Comparative StudyMonosegmental transpedicular fixation for selected patients with thoracolumbar burst fractures.
A prospective cohort study on selected consecutive patients. ⋯ For selected thoracolumbar burst fractures, MSPI can provide the same or better fixation and preserve more motion segments than other methods of posterior pedicle instrumentation. With preoperative evaluation using the spinal LSC system, MSPI is effective and reliable for the treatment of thoracolumbar burst fractures when properly indicated.

Comparative StudyDirect lateral lumbar interbody fusion for degenerative conditions: early complication profile.
A community hospital prospective, nonrandomized chart review. March 2004 to December 2006, 58 patients were treated. Adverse events: new complaints and increasing length of stay limit early mobilization and require consultation with other physicians or reoperation. These formed the focus of the study. ⋯ Major adverse events approximated 8.6% with approach-related complaints of nerve irritation nearing 3.4%. Mild complications occurred in 13.7% of patients. Meralgia paresthetica was a primary approach-related complaint. Most complaints significantly reduced by first postoperative visit. One patient (1.7%) had symptoms lasting over a year that did not adversely affect function. Significant finding related to exposure, that is, 1-versus 2-level cases. Overall morbidity reduction noted by EBL is considerably less compared with the historical cohort. Direct lateral lumbar interbody fusion has proven to be of value.

Comparative StudyAn evaluation of information on the Internet of a new device: the lumbar artificial disc replacement.
An analysis of websites, accessible to the public, was conducted pertaining to the lumbar artificial disc replacement. ⋯ The results of this study demonstrate that much of the content of Internet-derived information pertaining to the lumbar artificial disc replacement is potentially misleading. Until long-term data are available, patients should be cautioned when using the Internet as a source for health care information, particularly with regard to the lumbar artificial disc replacement.

Comparative StudyDynamic evaluation of the spinal cord in patients with cervical spondylotic myelopathy using a kinematic magnetic resonance imaging technique.
This prospective study analyzed preoperative and postoperative dynamic changes of the spinal cord in patients with cervical spondylotic myelopathy. ⋯ Cord distances are relatively smaller at C4/5 and C5/6 levels, resulting in a narrowing of the posterior subarachnoid space with posterior cord compression in patients with cervical spondylotic myelopathy. The outcome of surgery was not correlated with the magnitude of postoperative backward shifting of the spinal cord, although the spinal cord of patients after posterior decompression moved significantly dorsally at any of the flexed, neutral, or extended spinal positions. Thus numerous factors might affect the postoperative outcomes.

Comparative StudyCurrent trends in spinal arthroplasty: an assessment of surgeon practices and attitudes regarding cervical and lumbar disk replacement.
Survey study involving orthopedic and neurosurgical spine surgeons. ⋯ Although the results of this study confirm that the enthusiasm for TDA was shared by many of these respondents, it is clear that additional long-term, prospective, comparative data are required before this technology may be considered as a replacement for more traditional spinal fusion procedures.
