Abstract

Purpose

Ankle impingement is generally characterised by limited range of motion and pain due to pathological contact between structures. Anterior ankle impingement is usually diagnosed by clinical examination and radiographic evidence of tibiotalar osteophytes. In addition to osteophytes, radiographs may show a correlation between the tibia and talus, which may further aid in the diagnosis of anterior ankle impingement. The purpose of this study is to investigate the relationship between the tibia and talus in anterior ankle impingement.

Methods

In this retrospective cohort study, the tibial coverage of 22 patients with anterior ankle impingement was compared with that of 67 healthy subjects.

Results

The percentage of tibial coverage was 0.674 ± 0.043 in the anterior ankle impingement group and 0.580 ± 0.032 in the control group. The difference between groups was statistically significant (P < 0.05).

Conclusions

In addition to existing criteria, the percentage of tibial coverage may provide valuable information for the diagnosis of anterior ankle impingement.
