Multicenter Study Comparative Study
Postoperative improvement in health-related quality of life: a national comparison of surgical treatment for focal (one- to two-level) lumbar spinal stenosis compared with total joint arthroplasty for osteoarthritis.
The results of single-center studies have shown that surgical intervention for lumbar spinal stenosis yielded comparable health-related quality of life (HRQoL) improvement to total joint arthroplasty (TJA). Whether these results are generalizable to routine clinical practice in Canada is unknown. ⋯ Significant improvement in physical HRQoL after surgical treatment of FLSS (including DLS) is consistently achieved nationally. Our overall results demonstrate that a comparable number of patients can expect to achieve MCID and SCB 2 years after surgical intervention for FLSS and total knee arthroplasty.

Diffuse idiopathic skeletal hyperostosis (DISH) is a common but underdiagnosed condition relating to ossification of spinal ligaments that can cause compression of the esophagus and trachea. According to case reports, dysphagia or airway obstruction resulting from DISH is a rare occurrence. ⋯ Diffuse idiopathic skeletal hyperostosis as a cause of dysphagia and/or airway obstruction may be an increasing and underappreciated phenomenon. Diffuse idiopathic skeletal hyperostosis should be included in the differential diagnosis of dysphagia and airway obstruction.

Randomized Controlled Trial
Disc height and motion patterns in the lumbar spine in patients operated with total disc replacement or fusion for discogenic back pain. Results from a randomized controlled trial.
Fusion is considered the "gold standard" in surgical treatment of degenerated disc disease; the intended postoperative goal is absence of mobility, but treatment may induce degeneration in adjacent segments. Total disc replacement (TDR) aims to restore and maintain mobility by replacing a painful disc. Little is known about the degree and quality of mobility in artificial discs in vivo and whether maintained mobility reduces the stress on adjacent segments that is believed to occur after fusion. ⋯ This very accurate X-ray method (DCRA) indicates that surgical goals were reached in most patients. This, however, was not correlated to clinical outcome. Differences between the groups in postoperative disc height at treated segments, respective ROM, and translation at adjacent segments did not affect the clinical outcome after 2 years.

Although the frequency of transpsoas lumbar interbody fusion procedures has increased in recent years, complication reports remain scarce in the literature. ⋯ Fracture can occur after transpsoas lumbar interbody fusion, even in nonosteoporotic patients. Factors, such as intraoperative end-plate breach, subsidence, compression by lateral screws, and cage rolling, could contribute to the development of fractures after transpsoas interbody fusion.
