Retrospective study. ⋯ Distal fusion level should be extended to at least lower end vertebra (LEV) -1 in type 1A-A and type 1A-D curves, while it might be necessary to go down to LEV in the type 1A-B and 1A-C. It seems that LEV might be a reliable guide to select ideal distal fusion level in Lenke type 1A curves.

An in vivo study to develop a goat large-animal model for intervertebral disc (IVD) degeneration. ⋯ A comparison of the various injuries inflicted showed that the use of a 4.5-mm drill bit resulted in the most significant histologic changes.

We performed a retrospective chart review of patients with nonadolescent idiopathic scoliosis who underwent open vertebral stapling for treatment of spinal deformity. ⋯ More than half of the patients in our series have undergone or are scheduled to undergo further spinal surgery, at an average of 2 year after anterior vertebral stapling. It is unclear if progression may be related to the young age at surgery, the relatively severe average preoperative curve magnitude, the nature of the underlying scoliosis, or a combination of these.

Cohort study. ⋯ Among men without history of back disease reporting of frequent exposure to strenuous physical activity at work was a strong risk factor for later hospitalization due to HLDD.
