3D models reveal best thumb surgery for arthritis pain

This study looks at how thumb arthritis changes joint pressure and how two types of surgery (with or without a metal implant) affect that pressure. Researchers will use CT scans and computer models to simulate loads in the thumb joint. 40 adults aged 50 to 88 with moderate to severe thumb arthritis will be followed for one year after surgery. The goal is to use this biomechanical data to help guide surgical decisions.
