Segmental arteries were interrupted bilaterally at up to three levels to study the influence on spinal cord blood flow (SCBF) and function in dogs. ⋯ Interruption of bilateral segmental arteries at three levels did not damage spinal cord function in dogs, suggesting that in patients, preoperative embolization at three levels to reduce blood loss during surgery for spinal tumors would not compromise spinal cord function.

A prospective study of 100 consecutive preoperative patients with neuromuscular scoliosis whose activities and function were evaluated in a long-term follow-up. ⋯ The comparison of the preoperative and long-term follow-ups showed that patients were mostly improved. Further improvements were shown beyond the 1-year follow-up. The subjective assessments also confirmed the results. The heterogeneity of patients with neuromuscular scoliosis makes it important to evaluate the patients in subgroups and in relation to age.

Prospective, longitudinal minimum 2-year follow-up. ⋯ Single-level Prodisc lumbar total disc arthroplasty is a safe and efficacious treatment method for debilitating lumbar discogenic LBP. Significant improvements in patient satisfaction and disability scores occurred after surgery by 3 months and were maintained at the 2-year follow-up. No device-related complications occurred. Patients with severe to moderate disc height loss as well as those with symptomatic posterior anular defects with minimal disc height loss achieve functional gains and significant pain relief. Careful and appropriate patient selection is essential in ensuring optimal surgical outcomes.

Prospective, single-cohort study. ⋯ Our study found that patients are still at risk for postoperative complications as long as 1 week postoperatively and that PFTs do not return to near baseline until 1 to 2 months after surgery. The postoperative decrease in PFT should be considered during preoperative prediction of postoperative risk.

Retrospective. ⋯ Combined video-assisted thoracoscopic surgery release and posterior spinal fusion for the treatment of Scheuermann's kyphosis is a viable option for the treatment of the more severe and rigid curves.
