Role in Disease
The most common Achilles tendon injuries are Achilles tendinosis and Achilles tendon rupture. Achilles tendinosis is the soreness or stiffness of the tendon, generally due to overuse. Achilles tendinitis (inflammation of the tendon) was thought to be the cause of most tendon pain, until the late 90s when scientists discovered no evidence of inflammation. Partial and full Achilles tendon ruptures are most likely to occur in sports requiring sudden eccentric stretching, such as sprinting. The area approximately two inches above the calcaneal attachment is most susceptible to these ruptures due to a zone of avascularity. Maffulli et al. suggested that the clinical label of tendinopathy should be given to the combination of tendon pain, swelling and impaired performance. Achilles tendon rupture is a partial or complete break in the tendon; it requires immobilization or surgery. Xanthoma can develop in the Achilles tendon in patients with familial hypercholesterolemia.

Famous quotes containing the words role in, role and/or disease:
“Always and everywhere children take an active role in the construction and acquisition of learning and understanding. To learn is a satisfying experience, but also, as the psychologist Nelson Goodman tells us, to understand is to experience desire, drama, and conquest.”
—Carolyn Edwards (20th century)
“Friends serve central functions for children that parents do not, and they play a critical role in shaping children’s social skills and their sense of identity. . . . The difference between a child with close friendships and a child who wants to make friends but is unable to can be the difference between a child who is happy and a child who is distressed in one large area of life.”
—Zick Rubin (20th century)
“In a country where misery and want were the foundation of the social structure, famine was periodic, death from starvation common, disease pervasive, thievery normal, and graft and corruption taken for granted, the elimination of these conditions in Communist China is so striking that negative aspects of the new rule fade in relative importance.”
—Barbara Tuchman (1912–1989)
