摘　　要：本实验研究了１０具新鲜尸体距下关节压力的分布。利用压敏片测得６００Ｎ负荷下中立位距下关节的接触压力。结果表明距下关节平均接触压力为１９．３１．３８ｋｇｆ／ｃｍ２，前中关节面和后关节面之间无显著差异（Ｐ＞０．０５）。同时压敏片图形显示大部分负荷由后关节面外侧部分传递。文中还讨论了这些结果的临床意义。The Pressure distribution of the subtalar joints in ten lower legs from fresh adult cadavers werestndied. On neutral Position and under a 600 N load the contact pressures in the subtalar jointswere determined by means of the pressure sensitive film. Results showed that the average contactPressure was 19.3 1.38kgf/cm2 in the joint. There was no significant difference between thepressures of the anterior and medial and the posterior articulation (P>0.05) Meanwhile the imageof the pressure sensitive film showed that a large amount of the load was transmitted by theanterior-lateral site of the posterior articulation. Clinical significance of these data was discussed.
