Transforaminal lumbar interbody fusion (TLIF) is a relatively new technique of lumbar arthrodesis
via posterior transforaminal approach to the disc, indicated mainly in cases of degenerative disc
disease, low grade spondylolisthesis and reoperation for disc herniation, especially when there is
indication for interbody fusion and posterior decompression. The aim of the study is to asses and
evaluates the outcome of posterior instrumeneted transforaminal lumbar interbody fusion as a surgical
treatment modality for symptomatic lumbar degenerative disease. this was a clinical trial study,
including 20 cases of symptomatic degenerative lumbar disease who have failed medical treatment
which includes one or more of the following: more than 40-year-old, having radiological evidence of
lumbar degenerative disease whether stable or unstable. The duration of the study ranged from 6-12
months. Oswestry Disability Index (ODI) at baseline was ranged between 42 – 80 with a mean value
of 61.65±11.380 and it was decreased significantly after 1 year of surgery with a mean value of
35.35±11.417. VAS score at baseline was ranged between 4 – 9 with a mean value of 6.80± 1.609 and
it was decreased significantly after 1 year of surgery with a mean value of 0.75±0.910. TLIF is a
technique which offers a simple, safe and effective treatment for degenerative lumbar spine disorders
with great improvement of life quality of cases with surgery satisfaction. |
