Comparative Study
Anterior and posterior lumbar interbody fusion with percutaneous pedicle screws: comparison to muscle damage and minimally invasive techniques.
Retrospective analysis of patients whom underwent one-level anterior lumbar interbody fusion or posterior lumbar interbody fusion with percutaneous pedicle screws. ⋯ Minimally invasive anterior lumbar interbody fusions with percutaneous pedicle screws cause significantly less muscle damage than minimally invasive posterior lumbar interbody fusions with percutaneous screws. Furthermore minimally invasive anterior lumbar body interbody fusions demonstrated near the same amount of muscle damage to previously published literature on lumbar microdikectomies.

A descriptive study (based on skeletal material) was designed to measure sacral anatomic orientation (SAO) in individuals with and without spondylolysis. ⋯ A more horizontally oriented sacrum leads to direct impingement on L5 pars interarticularis by both L4 inferior articular facet superiorly and S1 superior articular facet inferiorly. Repetitive stress due to standing (daily activities) or sitting increases the "pincer effect" on this area, and eventually may lead to incomplete synostosis of the neural arch.

A prospective clinical study. ⋯ The lumbar extension test has no predictive value for the outcome after surgical treatment of LSS.

Case report. ⋯ Venous congestive myelopathy due to arteriovenous shunting or unrecognized syrinx are presented as possible etiologies of this patient's spinal cord injury. A preoperative MRI may have helped discern the cause of this patient's spinal cord injury.

Analysis of spine-related websites available to the general public. ⋯ Our findings suggest that most of the Spine-related patient education materials on professional society and practice-based websites have readability scores that may be too high, making comprehension difficult for a substantial portion of the United States adult population.
