思春期特発性側弯症の装具療法：エビデンスとガイダンス

思春期特発性側弯症（AIS）は、思春期の子どもの約2〜3%にみられます。成長期で弯曲が十分に大きい子どもでは、装具が、多施設ランダム化試験で手術率を下げると証明された唯一の非手術的治療です。

以下はエビデンスと推奨の要約です。表と出典を備えた全文はベトナム語と英語でご覧いただけます。

ポイント

  • AISの子どもの約10人に4人は、治療しないと弯曲が進行します。
  • 最も危険な時期は思春期の成長のピークで、50°という基準が成人後の見通しを左右します。
  • 装具は、弯曲が20° ± 5°以上で進行リスクのある成長期の子ども（Risser 0〜3）に勧められます（SOSORT 2016）。
  • 夜間装具（CONTRAIS、2024年）：成功率76%、特異的運動58%、身体活動のみ53%。
  • 運動（Schroth/PSSE）の利点は小さく、装具の代わりではなく併用で最も効果的です。

科学的根拠

  • BrAIST：242人、コブ角20〜40°、Risser 0〜2。装具の効果が明らかで早期に中止されました。
  • Cochrane 2015：7件の研究、青少年662人 — 装具は弯曲の進行を防ぎます。
  • 装具内での初期矯正は成功と強く関連します（Eur Spine J、2019年）。
  • 電子モニタリングは平均着用時間を1日3.47時間延ばしました（PLOS ONE、2022年）。
  • クリニックの症例：15歳、コブ角38.65°。昼用・夜用の2つの装具で約14か月後、装具なしで10°、昼用装具内で0.2°、夜用装具内で−2.6°。装具内での矯正が大きいほど結果が良い傾向があります。van den Bogaart（Eur Spine J 2019、26件）は、初期の装具内矯正の不足が治療失敗と関連するという強い根拠を示し、Emans（Spine 1986、295人）、Katz（JBJS 2010：1日12時間超の着用で82%が進行なし、7時間未満では31%）も同様です。これは関連であり、因果の証明ではありません。
How to read: each horizontal bar is a group of children; the longer the bar, the higher the success rate. SUCCESS means that when growth ended the Cobb angle was still below 50° (no surgery). Observation only: 48%. Brace worn 0–6 hours/day: 41%. Brace worn 12.9 hours/day or more: 90–93%. Wear time was measured by heat sensors inside the brace, so it is a real measurement rather than self-report; the link between hours worn and success was statistically significant (P < 0.001). Note that this is an analysis by actual wear time, so children who wore it longer may also differ in other ways. Source: Weinstein et al., NEJM 2013;369:1512–1521 (242 children, Cobb 20°–40°, Risser 0–2).

How to read the films: four standing X-rays of the same patient, shown at the same size for easy comparison. The first tile (orange frame) is before treatment (2 August 2022): the orange lines are the Cobb-angle measurement lines, result 38.65°. The other three tiles (green frames) were taken on 24 October 2023, after about 14 months: out of brace (10°), in the night brace (−2.6°, curved to the opposite side) and in the day brace (0.2°); the bright round and elongated objects are the pads and frame of the brace. The large figure under each film is the Cobb angle. The patient-name line printed on the films has been masked; everything else is kept as on the original films. Image source: dungcuchinhhinh.vn.

実践的なアドバイス

  • 早期のサインに気づく：肩の高さの違い、出っ張った肩甲骨、左右非対称のウエスト、前屈時の肋骨の隆起。
  • 成長期のうちに専門医を受診し、X線撮影を受ける。
  • 装具は個別に製作し、装具内の矯正を確認し、成長に合わせて調整する。
  • 着用時間（1日12.9時間以上）、皮膚、お子さんの気持ちを見守る。経過観察のX線は通常6か月以上あける。
