Comparative StudyIs there a difference between simultaneous or staged decompressions for combined cervical and lumbar stenosis?
We evaluated 43 patients diagnosed with tandem spinal stenosis (TSS) from 1999 to 2005 in an academic hospital. ⋯ These results indicate that TSS can be effectively managed by either surgical intervention, simultaneous, or staged decompressions. However, patient age, blood loss, and operative time do significantly impact outcomes. Therefore, operative management should be tailored to the patient's age and the option which will limit blood loss and operative time, whether that is by simultaneous or staged procedures.

Multilevel lumbar spinal stenosis decompression: midterm outcome using a modified hinge osteotomy technique.
A prospective cohort study was carried out looking at the functional outcome and post procedure translational segmental instability after multi-level lumbar decompression using a hinge osteotomy technique. ⋯ Decompression of multi-level lumbar spine stenosis using the unilateral approach with the hinge osteotomy technique is a safe approach for multi-level stenosis, with good outcome and no evidence of significant segmental translational spinal instability.

Extreme lateral interbody fusion approach for isolated thoracic and thoracolumbar spine diseases: initial clinical experience and early outcomes.
Retrospective review of prospective collected data on 22 patients. ⋯ The XLIF technique can be expanded to treat diseases in the thoracic spine. Although the magnitude of deformity correction achieved is less than that of the traditional open approaches, the lesser invasiveness of this technique may be tolerable for the elderly and in patients with significant medical comorbidities.

Randomized Controlled Trial Comparative StudySagittal alignment comparison of Bryan disc arthroplasty with ProDisc-C arthroplasty: a prospective, randomized controlled clinical trial.
A prospective, randomized study of the radiographic outcomes in patients undergoing single-level cervical arthroplasty with Bryan disc and ProDisc-C prosthesis. ⋯ Bryan disc arthroplasty with modified techniques can maintain the lordosis of FSU, whereas ProDisc-C arthroplasty can restore the lordosis of FSU. For the patients with preoperative FSU kyphosis, ProDisc-C arthroplasty may be a better choice to restore the lordosis.

Comparative expression of matrix-associated genes and inflammatory cytokines-associated genes according to disc degeneration: analysis of living human nucleus pulposus.
The 2 groups of living human nucleus pulposus were prospectively compared according to disc degeneration. ⋯ Mildly degenerated discs showed greater matrix, chondrogenic, and osteoblastic gene expressions than severely degenerated discs, indicating that the ability to produce matrix-associated proteins is greater for cells in mildly degenerated than in severely degenerated discs. However, inflammatory cytokine genes associated with disc degeneration were expressed at higher levels in the severely degenerated group. This study shows that a reduction in matrix synthesis and an increase of inflammatory cytokine levels occurs during disc degeneration at the same time.
