,Follow-Up Studies,Humans,Intervertebral Disc Displacement,Kidney,Lumbar Vertebrae,Male,methods,Middle Aged,Pain,Scoliosis,Spinal Canal,Spinal Diseases,Spinal Fusion,Spinal Stenosis,Spondylolisthesis,surgery,Time Factors,Treatment Outcome,, Transforaminal,Lumbar,Interbody,Fusion, dr Mo Akmal
