Quantitative gait analysis can provide a description of joint kinematics and dynamics, and it is recognized as a clinically useful tool for functional assessment, diagnosis and intervention planning. Clinically interpretable parameters are estimated from quantitative measures (i.e. ground reaction forces, skin marker trajectories, etc.) through biomechanical modelling. In particular, the estima...

The term ganglion was coined by Hippocrates to designate a knot of tissue containing mucinous fluid (Soren, 1966). The aetiology and pathogenesis of these cystic swellings which occur in the region of joints and tendon sheaths is as yet unresolved. On the basis of light microscope studies (Carp and Stout, 1928; De Orsay, Mecray, and Ferguson, 1937; King, 1932; Soren, 1966), ganglia have come to...

Leg length discrepancy (LLD) is a significant factor influencing several pathological conditions. Gait analysis is based on biomechanical gait models calculating joint kinematics; however, no previous study has validated its ability to detect anatomical LLD. The aim of the present study was to compare the validity of the Vicon® Plug-in-Gait-model (PGM) in measuring femur and tibia segmental len...

The extent of synovial cell proliferation in situ and its relationship to the destructive potential of rheumatoid arthritis (RA) is a matter of continuing debate. Notably, the situation has not been elucidated in other inflammatory arthritides [i.e. reactive (ReA) and psoriatic (PsA)], which, although they share some histopathological similarities with RA, develop different patterns of joint in...

Discal cysts--intraspinal cysts communicating with an adjacent intervertebral disc--are an uncommon cause of lumbar radiculopathy. We report a case of discal cyst of the lumbar spine. The cyst contents were bloody and clotted rapidly; no disc materials were seen. Communication between the cyst and the intervertebral disc was detected. Histopathology of the cyst wall revealed fibrous connective ...

Synovial membrane is traditionally considered as a part of the joint capsule. It, however, differs from fibrous part of the capsule in development, structure, function, vascularisation, innervation and involvement in pathological processes. Moreover, in some areas, it even does not contact with the fibrous capsule. Thus, it appears that the synovial membrane should be considered as an independe...

1. A strain of Streptobacillus moniliformis isolated from a case of rat bite fever in man has been found to produce infection of the developing chick embryo following inoculation of the chorio-allantois. 2. The disease in embryos is characterized by invasion of the blood stream and an almost exclusive localization of the infectious process to the synovial lining of the joints. 3. In the early s...

Frost heaving damage of canal lining in cold and dry areas is one the important causes leakage. In this paper, based on bending theory thin plate, a mechanical model under action frost force established solved. Through parametric engineering case analysis, following conclusions are drawn: force, moment, shear internal slope plate show nonuniform distribution, maximum values moment Mx normal str...
