Orthopedic Board Exam Prep: Intramedullary Nailing Biomechanics MCQs

Key Takeaway

Unreamed intramedullary nailing's primary biomechanical advantage is preserving the endosteal blood supply, crucial for fracture healing. By avoiding reaming, the technique minimizes damage to vital intraosseous vessels, enhancing the bone's inherent biological capacity for repair, particularly beneficial in comminuted fractures for improved union rates.
