Randomized Controlled Trial Multicenter Study
ProDisc-C and anterior cervical discectomy and fusion as surgical treatment for single-level cervical symptomatic degenerative disc disease: five-year results of a Food and Drug Administration study.
Randomized controlled trial. ⋯ Five-year results show that TDR with ProDisc-C is a safe and effective treatment of single-level symptomatic cervical disc disease. Clinical outcomes were comparable with ACDF. ProDisc-C patients maintained motion at the index level and had significantly less neck pain intensity and frequency as well as a lower probability of secondary surgery.

Propensity score-adjusted prospective cohort study. ⋯ After adjusting for confounders using propensity score matching and multivariate logistic regression analysis, patients undergoing outpatient lumbar discectomy had lower overall complication rates than those treated as inpatients. Surgeons should consider outpatient surgery for lumbar discectomy in appropriate candidates.

Case Reports
Neurological outcome and management of pedicle screws misplaced totally within the spinal canal.
This study reports 9 cases referred to our institution after surgical correction of adolescent idiopathic scoliosis and pedicle screws misplaced totally within the spinal canal. ⋯ Improper pedicle screw placement can lead to neurological complications appearing early or late (after 2 yr). Late neurological complications were associated with screw loosening in 2 cases. The authors strongly recommend removal of any pedicle screw misplaced totally within the spinal canal due to the risk of early or late neurological complications, regardless of the severity of spinal canal intrusion.
