Inception cohort study. ⋯ During a period of 3 months, 24% of the patients had not recovered. Psychological factors and neurological signs were strongly associated with nonrecovery at 3 months. In addition to the traditional examination of neurological symptoms and signs, psychological factors should be considered already at the initial visit of an episode of low back pain.

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.

A retrospective review of spinal deformity in patients with congenital heart disease surgically treated through a median sternotomy before the age of 8 years. Assessment was done on chest roentgenograms at skeletal maturity. ⋯ There is a high prevalence of scoliosis in patients with congenital heart disease surgically treated through a median sternotomy. The prevalence of scoliosis increases in patients operated at an earlier age.

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.

Comparative Study
Long-term outcome of laminoplasty for cervical myelopathy due to disc herniation: a comparative study of laminoplasty and anterior spinal fusion.
A retrospective study was conducted. ⋯ Because the 2 procedures provided the same neurologic improvement, the risks of bone graft complication with ASF must be weighed against the risks of chronic neck pain associated with laminoplasty for determining the best technique. Therefore, because our present surgical strategy for cervical myelopathy due to disc herniation, laminoplasty is the procedure of choice except for a patient with single level disc herniation without developmental canal stenosis, who is considered to be a good candidate for ASF.
