Univalve split plaster cast for postoperative immobilization in foot and ankle surgery.

Casting is an important part of the postoperative treatment in foot and ankle surgery. Applying a split plaster cast allows for swelling while maintaining surgical correction and alignment. Resecting approximately a 1-in. portion of the plaster cast dorsally and anteriorly maintains stable structural support of the cast while relieving the pressure caused by swelling. We describe a technique for applying a plaster below the knee cast, with a univalve dorsal split, to provide support, while allowing for edema and access to anterior postoperative dressings.
