Healing of partial flap necrosis in ankle disarticulation amputation by débridement and continued weight-bearing.

Five patients with partial tissue loss of the weight-bearing surface of the heel pad following ankle disarticulation were treated with residual-limb debridement and continued end-weight-bearing using a total-contact cast. The patients, ranging in age from 53 to 76 years, had insulin-requiring diabetes and insensate heel pads and were low-demand, limited-activity, community walkers before amputation surgery. Each underwent amputation surgery as a consequence of peripheral vascular disease. All patients progressed to complete wound healing over 3 to 6 months and were able to return to their previous ambulatory level using a prosthesis. At a minimum 2-year follow-up, no patient experienced further residual-limb complications. Partial loss of the weight-bearing heel pad in ankle disarticulation amputation does not preclude successful return to independent ambulation using a standard ankle disarticulation prosthesis. Weight-bearing ambulation need not be avoided during healing.
