Abstract:
Objective:To study the morphology of dorsal medial talar neck osteophyte (DMTNO) and its association with anteromedial ankle impingement syndrome (AAIS) using CT 3D reconstruction images.Methods:The present retrospective study included 23 patients with AAIS due to DMTNO (case group) and 23 patients with DMTNO but without AAIS (control group) who had been admitted from February 2019 to June 2021. Multi-slice CT data (DICOM) of DMTNO in both groups were collected and imported into Arigin 3D Pro 3D reconstruction software to reconstruct and observe the 3D morphology of DMTNO. The dorsal convex distance, medial convex distance and anterior convex distance of DMTNO were measured to find their association with AAIS.Results:In the case group, DMTNO clearly showed a flat polyhedral shape with a large base and a small top; in the control group, DMTNO showed various shapes that were different mainly in an irregular top but similar in a large, long and narrow base. The dorsal convex distance [(8.07±2.30) mm] and medial convex distance [(6.70±2.62) mm] in the case group were significantly larger than those in the control group [(3.59±1.10) mm and (1.98±0.93) mm] ( P<0.05), but there was no significant difference between the 2 groups in the anterior convex distance ( P>0.05). Conclusions:The DMTNO leading to AAIS shows a flat polyhedral shape with a large base and a small top. No correlation is found between the anterior convex and AAIS whereas the dorsal convex and medial convex of DMTNO may be closely associated with AAIS.
