To choose a size likely to fit your finger, wrap a tailors measuring tape around the finger joint you are treating. Pull lightly so the tape conforms smoothly around your finger. Use the sizing chart to find the size(s) closest to your measurement. The difference between sizes is very small and you may need more than one size for an accurate fit. The difference in circumference from one size to the next is only 1/16 to 1/8 and can be affected by minor swelling or by how the splint is worn. The sizing method described is not guaranteed to be 100% accurate for all fingers. Oval-8 Finger Splints may need to be adjusted by a healthcare provider trained in fitting splints for the most successful treatment.NOTE: Oval-8 Finger Splints are not recommended for children under the age of 4 as they may cause choking if swallowed. Do not use an Oval-8 over an open sore or wound. Wait until any significant swelling has subsided before wearing. Please discuss the use of this splint with your health care provider.
