Mechanical effects of stem cement interface characteristics in total hip replacement.
Stem cement debonding is 1 of the most common forms of fixation failure and is thought to be a prelude to gross loosening of a total hip reconstruction. However, the immediate consequences of debonding remains a matter of controversy. The dynamic effects of stem cement debonding in total hip reconstruction were analyzed using 3-dimensional finite element techniques. Stem cement interface condit...

متن کاملReproduction of fretting wear at the stem-cement interface in total hip replacement.
The stem-cement interface experiences fretting wear in vivo due to low-amplitude oscillatory micromotion under physiological loading, as a consequence it is considered to play an important part in the overall wear of cemented total hip replacement. Despite its potential significance, in-vitro simulation to reproduce fretting wear has seldom been attempted and even then with only limited success...
متن کاملEfficacy of antibiotic-impregnated cement in total hip replacement.
BACKGROUND AND PURPOSE Antibiotic-impregnated cement is used as a spacer or during re-implantation surgery for the treatment of infected total hip arthroplasties. The routine use of antibiotic-impregnated cement during primary or uninfected revision total hip arthroplasty remains controversial. With this meta-analysis of the published literature, we intended to assess efficacy and safety in the...
متن کاملStem torsion in total hip replacement
BACKGROUND AND PURPOSE The clinical results of THR may be improved by correct femoral torsion. We evaluated the stem position by postoperative CT examination in 60 patients. METHODS 60 patients requiring total hip arthroplasty were prospectively enrolled in this study. Minimally invasive THR was performed (anterior approach) in a lateral decubitus position and each patient underwent a postope...
