Popis: Background Fusion of the talonavicular joint has proven challenging in literature. The optimal surgical approach for talonavicular arthrodesis is still uncertain. This study compares the amount of physical joint preparation between dorsal and medial approaches to the talonavicular joint. Methods Twenty fresh frozen cadaver specimens were randomly assigned to receive either a dorsal or medial operative approach to the talonavicular joint. The joint surface was prepared, and the joint was disarticulated. Image analysis, using ImageJ, was performed by two blinded reviewers to assess the joint surface preparation and this was compared by surgical approach. Results The dorsal approach had a higher median percentage of talar and total talonavicular joint surface area prepared (75% vs. 59% (p = .007) and 82% vs. 70% (p = .005)). Irrespective of approach, the talus was significantly more difficult to prepare than the navicular (62% vs 88% (p = .001)). Conclusion The dorsal approach provides superior talonavicular joint preparation. The lateral ¼th of the talar head was the most difficult surface to prepare, and surgeons performing double or triple arthrodesis may prepare the lateral talar head from the lateral approach. Level of evidence Level V.
