thumbs. She had a history of "double-jointed" thumb, and had pain, tenderness, and abnormal laxity of her first carpometacarpal joints. The other joints were clinically normal, and there was no evidence of generalised hypermobility. Radiography showed chondrocalcinosis and osteoarthritis of the carpometacarpal joints, and aspiration confirmed the presence of pyrophosphate crystals. Metabolic sc...

In this study we report the results of thumb carpometacarpal (CMC) joint replacements in the Norwegian population over a 17-year period. In total, 479 primary replacements performed from 1994 to 2011 were identified in the Norwegian Arthroplasty Register. Implant survival and risk of revision were analyzed using Cox regression analyses. Four different implant designs were compared and time tren...

  Dislocation of the first carpometacarpal (CMC) is a rare occurrence. Treatment of this dislocation varies from closed reduction and casting to ligament repair. Neglected dislocation or incomplete reduction of the 1st CMC cause chronic instability and painful arthritis, muscle imbalance and decreased grip force. In our study 6 patients is evaluated that were visited in less than 24 hours from ...

PURPOSE Among other etiologic factors involved in first carpometacarpal (CMC) osteoarthritis (OA), occupational factors have been postulated as influencing the occurrence of this condition. Very few epidemiologic studies, however, have evaluated this topic. Determining the occupational risk factors is important in proposing preventive measures at the workplace. This case-control study was under...

BACKGROUND The development of osteoarthritis (OA) in the hand results in increased joint stiffness, which in turn affects the grip strength. The goal of the present study is to theoretically analyze the muscle forces in a thumb in response to the increased joint stiffness. METHODS The thumb was modeled as a linkage system consisting of a trapezium, a metacarpal bone, a proximal and a distal p...

STUDY DESIGN Retrospective cohort. INTRODUCTION Conservative intervention of carpometacarpal joint (CMC) thumb pain, caused by osteoarthritis and ligament laxity, is frequently seen in hand therapy. Traditional intervention for pain and disability reduction includes orthoses, exercises, and joint protection education. The literature on conservative management is unclear which design or progra...

RATIONALE Isolated metastasis to the hand bones is very rare. Only seven cases of metastasis to the trapezium have been reported. To the best of our knowledge, this is the first report of a single metastasis to the trapezium from a gastric adenocarcinoma. PATIENT CONCERNS A 62-year-old man presented with pain and massive swelling in the right carpometacarpal joint of the thumb. DIAGNOSES Th...
