Constriction Band Syndrome

Abstract

Constriction band syndrome (CBS) has various phases of symptoms from a simple constriction of the finger to major amputations, such as that of the forearm. Usually, multiple different phases can be seen in one case, and two conditions are never the same. So. we use a combination of procedures for each symptom, including web-plasty, bone lengthening using external fixator, stump plasty, and even occasional microsurgical manipulation. When treating CBS, we must consider which of the two conditions should be prioritized for treatment. One such condition, although rare, is progressive ischemic change arising due to constriction, which must be released immediately, and another is acro- syndactyly. From the viewpoint of facilitating infantile devel-opment through hand-manipulation, acrosyndactyly must be treated carefully, as soon as possible. Careful management of the cases with sinus tracts is also essential because of the high ratio of infection. For such cases, we usually use the two-stage procedure, consisting of the release of the sinus tracts and late web-plasty.
