Isthmic spondylolisthesis (IS) is the most common spondylolytic disorders and one of the most common causes of low back pain and sciatica in adolescents and adults. Although the initial management is conservative, surgery is often the ultimate solution. Interbody fusion has been found superior and replaced the gold standard postero-lateral fusion. Transforaminal Lumbar Interbody Fusion (TLIF) has been associated with fewer complications and has become the choice of surgery. This study was done to evaluate the clinical, radiological and functional outcome of TLIF in Low Grade Isthmic Spondylolisthesis (LGIS). The clinical records of 46 consecutive patients within the age range of 31 to 60 years, who had symptomatic unstable Low Grade Isthmic Spondylolisthesis (LGIS) with or without unilateral radiculopathy in Bangabandhu Sheik Mujib Medical University (BSMMU) and private settings, from April 2007 to March 2012 were reviewed with 2 year completed follow-up. Patients were evaluated for pain by Visual Analogue Score (VAS), Disability by Oswestry Disability Index (ODI), radiological fusion by Brantigan and Steffee criteria, reduction of listhesis by Taillard’s method and the overall functional outcome by the Macnab’s criteria. Pain (Low back and leg), disability, neurological status had highly significant (p<0.001, paired t test) improvement. Forty two (91.30%) cases achieved satisfactory radiological fusion with overall 30% reduction of slip. Satisfactory outcome was reached in 45(97.83%) cases. Transforaminal Lumbar Interbody Fusion results in significant improvement of clinical, radiological and functional debility of symptomatic LGIS in adults.
