다국어 초록 (Multilingual Abstract)

Purpose : To evalute the clinical and radiological result treated by transforaminal lumbar interbody fusion(TLIF) and transpedicular instrumentarion for lumbar disease.
Materials and Methods : Twenty-seven cases with follow-up over 12 months were analyzed retrospectively. Etiologic conditions were lumbar stenosis in 15 cases, failed back surgery syndrom in 7 cases, spondylolithesis in 3 cases, lumbar disc with instability in 2 cases. Data regarding blood loss, operative time were recorded. Clinical result was analyzed by Kim's criteria. Radiologic evaluation containing the bone union and intervertebral space height was assessed by simple X-ray.
Result : The satisfactory clinical result rate was 86%. Postoperative fusion states were bone union in situ 28 level, delayed union in 3 level, Disc height was changed from 10.6mm preoperatively to 13.1mm postoperatively and remained 12.2mm at the latest follow-up. The average blood loss was 480ml. The average operation time was 185 min. Postoperative complications were dural laceration and wound infection. There were no nonunion, instrument breakage and nerve palsy.
Conclusion : Transforaminal lumbar interbody fusion(TLIF) and transpedicular instrumentarion for lumbar disease showed excellent clinical and radiological result. TLIF also provide elimination of the need for prolonged retraction of the dura and conus medullaris and maintenance of the normal muscular attachments, but long-term clinical outcomes studies are necessary to address issues concerning the clinical effectiveness of these procedures.
