Peculiarities of Morphological Changes of Head of Femur in Patients with Hip Joint Osteoarthrosis
Journal Title: Біль. Суглоби. Хребет - Year 2014, Vol 1, Issue 14
Abstract
There were performed a morphological study of 63 heads of femur of the patients with coxarthrosis of dysplastic and idiopathic etiology, stage IV on Kellgren — Lawrence. The type and severity of pathomorphological changes of the femoral head were found to depend on the pathological process etiology and the progress of coxarthrosis clinical course. Deterioration of coxarthrosis is associated with statistically significant increase in occurrence of cystoid remodeling of bone tissue of the femoral head and reduction of degree of bone and cartilage growths in comparison with the heads in the patients with moderate and mild course of the pathological process. Dysplastic coxarthrosis is characterized by intensive osteochondral overgrowth, loss of more than 50 % of the articular cartilage of the femoral head and diffuse subchondral bone tissue concretion. Statistically significant differences in pathological changes of femoral heads associated with coxarthrosis between the groups with different rate of progression of dysplastic coxarthrosis were not detected. The determined features of pathomorphological changes in the femoral head in coxarthrosis will contribute to the clarification of the etiology and prediction of clinical course of the hip joint osteoarthritis.
