[Vascular and microscopic changes in hip joint tissues in Perthes' disease].
Electron-microscopic and angiographic studies of hip joints (healthy and sick) were performed. Bone-cartilaginous tissue and tissue of a joint capsula from 14 patients (7 to 14 years old) obtained during the operation were studied; angiography was performed in 6 patients during their life. Degenerative processes with a predominance of a hydropic dystrophy develop in the joint cartilage of the femur head. Collagen structures undergo mucoid swelling and dysproteinosis. Edema of the joint capsula, mainly its deep layers, is characteristic for this disease. Pathomorphological changes develop against the background of a vascular deficiency.
