Fingers are categorized by residual position into three types: thumb, proximal, and distal. The model you choose directly affects fit and function.<\/p>\n

Thumb<\/strong> Carries about half of hand function and drives grip and opposition. The Thumb exoskeletal finger is designed for thumb loss, restoring opposition and grip.<\/p>\n

Proximal<\/strong> Sits near the palm and usually involves a larger loss, requiring more stability and joint trajectory control. The Proximal exoskeletal finger focuses on joint motion and fit.<\/p>\n

Distal<\/strong> Is the fingertip segment and the most common site of loss. The Distal exoskeletal finger balances a natural contour with a light, well-fitted design for fine movements.<\/p>\n

For a loss limited to a single segment (e.g., only the fingertip), the one-segment (\u201c\u4e00\u8282\u201d) option offers a lighter, simpler structure.<\/p>\n

Selection Criteria<\/h2>\n
    \n
  • Residual position and length: identify the missing segment and how much remains.<\/li>\n
  • Function: whether full opposition and grip are needed, or mainly appearance and assisted motion.<\/li>\n
  • Use case: strength and weight requirements differ for daily life, work, and sports.<\/li>\n
  • Hand shape and size: refined designs suit Asian hands better.<\/li>\n<\/ul>\n

    If uncertain, book a one-on-one video consultation; a professional will confirm your situation and recommend a model. Data collection and molding take only 10\u201320 minutes, with no need to visit in person\u2014the full process is completed by courier.<\/p>\n
