Hook Splint™ Relative Motion Orthosis

A sleek, low-profile Relative Motion Orthosis. Use for finger flexion or extension.

• A waterproof metallic band with a smooth UV-coated silicone finish.
• Locking tab on each end utilizes a novel approach to custom splinting by transforming a ready-to-use, flexible band into a rigid orthosis.
• Sized and fitted directly on the hand into a Relative Motion Flexion or Extension Orthosis for the index, middle, ring, or small finger, depending on the objective. See Border Digit video for tips on how to apply to the small and index finger.
• Hook Splint RMO can be applied to either three or four fingers.
• The open loop design once it is fastened allows for alternation between flexion and extension for a finger that needs both directions.
• Available in size S/M, L and XL, see Sizing Chart.
• The size Small/Medium is made with a softer/more conformable metal; Size Large and XL are made with a thicker, more rigid metal.
