Dakins solution is a dilute solution of sodium hypochlorite (0.4% to 0.5%) and other stabilizing ingredients, traditionally used as an antiseptic, e.g. to cleanse wounds in order to prevent infection. The preparation was for a time called also Carrel–Dakin solution or Carrel–Dakin fluid. Use
Carrel and Dakin used a variety of apparatuses to infuse the solution continuously over the wounds. In modern typical usage, the solution is applied to the wound once daily for lightly to moderately exudative wounds, and twice daily for heavily exudative wounds or highly contaminated wounds.The healthy skin surrounding the wound should preferably be protected with a moisture barrier ointment (e.g., petroleum jelly) or skin sealant as needed to prevent irritation. History
The solution takes the name from British chemist Henry Drysdale Dakin (1880–1952) who developed it in 1916, during World War I, while he was stationed at a field hospital in Compiègne. He worked there in collaboration with French physician Alexis Carrel, and the particular use they made of the solution is known as the Carrel–Dakin method for wound treatment. Sodium hypochlorite solution had been developed as a bleaching agent around 1820 by the French chemist Antoine Labarraque, as a cheaper substitute for Claude Berthollets potassium hypochlorite solution, produced as Eau de Javel since the late 18th century. Around that time, he also discovered the disinfectant properties of his Eau de Labarraque, which was quickly adopted for that purpose. His work greatly improved medical practice, public health, and the sanitary conditions in hospitals, slaughterhouses, and all industries dealing with animal products.
A varus deformity is an excessive inward angulation (medial angulation, that is, towards the bodys midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. EX: Varus deformity results in a decreased Q angle of the knee joint. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated outward, in relation to the femur, resulting in a knock-kneed appearance. Conversely, a varus deformity at the knee results in a bowlegged  with the distal part of the leg deviated inward, in relation to the femur. However, in relation to the mid-line of the body, the knee joint is deviated towards the mid-line. EX: Valgus deformity results in an increased Q angle of the knee joint. 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."
