Randomized Controlled Trial
No difference in 9-year outcome in CLBP patients randomized to lumbar fusion versus cognitive intervention and exercises.
To compare the 9-year outcome in patients with chronic low back pain treated by instrumented lumbar fusion versus cognitive intervention and exercises. ⋯ The outcome at 9 years was not different between instrumented lumbar fusion and cognitive intervention and exercises.

Alström syndrome (AS) is a rare autosomal recessive genetic disorder with multisystemic involvement characterised by early blindness, hearing loss, obesity, insulin resistance, diabetes mellitus, dilated cardiomyopathy, and progressive hepatic and renal dysfunction. The clinical features, time of onset and severity can vary greatly among different patients. Many of the phenotypes are often not present in infancy but develop throughout childhood and adolescence. Recessively inherited mutations in ALMS1 gene are considered to be responsible for the causation of AS. Musculoskeletal manifestations including scoliosis and kyphosis have been previously described. ⋯ Here, we present a patient with AS who presented with cervical myelopathy due to extensive flowing ossification of the anterior and posterior longitudinal ligaments of the cervical spine resulting in cervical spinal cord compression. The presence of an auto-fused spine in an acceptable sagittal alignment, in the background of a constellation of medical comorbidities, which necessitated a less morbid surgical approach, favored a posterior cervical laminectomy decompression in this patient. Postoperatively, the patient showed significant neurological recovery with improved function. Follow-up MRI showed substantial enlargement of the spinal canal with improved space available for the spinal cord. The rarity of the syndrome, cervical myelopathy due to ossified posterior longitudinal ligament as a disease phenotype and the treatment considerations for performing a posterior cervical decompression have been discussed in this Grand Rounds' case presentation.

Symptomatic thoracic disc herniations (TDHs) are uncommon and can be surgically treated. Although transthoracic decompression is considered the gold standard, it is associated with significant comorbidities. In particular, approach via a posterior laminectomy has been associated with poor results. Several strategies have been developed for the resection of TDHs without manipulating the spinal cord. We describe a minimally invasive technique by using 3-D navigation and tubular retractors with the aid of a robotic holder via an oblique paraspinal approach. ⋯ The oblique paraspinal approach may offer an alternative surgical option for treating TDHs.

Congenital cervical stenosis (CCS) occurs when the bony anatomy of the cervical canal is smaller than expected in the general population predisposing an individual to symptomatic neural compression. No studies have defined CCS based on the normal population. The diagnosis is currently made based on clinical impression from radiographic studies. The aim of this study is to establish parameters that are associated with CCS, based on anatomic measurements on a large sample of skeletal specimens. ⋯ Based on our study of a large population of adult skeletal specimens, we have defined CCS at each level. Values of SCD < 13 mm and IPD < 23 mm are strongly associated with the presence of CCS at all levels.

To investigate the incidence and risk of stroke after lumbar spinal fusion surgery. ⋯ Three years post-operatively, patients who received lumbar spinal fusion had stroke incidence rates similar to those without surgery. Posterior lumbar spinal fusion surgery is not associated with increased risks for any kind of stroke.
