Rickets

Rick"ets\, n. pl. [Of uncertain origin; but cf. AS. wrigian to bend, D. wrikken to shake, E. wriggle.] (Med.) A disease which affects children, and which is characterized by a bulky head, crooked spine and limbs, depressed ribs, enlarged and spongy articular epiphyses, tumid abdomen, and short stature, together with clear and often premature mental faculties. The essential cause of the disease appears to be the nondeposition of earthy salts in the osteoid tissues. Children afflicted with this malady stand and walk unsteadily. Called also rachitis.

rickets 
1634, of uncertain origin. Originally a local name for the disease in Dorset and Somerset, England. Some derive it from a Dorset word, rucket "to breathe with difficulty," but the sense connection is difficult. The Mod.L. name for the disease, rachitis, comes from Late Gk. rhachitis "inflammation of the spine," from Gk. rhakhis "spine," but this was chosen by Whistler for resemblance to rickets. Rickety "liable to fall down" (1685) is from rickets via notion of "weak, unhealthy," but has rarely been used in its literal sense.
