Original Article: ⁠⁠ ⁠⁠⁠⁠⁠⁠How Orthopedic Surgeons Fix Bones - Part 1

Summary:

In this episode of the Rules of Thumb Podcast, Dr. Nick Golinvaux delves into the intricacies of orthopedic surgery, specifically focusing on how orthopedic surgeons fix broken bones. He explains the two primary mechanisms of bone healing: primary and secondary healing, with a detailed exploration of primary bone healing. The episode highlights the importance of compression at the fracture site, the use of plates and screws, and the overall healing process. Dr. Golinvaux also discusses alternative techniques for achieving bone compression, providing listeners with a comprehensive understanding of the surgical process involved in bone repair.

Takeaways:

• Fractured bones can heal in different ways depending on the characteristics of the break and how stable they are as they heal.


• Orthopedic surgeons need to know which type of bone healing they want to achieve when designing an implant to fix the fracture.


• Primary bone healing requires compression at the fracture site, which can be achieved with compression plating, lag screws, or headless compression screws.


• The ends of the bones must be within 200 microns of each other for primary healing to occur.


• A single break across the bone is ideal for primary bone healing.


• The 'magic screw' plays a crucial role in compressing the fracture site.


• Most hardware used in surgery becomes irrelevant after the bone heals.


• Alternative techniques for compression include lag screws and headless compression screws.


• Understanding the mechanics of bone healing can enhance patient education and awareness.


• Knowledge of orthopedic tools and techniques can be beneficial for both patients and practitioners.
