ABSTRACT

Objective:

To evaluate the clinical application of an individualized 3D printed drill template to create a fibular channel in the anatomical reconstruction of the lateral ankle ligament for chronic lateral ankle instability.

Methods:

From October 2012 to June 2015, 15 patients with lateral ankle in-stability underwent surgery at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan.They were 4 men and 11 women, with a mean age of 26.3 years (range, from 18 to 42 years).For each of them, anatomical reconstruction of the lateral ankle ligament was performed through a fibular channel which was created with the aid of an individualized 3D printed drill template.The American Orthopaedic Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS) scores were used to assess the patients preoperation and at the last follow-up.

Results:

The 15 patients obtained a mean follow-up of 15.2 months (range, from 12 to 18 months).Their preoperative AOFAS scores (47.1±3.8) were increased to 88.3±4.7 at the last fol-low-up, and their preoperative VAS scores (5.8±1.8) decreased to 1.55±1.35 at the last follow-up, showing significant differences ( P<0.05).There were 11 excellent and 4 good cases by the AOFAS ankle-hindfoot scale.No significant complications were found.

Conclusion:

In the anatomical reconstruction of the lateral ankle ligament for chronic lateral ankle instability, an individualized 3D printed drill template can help create a fibular channel which exactly fits each individual, leading to positive therapeutic effects.
