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.

Retrospective study of 55 consecutive patients with spinal metastases secondary to breast cancer who underwent surgery. ⋯ The modified Tokuhashi score assists in decision making based on reliable estimators of life expectancy in patients with spinal metastases secondary to breast cancer.

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.

A retrospective study was conducted to review the complication of cage migration in posterior lumbar interbody fusion (PLIF) with the Bagby and Kuslich method. ⋯ An 8% rate of cage migration was found in the current study, and 4 of 7 cases with cage migration received revision surgery. Several factors may contribute to the cage migration, including lack of posterior instrumentation and total facetectomy. Revision surgery for cage migration was technically challenging.
