Stresses on your new knee joint
The muscles that cross the knee joint act on the knee joint by a system of levers. The dynamic effect of these combined forces is that the resultant loads acting on the knee joint of a moving person are several times higher than the body weight.
In total knee prosthesis, the stresses are concentrated on smaller areas than in normal knees.
Here are some examples of peak loads that occur on the surfaces of a total knee joint prostheses during sport’s activities: (more…)
Thoracolumbar spinal injuries can be subdivided into those involving the thoracic spine from T1 to T10, those involving the thoracolumbar junction from T11 to L2 and those involving the lumbar spine from L3 to L5.
The understanding of pathomechanics and classification will guide the surgeon during assessment and in establishing treatment priorities. (more…)
The lifetime incidence of mechanical back pain of some type or another is approximately 60% in human beings living in a western culture, with or without a sporting interest. While sportsmen can clearly suffer degenerative and mechanical problems unrelated to their sporting endeavours, there is a series of clinical syndromes and pathological processes that are seen specifically, but not exclusively in sportsmen.
Increasingly, in a leisureoriented culture, not only do these back pain problems afflict professional and top-level amateur sportsmen, but there are many recreational sporting injuries in the general population.
It is important to exclude significant underlying pathology in any patient or sportsman with back pain. The list of red flags popularized in the Clinical Standards Advisory Group document is a very useful guide to screening such patients for significant underlying pathology. (more…)
