Abstract
Utilizing the techniques of tissue expansion, hair-bearing scalp is created and/or wound closure is effected. Elongated anchor plates are implanted in the scalp at spaced apart locations. Each plate has projecting studs which are extended through incisions in the scalp. A readily attachable and removable skin tensioning means is attachable to the studs and set to the required tension for tissue expansion. Guide means control the force vector applied by the tensioning means to the anchor plates. The tensioning and guide means are attachable for use when the patient is in the privacy of his home. The tensioning means may comprise a pair of straps with a Velcro.RTM. fastener, buckles or the like for the application of requisite tension at a controlled rate.
