Editing Varus deformity (section)

==Terminology==
The terminology is made confusing by the etymology of these words. 
* The terms ''varus'' and ''valgus'' are both Latin, but confusingly, their Latin meanings conflict with their current usage. In current usage, as noted above, a varus deformity of the knee describes bowed legs, but in the original Latin, ''varus'' meant "knock-kneed."<ref>{{cite web|title=varus. Charlton T.

* Application of these words in adjectival form to other portions of the body by the medical community has resulted in their definitions changing so that they now refer to the angle of the distal segment (i.e. valgus impaction in a Garden I femoral neck fracture).
* It is correct for a knock-kneed deformity to be called both a ''varus'' deformity at the hip (''coxa vara'') and a ''valgus'' deformity at the knee (''genu valgum''); although the common terminology is to simply refer to it as a ''valgus'' knee.

When the terminology refers to a bone rather than a joint, the distal segment of the bone is being described.  Thus, a varus deformity of the tibia (i.e. a mid-shaft tibial fracture with varus deformity) refers to the distal segment in a varus alignment compared to the proximal segment.{{citation needed|date=September 2021}}
