Biological non-ablative repair of lumbar discs by transforaminal intradiscal laser irradiation: MRI quantitative analysis of the effects-preliminary report.

Degenerative disc disease is a significant reason for low back pain. Low-level laser irradiation (LLLI) of cartilage results in its reshaping and combines with regenerative reaction. A certain pattern of lumbar disc irradiation induces healing reaction and formation of new cartilage.

How I do it: bilateral lumbar spinal canal microsurgical decompression via unilateral approach.

Background: Bilateral lumbar spinal canal decompression via unilateral approach is a surgical way to treat degenerative spinal canal stenosis.

Method: We report the treatment of degenerative lumbar spinal canal stenosis by removing overgrown ligaments, bone, and other compromising tissue on both sides of the spinal canal, using one side approach, avoiding surgical trauma of the counter side of the spine.

Conclusion: This technique allows to achieve perfect results using common microsurgical instruments and Caspar distractor for one or multilevel surgery.

[Correction of neurological complications after transpedicular stabilization of the spine].

Nowadays transpedicular fixation systems have gained great priority in stabilization of thoracic and lumbar spine. But implantation of the system may cause iatrogenic complications due to extrapedicular insertion (malposition) of screws. Present work is devoted to analysis of neurologic disturbances of screw malposition in the prospective study of 44 consecutive patients.

[Immunohistochemical study of apoptosis in the cells of experimental injured spinal cord].

We studied the temporal and spatial profile of apoptosis following acute spinal cord (SC) injury in rats and influence of chicken yolk transplantation on the programmed cell death. 18 female rats were subjected to complete SC transsection with removal of three millimeters of the SC at the level of the ninth thoracic vertebra. The gap was filled with denaturated chicken yolk in 9 animals.
