A case-control study using radiograph findings and the PCR assay with regard to the susceptibility and the severity of ossification of posterior longitudinal ligament of the spine (OPLL). ⋯ The present results suggest that the IVS20-11delT variant of the NPPS gene and the A861G variant of the leptin receptor gene are associated with more extensive OPLL, but not with the frequency with which it occurs.

The authors evaluated a case series of 5 patients with cerebral palsy and a previously placed subcutaneous reservoir for continuous intrathecal baclofen infusion to control spasticity who underwent spinal arthrodesis with posterior instrumentation for progressive neuromuscular scoliosis deformities. ⋯ Low pressure headaches resulting from a cerebrospinal fluid leak following catheter reinsertion may occur in the postoperative period. Preoperative concerns with the baclofen pump reservoir placed subcutaneously and pressure sores were not seen with careful prone positioning on a 4-poster frame. Progression of scoliosis in patients with cerebral palsy requiring spinal arthrodesis was demonstrated in 4 of the patients after continuous intrathecal baclofen was started. The progression of the spinal deformity as a consequence of growth, natural history, or the intrathecal baclofen infusion is unknown at the present time.

To assess the effects of acupuncture and dry-needling for the treatment of nonspecific low back pain. ⋯ The data do not allow firm conclusions regarding the effectiveness of acupuncture for acute low back pain. For chronic low back pain, acupuncture is more effective for pain relief and functional improvement than no treatment or sham treatment immediately after treatment and in the short-term only. Acupuncture is not more effective than other conventional and "alternative" treatments. The data suggest that acupuncture and dry-needling may be useful adjuncts to other therapies for chronic low back pain. Because most of the studies were of lower methodologic quality, there is a clear need for higher quality trials in this area.

Comparative Study
Long-term outcomes of surgical and nonsurgical management of lumbar spinal stenosis: 8 to 10 year results from the maine lumbar spine study.
A prospective observational cohort study. ⋯ Among patients with lumbar spinal stenosis completing 8- to 10-year follow-up, low back pain relief, predominant symptom improvement, and satisfaction with the current state were similar in patients initially treated surgically or nonsurgically. However, leg pain relief and greater back-related functional status continued to favor those initially receiving surgical treatment. These results support a shared decision-making approach among physicians and patients when considering treatment options for lumbar spinal stenosis.
