Why splint Swan Neck Deformities?
...to allow free functional grasp without manual movement of the affected joints from locked hyperextension to flexion.
...to limit additional damage to the joint which occurs when the finger repeatedly moves from flexion to hyperextension.
...to decrease swelling of the P.I.P joint. Decrease in swelling may occur in many cases after several months of splint wear.
How does the Murphy® Ring Splint work? After being fit correctly on the finger
...the single wrapped end prevents the finger distal to the P.I.P. joint from moving into hyperextension, thus preventing the digit from becoming locked in the swan neck position.
...the double wrapped end serves as an "anchor" to secure the splint proximal to the P.I.P joint.
...the junction of the ends of the splint, under the P.I.P joint, does not block movement but allows free flexion of the digi t.
How does the Murphy® Ring Splint differ from other anti-hyperextension splints on the market?
Murphy® Ring Splints are made from high grade stainless steel spring wire. Stainless Steel wire (a hypoallergenic materia l) allows us to make splints that are durable, hold their shape, and do not rust. They can be worn in water. They are easily cleaned with cool, soapy water. They are cosmetically attractive, adjustable, and re-adjustable multiple times, and come in s tandard American ring sizes from 2-13. They can be worn on many fingers of the hand at the same time. They can be used on the P.I.P and D.I.P. joints to provide strong lateral stability and joint protection. They can also be used upside down on the D .I.P joint to provide strong prehensive stability.
Each splint is individually spun on a processing machine to make our trademark shape. All edges of the wire are round to allo w the pressure of the splint to be spread over a larger skin area to reduce chance of skin breakdown during use. The tips of the wire where the splints are cut from the wire spool, are smoothed by hand to prevent any sharp edges from touching the pat ients'' skin. After thorough inspections, the splints are then sent through and electro polishing process which gives them the ir shiny, jewelry like appearance.
Indications: Swan-neck deformity of PIP joint
How to size.
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.
