[Experience with Implantation of TP of the Coxa in Osteoporosis.].
Based on X-ray pictures, the authors evaluate the state of osteoporosis by means of bone indexes after implantation of a total prosthesis of the hip joint. They correlate the state of osteoporosis found in the patients with the clinical condition. After 5 years following implantation of TP they found a minimal progression of osteoporosis without restriction of the function of TP of the coxa. Up to ten years after implantation the progression of osteoporosis is apparent, while the functional state of the TP is adequate. After 10 years there is further progression of osteoporosis with restricted function of the TP of the coxa. The cause of progression of osteoporosis is most probably the reaction of the bone tissue to the implant, the type of osteoporosis, reduced burdening when the coxa is insufficient, osteoporosis due to inactivity or osteoporosis as a systemic disease - senile osteoporosis. The investigation indicates some answers to the urgent problems in this sphere: service life of the implanted prosthesis, optimal age for implantation, reaction of the bone to the implant, antiosteoporotic regime, possibly pharmacological treatment of osteoporosis. Key words: osteoporosis, total prosthesis, bone indexes.
