HISTOPATHOLOGY OF TENDONS, TENDON-OSSEOUS JUNCTION AND CLINICAL-MORPHOLOGICAL RELATIONSHIPS IN PATIENTS WITH PARTIAL SHOULDER ROTATOR CUFF RUPTURES

Abstract

The article provides information on a study carried out on the basis of materials from patients with shoulder rotator cuff to study the relationship between the frequency of forms of varying severity and clinical and morphometric indicators of this pathology. The gender and age characteristics of patients, clinical and morphological lesion indicators, the degree of mobility of the base, the degree of tendon rupture according to Snyder were studied. Clinical-pathomorphological characteristics were found for supraspinatus muscle tendons that was car70 ried out on biopsy-resectioned material from patients in whom reconstructive operations on rotator cuff tissues were performed, the presence of various pathological changes which display dystrophic, mechanicallydestructive, ischemic and reparative processes in tendons. Between some clinical indices, on the one hand, and morphometric indices of supraspinatus muscle tendon pathological changes – on the other hand, a number of dependences of different force, sign and degree of significance were found. Among clinical indices the highest values of association coefficient were found out by "age of the patient", "a trauma of joint tissues", "remoteness of symptomatology", "functional condition of joint". Among morphometric indices high values of association coefficient show indices "tendon tissue fibrillation", "tendon fascicles desorganization", "angiofibrous tissue proliferation", "tendonecroses".
