Conventional uncemented femoral implants provide
dependable long-term fixation in patients with a wide range of functional
requirements. Yet challenges associated with proximal–distal femoral
dimensional mismatch, preservation of bone stock, and minimally
invasive approaches have led to exploration into alternative implant designs.
Short stem designs focusing on a stable metaphyseal fit have emerged
to address these issues in total hip replacement (THR). Uncemented
metaphyseal-engaging short stem implants are stable and are associated
with proximal bone remodeling closer to the metaphysis when compared
with conventional stems and they also have comparable clinical performances.
Short stem metaphyseal-engaging implants can meet the goals of a
successful THR, including tolerating a high level of patient function,
as well as durable fixation. Cite this article:
