Clinical outcome and quality of life were then analyzed in a retrospective study. METHODS: Thirty patients with a mean age of 43 years (range, 26-63) who suffered from instability of levels L4-L5 (n = 23), L5-S1 (n = 3), or both (n = 2) underwent surgery. Spondylodesis was ...
An ALIF is done in the lumbar, or lower, spine. Most commonly it is performed on the L4 through L5 or L5 through S1 segment at the bottom of the lumbar spine, as these segments are most likely to break down. A...
Lumbar spine - Anterior approach - Interbody fusionSurgical PrinciplesAfter resection of the anulus fibrosus through a retroperitoneal approach the vertebrae adjacent to the disc are stripped of periosteum on their anterior and lateral surfaces and bone grafting is extended to these areas. This allows ...
So, few days back he scheduled me for some spine fusion surgery. The operation should be done in a week. I'm not afraid of operation or anything, but I would really like to hear more about recoup after operation. How long will it take to heal and for me to recover completely?
The L4-L5 level was the most difficult level to fuse and the most difficult to interpret using x-rays. Patients with persistent back pain, when nonmechanical causes have been ruled out, should be considered for surgical exploration of the fusion mass even if x-rays appear to indicate a ...

directly compare the efficacy of NELL-1, a novel osteoinductive growth factor, to two currently available treatments, (1) recombinant BMP-2 and (2) iliac crest bone grafting, in a spinal fusion model.Twenty-six skeletally mature athymic rats underwent posterolateral spine fusion of L4/L5 ...
Inf l uence of posterior pedicle screw fi xation at L4–L5 level on biomechanics of the lumbar spine with and without fusion: a f i nite element methodEmre Sengul 1,4* , Ramazan Ozmen 2 , Mesut Emre Yaman 3 and Teyf i k Demir 1 BackgroundLow-back pain is a commonly faced phenome...
In a previous study, our team evaluate the biomechanics effect of the modified cortical bone trajectory (MCBT) technique with other traditional internal fixation systems by comparing the von Mises stress, displacement, von Mises stress on L4–L5 segment of the lumbar spine using numerical simulation...
Recent interest in laparoscopic spine surgery using threaded cages has resulted in questions regarding the ability to safely access the L4-L5 disc using this approach. The laparoscopic transperitoneal approach to L5-S1 is below the bifurcation of the great vessels, thus requiring minimal mobilization ...
