Lumbar facet joint motion in patients with degenerative spondylolisthesis.
Controlled laboratory study. ⋯ The range of rotation decreased at the facet joints at the DLS level (L4-L5) in patients compared with those in healthy subjects and DDD patients. This decrease in range of rotation implies that the DLS disease may cause restabilization of the joint. The data may help the selection of conservative treatment or different surgical techniques for the DLS patients.

Clinical TrialTwo-year results of X-stop interspinous implant for the treatment of lumbar spinal stenosis: a prospective study.
Prospective Observational Study. ⋯ This study demonstrates with the use of ZCQ scores as primary outcome measures that improved clinical outcomes are maintained at 2 years after X-stop implantation.

Controlled Clinical TrialCost-utility analysis of minimally invasive versus open multilevel hemilaminectomy for lumbar stenosis.
Two-year cost-utility study comparing minimally invasive (MIS) versus open multilevel hemilaminectomy in patients with degenerative lumbar spinal stenosis. ⋯ MIS versus open multilevel hemilaminectomy was associated with similar cost over 2 years while providing equivalent improvement in QALYs. In our experience, MIS versus open multilevel hemilaminectomy is a cost equivalent technology for patients with lumbar stenosis-associated radicular pain.

Clinical TrialPosterior surgical correction of posttraumatic kyphosis of the thoracolumbar segment.
To analyze the clinical characteristics and surgical results of posttraumatic kyphosis of the thoracolumbar segment. ⋯ Surgical correction of posttraumatic kyphosis of the thoracolumbar segment can show good radiologic and clinical results with the appropriate procedure according to the extent of the kyphosis angle. Some patients with neurological deficit are still worthy of surgical treatment.

Clinical TrialOpen-door laminoplasty with plate fixation at alternating levels for treatment of multilevel degenerative cervical disease.
A retrospective study. ⋯ Laminoplasty with plate fixation at alternating levels is a safe, relatively fast, and cost-effective surgical method for most patients with cervical myelopathy. However, unfixed levels (C4 and C6) still have the risk of closure of open angle, which could be associated with remaining spinal cord compression. C6 is a much higher risk level compared with C4.
