This sizing chart provides a correlation between digit circumference measured with a tape measure at the PIP joint level and comfortable fit for individuals donning a KnuckleUp/ThumbUp. For the same circumference digit, there is overlap in what is the most comfortable sized orthosis based on digit length and taper. Use this only as a general guide when placing clinic orders, however, for individual patients, confirm size before ordering using the KnuckleUp/ThumbUp Digit Sizer Set. As a soft,neoprene-based medical orthosis that contacts skin and can absorb perspiration and skin oils, the KnuckleUp/ThumbUp are not exchangeable for larger/smaller sizes.

The evolution of dynamic extension orthoses over 80 years. The PIPro represents the modern addition to a therapist’s options with its circumferential design for edema reduction and warmth. Removal of the raised internal sewn seam improves patient comfort over older designs and creates more uniform compression. The PIPro can also be end trimmed without unravelling and is effective even in contractures under 15 degrees where older tube splints lose force.
