Preliminary Study on Applied Anatomy and clinical Significance of Ankle Joint

Objective:Through detailed anatomical observation and measure malleolus medialis and malleolus lateralis,the primary bony structure to stabilize ankle joint,in order to provide an anatomical basis for choosing of clinical surgical methods,and setting internal fixations safely and accurately during surgeries to insure the joint stability after surgeries;meanwhile,to offer basic data for measuring Chinese people constitution.Methods:The methods of this paper is to observe and measure the conformations of malleolus medialis,malleolus lateralis and radial related line in selecting 60 pairs of specimens of complete and desiccative adult shin bone,fibula and talus in set,30 pairs of male and 30 pairs of female,paired the right up with the left;and observe and measure the slope angle of malleolus medialis and malleolus lateralis of 60 X-ray anterioposterior and lateral film of standard ankle joints,which are paired the right up with the left.Results:(1)There is no statistical significance(P0.05)when comparing the same gender parameters of right and left side of malleolus medialis with malleolus lateralis.(2) There is statistical significance(P0.05) between male and female parameters on radical lines of malleolus medialis and malleolus lateralis.(3)There is no statistical significance(P0.05) between male and female parameters on malleolus medialis angle and malleolus lateralis angle.Conclusion:(1)There exist gender differences between male and female in primary radial lines of malleolus medialis and malleolus lateralis,however,no differences between slope angles.(2)This study primary raises the concepts and measure methods of malleolus medialis and malleolus lateralis parameters and obtains the authentic data about radial lines.This study provides the anatomical foundation for choosing the inner fixation material for ankle joints fractures,setting inner fixtures accurately and safely during surgeries,and rebuilding the deficiency of malleolus medialis and malleolus lateralis.
