We designed our PIP joint reduction trainer in consultation with emergency medicine faculty. Our customers love how they can use our trainers to test their student's diagnosis skills on multiple fingers and on three different types of PIP dislocations before students step into an exam room. When they first allow a student to attempt a reduction, faculty reduce ligament tension to make it easy to feel the motion required. Then they restore tension so that realistic force is required. Students rave about the confidence they gain by being able to practice joint reductions over and over again with a realistic-feeling hand. It even has the right "pop" when the bones return to normal position.

You probably have a bin full of broken anatomical models, but our trainer has tendons that are easy to replace, meaning that our trainers will help students for years.

Instill Confidence

We gave the PIP Finger Reduction Trainer to 22 health professionals who had each performed  one or two PIP joint reductions.  After they practiced with it for just 15 minutes, they felt significantly more confident in their ability to handle a PIP joint reduction.
