ee mj, bransford rj, bellabarba c, chapman jr, cohen am, harrington rm, et al: the effect of bilateral laminotomy versus laminectomy on the motion and stiffness of the human lumbar spine: a biomechanical comparison.

Respuesta :

To check variations in movement styles and lumbar backbone stiffness after bilateral laminotomy as opposed to laminectomy.

Summary of heritage information Spondylolisthesis after facet-sparing laminectomy has been mentioned with a frequency of 8% to 31%. Bilateral laminotomies had been proven to be powerful in decompressing the backbone, with out resection of the posterior osteo-ligamentous complex. We hypothesize that bilateral laminotomies set off appreciably much less androgenic hypermobility and much less stiffness discount than a conventional facet-sparing laminectomy withinside the lumbar backbone.

These information display that bilateral laminotomies set off appreciably much less hypermobility and much less stiffness discount in comparison with a complete laminectomy. The renovation of the critical posterior osteo-ligamentous systems can also additionally offer a stabilizing impact in stopping postdecompression spondylolisthesis.
