Z-plas·ty

(plas'tē),
Technique to increase soft tissue length along a selected axis; change the direction of a malaligned scar 90 degrees; obliterate or create a web or cleft (as in syndactyly or thumb-web contractures); or alter surface contour. The central limb is located along the malaligned scar or the site of greatest tension; opposing flaps are constructed at each end (or at intervals) along the central limb at angles of 30-90 degrees depending on clinical circumstances. The flaps are elevated and transferred, reorienting the central limb by 90 degrees.
