МОРФОЛОГИЧЕСКИЕ ИЗМЕНЕНИЯ В МЫШЕЧНОЙ ТКАНИ ПРИ РАЗЛИЧНОЙ СТЕПЕНИ КОНТРАКТУРЫ
MORPHOLOGICAL CHANGE IN MASCLE TISSUE AFTER CONTACTURE

Summary/Abstract: The article of the treatment of congenital dislocation of a femur by reposition is the re-moving of femoral by step by step for correction of femur position at acetabulum with applica-tion of removing trunks and plaster bandages. However free reposition may be difficult owing to tension of m. adductor longus. Children with a congenital dislocation of femur underwent repo-sition can be in position of removal of hips with muscular tension for a long time, causes mor-phological shifts in a muscular tissue and may be the reason of unsatisfactory treatment results. The purpose of work: the morphological analysis of a muscular tissue at contractures of a various degree. There was analyzed 2 groups of patients with an easy and heavy degree of con-tracture. The morphological analysis of muscles at contracture has shown, that changes are marked not only in muscular fibers, but in endomysium, perimisium, epymisium, and their ex-pressiveness depends on a degree of contracture. Muscular fibers become polymorphic on the thickness. Depending on a degree of contracture the proportional increasing of fibers with de-nuclearized zones was observed, the amount of stratification of fibers with a denuclearized zone of the next fiber was increased. The amount of vessels in sight a cross cut of a muscle has shown decreasing of their number depending on a degree of femoral contracture.
