ANTERIOR ENDOSCOPIC L5-S1 INTERBODY SPINAL FUSION – LONG-TERM OUTCOME STUDY L5-S1 interbody fusion is a successful technique for treating patients with isolated degenerative disc disease. Traditionally through an open technique, the anterior laparoscopic approach for this was first described in 1991.The...
In an MRI study the measurements of the cross-sectional area of the neuroforamen of L4/5 and L5/S1 in neutral position, segmental distraction and compression were calculated. Nine cadaver specimens were investigated and the foraminal width of L4/5 and L5/S1 was measured. In both segments of...
