Disorders of the pisotriquetral joint are well recognised as the cause of pain on the ulnar side of the wrist. The joint is not usually examined during routine arthroscopy because it is assumed to have a separate joint cavity to the radiocarpal joint, although there is often a connection between the two. We explored this connection during arthroscopy and in fresh-frozen cadaver wrists and found that in about half of the cases the pisotriquetral joint could be visualised through standard wrist portals. Four different types of connection were observed between the radiocarpal joint and the pisotriquetral joint. They ranged from a complete membrane separating the two, to no membrane at all, with various other types of connection in between. We recommend that inspection of the pisotriquetral joint should be a part of the protocol for routine arthroscopy of the wrist.

Purpose: Both scaphoid non-union advanced collapse wrist (SNAC) and scapho-lunate advanced collapse wrist (SLAC) at stage II-III are common indications for limited wrist fusions including four-corners fusion (4CF) and three-corners fusion (3CF). The aim of this study was to assess the clinical and radiological outcomes in patients undergoing 3CF vs. 4CF.

A 63-year-old woman had sustained a subcutaneous rupture of the flexor digitorum profundus tendon of the little finger due to osteoarthritis of the pisotriquetral joint. She underwent excision of the pisiform bone and reconstruction of the flexor digitorum profundus tendon of the little finger using an autogenous palmaris longus tendon graft. After surgery, a continuous ulnar nerve block was performed at the forearm under ultrasound and nerve stimulator guidance.

The diagnosis of ulnar-sided wrist symptoms concentrates on distal radioulnar joint and triquetral-hamate joint pathology. I consider this is only looking at the "tip of the iceberg" and ignoring other possible pathologies. In particular, this ignores the role of triquetrohamate and pisotriquetral pathologies.

Fluoroscopy guidance is commonly utilized for injections in the upper extremity, with increased accuracy for injection placement compared to blind injection. Injection of the glenohumeral joint is the most commonly performed upper extremity procedure. However, there are a number of other sites which can be easily injected under fluoroscopy including the acromioclavicular joint, subacromial subdeltoid bursa, biceps tendon sheath, scapulothoracic bursa, elbow, wrist, first CMC joint, and pisotriquetral joint.
