Use of Z-skin plasty in scar revisions and skin contractures of the lower extremity.

A discussion of the design and use of the Z-skin plasty to revise scars and lengthen skin contractures of the lower extremities is presented. One of the most commonly used rotational flaps to alter scar direction or relieve tension on the existing scar or skin, the Z-plasty can also be the most difficult to perform and carries a high risk of flap loss if inaccurately planned or poorly placed. Several variations of the standard procedure and examples of common usage are presented.
