[Symbrachydactyly].
Symbrachydactyly is literally defined as a combination of short fingers with syndactyly. Blauth and Gekeler described four types of symbrachydactyly, ranging from simple shortness of middle phalanges to complete absence of digital rays. In type I (short finger) function is quite normal and syndactyly release is usually the only procedure needed. In type II (cleft hand), presence of a thumb and at least one ulnar finger allows pinch function. Surgical treatment, when needed, consists in separation of webbed fingers, resection of nonfunctional digital stumps, or finger translocation. In type III (monodactyly) all long fingers are absent. Pinch function can be created between the thumb and a toe transfer in ulnar location. Bone lengthening is an alternative procedure to create a pincer. Surgery is not always indicated in type IV (peromely) as function can only be restored if active motion is already present at wrist or carpometacarpal levels.
