Abstract
Plantar fibromatosis is a benign but often problematic foot disorder which, when surgically treated, is difficult to eradicate. The purpose of this investigation was to identify epidemiologic factors associated with disease recurrence and to determine which method of treatment most successfully eliminated recurrence.
A retrospective review of surgical pathology reports and clinical histories from 1979 to 1993 was performed to identify all patients who underwent surgery for plantar fibromatosis at our institution during that time. Thirty-three feet of 30 patients were identified with a minimum 2-year follow-up.
Seventeen feet underwent surgery for primary lesions, and 4 of 10 that had local excision, 1 of 3 that had wide excision, and 2 of 4 that had subtotal fasciectomy (with or without skin grafting) had recurrence.
All 16 feet in patients presenting with recurrent lesions had undergone prior local excision at other institutions. When combined with patients from our institution who underwent a second procedure, 21 feet had surgery for recurrent plantar fibromatosis. Of these, three of four had further recurrence when treated with local or wide excision. In feet with recurrences treated with subtotal fasciectomy, only 4 of 17 had recurrence after the first attempt at such treatment.
Average follow-up for all patients was 7.7 years, and all patients with postoperative recurrences showed evidence of disease within 14 months after surgery (mean, 6.9 months). Factors identified with an increased risk for recurrence were multiple nodules, bilateral lesions, and positive family history. In treating recurrent disease, subtotal fasciectomy was more effective than local or wide excision.
This study identified factors associated with a significant likelihood of postoperative recurrence in treating plantar fibromatosis and found subtotal fasciectomy to provide the most successful treatment in eradicating disease in recurrent cases.
