Comparative Study Clinical Trial
Transforaminal lumbar interbody fusion versus anterior lumbar interbody fusion as an adjunct to posterior instrumented correction of degenerative lumbar scoliosis: three year clinical and radiographic outcomes.
Prospective, nonrandomized consecutive single surgeon series. ⋯ With current deformity correction techniques, both ALIF and TLIF are effective in DLS surgery. Anterior surgery is not routinely required to treat all cases of DLS.

Comparative Study
Adult scoliosis in patients over sixty-five years of age: outcomes of operative versus nonoperative treatment at a minimum two-year follow-up.
Retrospective case-control study. ⋯ Adult scoliosis patients over the age of 65 years treated operatively had significantly less pain, a better health-related quality of life, self image, mental health, and were more satisfied with their treatment than patients treated conservatively. However, we found no statistically significant differences in their degree of disability as measured by the ODI as well as physical and mental health by the SF-12 instrument. Preoperative radiographic deformity was not determined to be a significant factor for predicting whether an operative or nonoperative treatment course was chosen.

A three-dimensional, nonlinear finite element analysis was performed to predict the in situ contact interaction of prosthesis components of the Prodisc-L in a multisegmental lumbar model following total disc replacement (TDR). ⋯ The in situ function of the TDR prosthesis was highly dependent on how well the device could incorporate itself into the mechanical environment in the disc space, which has been determined by the rest of the spinal structures, including the retained disc anulus, articular facets, ligaments, vertebrae, and muscular stabilizers. The different contact interaction of the artificial disc components revealed here could be attributed to the violation of this mechanical environment which, in turn, may bring adverse effects to those spinal elements.

Retrospective study of 20 consecutive patients who underwent en bloc tumor excision of sacral chordomas and chondrosarcomas. ⋯ Wide or marginal en bloc excision of sacral chordoma and chondrosarcoma is associated with significant improvement in disease-free survival with acceptable perioperative morbidity rate.

A long-term, population based, retrospective follow-up study. ⋯ Brace treatment does not prevent progression of the spinal deformity in patients with DD. Anteroposterior surgery is indicated in patients with severe spinal deformities. The risk for major complications is high especially in patients with marked kyphosis.
