摘要
Abstract
Objective:To explore the anatomical features of the posterior distal tibia and to design a bone plate based on three-dimensional reconstruction.Methods:Computed tomography(CT)data of the distal tibia and fibula from 57 healthy adults(30 males,27 females;30 left,27 right;mean age,42.9 years)were retrospectively analyzed.Forty-nine parameters across nine groups were measured,and differences between sexes and sides were assessed by using the t test or Mann-Whitney U test.Results:Twelve parameters showed significant sex differences(e.g.,HPS,∠A0,∠ CAPM35,DOC35,∠B2),and seven parameters exhibited significant side differences(∠A0,∠CAPM25,∠B1,h2-h4).Transverse sections revealed that the posteromedial ridge transitions from a sharp angle distally to a blunt arc proximally,with DOC and∠CAPM describing the blunt segment.Sagittal section analysis showed that,posterior malleolar height(h)displayed a wave-like pattern,peaking in zone 3 and reaching a minimum in zone 5.The posterior malleolar arc parameters(∠P,d,rad)progressively decreased from distal to proximal.Notable individual variations were observed,with a small proportion of posterior malleoli tending to be flatter and showing markedly larger arc radii than in other individuals.Conclusion:The posterior distal tibia demonstrates quantifiable anatomical characteristics that are partly influenced by sex and side.Three-dimensional measurements provide a basis for the individualized design of helical-surface fixation plates and may offer innovative strategies for the surgical management of posterior malleolar fractures.关键词
