In 2001, several myths of low back pain still were alive in the general population in Norway, myths that were not in concordance with current guidelines. ⋯ In Norwegian general practitioners and physiotherapists, Deyo's 7 myths mostly seem to be dead and buried. However, it does not seem that this has extended to the public yet, as many myths still are alive in the general population.

The authors reviewed a series of nontraumatic spinal cord injuries associated with surfing lessons. ⋯ Surfer's myelopathy is a nontraumatic paraparesis/paraplegia that affects first-time surfers. Although most patients have a complete or near-complete recovery, complete paraplegia has occurred.

A retrospective study of 43 consecutive patients who underwent percutaneous endoscopic lumbar discectomy for recurrent disc herniation. ⋯ Percutaneous endoscopic lumbar discectomy is effective for recurrent disc herniation in selected cases. The posterolateral approach through unscarred virgin tissue can prevent nerve injury and could preserve the spinal stability. Both foraminal and intracanalicular portions can be decompressed simultaneously.

Comparison of occlusion of lumbar arteries in magnetic resonance angiography (MRA) with patient-reported sciatica symptoms during a 3-year follow-up. ⋯ Arterial stenosis is associated strongly and consistently with patient-estimated physical ability,but only slightly with subjective pain symptoms. Interestingly, new stenosis is preceded by pain symptoms. The evaluation of lumbar blood flow may thus be useful in clinical practice.

Measurements of the length of pediculocorporeal screw trajectory were performed on bony sacra. Outer interforaminal distances of the first sacral vertebra were measured on bony sacra and anteroposterior sacral radiographs. ⋯ In this study, we described an easy and a reliable method to determine the length of anteromedial screw by measuring outer interforaminal distance of S1 vertebra on anteroposterior radiograph of the sacrum.
