Fracture fixation biomechanics
Fracture fixation seeks a mechanical environment compatible with bone repair while respecting vascularity and soft tissue. Optimal stability differs across fracture patterns and healing strategies.

Load sharing
Loads distribute between injured bone and fixation device; construct geometry and fracture contact determine how much load each bears.
Absolute stability
Compression-based strategies can support primary bone healing in selected simple patterns when achieved without excessive biological harm.
Relative stability
Bridging constructs may permit secondary callus healing, especially in suitable multifragmentary patterns.
Biological preservation
Periosteal blood supply, surrounding muscle, infection risk and patient factors interact with the mechanical construct.
