introduction arthrogryposis multiplex congenita (amc) with incidence of 1 in 3000 of births is characterized by multiple rigid joint and soft-tissue contractures. case presentation we present a case of amc with severe soft tissue and joints contractures, especially joints of lower limb and elbows, bilateral complete dislocation of hips (cdh) and knees (cdk) (type iii), bilateral elbow joint dis...

larsen syndrome is a skeletal dysplasia (osteochondro-dysplasia) in which multiple dislocations of the large joints are the major feature . nosology in this group of disease, which constitutes 8% of mendelian disorders in man, is primarily based on clinical and radiological features. the underlying genetic defect is 3p21.1-p14.1 in the dominant type

Production of interleukin-10 (IL-10) by C57BL/6 mice following infection with Borrelia burgdorferi has been proposed as a mechanism whereby resistance to the development of experimental Lyme arthritis is maintained. In the current study, we sought to determine the role of IL-10 during infection of arthritis- and carditis-susceptible C3H mice. Infection of C3H IL-10(-/-) mice led to increased jo...

Revolute joints are frequently used in articulated structures. Traditionally, such a joint is formed by assembling two components. As an alternative, revolute joints can be created inside the mold using an in-mold assembly process. This process eliminates the need for post-molding assembly, thus significantly reducing the cycle time and part count. The functional performance of a revolute joint...

In this paper, we study continuous path operation of a 3-RRR planar parallel manipulator whose joints have clearance. During continuous path operation end-effector must go through a predefined path. However, clearance introduces an additional uncontrollable degree of freedom to the manipulator. Therefore it causes error and should not be neglected in a successful path operation. In this paper, ...
