External constant tension expansion of soft tissue for the treatment of ulceration of the foot and ankle

A clinical series of the management of 74 lesions in the foot and ankle region in 67 patients using a constant tension-approximating device is presented. The technical aspects of this methodology are detailed as they have been developed over the past 4 years. The indications, contraindications, and the requirements to obtain a successful result are discussed. The differences, as well as the possible advantages over other mechanical devices used in wound management, are discussed. The incidence and degree of complications are considered to be minimal when compared to both flap procedures and internal expansion technologies.
