Multicenter Study
Variations in pelvic and other sagittal spinal parameters as a function of race in adolescent idiopathic scoliosis.
A retrospective review of clinical and radiographic data from a multicenter adolescent idiopathic scoliosis (AIS) database. OBJECTIVE.: The purpose of this study was to perform a comprehensive radiographic evaluation of the differences in pelvic parameters between 2 groups (white and black) in a scoliotic population. ⋯ In our study, significant differences were found in 3 of the 6 sagittal plane parameters between the 2 groups. With a larger PI, a larger LL is required in order maintain a neutral sagittal balance. Our results suggest that race may influence an individual's natural spinopelvic alignment, and serves as a reminder when planning surgical reconstruction for spinal deformity.

Randomized Controlled Trial Comparative Study
Is a behavioral graded activity program more effective than manual therapy in patients with subacute neck pain? Results of a randomized clinical trial.
A randomized clinical trial. ⋯ Based on this trial it can be concluded that there are only marginal, but not clinically relevant, differences between a BGA program and MT.

An in vivo clinical trial, and an in vitro cadaveric biomechanical and micromorphologic analysis. ⋯ Vertebroplasty using viscoplastic bone cement is clinically feasible and can effectively improve the vertebral strength and reduce the cement infiltration depth. The risk of cement leakage can also be decreased by using viscoplastic bone cement.

Retrospective review. ⋯ C-arm CBCT with needle path overlay for fluoroscopic guided vertebroplasty is feasible and allows for reliable unilateral therapy of both lumbar and thoracic vertebral bodies. Extrapedicular approaches were performed safely and with good accuracy of reaching the targets.

Prospective cohort study. OBJECTIVE.: Estimate the prevalence of spondylolisthesis and determine the factors associated with higher or lower prevalence among men aged 65 years or older. ⋯ Spondylolisthesis may be more common among older men than previously recognized.
