Malunion
A fracture that has healed in an anatomically incorrect position, potentially causing functional limitations or deformity.
Full Definition
Malunion occurs when a fractured bone heals in improper alignment, angulation, rotation, or length. This complication can result in functional deficits, pain, or cosmetic deformity that may require corrective intervention. In rehabilitation documentation, malunion significantly impacts treatment planning as exercises must accommodate the altered biomechanics and may focus on compensatory strategies rather than restoration of normal movement patterns.
Usage
Usage note: Distinct from delayed union (slow healing) and nonunion (failed healing); malunion represents completed but incorrect healing.
