The use of free fibular grafts has been well reportedfor the treatment of various conditions. These includereconstruction of bony defects and nonunions, osteo-myelitis, bone loss after resection of tumors, spinal sur-gery fusions, and congenital pseudarthrosis of the tibiaamong many others.4,8,9,16 It is an ideal graft in manycircumstances because a vascular inflow can be obtainedif needed. A fibular graft has excellent strength due tothe cortical bone present, and has the potential for re-modeling with loading.4,10 Several studies have lookedspecifically at the resultant donor site morbidity follow-ing free fibular grafting.1,2,3,7,12,19,23 The resultant morbid-ity at the donor site has occasionally been referred toas insignificant or inconsequential.1,9 However, severalreports have found significant functional changes fol-lowing partial fibulectomy, including decreased rangeof motion and strength at the knee and ankle, gait al-teration, and contracture, stiffness and weakness of thegreat toe.2,7,12,19,22 Several other immediate and long-termcomplications of the free fibular graft donor site havebeen documented as well. Donor-site wound-healingcomplications, osteomyelitis and wound infection, tran-sient peroneal nerve palsy, donor-site pain, edema, he-matoma, ankle valgus deformity, and distal fibular os-teoporosis are among the complications cited in theliterature.2,3,7,8,12,16,19 Only eight previous cases of tibialstress fracture following partial free fibular graft har-vest have been reported.6,8,10,22 Two of the eight cases involved a vascularized fibular graft, whereas the re-maining six did not.
