PROBLEM TO BE SOLVED: To provide a splint for an ankle capable of recovering a sprain and a subluxation of the ankle at a relatively early stage.SOLUTION: A splint 1 for an ankle includes a lower leg support part 2 having a roughly U-shaped cross section for supporting a lower leg part to the vicinity of the ankle, and a sole support part 3 extending forward from the lower end of the lower leg support part 2 and supporting the sole. The angle θ formed by the lower leg support part 2 and the sole support part 3 is 95-105 degrees. It is preferable to provide an aperture 10 for allowing a heel to escape between the lower leg support part 2 and the sole support part 3.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】足首の捻挫や亜脱臼を比較的早期に回復させることができる足首用シーネを提供する。【解決手段】下腿部から足首近傍までをサポートする断面略U字状の下腿サポート部2と、この下腿サポート部2の下端から前方に向かって延びて足底を支える足底支持部3と、からなり、前記下腿サポート部2と前記足底支持部3のなす角度θが95~105度である、足首用シーネ1とした。このとき、下腿サポート部2と足底支持部3の間に、踵を逃がすための開孔10を設けることが好ましい【選択図】図1
