Lomber spinal stenosis

Transforaminal epidural steroid injection

Injections for lomber spinal stenosis • Caudal • Interlaminar • Unilateral foraminal • Faset block

Aim: • Study Design: Retrospective study • Bilateral transforaminal steroid injections to lomber spinal stenosis (LSS) cases (One or two level) With neurogenic claudication (NC) With sciatic pain With low back pain

Material and Method • 65 patient (Mean age=54, 2± 12, 6; age distribution=42 -68) • 87 levels (174 BLTFEIs) • August 2015 – January 2018 • Visual analog scale(VAS) 0, 1, 3, 6 months Low back pain Sciatic pain • Oswetry disability index (ODI) 0, 1, 3, 6 months Quality of life • Walking distance 0, 1, 3, 6 months Neurogenic claudication

Results • Substantial responders • VAS (Amelioration > 5 points) Low back pain Sciatic pain Substantial Responders (%) 45 40 41, 5 35 35, 6 30 30, 7 25 28, 5 27, 7 20 17, 5 15 10 5 0 0. month 1. month 3. month LBP SP 6. month

Conclusion • BLTFSIs in LSS • Noneffective in neurogenic claudication • Effective in amelioration quality of life • Significantly in 1. and 3 months • Relatively in 6. month • Effective in LBP and SP • More effective in SP than LBP
