title: Skin surface pressures under short leg casts.
abstract: Electronic sensors were used to measure skin surface pressures beneath plaster and fiberglass short leg casts. Pressures were recorded after casting, univalving, bivalving, and spreading of casts. Fiberglass resulted in significantly higher pressures than plaster. Beneficial effects of bivalving and cast spreading are confirmed by significant pressure drops. Application of casts by different orthopaedic surgeons and technologists showed pressure differences due to operator technique. However, fiberglass pressures again proved to be significantly greater than those caused by plaster. Excessive pressure beneath casts can cause skin ulceration, and results confirm the need for extreme care, especially when using fiberglass. It is suggested that plaster is safer than fiberglass when significant extremity swelling is likely or when a patient's skin is more vulnerable to breakdown.
