Implant Mechanics 101: Load Sharing vs. Load Bearing — Why Constructs Fail


Listen Later

In this episode, we break down one of the most misunderstood principles in fracture repair: what role your implant is actually playing.

Is it carrying all the load? Or sharing it with the bone?
 Because if you mismatch your construct to the fracture — it’s not if it will fail. It’s when.

🔍 You’ll learn:

  • The difference between load sharing and load bearing
  • What happens when implants are too stiff or too weak
  • When to use bridging vs. compression
  • Why implant selection = healing environment
  • Common board traps, like over-stiff constructs and stress shielding

Includes a board-style question + flashcard recap. Built for residents.
