Free Fibula Donor-Site Morbidity: The Mayo Experience with 100 Consecutive Harvests

ABSTRACT

-A retrospective analysis of 100 consecutive patients undergoing free fibula harvest at the Mayo Clinic is presented. Every patient was analyzed by reviewing postoperative physical examination data. All patients were evaluated and followed in the early postoperative course by the physical medicine and rehabilitation services. Patients were followed from 3 to 60 months, with an average follow up of 17.42 months. In the patient group, 72 flaps were osseous and 28 osteocutaneous.

Thirty-six complications at the donor site were observed in 30 patients. An additional 19 patients required prolonged pharmacologic pain control beyond the first 6 postoperative weeks, with no donor-site complications clinically detectable. Hammertoe was observed in six patients and wound dehiscence in seven patients. Tendon exposure was observed in five patients; partial split-thickness skin graft loss was observed in eight. Numbness of the foot was reported in 10 patients. Fifteen patient had limited maximum ambulatory distance to less than 1000 m. An additional six patients reported difficulty walking stairs.

Attention to details and meticulous wound care are required to further reduce wound-healing complications. Immediate postoperative involvement of the physical medicine and rehabilitation services was beneficial in early patient mobilization and achievement of preoperative ambulation levels. After a short rehabilitation period, the majority of patients were able to engage in all daily activities.
