a medical term which means a deficiency but not a total lack of oxygen
Hypoxia (medical) Hypoxia differs from hypoxemia and anoxemia in that hypoxia refers to a state in which oxygen supply is insufficient, whereas hypoxemia and anoxemia refer specifically to states that have low or zero arterial oxygen supply.[3] Hypoxia in which there is complete deprivation of oxygen supply is referred to as anoxia.
Nonunion Nonunion is permanent failure of healing following a broken bone unless intervention (such as surgery) is performed. A fracture with nonunion generally forms a structural resemblance to a fibrous joint, and is therefore often called a "false joint" or pseudoarthrosis (the Greek stem "pseudo-" means false and "arthrosis" means joint). The diagnosis is generally made when there is no healing between two sets of X-ray. This is generally after 6â€“8 months.[1]
