We report a case of acute carpal tunnel syndrome caused by periarticular calcification (hydroxyapatite deposition disease) around the wrist joint in a 64-year-old woman. She had acute severe pain, exacerbated by wrist movements and extension of the fingers. Her full blood count, urea, electrolytes, uric acid, calcium, phosphate, alkaline phosphatase, and thyroid function levels were all within ...

Two of the many conditions commonly called " rheumatism" are actual joint diseases?(I) osteo-arthritis, a nuisance but not a calamity, and (2) rheumatoid arthritis, the most crippling of all. In two others there is no joint disease: (3) primary fibrositis, a periarticular or intramuscular condition producing aching and stiffness, and (4) " psychogenic rheumatism "?a psychoneurosis affecting the...

Introduction Intraarticular injections are commonly used in children with JIA to induce prompt relief of symptoms of active synovitis, and obtain disease remission as sole therapy or in combination with systemic treatment. In the recent years, the wider use of musculoskeletal ultrasound allowed to detect more precisely the exact site of inflammation and showed to be a safe guide for injection p...

Ultrasound-guided aspiration of symptomatic ganglion cysts about peripheral joints is a valuable and routinely performed therapeutic modality. Intratendinous and peritendinous ganglia involving the popliteus tendon are rare, with only 3 cases previously reported. These ganglion cysts are usually small and can easily be mistaken for normal anatomy on magnetic resonance imaging (ie, small periart...

The metabolic arthropathies are characterized by the deposition of abnormal substances in or around joints. Certain features of some of these arthropathies and their significance have only recently been recognized and others have been insufficiently emphasized. An important group of conditions are the arthropathies related to renal failure and its treatment, namely, aluminum toxicity, periartic...

Osteoarthritis is the most common joint disorder and a major cause of disability with a major socio-economic impact. In these circumstances is very important to understand its pathogenesis. Although previous research focused primarily on changes in the articular cartilage, more recent studies have highlighted the importance of the subchondral bone, synovium, menisci, ligaments, periarticular mu...

The hybrid fixators, or the fixators that use the thin wire fixation in the periarticular fragment combined with the half-pin fixation in the diaphysis, have made the multiplanar external fixation easier to use and thus growing in popularity. However, the configuration of the ideal hybrid has not been elucidated yet. The purpose of this study was to determine the stiffness characteristics affec...
