Background
Distal radius fractures (also called Kelei's fractures), usually the distal fracture piece is displaced to the dorsal side and the proximal side, the dorsal side is often compressed or the fracture is crushed, the operation usually selects the palmar approach, the dorsal side can not be directly reset, therefore, the inclination angle of the palm of the patient can not be recovered, thereby affecting the daily activities of the patient. The inclination angle of the radius palm refers to the included angle between the connecting line of the palm and the dorsal most distant point of the distal radius articular surface and the perpendicular line of the long axis of the radius in the wrist joint lateral plate, and the normal value is as follows: 10-15 degrees. The dip angle of the palm plays a crucial role in the flexion and extension of the wrist. If the normal dissection of the dorsal radius is to be restored, dorsal incision reduction or steel plate fixation is often required. For comminuted or complicated fracture bypassing with far end, two steel plates are often fixed on the palm side and the back side of the radius respectively, and then the angle between the two steel plates is adjusted, so as to complete the fixation of the palm inclination angle. Specifically, the applicant can refer to the patent of the invention with publication number CN209574853U, and the distal radius fracture angle adjuster is an angle adjuster in the reduction technology of the distal radius fracture steel plate. Above-mentioned scheme, to patient's operation wound big, the operation process is very loaded down with trivial details, and the expense of fixed two steel sheets is very high.

Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
An angle adjuster for distal radius fracture, as shown in fig. 1 to 5, comprises a first adjusting plate 1, a second adjusting plate 2 and an adjusting rod 3.
Referring to fig. 3, the first adjustment plate 1 is provided with mounting holes 101, and the mounting holes 101 are used for mounting screws, that is, the screws pass through the mounting holes 101 and are fixed on the distal radius fracture bone block, and keep the first adjustment plate 1 flush with the bone surface of the distal radius fracture bone block.
Referring to fig. 3, the second adjustment plate 2 is provided with adjustment through holes 201, and the adjustment through holes 201 are used for installing screws, i.e. the screws can be fixed on the proximal bone block of the radius fracture after passing through the adjustment through holes 201.
Referring to fig. 1 and 2, the second adjustment plate 2 and the first adjustment plate 1 are obliquely arranged to form a similar folded plate, and the second adjustment plate 2 and the first adjustment plate 1 have an inclination angle therebetween, which is in the range of 10 to 30 degrees, which is greatly related to a palm inclination angle of about 15 degrees. In actual manufacturing, the inventor adopts 15 degrees, and the angle is convenient to use. The bottom end of the joint of the first adjusting plate 1 and the second adjusting plate 2 is a fulcrum, so that the bottom end needs to be an arc surface, and the position is convenient to adjust.
Referring to fig. 1 to 3, the adjusting lever 3 is movably disposed in the adjusting through hole 201 of the second adjusting plate 2. Adjust pole 3 and pass through adjustment through-hole 201, its bottom can be directly downward, wears out second adjusting plate 2, thereby can contact the bone surface and form the contained angle at second adjusting plate 2 and bone surface. Regarding the structure of the adjusting rod 3, the present application provides two sets of solutions:
one is as follows: referring to fig. 1, 2 and 4, the adjustment lever 3 includes a lever sleeve 301 and a threaded inner lever 302, the lever sleeve 301 is mounted on the adjustment through-hole 201 of the second adjustment plate 2 through a locking device, and the threaded inner lever 302 is rotatably provided on the lever sleeve 301. The rod sleeve 301 is provided with an internal cavity and the threaded inner rod 302 is located inside the sleeve rod 301. The loop bar 301 plays a supporting role, so that the top end of the threaded inner rod 302 can be directly rotated conveniently, and the distance of the threaded inner rod 302 in the loop bar 301 can be controlled.
Preferably, the top end of the threaded inner rod 302 is provided as a rotating head and has anti-slip threads to facilitate rotation. The bottom end of the threaded inner rod 302 is rounded and the rounded end is in direct contact with the surface of the radius, but does not damage the periosteum of the radius. Because the position of the rod sleeve 301 in the threaded inner rod 302 needs to be adjusted, a window can be arranged on the side surface of the rod sleeve 301, a scale bar is arranged on the outer side of the rod sleeve 301, and scale lines are arranged on the side surface of the threaded inner rod 302. Each scale mark corresponds to a gear, and the three gears are totally arranged in the figure and can correspond to 5 degrees, 10 degrees and 15 degrees respectively.
The second step is as follows: the adjusting through hole 201 of the second adjusting plate 2 is a threaded hole, and the adjusting rod 3 is a threaded rod. That is, as shown in fig. 5, the adjustment lever 3 may be directly rotated. The solution is a simple solution for the adjuster, but it is inconvenient to quantify the rotation angle of the two adjusting plates, i.e. it lacks guidance.
During the use, paste first adjusting plate 1 on radius fracture distal end bone piece, the position of regulation pole 3 in second adjusting plate 2 is adjusted to the adjustment, selects suitable gear as required, makes its bottom and radius bone face contact, and at this moment, second adjusting plate 2 and bone face are the separation state, become certain angle, through the degree of depth of adjustment threaded inner rod 302 in loop bar 301 aforesaid gear promptly to the angle of adjustment second adjusting plate 2 and radius bone face is fixed this state. Fixing the first adjusting plate 1 on a distal bone block of the radius fracture by a plurality of screws and the like; the adjusting rod 3 is taken out to press the second adjusting plate 2, so that the second adjusting plate 2 is attached to the proximal end bone surface of the radius fracture, and the distal end bone block of the radius fracture can rotate along the axial direction with the fulcrum as the axial direction palm side and the distal end due to the fixation of the first adjusting plate 1 and the screw, namely, the palm inclination angle is recovered, so that the dorsal collapse and the defect are recovered, and the second adjusting plate 2 is fixed on the proximal end bone block of the radius by using the locking device. Through the series of operations, the anatomical form of dorsal comminuted fracture is restored while the palmar operation and the fixation of the adjusting plate are performed, and no additional operation incision and fixation of the adjusting plate are needed.
The adjustment lever 3 is not optional and the function of the adjustment lever 3 will now be described. The distance of the bottom end of the adjusting rod 3 extending out of the second adjusting plate 2 can be adjusted, and the distance is prepared for the second adjusting plate 2 to be jointed with the proximal bone block of the radius fracture in subsequent operation. Under the condition that the fracture does not reach the complete anatomical reduction, the fixed angle of the first adjusting plate 1 and the radius fracture far-end bone block is difficult to guarantee, if the adjusting rod 3 is not arranged, when the first adjusting plate 1 is attached to the radius fracture far-end bone block, the second adjusting plate 2 is difficult to ensure to be attached to the radius fracture near-end bone surface, and the reduction angle of the radius far-end palm inclination angle can not be guaranteed to meet the requirements.
It should be understood that the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as no structural conflict exists; and all such modifications and alterations are intended to fall within the scope of the appended claims.
