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.

Isolated pisiform dislocation is rare. We present one such case in a 20-year-old man occurring after a direct injury to the wrist. After an initial delay in diagnosis and unsuccessful closed reduction, he underwent resection of the pisiform. At 12-month follow-up, he had full range of movement of the wrist and no residual pain.

The ulnar tunnel is located at the proximal part of the hand radial to the pisiform bone and to the proximal part of the carpal tunnel. Inside it lie the ulnar nerve and artery. Compression of the ulnar nerve in this tunnel is often reported. Cysts, occupational trauma, fractures and muscle variations are among the main causes (Schjelderup, 1964; Kleinert & Hayes, 1971). Damage to the ulnar nerve and artery during the endoscopic decompression of the carpal tunnel has been reported recently (Agee et al. 1992; Nath et al. 1993; De Smets & Fabry, 1995). The structures within the ulnar tunnel are closely related to the medial part of the flexor retinaculum, in particular the ulnar artery which is located lateral to the ulnar nerve. During a study of this region we found a rare disposition of the contents of this tunnel. We believe that knowledge of this variation is important for the surgical anatomy of this region.

Anatomical variations of the muscles and nerves around the wrist are common. Knowledge of such variations is derived from 2 sources: anatomical dissections and clinically reported cases. We present a case of duplication of the tendon of flexor carpi ulnaris with splitting of the ulnar nerve. The ulnar slip of the tendon was inserted into the pisiform bone and the radial slip into the proximal phalanx of the ring finger. The anatomical literature and the clinically reported cases of variations of the flexor carpi ulnaris are reviewed.

Tendinopathy of the flexor carpi ulnaris tendon is a rare entity. We present a 35-year old tennis player suffering tremendous pain (visual analogue scale (VAS) rating of 9/10) at the flexor carpi ulnaris tendon with adjacent calcification in close proximity to the pisiform bone. Sclerosing therapy using polidocanol under power and laser Doppler guidance was initiated, with immediate decrease of capillary blood flow by 25% with resolution of the neovascularisation in power Doppler. Immediately following sclerosing, the patient's reported pain level on the VAS was reduced from 9/10 to 4/10. Following a short period of rest, eccentric training of the forearm muscle was initiated over 12 weeks with functional complete recovery and complete resolution of wrist pain.
