Computer-aided manipulation of photographs for leg lengthening

The use of composite photographs to aid the patient and the consultant to assess the visual effects of different degrees of leg lengthening is now a well-established practice at the Royal Hallamshire Hospital, Sheffield. The original photographic composite technique was both time consuming and intricate. By the use of the Apple Macintosh computer and software such as Digital Darkroom, major advances over the old technique have been achieved resulting in a more accurate representation of what is hoped will be the final operative appearance.
