Question

1. Hereditary: one example of this is might be a congenitally short leg 2. Muscular abnormalities: a person with short hamstrings will lose the normal level of lower back curvature because the muscles are pulling and straightening the lumbar curvature of the spine. 3. Ligamentous laxity: laxity is the increased flexibility of a joint. A low level of laxity restricts resistance to the movement of a joint whereas high laxity may cause instability of a joint. One example of this occurs with gymnasts who start too early in their career and overstretch the ligaments within the spine, a disease referred to as Spondylolisthesis. 4. Ligamentous tightness: the lack of exercise causes ligaments to tighten. Many diseases that bring about pain in movement or the destruction of bone or muscle can cause this condition. List at least three of those diseases below

Explanation / Answer

1. Hereditary disease with congenitally short leg is Developmental dysplasia in which ball of the hip bone slips in and out of the pocket and a common symptom is a short leg.

2. The disease in which a person with short hamstrings will lose the normal level of lower back curvature because the muscles are pulling and straightening the lumbar curvature of the spine is Lordosis.

3. Ligamentous laxity is the increased flexibility of joint. A low level of laxity restricts resistance to the movement of a joint whereas high laxity may cause instability. This disease is Hypermobility and also occurs with gymnasts who start too early in their career and overstretch the ligaments within the spine.

4. Charcot Joint is a type of disease in which there is tightening of ligaments and it brings about pain in movement or the destruction of muscle or bone .
