Clinical Trial
Radiolucent cage for cervical vertebral reconstruction: a prospective study of 17 cases with 2-year minimum follow-up.
In cervical spondylotic myelopathy, extended anterior spinal cord decompression necessitates subsequent stable vertebral reconstruction. Reconstruction with an iliac crest graft and screw-plate fixation gives satisfactory clinical and radiological results, but they are often compromised by morbidity involving the bone harvest. The purpose of this study was to evaluate the contribution to cervical reconstruction of a biocompatible, radiolucent cage combined with screw-plate fixation, making use of bone harvested in situ. ⋯ The cases of probable non-fusion and screw breakage were not accompanied by signs of instability on the flexion extension films. This cage meets the biologic and biomechanical imperatives of cervical reconstruction. It obviates complications involving bone harvest.

Spinal cord injury (SCI) results in the loss of function below the lesion. Secondary injury following the primary impact includes a number of biochemical and cellular alterations leading to tissue necrosis and cell death. Methylprednisolone (MP), by reducing edema and protecting the cell membrane against peroxidation, is the only pharmacological agent with a proven clinically beneficial effect on SCI. ⋯ Although combined treatment was significantly more effective on lipid peroxidation than melatonin or MP treatments alone, at the 10th day, neurobehavioral, electrophysiological, and ultrastructural recovery were at the same level. In conclusion, MP, melatonin, and MP and melatonin combined treatment modalities improved functional recovery at the same level. Future studies involving different doses of melatonin and different dose combinations with MP could promise better results since each drug has a different anti-oxidative mechanism of action.

Given the high prevalence rates of back pain, as early as in childhood, there has been a call for early preventive interventions. To determine which interventions are used to prevent back problems in schoolchildren, as well as what the evidence is for their utility, the literature was searched to locate all investigations that used subjects under the age of 18 and not seeking treatment. Included investigations were specifically designed as an intervention for low back pain (LBP) prevention. ⋯ On the other hand, since the literature shows that back-pain reports about schoolchildren are mainly associated with psychosocial factors, the scope for LBP prevention in schoolchildren may be limited. However, schoolchildren are receptive to back-care-related knowledge and postural habits, which may play a preventive role for back pain in adulthood. Further studies with a follow-up into adulthood are needed to evaluate the long-term effect of early interventions and the possible detrimental effect of spinal loading at young age.

Degenerative spondylolisthesis of the cervical spine is rare. Patients show signs of progredient myelopathy, radiculopathy and pain. Treatment strategies include ventral, dorsal and combined fusion techniques with or without repositioning and decompression. ⋯ The aims of treatment for cervical spondylolisthesis are spinal cord decompression (ventral, dorsal or both), correction and fusion. The used procedure should depend on the severity of the cervical deformity, degree and side of the spinal cord compression, and the possibility of correction by extension and positioning.
