The WE swan neck splint ring prevents hyperextension of the PIP and/or DIP finger joints while allowing full flexion.
More than one WE swan neck splint ring can be worn on one hand without any problems. The splints come in the dorsal width of 3.5 mm, 5 mm and 8 mm.
The swan neck splint can also be combined on the PIP and DIP joint at the same time and on several fingers simultaneously. The splints can be joined together with one small hinge on the dorsal side. In contrast to model 5032 where the length between the two phalanges (PIP and DIP) can be determined, with this model the length is determined by the specified measurements of the finger.
With this model two swan neck splints are connected by two bilateral hinges. Hyperextension of the PIP joint is blocked while flexion remains possible. Unlike model 5033, model 5032 allows for some hyperextension in the DIP joint. The bilateral hinges give the DIP join a lot of bilateral support. With this model, the length between the two phalanges (PIP and DIP) can be determined, which makes the model very suited for shorter fingers such as the little finger.
Adding one (code 5015) or two (code 5016) lateral supports to the side(s) of the swan neck ring corrects (bi)lateral instability in the PIP and/or DIP joint. The lateral support can also be used to correct a (non fixed) deviation of the PIP-joint. The lateral support is placed opposite to the direction the finger deviates. For the ulnar or radial deviation of the DIP joints, the boutonnière splint ring (code 5014) is worn sideways to correct and prevent further deviation.
The WE boutonnière splint ring is the answer in mild cases of boutonnière and mallet finger deformations. Flexion of the PIP or DIP joints is restricted and the finger is kept in extension by bringing the joint and finger into a straight position. This splint is also often used on the DIP joint to redress and prevent ulnar or radial deviation. It is important that the deviation can still be easily corrected.
The WE Extension splint model 5017 keeps the PIP joint in extension without putting pressure on the joint itself. This model is used for the PIP joint but can also be extended with a distal addition towards the top of the finger (model 5021).
By extending the extension splint ring (code 5017) with a distal addition the Arthrodesis splint is created. This splint keeps both the PIP and DIP joint in extension.
The dynamic extension splint ring can be applied when the extensor tendons fail to perform. Coil springs placed laterally to the PIP joint on both sides help increase PIP extension and reduce flexor tendon tightness. In case of post-operative flexion contractors, wearing of these rings is not the right treatment. When chronic conditions occur and long-term splinting can be of help then the We dynamic extension splint rings offer a solution.
The anti-trigger ring restricts movement of the flexor tendon at the MCP joint. Often indicated due to flexor tendon tenosynovitis. Without limiting the range of movement of the rest of the hand and fingers, locking or clicking of the flexor tendon at the A1/A2 pulley is avoided.
The We eternity splint ring functions as both a buddy ring and a swan neck ring at the same time. The distal ring loops around the middle phalanx thus creating more leverage to redress the ulnar finger involved.
The pulley ring can be applied in the case of flexor tendon trauma when the annular Pulley (A2 and A4) is limited in proper tendon function. The WE pully ring takes over the function of the A2/A4 pulley. This unique design with hinge and lock holds the ring perfectly in place behind the joint and the finger becomes functional again. Being slightly oval in shape guarantees blood circulation.
The spiral splint can be applied as a swan neck ring or an extension splint ring depending on the way the spiral is worn. This type of splint can be a solution for instable IP joints as well as other joints in the case of nodules. Code 5022 is also use for the thumb addition to the wrist braces, where the spiral supports the MP joint proximally and distally.
The anti-dropping finger splint easily supports a dropping finger into extension by using the stability of the lateral MCP joints related to the one causing the problem.
The bridge splint ring is used when more than one of the MCP joints is unstable or more leverage is desired. It combines the strength and stability of 3 (code 5012) or 4 (code 5038) MCP joints. Also, when the PIP joints are thickened, the open construction offers a solution where closed rings fail.
The buddy ring connects one instable finger to a stable finger using its stability to join up and thereby improve the hand function. These rings can vary in width and follow the web space if needed. This is often used against ulnar deviation of MCP V.
