A, Multiple Z-plasties can be used to provide exposure and convert longitudinal skin contractures to zigzag closures. Only one extension typically needs to be made into palm because wide palmar exposure usually allows excision of adjacent diseased tissue. B, When joint or skin contracture is not a major problem, zigzag pattern can be used for exposure, with extended corners as shown to make use of redundant skin. C, Extent of possible undermining of skin is shown in shaded area. D, When only the palm is involved, transverse incisions can be used. E and F, V-Y plasty method of Mukerjea.
