Which of the following best describes the 'biological osteosynthesis' principle in fracture fixation?
- A Maintaining fracture alignment while preserving periosteal blood supply, allowing indirect (callus) healing ✓
- B Achieving absolute rigidity to promote primary (direct) bone healing without callus
- C Using bioabsorbable screws that are replaced by bone over time
- D Applying autologous bone graft to stimulate osteogenesis at the fracture site
Correct answer: A. Maintaining fracture alignment while preserving periosteal blood supply, allowing indirect (callus) healing
Explanation
Biological osteosynthesis (minimally invasive plate osteosynthesis philosophy) prioritizes preservation of the periosteal blood supply and fracture hematoma by avoiding direct fracture site exposure, accepting relative stability that leads to secondary bone healing via callus formation. In contrast, absolute rigidity (compression plating) achieves primary bone healing with no callus. Bioabsorbable implants and bone grafting are separate concepts.
