[Densitometric evaluation of the proximal femur after cemented hip prosthesis]

Results of DEXA densitometry evaluation of the proximal femur in 12 patients after cemented total hip replacement are demonstrated. Bone mineral density of the femur was measured using the dual energy absorptiometry Lunar DPX. Assessment was performed in the 3rd or 4th postoperative day, after 3rd, 5th and 12th week, after 6 and 9 months following surgery. A decrease in bone density around prosthetic stem ranging from 15% to 30% of the primary level was observed already in the third month after operation. The process continued and the values after 9 months were significantly lower then initial ones.
