We present a 64-year-old woman with rheumatoid arthritis who developed increasing pain 3 years after a total wrist arthroplasty. The pain was localized over the ulnar side of the wrist secondary to erosion of the pisiform. Pisiform excision resulted in a resolution of the symptoms. When placing a carpal component, which includes a base plate as part of its design, care should be taken to avoid any overhang of the implant edge into the pisotriquetral joint.

    ABSTRACT: Acute or chronic pain at the pisiform may be due to tendinopathy of the flexor carpi ulnaris tendon (FCU) insertion, mechanical overuse, bony fractures, and osteoarthritis of the pisiform-triquetral joint. Enthesiopathy of the FCU at the pisiform might exhibit abnormalities assessable for sonographic characterization. This study aimed to determine the most relevant sonographic features of tendinopathy of the FCU insertion at the pisiform. We retrospectively analyzed radiological findings of 9 patients admitted for high-frequency sonographic evaluation of a painful pisiform FCU insertion. The FCU insertion was assessed for active enthesiopathy in terms of tendon thickening and hyperemia, peritendinous effusion, peritendinous hyperemia, peritendinous soft tissue thickening, cystic fluid collections, erosive cortical irregularities, and osteoproliferative alterations at the pisiform. Of all patients, 5 had inflammatory rheumatic disorders and the remainder had a painful pisiform FCU insertion related to overuse. While peritendinous effusion, pisiform erosive cortical irregularities, and peritendinous soft tissue thickening at the FCU insertion were exclusively found in rheumatic patients, active enthesiopathy of the FCU tendon, pisiform osteoproliferative alterations, and hyperemia of the peritendinous soft tissue were inconsistent and found in both groups. Cystic fluid collections from the pisiform-triquetral joint were only seen in patients with overuse. In this small case series of patients with pain at the pisiform FCU insertion, we could reveal several typical sonographic features for insertion tendinopathy. Further studies should prove if these sonographic features could impact on the management of patients with pain at the pisiform.

    ABSTRACT: Proximal row carpectomy (PRC) is an established surgical procedure used to treat post-traumatic osteoarthritis of the wrist with sparing of the midcarpal joint and advanced aseptic necrosis such as lunatomalacia. Proximalization of the distal carpal row following PRC may lead to secondary problems such as radiocarpal impingement. At follow-up, two of our patients complained about ulnar-sided wrist pain after proximal row carpectomy. Computed tomography (CT) scans were taken for both patients with an additional magnetic resonance imaging scan for one patient. The CT scan revealed clear osteolysis consistent with a pisiform bone impingement on the ulnar styloid process in both the cases, and also on the hamate in one patient. An impingement syndrome of this nature has not previously been described and should be kept in mind when patients report ulnocarpal symptoms after PRC.
