To study the characteristics of tibia anatomy in Vietnamese adults (absolute length of tibia, hard bone length of tibia, medullary canal diameter of tibia), application in treatment of lower and distal fracture of tibia with locked intramedullary nailing. | Journal of military pharmaco-medicine no8-2018 STUDY OF TIBIA ANATOMY IN VIETNAMESE ADULTS: APPICATION IN TREATMENT OF LOWER AND DISTAL TIBIA FRACTURE BY INTRAMEDULLARY WITH LOCKING NAIL Nguyễn Viet Dung1; Nguyen Tien Binh2; Vu Nhat Dinh3 SUMMARY Objectives: To study the characteristics of tibia anatomy in Vietnamese adults (absolute length of tibia, hard bone length of tibia, medullary canal diameter of tibia), application in treatment of lower and distal fracture of tibia with locked intramedullary nailing. Subjects: 228 tibias of 114 Vietnamese adults (67 males, 47 females), average age: ± years old (from 20 83 years old), average height: ± cm (from 143 - 176 cm) (average height of males: ± cm, from 158 - 176 cm; average height of females: ± cm, from 146 165 cm). The study was conducted at Radiographic Department, Viettiep Hospital, Haiphong. Methods: Taking digital radiography of 2 tibias at straight and inclined posture by radiographic machine TOSHIBA Model KXO-32R, connected to computer which has digitizer software, applied in scanning medical film (EFILM Workstation) and achieving images (DICOM) in order to measure study index. Results: Absolute length of tibia was ± cm (from cm), males: ± cm (from - cm), females: ± cm (from - cm). Hard bone length of tibia was ± cm (from - cm), males: ± cm (from - cm), females: ± ( - cm). The narrowest medullary canal of tibia was 8 - 12 cm from bare tibia cartilage. The narrowest medullary canal diameter of tibia in male group was: anterior - posterior ± cm (from - cm), internal - external ± cm (from - cm). The narrowest medullary canal diameter of tibia in female group was: anterior - posterior ± cm (from - cm), internal - external: ± cm (from - cm). The lower
