Lunate bone

Ask a question


The lunate is one of the bones of the wrist, located in the first row of the carpus (a term covering all the bones of the wrist). Its role is important in providing mobility to this part of the forearm. The main problem that affects this bone is dislocation, which can be a cause of "Kienböck disease." In this case, an operation is necessary: it enabling either the removal of the bones and their replacement with an implant, or the locking of the joint.
