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.

[Treatment of uncomplicated vertebral compression fractures].

Unlabelled: According to statistical studies in different countries, the annual incidence of spine and spinal cord injuries is 15-50 cases per 1 million people. In Russia, the incidence of this condition is 5% of the total number of all nonpenetrating traumatic injuries (Neurosurgery: Guidelines for Physicians, ed. by Prof.

Laser-induced regeneration of cartilage.

Laser radiation provides a means to control the fields of temperature and thermo mechanical stress, mass transfer, and modification of fine structure of the cartilage matrix. The aim of this outlook paper is to review physical and biological aspects of laser-induced regeneration of cartilage and to discuss the possibilities and prospects of its clinical applications. The problems and the pathways of tissue regeneration, the types and features of cartilage will be introduced first.

[Clinical studies of transpedicular system using TiNi rod with functionally optimal rigidity].

Transpedicular metal systems are very widely applied in surgical treatment of spinal pathology. Recently TiNi constructions were introduced into practice. This material is characterized by shape memory, superior elasticity and cyclic durability.

[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.

Properties and outcomes of spinal rehabilitation units in four countries.

Objective: Compare rehabilitation after spinal cord lesions (SCL) in different countries.

Design: Multicenter comparative study.

Setting: Four spinal rehabilitation units, in Denmark, Russia, Lithuania and Israel.

[The specific features of clinical manifestations and surgical treatment of spastic and pain syndromes after injury to the vertebral column and spinal cord].

The purpose of the investigation was to study the clinical manifestations of spastic syndrome after injury to the vertebral column and spinal cord and to devise its surgical treatment policy. The investigation included 21 patients with significant spasticity or pain syndrome after severe injury to the vertebral column and spinal cord without any potential of motor recovery. All the patients were observed to have severe inferior paraplegia, cacesthesia following the radicular and conduction with total hypo- or anesthesia.

Reinnervation of the neurogenic bladder in the late period of the spinal cord trauma.

Study Design: Intercostal nerve to spinal nerve root anastomosis in chronic spine-injured patients.

Objectives: To analyze the effectiveness of neurogenic bladder reinnervation in spinal cord-injured patients through artificial creation of sprouting (intercostal nerve to spinal nerve root anastomosis).

Setting: Center of Neurosurgery, Moscow, Russia.

[Prognosis of the outcome of the surgical treatment of the acquired lumbar spinal stenosis].

Not clear-cut indications exist until now for surgical interventions in lumbar spinal stenosis. The satisfying surgical results range from 55% to 98%. The purpose of the present case study was to optimize the data related with the neurological status, magnetic-resonance tomography and with defining the factors having an influence on surgical results.

[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.

[Apoptosis during spinal cord trauma: prospects for pharmacological correction].

Spinal trauma is a serious problem of modern medicine. The morphological studies illustrate the presence of two alternative pathways of cell destruction in the injured spinal cord: immediate necrotic damage and delayed apoptotic destruction of cells. The apoptosis continues for about 14 days after trauma, and it involves both neurons and glia on a significant distance from the traumatic zone.

[The surgical treatment of decubitus ulcers in patients with spinal cord trauma].

The paper summarizes experience in surgically treating decubitus in 429 patients with spinal cord injury. Main criteria for decubitus preparation for surgery, indications for various surgical interventions are defined. The outcomes of treatment are analyzed.

[New possibilities in the surgical treatment of lower thoracic and lumbar spinal injuries].

The paper presents new current approaches to surgically treating the lower thoracic and lumbar spinal injuries. By using new procedures for spinal stabilization, the authors propose algorithms for surgical treatment of spinal injuries in relation to the neurological symptomatology and the severity of fracture and its pattern. The study was performed in the clinical setting.

[Changes in the somatosensory evoked potentials of patients with complicated spinal trauma after an omentomyelopexy operation].

The purpose of the study was to record somatosensory evoked potentials (SSEP) to objectify the results omentomyelopexy in late spinal cord injury. SSEP were recorded in 25 patients in leads of three levels of the somatosensory tract (from the popliteal fossa, from the lumbar enlargement of the spinal cord, and from the surface of the skull in the region of projection of leg presentation in cerebral hemispherical cortex) before and after surgery. The study indicated that there were no pre- or postoperative records of cortical evoked potentials.

[The results of omentomyelopexy in the late period of traumatic spinal cord disease].

The results of omental transplantation to the site of spinal cord lesion in 40 patients in late injury are given. Neurological deficit was alleviated in 17.5% of patients.

[The late-period results of surgical treatment for trauma to the cervical spine and spinal cord].

Seven patients with late-stage spinal cord injury (SCI) at the cervical level were operated on 2 to 11 months following the accident. To assess the preoperative status and the results of surgical treatment, the ASIA motor scoring system was utilized. In 6 cases anterior decompression was combined with a strut graft fusion, one patient was managed via posterior approach, i.

[The dynamic changes in the somatosensory evoked potentials in spinal and spinal cord trauma after meningomyeloradiculolysis].

Sport-latent somatosensory evoked potentials (SLSEP) were used to objectivize the time course of clinical changes after surgery for meningomyeloradiculosis in the late period of spinal traumatic injury. New evidence was obtained for the correlation between the changes in SLSEP with displacement from the lower thoracic and lumbar regions of the spine and these in the clinical picture of the disease (both neurological and urological) following spinal injury.

[Microsurgical reinnervation of the bladder in spinal cord lesions].

The article generalizes the results of 23 reconstructive operations on the roots of the spinal cord for reinnervation of the urinary bladder in patients with injury to the spinal cord. It was found that the operation was indicated in injury to the inferior motoneuron attended by the development of areflexia or hyporeflexia of a hypotonic bladder, which was manifested by the absence of voluntary micturition with a large amount of residual urine and absence of the urge to urinate.

[Surgical treatment of bedsores with blind suture and active drainage in spinal cord lesions].

Operations were performed on 32 patients for persistent bedsores of different localization. The operative technique included plastic surgery of the bedsore with prolonged irrigation of the postoperative wound with solutions of antibacterial agents. In 75% of cases the wound healed by first intention, in 85% the bedsores healed within one month.
