Abstract

A method for controlling bleeding from bones, comprising the use of copolymers of oxyethylene and oxypropylene or mixtures thereof to cover the bleeding portions of bones. The copolymers are resorbable by the body, not metabolized, simple to prepare, inexpensive, readily available, and do not interfere with the fusion, osteogenesis, and related tissue healing and repair of the affected bones.
