動的回内・回外スプリントの作製方法

Fabrication sequence of a dynamic splint for pronation-supination contracture of the forearm

要旨：前腕の回内・回外制限を矯正する目的の改良型Collero-Abrahamスプリントの作製方法，装着方法を紹介した．材料は入手しやすい熱可塑性プラスチックとゴムひもである．本スプリントは，肘関節を90度に保つパーツとフックのついたガタースプリントの2つの大きなパーツから構成され，いつでも修正および調整が可能である．しかし小さなパーツも多く，作製する作業療法士の経験を要する．また装着時は，矯正力が肘関節の内外反方向や手関節以遠の回旋方向に作用しないように注意する必要がある．

　The concept of splinting with low-load prolonged stress for the contracture of soft tissues is beneficial. To correct both pronation and supination stiffness of both radio-ulnar joints, we provide a custom-made modified Collero-Abraham type splint. The splint, made by occupational therapists, can be easily adjusted to the patient's forearm to improve the range of motion. The materials are available thermoplastic and rubber band. It consists of two major parts : one is to keep the elbow joint 90 degrees with 4 rubber bands, and the other is a gutter splint with 4 hooks. The force should affect correcting pronation or supination of the forearm but should not affect inversion/eversion of the elbow joint and not the rotation of the distal wrist joint.
