Summary Introduction
Introduction:
The calcaneal tendon or Achilles tendon rupture is commonly affects the sports people especially in recreational sports. Moreover, the calcaneal tendon rupture is more usual in old age and middle age people. This calcaneal tendon is a strong fibrous tendon, which connects the muscles from the back of the calf to heel bone. Whenever the tendon is overstretched it will lead to complete or partial rupture. Usually this type of rupture will occur when jumping, falling from a height, and stepping into a hole.

- At first, Donnie’s wife accused her once-active 25-year-old husbandof trying to get out of housework by constantly complaining aboutpain and stiffness in his lower back. But over the next 5 months, thepain and stiffness increased and seemed to be spreading up his vertebral column. The family doctor referred Donnie to a rheumatologist,who diagnosed ankylosing spondylitis (AS). AS, a chronic inflammation of joints at points where ligaments, tendons, and joint capsuleinsert into bone, causes fibrosis (the development of scar tissue), ossification, and fusion of joints. Combine your knowledge about bonegrowth, repair, and anatomy from chapters 6 and 7 and joint structureand function from this chapter to identify the category of joints primarily affected by AS, and explain how chronic inflammation ofDonnie’s joints led to their fusion.arrow_forwardDefine Achilles tendonarrow_forwardWhy is tetanic tension so much greater than twitch tension?arrow_forward
