malalignment
Pronunciation: mal-a-LINE-ment
Improper positioning or angulation of bone fragments, joints, or anatomical structures.
Full Definition
Malalignment refers to improper positioning, angulation, or rotation of anatomical structures, commonly used in orthopedic contexts to describe suboptimal bone or joint positioning. This can occur following trauma, during fracture healing, after surgical procedures, or due to developmental abnormalities. Malalignment may involve angular deformities (varus/valgus), rotational abnormalities, or length discrepancies. The degree of acceptable malalignment varies by location and patient factors. Significant malalignment can lead to altered biomechanics, functional impairment, and accelerated joint degeneration, potentially requiring corrective intervention.
Usage
Usage note: Broad term encompassing various types of positional abnormalities; specify the type and degree when documenting.
