Murphy ring finger splints

Designed to help correct a swan-neck deformity of the PIP joint.

These finger splints restrict abnormal hyperextension while allowing active flexion at the PIP joint. Can be used on the PIP and DIP joints to provide lateral stability and joint protection. Can also be used upside down on the DIP joint to provide prehensive stability. Made from high-grade stainless steel spring wire, Murphy Rings hold their shape, do not rust, and are durable and attractive. Murphy Ring Splint Kit contains one of each of the 12 sizes and a ring sizer in a plastic partitioned container.

Murphy rings restrict abnormal hyperextesion while allowing active flexion at the PIP joint.

To determine size, use the Murphy ring sizer or a standard ring sizer to measure the involved joint. For half sizes, use the next larger size.
Size 2 SN-A525-48	Size 3 SN-A525-49	Size 4 SN-A525-50	Size 5 SN-A525-51
Size 6 SN-A525-52	Size 7 SN-A525-53	Size 8 SN-A525-54	Size 9 SN-A525-55
Size 10 SN-A525-56	Size 11 SN-A525-57	Size 12 SN-A525-58	Size 13 SN-A525-59

To determine size, use the Murphy ring sizer or a standard ring sizer to measure the involved joint. For half sizes, use the next larger size. Alternative sizing method is to measure the circumference of the joint in centimeters (see chart below).
Ring Size	Circumference of joint	Ring Size	Circumference of joint	Ring Size	Circumference of joint
2	4.1cm	6	5.3cm	10	6.6cm
3	4.4cm	7	5.7cm	11	6.9cm
4	4.7cm	8	6.0cm	12	7.2cm
