<unk>  is a term for outward angulation of the distal segment of a bone or joint. The opposite condition is called varus, which is a medial deviation of the distal bone. The terms varus and<unk>  always refer to the direction that the distal segment of the joint points. The original latin definitions for varus and<unk>  were the opposite of their current usage. For a discussion of the etymology of these words, see the entry under varus. A mnemonic to remember the two deformities is that<unk>  contains an "L", for Lateral deviation.
