Abstract

The aim of this case series was to assess clinical outcomes and achievable correction grades following temporary percutaneous medial malleolar screw epiphysiodesis.

A retrospective chart review of 16 consecutive children with ankle valgus (23 ankles) treated with medial malleolar screw epiphysiodesis in one single institution was performed. Tibiotalar angle, fibular station, and the lateral distal tibial angle were measured before screw epiphysiodesis, and before and after hardware removal.

Mean mechanical and anatomical lateral distal tibial angles were significantly improved by epiphysiodesis (75.6° to 85.2° and 75.7° to 85.3°, respectively, p < 0.005). Similarly, mean tibiotalar angle was significantly improved by screw epiphysiodesis when comparing to the last follow-up before screw removal (5.8° to 14.2°, p < 0.005). We observed a slight rebound following screw removal.

Temporary medial malleolar screw epiphysiodesis is an effective method to treat ankle valgus in children.
