Tibiotalocalcaneal arthrodesis by using proximal humeral locking plate

Abstract

Objectives: The aim of this study was to evaluate the short-term clinical and radiological results of tibiotalocalcaneal arthrodesis (TTCA) with proximal humeral locking plate. Material and methods: Eight patients (7 female, 1 male; average age 53 years (range: 24–67)) who underwent TTCA with proximal humeral locking plate between 2009 and 2011, were retrospectively evaluated with AOFAS hindfoot scale and Maryland foot score system. The mean follow up was 32.6 months (range: 23–54). Results: Complete fusion was achieved in 7 patients. Soft tissue infection was observed in 2 patients and reflex sympathetic dystrophy in 3 patients. All patients recovered with medical treatment. At the final follow-up, mean AOFAS Hindfoot score was 60 (range: 41–81) and Maryland Foot Score was 67.8 (range: 41–85). The satisfactory rates of AOFAS and MFS were found as 12.5% (1/8) and 50% (4/8), respectively. One patient had an incomplete union with 5 degrees of heel varus deformity and 5 degrees of equinus deformity was observed in another. There were no implant failure or deformation of the plate during the follow-up period. Conclusion: Our study suggests that proximal humeral plate may be an alternative for fixation in tibiotalocalcaneal fusion surgery.
