A 27-year-old male boxer presented with pain in the dorsum of right wrist and difficulty getting a firm grip on his hand for 2-month duration. On examination, he had swelling over dorsal aspect wrist. Physical examination revealed bony hard mass at junction third metacarpal capitate bones. The persisted despite conservative treatment patient was referred to our hospital further evaluation. Radi...

INTRODUCTION Giant cell tumors (GCT) of bone are not uncommon. The most common location for this tumour is distal femur, followed by proximal tibia and distal radius (the third most common location). GCT of small bone is a rare presentation. Occurrences in the hand, however, particularly in the carpal bones are rare. We report an unusual case of GCT of Capitate in a 20 year female patient. CA...

Kienbock's disease, or osteonecrosis of the lunate, can lead to chronic, debilitating wrist pain. Etiologic factors include vascular and skeletal variations combined with trauma or repetitive loading. In stage I Kienbock's disease, plain radiographs appear normal, and bone scintigraphy or magnetic resonance imaging is required for diagnosis. Initial treatment is nonoperative. In stage II, scler...

Although based on their long-term clinical evolution there appeared to be no doubt that fractures of the scaphoid modify the mechanical behavior of the carpus, the mechanisms of these modifications have not yet been investigated. This study based on finite element analysis provides insight into the sequence behind the onset of arthritis of the wrist, highlighting the existence of pressure peaks...

Multiple operations have been proposed to slow the progression of osteonecrosis and secondary carpal damage in Kienböck's disease. To assess the biomechanical changes after capitate shorting, we inserted pressure-testing devices into the carpal and radiocarpal joints in an anatomical study. Pressure sensors were placed into eight thawed non-fixated human cadaver arms to measure the forces trans...

A 30-year old male right handed professional tennis player complained about reduced athletic performance, chronic pain and restricted extension of his right wrist. Lateral radiograph of the right wrist demonstrated an osteophyte projecting from the dorsal lip of the lunate bone. The presence of an osteophyte on the lateral radiograph of the lunate along with the history, clinical examination, i...

Osteoid osteoma is a benign bone tumor that rarely affects the carpal bones. Because of its nonspecific presentation in the wrist, it remains a diagnostic challenge. We report an unusual case of osteoid osteoma in the capitate where the diagnosis was delayed and the presentation was that of an aggressive natured lesion with considerable functional incapacitation. Diagnosis was made by computed ...

We measured cartilage thickness, contact surface area, volume of the capitate and shape of the capitate during motion in the operated and unaffected wrists of 11 patients with a mean follow-up of 7.3 years after proximal row carpectomy. Radiocapitate cartilage thickness in the operated wrists did not differ significantly from radiolunate cartilage thickness in the unaffected wrists. The radiolu...

This paper presents the wrist joint MR images of the EULAR-OMERACT rheumatoid arthritis MRI reference image atlas. Reference images for scoring synovitis, bone oedema, and bone erosions according to the OMERACT RA MRI scoring (RAMRIS) system are provided. All grades (0-3) of synovitis are illustrated in each of the three wrist joint areas defined in the scoring system--that is, the distal radio...
