Seriously, I can never manage to remember the differences between Monteggia and Galeazzi fractures – especially when it shows up on standardized tests. So, this edition of Fracture Fridays focuses on differentiating the two. Essentially, when one forearm bone breaks and is displaced, angulated and foreshortened something happens to the other one – usually a fracture – but sometimes a dislocation. These are much more common in adults, since pediatric bones have greater plasticity, and often break at the physis. The simple mnemonic I came across states that Monteggia is fracture of ulna. Therefore, Galeazzi is fracture of radius. See, not so great. I’m not a mnemonic guy myself, so I made this handy table.
