Neurovascular component of the dystrophic process and the development of osteonecrosis in Perthes disease

In 60 patients with reactive synovitis and Perthes disease the thermographic evaluation of neurovascular interconnection was performed. The importance of neurodynamic tissue regulation disturbances of the hip region including microvasculature in pathogenesis of preradiologic lesions transition into the decompensation phase with osteonecrosis development was shown. It was noted that important moment in osteonecrosis development was the achievement of threshold level of neurodynamic vascular regulation disturbances with the involvement of enormous number of neurons from the adjusted segments and loosing of hamper mechanism. Prevention of volume spreading of tissue and neurodystrophic reaction at preradiologic phase is of essential significance for the prevention of process of transition into osteonecrosis phase.
