fracture gap
The space between bone fragments at a fracture site, which may indicate loss of bone length or poor reduction.
Full Definition
A fracture gap is the measurable distance between opposing bone fragments at a fracture site, representing either initial bone loss from high-energy trauma or inadequate reduction during treatment. Fracture gaps can occur in both acute injuries and during the healing process if reduction is lost. The presence and size of fracture gaps significantly influence healing potential, biomechanical stability, and treatment decisions. Large gaps may require bone grafting, alternative fixation strategies, or acceptance of shortening. Assessment of fracture gaps is crucial for monitoring reduction quality and healing progression.
Usage
Usage note: Use to describe measurable separation between fragments, not general displacement.
