In one embodiment, the skeleton sleeve pocket is sewn on the outer side of the arm sleeve 1, the connecting lining 13 is sewn on the inner side of the cut of the arm sleeve 1, the connecting lining 13 is made of elastic material, the arm sleeve 1 is made of cotton, the skeleton plate is made of aluminum alloy or plastic material, and the number of the wrist straps 4 is [1, 2 ].
In this embodiment, the framework plate is usually a plastic composite material, specifically, the framework plate may be a light aluminum alloy strip, and the implementing personnel in the field can bend the aluminum plate by using a wrench or other means to achieve the fine tuning and shaping effect in clinical use; the material of the skeleton plate may also be a plastic, and the skeleton plate is heated by a heating device, such as an induction heater, and then molded to adapt to the user, which is not limited specifically.
On the other hand, the application provides a use method of the super wrist joint splint, which comprises the following steps: sleeving an arm sleeve on the injured forearm of the patient in the initial stage of fracture; performing shape-fitting treatment on more than three skeleton plates with over-wrist joints in the circumferential direction of the injured forearm of the patient, respectively placing each skeleton plate into a corresponding skeleton sleeve pocket, and fixing each skeleton plate in the skeleton sleeve pocket; and after the middle period of fracture, taking out the skeleton plate of the super wrist joint from the skeleton sleeve pocket, and replacing the skeleton plate of the non-super wrist joint with the short wrist joint length to increase the range of motion of the wrist joint of the patient after fracture.
It should be particularly emphasized that the skeleton plate of the super wrist joint referred to in this application is a skeleton plate whose specific size can extend and fix the position of the wrist joint of the patient according to the length of the forearm of the patient, whereas the skeleton plate of the non-super wrist joint is a skeleton plate whose specific size cannot extend to the position of the wrist joint of the patient, that is, the skeleton plate of the super wrist joint and the skeleton plate of the non-super wrist joint can be divided into short, medium and long specifications, and the super wrist joint and the non-super wrist joint used by the current patient are selected and matched according to the length of the arm of the patient. It should be noted that the early stage of fracture can be specifically adjusted according to the actual condition of the current patient, the early stage of fracture is usually about 4 weeks, that is, the skeleton plate of the super wrist joint is fixed in the skeleton sleeve pocket around the arm sleeve in the early stage to ensure the absolute fixation of the wrist joint, and the skeleton plate of the super wrist joint can be detached from the skeleton sleeve pocket in the middle and later stages of fracture and replaced by a shorter skeleton plate which is not the super wrist joint to ensure the fixation function of the forearm; the limitation of the activity of the wrist is cancelled, and the activity of the wrist is intentionally increased, so as to achieve the aim of early functional exercise.
The foregoing description of the embodiments of the present application has been presented for purposes of illustration and description and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
