Hand Orthosis and Finger Splint Quiz

Wrist and Hand Orthoses

• Dorsal WHO (Wrist-Hand Orthosis): Supports wrist in radial extension to correct ulnar deviation; includes thumb opposition with thumb in abduction and internal rotation.
• Long and Short Opponens Splints: Maintains thumb position and wrist alignment; beneficial for various wrist immobilization needs.
• Bennett Type Metal Hand Orthosis: Offers durable support for finger positioning.

Finger Orthoses

• Static Finger Orthoses:
  • Boutonniere Orthosis: Corrects hyperflexion at the PIP joint applying the 3-point pressure principle.
  • Swan Neck Orthosis: Addresses Swan Neck deformity where the PIP joint hyperextends while the DIP joint flexes.
  • Mallet Finger Orthosis: Supports the distal finger joint when it cannot straighten independently, allowing joint repositioning but not maintenance.

Dynamic Orthoses

• Shoulder Orthosis:
  • Balanced Forearm Orthosis: Assists elbow and shoulder function, often mounted on a wheel or table, with a trough for proximal forearm support and an adjustable pivot system to promote trunk and shoulder girdle movement.
• Functional Dynamic Elbow Orthoses:
  • Designed to assist with both elbow flexion and extension during movement.

Wrist Orthoses

• Dynamic Wrist Orthosis with Dorsiflexion Assist: Modified long opponens splint aiding wrist extension while allowing normal wrist flexion.

Hand and Finger Orthoses

• Metacarpophalangeal Flexion Orthosis: Prevents metacarpophalangeal extension, essential for maintaining finger position.
• Metacarpophalangeal Extension Orthosis: Addresses finger drop conditions.
• PIP Extension and Flexion Stops: Limits flexion or extension at the PIP joint as needed for rehabilitation.
• Thumb IP Extension Assist: Supports individuals with finger and thumb drop due to radial nerve or posterior interosseus nerve injury.
• First Dorsal Interosseus Assist Orthosis: Keeps the index finger abducted and in opposition, promoting functional use of the hand.
