Which tissue is most important for the early biological repair of a simple long-bone fracture?
Correct answer: D. Periosteum around the fracture
- A. Subcutaneous fat over the limb
- B. Articular cartilage within the joint
- C. Synovial membrane beside the bone
- D. Periosteum around the fracture
Explanation
The periosteum contains osteogenic cells and contributes substantially to external callus formation during fracture healing. Synovial membrane, cartilage, and subcutaneous fat do not provide the main source of early new bone formation.
