[Support and Stabilization] The finger splint is designed to effectively straighten and immobilize the finger knuckles, providing protection for both finger and thumb joints. [Indications for Use] This finger extension splint is ideal for reducing tightness in PIP joints, managing flexion staining, and addressing corsage deformities. It maintains assisted extension at the PIP joints while allowing active flexion, making it suitable for soft tissue injuries of the PIP joints and potential flexion deformities. [Size Options] - Size S: Finger circumference below 5.5cm - Size M: Finger circumference 5.5-7cm - Size L: Finger circumference above 7cm Choose from three sizes to ensure a proper fit for your finger joints. [Key Features] 1. Coil Spring Design : Equipped with dynamic coil springs on both sides of the PIP joint for balanced support and strength, enabling active flexion while aiding in extension. 2. Versatile Usage : Designed for various conditions related to joint extension dysfunction. 3. Practical Support : Provides support for PIP joint buckling contracts and delivers additional metacarpophalangeal (MP) joint support. 4. Soft EVA Pads : Curved proximal and distal pads equally distribute pressure for comfort. 5. Spring Coil Mechanism : Utilizes the elasticity of the spring to straighten and stabilize the finger while allowing for controlled rehabilitation through active bending. [Material and Applications] Constructed from durable EVA and stainless steel, this splint is suitable for conditions such as sprained fingers, fracture fixation, underextended fingers, hammer fingers, and tendon ruptures. [Dimensions] - Size S: Maximum circumference of 5.5 cm / 2.2 inches - Size M: Finger circumference 5.5-7cm / 2.2-2.8 inches - Size L: Circumference greater than 7 cm / 2.8 inches
