Digit pad and method for treating trigger finger and trigger thumb
View Patent ↗A digit pad, and a method, for treating trigger finger and trigger thumb includes a digit band which is slid over the affected digit to a position between the PIP and the MCP joints and a palm pad which extends from the proximal end of the digit band toward the wrist, the palm pad being dimensioned and positioned to overlie a portion of the palm to at least cover the A 1 pulley, the proximal end of the palm pad extending beyond the A 1 pulley, but not beyond the proximal palmer crease, the palm pad being at least as wide as the A 1 pulley and being formed of a material which is soft, flexible, resilient and has a sufficient density to protect the palm area which it overlies. A patient wears the digit pad on the affected digit substantially continuously during waking hours until the condition resolves.
1. A method of treating trigger finger and trigger thumb comprising the steps of:
positioning, on each affected digit of a patient, a digit pad comprising a digit band adapted to be slid over the free end of the affected digit to a position wherein the proximal end of the band is at the MCP joint of the affected digit and a palm pad unitary with said digit band, said palm pad extending from the proximal end of the digit band toward the wrist, said palm pad being dimensioned and adapted to be positioned to overlie a portion of the palm to at least cover the A 1 pulley of the affected digit, the proximal end of the palm pad extending beyond the A 1 pulley, but not beyond the proximal palmer crease, said palm pad being at least as wide as the A 1 pulley and being formed of a material which is soft, flexible, resilient and which has a sufficient density to protect the palm area which it overlies; and
said patient wearing said digit pad substantially continuously during waking hours for a period of time sufficient to resolve the trigger finger or trigger thumb condition of the affected digit.
2. A method, as claimed in claim 1 , wherein said time sufficient is in the range of six to eight weeks.
3. A method, as claimed in claim 1 , wherein wearing said digit pad substantially continuously during waking hours comprises wearing said digit pad substantially 24 hours a day, excepting when sleeping, washing and bathing.
4. A method, as claimed in claim 1 , wherein said digit band is positioned between the PIP and MCP joints of the affected digit.
5. A method, as claimed in claim 1 , wherein said digit band is endless.
6. A method, as claimed in claim 1 , wherein the proximal end of said palm pad extends to the neck of the metacarpal bone of the affected digit.
7. A method, as claimed in claim 1 , wherein said digit pad extends, in width, a sufficient distance on each side of the A 1 pulley of the affected digit to substantially continuously overlie the A 1 pulley as the affected hand is used.
8. A method, as claimed in claim 1 , wherein the width of said digit pad is from 1.5 to 2 times the width of the A 1 pulley of the affected digit.
9. A method, as claimed in claim 1 , wherein said digit pad tapers from said digit band toward its proximal end, the width of said pivot pad being greatest at the digit band.
10. A method, as claimed in claim 1 , wherein the proximal end of said digit pad defines a gentle curve.
11. A method, as claimed in claim 1 , wherein at least said palm pad is formed of neoprene sheet material laminated on opposing faces with nylon fabric.
12. A method, as claimed in claim 1 , wherein said digit band and said palm pad are formed of neoprene sheet material laminated on opposing faces with nylon fabric.
13. A method, as claimed in claim 1 , wherein said digit band is dimensioned and adapted to be positioned between the PIP and MCP joints of the affected digit and said digit pad extends, in width, a sufficient distance on each side of the A 1 pulley of the affected digit to substantially continuously overlie the A 1 pulley as the affected hand is used.
