Case report. ⋯ Serious neurologic deficit, especially a bladder dysfunction, caused by calcified intervertebral disc is rare. However, favorable outcome can be achieved in those cases where rapid diagnosis is made and followed by spinal cord decompression.

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.

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.

The assignment of adolescent idiopathic scoliosis (AIS) curves into curve types (1-6), as described by Lenke et al, was evaluated by 12 independent observers using the original description versus a decisional tree algorithm. ⋯ Transfer of a computer algorithm, a decision tree, to a clinical diagram improved both accuracy ofAIS classification. Algorithmic diagrams could prove beneficial to increase classification reliability due to their systematic approach.

A descriptive cadaveric study measuring arterial tension. ⋯ The results of this study would be useful for not only spinal surgery but also other vascular surgeries, particularly, in cases where patients with conditions such as atherosclerosis or stenosis.
