ABSTRACT

Objective:

To investigate the influential factors of internal fixation for closed posterior ankle fractures.

Methods:

The clinical data of 352 patients with closed ankle fractures who received treatment in Yeda Hospital from January 2016 to June 2020 were retrospectively analyzed. Among the 352 patients, 232 patients had posterior ankle fractures. These patients were grouped according to whether they had undergone internal fixation. The factors that affect internal fixation for closed posterior ankle fractures were analyzed by univariate and multivariate analyses.

Results:

232 patients out of 352 patients with closed ankle fractures had closed posterior ankle fractures, accounting for 65.91%. A total of 102 (43.97%) patients with posterior ankle fractures underwent internal fixation. There were significant differences in Bartonicek classification, the proportion of the posterior subluxation of the talus, the proportion of posterior ankle bone area, the proportion of posterior ankle bone area ≥ 25% displayed on X-ray image, the proportion of posterior ankle bone area ≥ 15% displayed on CT scan, the proportion of outward displacement of bone mass (92.31% vs. 41.82%) and the proportion of die-punch bone mass (94.23% vs. 40.00%) between patients receiving and not receiving internal fixation ( χ2 = 3.89, 0.26, 1.51, 0.31, 9.27, 8.67, 1.68, 5.84, 10.33, 12.47, 11.48, 10.69, 1.39, all P < 0.05). Multivariate analysis of a logistic regression model showed that posterior subluxation of the talus and the proportion of posterior ankle bone area ≥ 15% displayed on CT scan were independent influential factors of internal fixation for closed posterior ankle fracture ( OR = 5.47, 9.29, 95% CI1.62-9.75, 3.24-27.01, all P < 0.05).

Conclusion:

In patients with closed ankle fractures, posterior ankle fractures and internal fixation are more common. At the same time, the posterior subluxation of the talus and the proportion of posterior ankle bone area ≥ 15% displayed on CT scan are closely related to receiving internal fixation.
