Abstract:
Objective To evaluate the significance of CT assessment for extraarticular anatomy in treatment of displaced intraarticular calcaneal fractures.Methods(1)Measurement of normal calcaneum 40 pieces of adult calcaneum specimen were measured,items of measurement included height of culmination of posterior facet and tuberosity,width of posterior edge of sustentaculum and tuberosity.(2)CT measurement of calcaneum.Transverse(axial)and coronal CT scanning were obtained from 20 feet with displaced intraarticular calcaneal and 20 normal feet as control.Following items were measured in CT scanning:the height of culmination of posterior facet and tuberosity,the coronal talocalcaneal angle,in coronal scanning,the width of posterior edge of sustentaculum and tuberosity,the axial calcaneocuboid angle,in axial scanning.Results(1)Measurement of height of calcaneum height of culmination of posterior facet and tuberosity of calcaneal specimen were(43.07?2.85)mm and(44.69?3.67)mm respectively,and these two items from CT scanning of normal feet were(42.84?1.66)mm,(43.40? 3.01)nun,and from CT scanning of feet with calcaneal fractures were(34.76?3.24)mm,(40.41? 3.69)mm.There was a statistically significant different between these two items for normal calcaneal specimen and for CT scanning of feet with ealcaneal fractures(P
