Lower extremity amputation in scleroderma.
Scleroderma or Systemic Sclerosis (SSC) is a disorder characterized by fibrosis of the skin and multiple internal organs. The pathological lesion is a triad of small artery intimal proliferation, medial thinning and adventitial scarring. Autoamputation of fingers and toes is often seen, but only a few cases of limb amputation in scleroderma patients have been reported. The Pittsburgh Scleroderma databank includes 1,030 patients with SSC. Among these were seven patients who sustained lower limb amputation. There were four patients with the CREST variant of SSC, two with diffuse scleroderma, and one who had SSC/rheumatoid arthritis/polymyositis overlap who sustained limb amputation. Of the seven, three were male and five had a significant smoking history. Ages ranged from 46 to 71 years. All patients underwent amputation for nonhealing ulcerations. No problems with postoperative wound healing were seen. Pathologic changes typical of SSC in addition to atherosclerotic peripheral vascular disease were described in one case. Three patients were successfully fitted with prostheses and became independent ambulators. Four patients could not be fitted with prostheses. No skin problems were reported related to prosthetic use. Our review demonstrates that SSC patients who undergo amputation can become successful prosthetic users and should be considered for prosthetic prescription.
