A cross-sectional magnetic resonance imaging study with questionnaires on low back pain (LBP) and functional limitations. ⋯ Intervertebral DD was associated with low back symptom severity among young adults, suggesting that the symptoms may have a discogenic origin at this age. However, DD was also found in one-third of asymptomatic subjects.

One-year prospective study of 141 acute whiplash patients (WLP) and 40 acute ankle-injured controls. ⋯ The Risk Assessment score is suggested as a valuable tool for grading WLP early after injury. It has reasonable screening power for encountering work disability and reflects the biopsychosocial nature of whiplash injuries.

Prospective analysis of preoperative and postoperative radiological data. ⋯ After classic Hirabayashi open-door laminoplasty, opened laminae showed reclosure at 6 months, with approximately 10% decrease in AP diameter and opening angle. Postoperative lamina closure was associated with recurrent spinal cord compression, suggesting the need for other augmenting techniques that keep the laminae opened.

Retrospective subgroup analysis of prospectively collected data according to treatment received. ⋯ Patients with SS with fewer than 12 months of symptoms experienced significantly better outcomes with surgical and nonsurgical treatment relative to those with symptom duration greater than 12 months. There was no difference in the outcome of patients with degenerative spondylolisthesis according to symptom duration.

Radiological analysis and classification of normal patterns of sagittal alignment of the spine. ⋯ The patterns of sagittal alignment could be classified into three types showing that the spinal balance becomes more negative, the lumbar inclination and TLJA increase, the SS and pelvic incidence decrease, and lumbar lordotic curves becomes shorter as the patterns of sagittal curvature move toward type 3. This classification in young adults should be considered individually as a reference for surgeons aiming to restore the lumbar lordosis and sagittal alignment in degenerative lumbar fusion surgery.
