Arthrodesis of the Ankle with Lateral Plating

Abstract

A modification of internal fixation compression arthrodesis for ankle fusion is described using two 6.5-mm cancellous bone screws and a lateral T plate. Using this technique, 20 consecutive arthrodeses by one surgeon were reviewed. Solid union was attained in 19 of 20 patients (95%). Average follow-up was 18 months (range 6–59 months). Time to obtain solid arthrodeses averaged 18 weeks. In 11 patients who returned for follow-up, clinical grading using the Mazur scale score averaged 70 of 90 points. Diagnoses included posttraumatic degenerative arthritis, failed ankle arthrodesis and rheumatoid arthritis (2 each), failed ankle arthroplasty, and posttuberculous arthritis (1 each). Complications included one malunion and one asymptomatic screw malposition. All patients attaining union were pleased with the procedure.
