[Radiological evaluation of the flexibles pes planus treated with conic endorthesis].

OBJECTIVE

To determine the correction of flexible pes planus by means of the placement of a conic endorthesis in the subtalar joint. Outcomes were based on measures of the Moreau-Costa-Bartani and talar-navicular angles.

MATERIAL AND

METHODS

A series of 22 patients of both genders (7 to 13 years-old), were operated on both feet. The subtalar joint was stabilized by placement of a conic endorthesis. All of them were diagnosed as flexible pes planus, and 44 feet were operated on. All cases had previous conservative treatment without improvement. In these patients the Moreau-Costa-Bartani and talar-navicular angles were measured on lateral and dorsoplantar projections respectively, and compared pre and post-operatively.

RESULTS

Significant correction of the analyzed angles was achieved. We obtained less than 130 p in the "A" angle and less than 150 p in the "B" in the lateral projection, and less than 80 p in the dorsoplantar projection.

CONCLUSION

Normal Moreau-Costa-Bartani and talarnavicular angles were achieved by means of the subtalar placement of a conic endortheses, and normal ranges were obtained in the simple X-rays measures.
