[Minimal interventions in the surgery of osteochondrosis of the lumbar spine].

The authors consider that puncture decompression of the intervertebral disc with using the endoscopic technique and laser evaporation is a method allowing to rapidly and effectively help patients with the root syndrome. All the manipulations are made with local anesthesia. The patients started walking on the second day after operation.

[Reconstructive operations on soft tissues in the treatment of bedsores in patients with spinal injuries].

The paper presents the results of plastic operations on 54 trochanterian bedsores in 48 patients with complicated spinal injury. Early positive results were obtained in 100% of cases when various modifications of a skin-subcutaneous flap was applied in 16 patients with 17 bedsores. There were relapses in 4 patients following a year.

[Matrix endoprostheses for replacement of the tendon-ligament system].

A classification of tendinous and ligamentous implants has been proposed on the basis of their baseline and final strength, taking into account the matrix properties of a material. The experiments on the knee joints and Achilles tendons of laboratory animals have revealed the matrix properties of carbon-containing fiber. Biological reconstruction of tendon ligaments occurs in parallel to the degradation of biodestructive carbon-carbonic fiber (BCF) which is absent in the Vitlana (polymer carbon fiber) implants.

[Microsurgical and endoscopic laser diskectomy in osteochondrosis of the lumbar spine].

Experimental studies have revealed that a pulse surgical laser based on alumo-yttrium garnet with neodymium ensures bloodless diskectomy and evaporation of a pulposus nucleus in the volume sufficient for decompression of the intervertebral disk. Biomechanical studies of spinal resistance following puncture endoscopic laser decompression of the intervertebral disk (PELDID) and microsurgical laser diskectomy (MLD) have demonstrated that these surgical interventions fail to disturb the stability of the spinal portion operated on. A total of 75 patients with radicular syndrome were operated on with the proposed procedures: 32 with PELDID and 43 with MLD.

[Joint prosthetics using carbon implants].

A group of "Intost" materials based on carbon were developed by the I. M. Sechenov Moscow Medical Academy jointly with the Research Institute of Graphite.
