A new approach to the management of wounds of the extremities. Controlled environment treatment and its derivatives.

Controlled Environment Treatment is a new approach to wound management--for the first time it provides the surgeon with the means of controlling and optimizing the wound environment for the duration of the healing period. Equipment is commercially available and the technique is now being applied internationally; the technique has been established for the treatment of limbs--application to the trunk requires further investigation and development. Spin-offs have already occurred, one being the control of certain types of lymphoedema by the patient in their own home; the other concerns the application of plaster of Paris to produce casts having significantly superior physiological characteristics using minimal manipulative skills. The former is known as Pressure Environment Treatment, the latter is known as Controlled Pressure Casting; equipment is commercially available internationally.
