Subtalar arthrodesis

Abstract

Subtalar arthrodesis is an accepted surgical procedure for hindfoot disorders including rheumatoid arthritis, postinfectious arthritis, degenerative joint disease, trauma, neuromuscular disorders, and residual of congenital foot deformities. This procedure has the advantage of joint specific stabilization without restricting motion in the uninvolved transtarsal joints. Several surgical techniques have been described with good long term results. The purpose of this report is to present the indications, describe a surgical technique, and discuss expected results of the procedure currently used. Minimal bone resection to achieve alignment through a small lateral incision, compression fixation, and use of current technology also are discussed. Modifications in technique for special conditions, recognition of common pitfalls, and complications are presented. The results in 45 patients have been encouraging and fulfill the expectations of surgeon and patient.
