periarticular fracture
Pronunciation: per-ee-ar-TIK-yuh-lar
Fracture occurring near but not necessarily involving a joint surface.
Full Definition
A periarticular fracture is a fracture that occurs in the region around a joint, typically within the metaphyseal or metaphyseal-diaphyseal junction areas, but may or may not involve the actual joint surface. These fractures are significant because of their proximity to joints and potential to affect joint function, even when the articular surface remains intact. Examples include supracondylar humeral fractures, intertrochanteric femur fractures, and proximal tibial fractures. Management considerations include preserving joint motion, preventing stiffness, and addressing any associated ligamentous or soft tissue injuries that commonly accompany fractures in these locations.
Usage
Usage note: Do not hyphenate 'periarticular'. Distinguish clearly from 'intra-articular' (involves joint surface) and 'extra-articular' (away from joint).
