Impact of cement leakage into disks on the development of adjacent vertebral compression fractures.
A retrospective study assessing new adjacent vertebral compression fracture (VCF) after percutaneous vertebroplasty (PV). ⋯ PV is a simple and effective, but not risk-free or complication-free procedure for the treatment of osteoporotic VCF. Patients undergoing PV should be informed of the possibility of new adjacent fractures and the higher risk if cement leaks into the disk.

A Comparison of fixed-hole and slotted-hole dynamic plates for anterior cervical discectomy and fusion.
A retrospective review of clinical data at 1 institution was performed. ⋯ The use of a fixed-hole dynamic plate is more favorable in regards to graft subsidence and implant translation in the follow-up period, although clinical outcome and fusion rates are similar in patients with either the fixed-hole or slotted-hole dynamic plates.

Randomized Controlled Trial Multicenter Study Comparative StudyLower incidence of dysphagia with cervical arthroplasty compared with ACDF in a prospective randomized clinical trial.
The current study of 251 consecutive 1-level anterior cervical reconstructions was undertaken to compare the incidence of dysphagia between cervical disk replacement and conventional anterior cervical fusion and instrumentation. ⋯ In a prospective randomized clinical study the incidence of postoperative dysphagia and the long-term resolution of the dysphagia was greatly improved in the PCM group compared with the instrumented ACDF control group.

Randomized Controlled TrialTumor necrosis alpha-blocking agent (etanercept): a triple blind randomized controlled trial of its use in treatment of sciatica.
Triple blind randomized controlled study. ⋯ Small numbers of trial participants limited statistical analysis. The trend appears to show no benefit to the use of etanercept over placebo in the pharmacologic treatment of sciatica.

Can a bone marrow-based graft replacement result in similar fusion rates as rib autograft in anterior interbody fusion procedures for adolescent thoracolumbar scoliosis?
Nonrandomized consecutive case series comparing interbody spine fusion with autograft versus bone marrow-based graft replacement (BGR). ⋯ Anterior spinal fusion using bone marrow-based graft substitutes for thoracolumbar adolescent idiopathic scoliosis demonstrated equivalent results to rib autograft when used with dual-rod instrumentation and structural support. In this patient series, the rate of fusion was faster in the bone marrow-treated segments. These results suggest that for patients as described in this cohort, bone marrow-based graft replacements can thus be used as an alternative, or adjunct, to autograft to achieve interbody fusion in scoliosis surgery.
