A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries...

The sounds produced by joints are a common source of questioning for doctors and their patients. Two major types are identified : cracks and crepitus. Few investigations have been carried out on these manifestations, while they potentially have clinical implications, especially for patellar crepitus in patellofemoral osteoarthrosis, and may generate anxiety. Knuckle cracking appears to be caused by the sudden and temporary occurrence of an intra-articular gaseous cavity, called tribonucleation. Other researches on these sounds are focused on the knees and their links with osteoarthritis, as well as on the spine...

Cytomegalovirus (CMV) has been described as a contributor to immunosenescence, thus exacerbating age-related diseases. In persons with latent CMV infection, the CD8(+) T cell compartment is irreversibly changed, leading to the accumulation of highly differentiated virus-specific CD8(+) T cells in the peripheral blood. The bone marrow (BM) has been shown to play a major role in the long-term survival of antigen-experienced T cells. Effector CD8(+) T cells are preferentially maintained by the cytokine IL-15, the expression of which increases in old age...

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the prevalent musculoskeletal conditions in young adults and is a leading cause of hip osteoarthrosis in this age group. The optimum age for surgical intervention when needed is not well established in the literature and the lack of management guidelines and standard practice of DDH leads to different practices worldwide. This study aims to investigate the current practice of paediatric orthopaedic surgeons in diagnosing and treating DDH worldwide and identify points of agreement and disagreement...

The potential of quantitative ultrasound (QUS) to assess the regular cellular spacing in the superficial cartilage zones was investigated experimentally and numerically. Nine osteochondral samples, extracted from two human cadaver knee joints, were measured using a 50-MHz ultrasound scanning device and evaluated using Mankin score. Simulated backscattered power spectra from models with an idealized cell alignment exhibited a pronounced frequency peak. From the peak, cell spacing in the range between 15 and 40 μm between cell layers was detected with an average error of 0...

REVIEW
Ralph Gaulke, Christian Krettek
Because of the complex fracture morphology and vulnerable soft tissue coverage, fractures of the tibial pilon are difficult to treat. Complications are more common than in bi- or trimalleolar fractures. The surgeon has to know about the special risks of these injuries to avoid complications. Early complications are soft tissue necrosis, persisting fragment dislocations after surgery, loss of reposition and deep wound infection. The surgeon has to be aware of early signs of compartment-syndrome and chronic regional pain syndrome (CRPS)...

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and synovial hyperplasia, which usually affects multiple joints. The temporomandibular joint (TMJ) becomes susceptible to the development of changes resulting from RA. The aim of this study was to evaluate the presence of TMD and degenerative bone changes in TMJ in patients diagnosed with RA (rheumatoid arthritis). The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/ TMD) questionnaire was used for clinical evaluation of the TMJ and for TMD classification of 49 patients of both sexes and all ages...

Glycosaminoglycans are carbohydrate-based compounds widely employed as nutraceuticals or prescribed drugs. Oral formulations of chondroitin sulfate combined with glucosamine sulfate have been increasingly used to treat the symptoms of osteoarthritis and osteoarthrosis. The chondroitin sulfate of these combinations can be obtained from shark or bovine cartilages and hence presents differences regarding the proportions of 4- and 6-sulfated N-acetyl β-d-galactosamine units. Herein, we proposed a systematic protocol to assess pharmaceutical batches of this combination drug...
