Plaster-of-Paris backslabs are presently used after closed or operative reduction of fractures as they are thought to accommodate any swelling which may occur. This study was designed to examine the ability of different types of cast to expand with increasing internal pressure. The results of the study show clearly that a split and spread cast is the only safe cast to use after fracture as it allows for swelling. Backslabs are no better than a complete plaster at accommodating increased internal pressure. It is therefore recommended that backslabs are no longer used to maintain reductions when swelling is anticipated.
目前，巴黎石膏后托板在骨折闭合复位或手术复位后使用，因为人们认为它能适应可能出现的任何肿胀。本研究旨在检验不同类型的石膏在内部压力增加时的扩张能力。研究结果清楚地表明，分块撑开式石膏是骨折后唯一安全的石膏类型，因为它能适应肿胀。在适应增加的内部压力方面，后托板并不比完整的石膏更好。因此，建议在预期会出现肿胀时，不再使用后托板来维持复位。
