ObjectiveTo investigate the feasibility and efficacy of sight-guided percutaneous unilateral translaminar facet screw fixation (TLFSF) with interbody fusion for treatment of lower lumbar vertebra diseases.MethodsTwenty-nine adult patients with lower lumbar disease underwent sight-guided percutaneous unilateral TLFSF combined with microsurgical spinal decompression, discectomy, and interbody fusion from June 2007 to June 2008. All 29 patients had low back pain caused by lumbar disc degeneration (20 cases), in situ recurrent lumbar disc herniation (2), primary diskitis (1), lumbar disc herniation with spinal stenosis (3), and first-degree lumbar degenerative spondylolisthesis (3). Twenty-three cases had lesions at L4,5 ; three at L5 S1 , one at L3,4 , L4,5 , and two at L4,5 , L5 S1 .ResultsNo patient experienced significant postoperative complications. The mean incision length was 4.48 ± 0.55 cm; operative time 1.34 ± 0.22 h; intraoperative blood loss 280 ± 175 mL; and postoperative drainage volume 165 ± 85 mL. Screw position results: type I, 21 cases (23 segments); type II, 7 cases (8 segments); and type III, 1 case (1 segment). Twenty-eight patients were followed up for 24-60 months (average, 47.5 months). Interbody fusion rate was 93.5%). Postoperative intervertebral height recovered significantly; however, loss of intervertebral height occurred during follow-up.ConclusionSight-guided percutaneous unilateral TLFSF with interbody fusion for treatment of lower lumbar disease is simple and minimally invasive, with good screw accuracy and security, high fusion rate, and good efficacy. However, specific surgical indications must be strictly followed.© 2014 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.
