The tension cord plaster: a method of immobilising the swollen elbow

A method of immobilising the swollen elbow in a child is described. A length of traction cord is used to block extension, whilst a plaster backslab protects the point of the elbow. Constructive dressings in the cubital fossa may be avoided. This minimises the risk of further swelling and allows assessment of circulation in the elbow, forearm and hand without interfering with the integrity of the cast. Should increasing swelling threaten circulation, the traction cord may simply be cut on the ward to allow elbow extension. Use of this plaster is recommended when flexion of the elbow is necessary to maintain reduction of a fracture, such as following reduction of an extension-type supracondylar fracture.
