The influence of post-amputation pain syndrome and intraosseous main vessels on the formation of limb bone stump

Until now, remains quit high a percentage of unsatisfactory results amputations. At the same time, special place is occupiedby healing bone remnant — main supporting element stump. Objective. To study influence post-amputationpain syndrome and intraosseous vessels on nature reparative processes in Methods. Three series 15 experimentswere conducted 45 rabbits with amputation femur middle third muscle plastic surgery. In 1st and2nd series, d uring mputation, p erineural c atheter w as b rought to stumps sciatic nerve. With its help, animals were subjectedto following daily for 20 days: mechanical irritation nerve, minutes; 2nd injection 0.3 ml 1 %lidocaine twice day into surrounding area Animals 3rd control. 1, 3, 6 months. histologicalexamination was performed pouring carcass (gelatin mixture) vessels. The results. there sharpviolation process: change shape loosening cortical diaphyseal plate, fractures deformationof stump, significant expansion feeding artery branches perforation endosteal regenerate, absenceof formation closing violation microcirculation. mostly kept shapeand structure characteristic diaphysis normalization macro- stumpformation better than 1st, but worse 2nd. Conclusions. If pain subsides after amputation, bonestump formed an organotypic diaphysis, state marrowtissues blood circulation. rapid complete plate contributes reduction branchesof prevents functional depressurization marrow cavity. presence post-amputation painsyndrome, are violations process inferior penetrationby without
