Vanadium is a minor constituent of titanium-aluminum-vanadium alloys used in hip prostheses, both in the femoral stem
and less frequently in bearing surfaces (acetabular sockets).
In recent publications, the authors state that approximately 75% of periprosthetic fractures around a primary femoral stem
are associated with a loose stem.
Background: Cementless fixation of the femoral stem
has been shown to be durable and predictable in total hip arthroplasty (THA), primarily as a result of recent improvements in prosthesis geometry and porous surface.
The morphometric method to understand the shape and size of the proximal femur regarding femoral stem
design was firstly described in detail by Noble et al.
Uncemented 100-mm tibial and femoral stem
extensions were routinely used for additional fixation.
examined the outcome of the femoral stem
of four generations of an uncemented, proximally porous-coated, chrome-cobalt total hip prosthesis in 141 osteonecrosis patients, who had a mean age of 46 years.
CorinCormet total hip replacement systems, involving the CorinCormet 2000 metal-on-metal acetabular cup and femoral head used in conjunction with a Corin femoral stem
or the Endo-Plus/Smith & Nephew SL Plus Stem.
A retrospective survey performed by the American Association of Hip and Knee Surgeons estimated the prevalence of femoral stem
fractures to be 0.
s (NASDAQ: EXAC) new AlteonMonobloc Revision Femoral Stem
, which is among three new Exactech revision systems making their clinical debut, the company said.
2) The femoral stem
, however, has very good long-term reports both in cemented and cementless forms.
First, femoral stem
can be inserted in the femoral bone.
The inferior margin of the polyethylene cup was worn out by impingement of the femoral stem
, which subsequently broke the locking mechanism.
