摘要
目的 :探讨跟骨载距突的解剖特点及其临床意义。方法 :对 10 8侧成人跟骨干燥标本和 2 6侧成人足部标本进行解剖学观察。结合观察测量结果 ,分析 45例跟骨骨折患者的X线片和CT片中的载距突移位情况。结果 :载距突的长、宽、高分别为 (2 3 .6± 3 .0 )mm ,(15 .3± 2 .2 )mm和 (9.5± 1.2 )mm。在 45例跟骨骨折患者中 ,无一发生载距突移位。在跟骨载距突的周围 ,有牢固的肌腱、韧带和关节囊附着 ,故当跟骨骨折时 ,这些结构可限制载距突移位。结论 :载距突周围的解剖特点决定了载距突在跟骨骨折中不会发生移位 ,故临床上可利用稳定的载距突骨块作为跟骨骨折行内固定术时的固定点。
Objective:To investigate the anatomic characteristics and clinical significance of the calcaneal sustentaculum tali(ST).Methods:An anatomic study was carried out on 108 adult dry calcaneal specimens and 26 adult cadaver feet.All anatomic data were analyzed compared with the displacements of the sustentaculum tali in X ray plain films and CT scanning of 45 cases of calcaneal fracture.Results:The length,width and height of the sustentaculum tali was 23.6±3.0 mm,15.3±2.2 mm and 9.5±1.2 mm respectively.No displacement of sustentaculum tali occurred.Conclusion:When calcaneal fracture occurred the sustentaculum tali wouldn't be displaced because of the soft tissue around sustentaculum tali.Therefore,sustentaculum tali would be an immovable prominence for the internal fixation of calcaneal fracfture.
