Surgical treatment method of children with dysplastic coxarthrosis
The aim of this study was the rationale subdestructivе cryotherapy with the identification of the optimal exposure for the recovery of refrigerant. Histomorphological studies have shown that in 3-second cryotherapy the most active regeneration, provided cartilaginous tissue with lots of blood vessels, chondrocytes and osteocytes, is observed. Other refrigerant exposures present a pronounced development of connective tissue (6-9 seconds) or crioosteonecrosis (12 seconds). The experimental results allow to recommend differentiated regenerative cryotherapy for the treatment of the model of aseptic necrosis of the femoral head in the experiment.
