The pisiform bone is one of the eight carpal (wrist) bones. It is a small pea-shaped sesamoid bone located where the ulna (one of the bones in the forearm) joins the wrist (on the little finger side). Pain and tenderness on the palmar and ulnar aspects of the wrist in the area of the pisiform bone is fairly common. Chronic pain in the pisiform area (or wrist pain) may be caused by tendonitis of the flexor carpi ulnaris, bony fractures or osteoarthritis of the pisotriquetral joint.
Osteoarthritis of the pisotriquetral joint is most often caused by acute and chronic trauma and instability. The symptoms of osteoarthritis of the pisotriquetral joint are pain over the pisiform, with pressure and grinding of the joint. There may be ulnar nerve symptoms such as numbness and tingling in the little finger and along the outside of the ring finger.
Conservative treatment of pisotriquetral arthritis consists of local injections of steroid into the pisotriquetral joint along with nonsteroidal anti-inflammatory drugs (NSAIDs) and a protective splint. When conservative therapy fails, consideration may be given to pisiform excision (surgery).
May I suggest you make an appointment with your GP or orthopaedic specialist to discuss further diagnostic investigations and management options.
