RESUMO
Guided growth is useful in correcting pediatric angular deformities. Ankle valgus is a coronal plane deformity and is often seen in skeletally immature patients with congenital or acquired lower extremity pathologic features. Temporary hemiepiphysiodesis with a percutaneous transphyseal medial malleolar screw is a surgical treatment capable of correcting the angular deformity and can offer effective correction. In the present case study, a 12-year-old male with dorsal-lateral peritalar subluxation and ankle valgus underwent a reconstructive procedure and temporary hemiepiphysiodesis with a percutaneous medial malleolar screw. After removal of the screw, reduction of his peritalar subluxation was achieved, improving his lateral-distal tibial angle from 81° preoperatively to 89° at the final follow-up examination. The patient returned to his preoperative sporting activities and ambulated comfortably and pain free in sneakers with orthotics. In conclusion, temporary hemiepiphysiodesis with a transphyseal medial malleolar screw is an effective treatment option for ankle valgus in a skeletally immature individual.
