Abstract Purpose of Review To describe the (1) indications,(2) preoperative precautions,
and (3) stepwise technical details of modern femoral stem cemented fixation. Recent …

In this era of subspecialty care in orthopedics, iterations of implant design can occur in a silo
which then precludes gaining knowledge from failures of implant design that may have …

Progressive retroversion of a cemented stem is predictive of early loosening and failure. We
assessed the relationship between direct post-operative stem anteversion, measured with …

Total hip arthroplasty (THA) enjoys excellent rates of success in older patients, but younger
patients are still at risk of aseptic loosening and bone resorption from stress shielding. One …

In joint replacement, stability of the implant is provided by a combination of the techniques
adopted to fix the implant to the surrounding bone and the geometric features of the implant …

There have been significant improvements in surgical techniques and implant designs of
elbow arthroplasty over the last five decades. These advances have resulted in improved …

Background The cemented femoral stem with a distally straight cylindrical shape was
designed to fill the distal femoral canal to facilitate higher cement pressurization and …

Total elbow arthroplasty (TEA) designs can be either unlinked or linked semi-constrained
with a “sloppy hinge.” Unlinked TEA requires an intact or replaced radial head, good bone …

The torsional stability of a polished, collarless, tapered total replacement hip joint stem has
been investigated. It was believed that such a stem would show increasing torsional stability …

When proximal bone stock is compromised at revision hip arthroplasty, distal fixation is often
relied upon for stability of the femoral component. In such circumstances, torsional forces …
