Total hip arthroplasty is one of the most common and successful procedures in orthopedics. With its popularity, numerous prosthetic options and approaches have been employed. The introduction of modular components, femoral components of various shapes, and alternative articulations has made it easier to reconstruct the arthritic hip joint. The intention is to preserve bone stock, while inserting a stable implant through various limited or extensile approaches. Modular components have made the procedure more adaptable to surgical variation, but have introduced the potential complication of metal corrosion at the head-neck interface or neck-body interface with the release of metal debris, resulting in a spectrum of effects such as adverse local tissue reaction, component failure, instability, or osteolysis. Dual mobility bearing hip designs are an alternative to standard articulations with greater stability and may serve as an alternative to large-diameter heads and constrained liners. Uncemented femoral components are designed in various shapes to address the broad spectrum of proximal femoral morphology. Some design features are advantageous, while others have potential consequences.
This issue focuses on several current topics that are relevant to modern hip arthroplasty, including metal corrosion with modular components, dual mobility bearing hip designs, and short uncemented stems.
