Excerpt
Uncemented THA is gaining popularity and has overtaken cemented THA worldwide. Uncemented THA is appealing because the majority of cases are performed with ease and without complication. However, periprosthetic fractures can occur around the femur. A periprosthetic fractures is much more likely to occur with stems that have “aggressive” proximal morphology. Watts and colleagues use an institutional database to evaluate the survivorship free of periprosthetic fractures of various stems, and observe that THA performed using the Proxi-Lock (PL) stem had a higher incidence of periprosthetic fractures. …
