Common Pitfalls in Subtalar Joint Preparation for Arthrodesis via Sinus Tarsi Approach

This cadaveric study assessed factors that could lead to nonunions in subtalar joint arthrodesis. The purpose of this study was to assist surgeons in achieving sufficient joint preparation in hopes to achieve more frequent arthrodesis of the subtalar joint. We evaluated the influence of experience i...

Description
Summary:This cadaveric study assessed factors that could lead to nonunions in subtalar joint arthrodesis. The purpose of this study was to assist surgeons in achieving sufficient joint preparation in hopes to achieve more frequent arthrodesis of the subtalar joint. We evaluated the influence of experience in regard to cartilage preparation of the joint. We also assessed which quadrants of the subtalar joint were more likely to have unprepared cartilage. The subtalar joints in 17 cadaveric limbs were prepared by 17 participants with differing levels of experience. After the cartilage was denuded, the percentage of unprepared cartilage in each subtalar joint was calculated. The medial quadrants were more likely to have unprepared surfaces. There was also a learning curve present with subtalar joint preparation, as seen by the significantly larger percentage of unprepared cartilage in cadavers prepared by first year residents.
