【 摘 要 】

Category:HindfootIntroduction/Purpose:Spring ligament tear is often present in advanced stages of the AAFD. Anatomic studies have demonstrated that the superficial deltoid ligament blends with the superomedial spring ligament to provide medial tibiotalar and talonavicular stability. Reconstruction of combined deltoid-spring ligament, or the Tibiocalcaneonvaicular ligament (TCNL) was proposed to augment medial stability in advanced AAFD with large spring ligament tears. A tendon allograft is placed to cross three peritalar (tibiotalar, talonavicular and subtalar) joints to augment medial stability. We aimed to 1) investigate the kinematic effects of TCNL reconstruction in cadaveric flatfoot model with medial ligament insufficiency, and 2) compare TCNL reconstruction with anatomic spring and anatomic deltoid ligament reconstructions (Figure 1). We hypothesized that TCNL reconstruction is effective in restoring peritalar kinematics.Methods:Five fresh-frozen cadaveric foot specimens were employed. Advanced st...
