METHOD FOR SETTING LARGE ARTICULATION PROSTHESES Russian patent published in 2003 - IPC

FIELD: medicine. SUBSTANCE: method involves applying low frequency large amplitude ultrasound at various steps of surgical intervention. Contact hemostasis is carried out at the step of tissue cutting, articulation part resection and cotyloid cavity treatment by means of ultrasound. Holes are made in cotyloid cavity after having treated it. Then, the cotyloid cavity is filled with antiseptic or antibiotic preparation. The working end of the instrument is immersed into solution to clean the surface and make cavity hemostasis. After removing liquid, ultrasonic fragmental drying of bone bed surface is carried out for cementing and setting pelvic part of endoprosthesis. Medullary canal is filled with antiseptic or antibiotic preparation before cementing and setting pelvic part of endoprosthesis. The working end of the instrument is immersed into solution to clean the surface and make cavity hemostasis. Ultrasonic treatment amplitude A=50-70 mcm, frequency F= 26-40Hz. EFFECT: reduced risk of traumatic complications; stimulate bone regeneration. 2 cl, 4 dwg
