Abstract The scope for correction of certain finger deformities, whether congenital or post-traumatic, by osteotomy is defined. The operative procedure may be either a wedge or a rotational osteotomy depending on the type of deformity to be corrected. Operative details of these two procedures are outlined. The value of power driven instruments in carrying out such precision operative procedures is stressed. Examples illustrating both wedge and rotation osteotomies are described and the importance of this latter procedure for enhancing function in the mutilated hand emphasised.
