Threaded Fusion Cage(TFC)를 이용한 척추 전전위증 수술환자에서의 임상 및 방사선학적 소견의 분석 = Clinical, radiological analysis of Threaded Fusion Cage(TFC) in surgical treatment of spondylolisthesis

다국어 초록 (Multilingual Abstract)

The indications for surgical treatment of spondylolisthesis are pain unrelieved by conservative treatment, persistent neurologic signs, progression of the slip or slip greater than 50 per cent and a postural deformity or walking difficulty due to tight hamstring muscles.
The goal of operation for spondylolisthesis is relieving radiculopathy and low back pain with preventing further progression of the slip through decompression of neural elements and fusion for pseudoarthrosis.
The authors performed posterior lumbar interbody fusion by using of Threaded Fusion Cage(TFC) for 23 patients of spondylolisthesis.
All patients have been followed from 3 months to 12 months.
We studied the clinical and radiological outcomes for all patients and verified the relationship between clinical outcomes and radiological findings.
Summaries of the results are as followings.
1) Successful bone fusion was achieved in 20 out of 23 cases (87%).
2) Neurological signs were improved in 20 out of 23 cases (87%)
3) The majority of cases which demonstrated radiologic bone fusion also showed clinical improvement.
Posterior lumbar interbody fusion using TFC was useful in treatment of mild degree spondylolisthesis.
