Results of subtalar arthroereisis for posterior tibial tendon dysfunction stage IIA1. Based on 35 patients

Background

The aim of the study was to evaluate the clinical and radiological results obtained in the treatment of adult flexible flatfoot secondary to posterior tibial dysfunction with subtalar arthroereisis using a Kalix ^® endorthesis.

Methods

35 patients (37 feet) were studied, having been operated between January 2010 and January 2015 for reducible flatfoot secondary to posterior tibial tendon dysfunction stage IIA1 of Bluman.

Results

The average follow up was 47.52 months with a minimum of 14 months and a maximum of 75 months. The average age was 54.85, with an age range from 40 to 80 years old. In 74% of cases excellent or good results were obtained, according to our evaluation. The most common complication of this procedure was persistent pain in the sinus tarsi. 35% of cases in this group required implant removal for this reason.

Conclusions

We believe that arthroereisis is valid for the treatment of flat foot secondary to posterior tibial tendon dysfunction at this stage, giving a high percentage of good and excellent results.
