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.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
