Description

  The present invention relates to a wrist joint fixture used for reducing or treating wrist joint pain, particularly TFCC (triangular fibrocartilage complex) damage, and more specifically, a user can easily wear it alone. The present invention relates to a wrist joint fixing tool that can securely fix a wrist joint for a long time.

  TFCC is called a triangular fibrocartilage complex, and is hatched in FIG. 4 for the sake of convenience, and is indicated by reference symbol A. It is located around the ulnar styloid process (ankle of the wrist) and is located around the joint disc and ligament. It is formed of a tendon sheath and plays a role as a cushion to alleviate the impact on the wrist.

  As shown in FIG. 4, in the vicinity of the wrist joint, the forearm bone A and the proximal carpal row B face each other, and the forearm bone B includes the ulna b1 and the radius b2. The proximal carpal bone row B includes a scaphoid bone c1, a lunar bone c2, and a triangular bone c3, and a triangular fibrocartilage complex (TFCC) C between the proximal carpal bone row C and the ulna b1. There is.

  TFCC damage may occur due to trauma (sprains or ulnar styloid fractures) and may occur due to degenerative damage (aging phenomenon) based on age-related changes. Symptoms appear as pain in the wrist (wrist joint side), especially pain in the pronation (internal twist) and pronation (external twist) of the wrist joint, and the pain is exacerbated during exercise.

  As TFCC damage due to trauma, inflammation may occur in the joint disk of the triangular fibrocartilage complex C, and this may contact the ulna b1 and the triangular bone c3 and cause strong pain. Further, as TFCC damage due to degenerative damage, the ulna b1 protrudes compared to the radius b2, and the triangular fibrocartilage complex C is pushed up and damaged by the ulna b1, which may cause strong pain.

  Treatment is basically conservative treatment (method without surgery), cast treatment or orthosis treatment is performed for the purpose of rest, and the course is observed with thermotherapy as rehabilitation, and these conservative treatments do not improve In some cases, surgical treatment is required.

  Thus, as one of orthotic treatments, wrist joint orthosis for the purpose of reducing and treating pain of wrist joint damage has been provided. For example, Patent Document 1 discloses a fixing tool that fixes a damaged or painful wrist joint part, and also shows that it can be applied to TFCC damage.

  In this invention, it is preferable that the said expansion-contraction part is provided with two expansion-contraction pieces cut | disconnected along the length direction toward the said window part side from the free end.

  In the present invention, the locking means may be constituted by one hook-and-loop fastener element provided at the non-stretchable part and the other hook-and-loop element extended to the free end side of the stretchable part.

  According to the present invention, since the wrist joint can be fixed with the wrist ankle exposed from the window portion of the wrist belt, the wrist belt is not moved from the fixed position by the movement of the wrist joint even when used for a long time. There is nothing.

  In addition, by providing a cushion part around the window part, it is possible to accurately compress the periphery of the ulna causing pain of TFCC damage while appropriately limiting the movable range of the wrist joint. Blood circulation disorders and discomfort can be avoided.

  Furthermore, when wearing, the wrist belt window can be positioned accurately with respect to the affected area by applying the wrist to the ankle, and locking means such as hook-and-loop fasteners are provided on one end and the other end of the wrist belt. Therefore, they can be easily mounted by overlapping their end portions.

  Furthermore, since the expansion / contraction part is extended with two expansion / contraction pieces formed with locking means such as hook-and-loop fasteners on the free end side, one expansion / contraction piece is used for temporary fixing, and the other expansion / contraction piece Can be easily mounted while properly adjusting the tightening force of the wrist belt.
