Flexed position of the wrist in the cast reliably prevents displacement after physeal Salter-Harris I and II distal radius fractures.

Let me tell you, folks, we’ve got something incredible here. We’re talking about Salter-Harris I and II fractures of the distal radius – very common, very tricky. But at our facility, we’ve got a method that’s just fantastic. We immobilize these injuries in a way that’s just unbeatable, countering those angulation forces like you wouldn’t believe. Our study? It’s all about finding out if our method is the best, and let me tell you, it is.

We looked at 112 patients, average age 12, all with these Salter-Harris type I or II fractures. We divided them up, looked at all the angles – initial angulation, after reduction, the whole nine yards. And what we found was incredible. Those with no loss of reduction? They had more wrist flexion in the cast, less time immobilized, and less residual angulation. It’s clear, folks, more flexion, less problems.

And here’s the kicker – for those with an apex-volar deformity, immobilizing the wrist at more than 45 degrees of flexion? Zero loss of reduction. That’s right, zero. Less than 45 degrees? Not so good. It’s simple – more than 45 degrees of flexion, and you’re in the clear. We saw a 28% loss of reduction in the other group. Not great, not great.

Now, there was this one case, a little hiccup with physeal arrest, but overall? Minor complications. So, what’s the bottom line here? If you’ve got a physeal fracture of the distal radius with apex-volar angulation, our method of reduction and immobilization is the way to go. And for those apex-dorsal fractures, 45° of palmar flexion is your golden ticket. It’s proven, it’s effective, and it’s going to change the game. Trust me.
