Green-Grice extraarticular subtalar arthrodesis: results using a fibular graft.

Thirty-six extraarticular subtalar arthrodeses were reviewed retrospectively to ascertain our long-term results and to determine the better grafting material, tibial corticocancellous bone or a fibular strut graft. The 21 patients had flexible planovalgus deformities due to various etiologies. Overall, satisfactory results (fusion, no pain, and correction of the deformity) were achieved in 83.3% of patients and unsatisfactory results (residual pronation) in 8.3%, and failures (marked pronation or graft resorption) occurred in 8.3%. The fibular strut graft had a better overall success rate, fewer complications, an easier acquisition, and achieved union where the tibial corticocancellous graft failed.
