[Minimal interventions in the surgery of osteochondrosis of the lumbar spine]. / Minimal'nye vmeshatel'stva v khirurgii osteokhondroza poiasnichnogo otdela pozvonochnika.

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.

[Microsurgical and endoscopic laser diskectomy in osteochondrosis of the lumbar spine]. / Mikrokhirurgicheskaia i éndoskopicheskaia lazernaia diskéktomiia pri osteokhondroze poiasnichnogo otdela pozvonochnika.

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. The subsequent studies have shown that 69 (92%) patients returned to previous work at week 7 and 5 (6.7%) at week 9 of postoperation. The major manifestation of radicular syndrome--leg pain--was eliminated in 100% after MLD and in 96.9% after PELDID.

[Matrix endoprostheses for replacement of the tendon-ligament system]. / Matrichnye éndoprotezy dlia zameshcheniia sukhozhil'no-sviazochnogo apparata.

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. The expediency of extra- and intraarticular implantation of the Vitlana and extraarticular one of BCF has been evidenced. The use of the Vitlana implants is found justifiable to replace Achilles tendon defects. Due to the occurrence of complications, it is not advisable to use BCF for intraarticular management of and plastic operations for Achilles tendon defects.
