Abstract
|
|
|
The authors tried to clarify the effection of the size of femoral stem and degree of porous coating to the stress shielding effect on the primary noncement hip arthroplasty. We obtained the results with the patients of Dept. of Orthopaeics in
INHA
Hospital, INHA medical college, through the period of Feb. 1989 to Feb. 1992. Among the patients who had the hip joint arthoplasty, there were 33 patients with using of AML femoral stem, had fixation with press fit on the immediate post operative
radiologic image, also show the bonny change at the last following radiogram. There were statistically significant meanings of higher rate of bonny resorption by the 3rd degree of stress shielding effect, on the patients with the more than 13.5mm
of
femoral stem size and two-thirds of porous coating femoral stem than the patients who have less than 12.0mm and one-third of porous coating femoral stem(p<0.05).
