Threaded cortical bone dowels for lumbar interbody fusion: over 1-year mean follow up in 28 patients.

摘要: Object. The authors retrospectively reviewed a series of 35 patients with mechanical low-back or one- to two-level discogenic pain; the underwent lumbar interbody fusion in which threaded cortical bone dowels (TCBDs) were placed treat degenerative disc disease. purpose study was delineate rates and outcome data this patients. Methods. composed 18 women 17 men whose mean age 46 years (range 17–76 years). There nine active cigarette smokers. All presented symptoms consistent pain, magnetic resonance imaging revealed changes related collapse at one two vertebral levels. For placement TCBDs, 23 posterior (PLIF), whereas 12 anterior (ALIF). In all except patient undergoing PLIF, pedicle screw rod constructs used without posterolateral fusion. p...
