Thumb CMC Arthritis

Carpometacarpal arthritis, also known as CMC or basilar arthritis, is a common cause of hand pain at the base of the thumb. For those affected by it, many everyday activities such as buttoning a shirt or opening a jar can be difficult and painful.


This interactive book, presented by the Division of Clinical Anatomy and the Robert A. Chase Hand and Upper Limb Center at Stanford University, provides an overview of CMC arthritis and offers information about surgical and non-surgical approaches to treatment.


Written for patients, this book is a supplement to help those with CMC arthritis learn general information about the condition, and not a replacement for medical care from a hand specialist. We also hope this book will be of use to healthcare professionals by aiding patient communication and education.
