Lumbar spinal stenosis has become one of the most disabling pathologies in the elderly population.Some additional conditions such as foraminal stenosis or degenerative spondylosis with a history of back pain and leg pain must be considered before treatment.A completely appropriate protocol and unified management of spinal stenosis have not yet been well defined.The objective of this literature review is to provide evidence-based recommendations reflected in the highest-quality clinical literature available to address key clinical questions surrounding the management of degenerative lumbar spinal stenosis.Cite this article: Covaro A, Vilà-Canet G, García de Frutos A, Ubierna MT, Ciccolo F, Caceres E.

The raise of intradiscal pressure at the adjacent segment to a rigid instrumented segment can be reduced when the rigid construct is augmented with a dynamic stabilization device. Hybrid constructs might have a possible protecting role preventing the occurrence of degenerative disc changes at the adjacent segment to a rigid instrumented level. Augmentation with a dynamic stabilization device might protect the disc above a rigid rod pedicle screw construct.

Background: The objective of this study is to compare surgical results (pain, function, and satisfaction) between a group of depressed patients and a nondepressed group who had been operated on for a degenerative lumbar condition.Methods: Prospective observational study. Preoperative pain (lumbar and radicular visual analog scale [VAS]), function (Oswestry Disability Index [ODI]), and depression (Zung depression scale) data were collected in patients listed to be operated on for a lumbar degenerative condition. One year postoperatively, ODI and VAS data were collected again as well as a satisfaction question (are you satisfied with the surgical results? Yes/no).Results: Ninety-seven patients were included in the study, 78 nondepressed patients (80.4%) and 19 depressed patients (19.6%). Preoperatively, depressed patients had more lumbar pain (P ¼ .00) and more functional limitation (P ¼ .01) than nondepressed patients. One year postoperatively, depressed patients had more radicular pain (P ¼ .029) and more functional limitation (P ¼ .03) than non-depressed patients. The overall improvement of pain and function was similar between both groups (not significant). Seventy percent of depressed patients and 80% of nondepressed patients were satisfied with the surgical outcome (P ¼ .52) 1 year postoperatively.Conclusion: Depressed patients experience the same overall level of improvement as nondepressed patients, despite having more pain and functional limitation preoperatively and 1 year after elective lumbar spine surgery than nondepressed patients. The level of satisfaction does not differ significantly between the two groups.

Patients' expectations remained very high despite having had a failed previous surgery for the same procedure.
