Failure of a modular hip implant at the stem-sleeve interface.
In the current era of total hip arthroplasty (THA), orthopedic surgeons have several fixation options at their disposal. The modern monoblock prosthesis, introduced by Dr. Sir John Charnley, has seen many modifications since its inception in the 1970s and continues to be the most commonly used prosthesis style for primary and revision THA. Proximal modular sleeve technology was introduced in 19...
متن کاملTorsional resistance and wear of a modular sleeve-stem hip system.
The torsional resistance and wear debris generation of the modular sleeve and stem S-ROM total hip system was evaluated. The results indicate that slippage of the sleeve-stem interface may occur under physiological loading conditions. Slippage is more likely to occur if the junction is contaminated by blood or tissue, or if the stem is disengaged and reimplanted into the sleeve. Significant ...
متن کاملFailure of Emperion modular femoral stem with implant analysis
Modularity in total hip arthroplasty provides multiple benefits to the surgeon in restoring the appropriate alignment and position to a previously damaged hip joint. The vast majority of modern implants incorporate modularity into their design with some implants having multiple modular interfaces. There is the potential for failure at modular junctions because of fretting and crevice corrosion ...
متن کاملFracture of cementless femoral stems at the mid-stem junction in modular revision hip arthroplasty systems.
BACKGROUND Mechanical failure of femoral stems at the modular junction of revision hip arthroplasty systems has been reported only infrequently. In the current study, the cause of six stem fractures, which occurred in vivo, was analyzed with use of clinical data and failure analysis. METHODS Six patients with a fracture at the mid-stem junction of a modular revision hip implant were identifie...
متن کاملModular hip implant fracture at the stem-sleeve interface.
The use of modular implants in femoral stem design has grown increasingly popular over the last decade because of the theoretical advantage of more flexibility and optimization of femoral anteversion, limb length, and femoral component offset. With the benefit of increased surgical flexibility, however, modularity also carries the theoretical risks of fretting at the modular surfaces, sequelae ...
