Questionnaire survey on leg cramps for patients with lumbar spinal canal stenosis (LCS). ⋯ LCS patients had significantly more frequent attacks of nocturnal leg cramps than the control population, and leg cramps disturbed the quality of the patients' life, and they rarely improved after decompression surgery. Leg cramps should be recognized as one of the symptoms of LCS, which disturb the patients' quality of life.

Single-center retrospective study. ⋯ Obese and morbidly obese patients have multiple comorbidities, and the spinal surgeon should be prepared to encounter perioperative complexities. Operative times are longer in comparison with normal weight patients with a higher incidence of postoperative complications. No weight loss occurs after spinal surgery.

Retrospective cohort study supplemented by analysis of postmortem spinal cord tissue. ⋯ Hyponatremia is common in the early stage post-SCI. Our results also suggest that hyponatremia is associated with the integrity of descending renal sympathetic circuits which mediate the renin-angiotensin response to neural injury, in the setting of neurogenic hypotension with cardiovascular dysfunction.

This in vitro human cadaveric study tested the loss of thoracic motion segment flexion stiffness after sequential posterior upper instrumented vertebra anchor placement techniques and posterior column destabilization. ⋯ Posterior thoracic skeletal structures involved in upper instrumented vertebra exposure andanchor placement were found to contribute to adjacent segment flexion stiffness. Although stiffness loss was small after individual procedures, the effects were additive for routinely used combinations.

Retrospective. ⋯ Intraoperative CSF leak was encountered in 6.3% of patients undergoing CC for OPLL. A successful repair was achieved using fascial graft, gelatin sponge, lumbar CSF drainage, and bed rest.
