Problems solved by technology

It is then not possible to completely remove the implant, which can be troublesome especially during subsequent surgical interventions
[0008] Furthermore, in most cases, current devices require immobilization of the wrist with a splint or plaster cast for 6 to 8 weeks, which prevents any early mobility and causes wrist stiffness

Embodiment Construction

[0029] An advantageous manufacturing example of the scapholunate bone stabilization implant according to the invention is described with reference to said figures, but this example is by no means limiting.

[0030] The scapholunate stabilization implant comprises an oval plate 1 made of elastically deformable material, at least one hole 2 for a fastening bolt 3 is provided at the end of the plate, and the plate The middle part has an opening 4 bounded by two opposite sides 5 or 5' for a spring 6 connecting two distant points such as two opposite points of said sides 5 or 5' together , the spring is placed in the opening 4 along the diagonal.

[0031] According to the example shown, each end of the scapholunate stabilization implant 1 is provided with two spaced holes 2 for passage of fastening bolts. The fastening bolts 3 are preferably of the self-tapping double threaded type, so that the tapping of the advantageously conical hole 2 can be carried out automatically when they...

Abstract

A scapholunate stabilization implant is characterized by being composed by an oval plate (1) which is made from elastic deformation materials, wherein the ends of the plate are installed with at least one hole (12) for the passage of a fastening bolt (3) and the central part of the plate is provided with an opening (4) defined by two opposite lateral parts (5, 5'). A spring (6) disposed in the opening along the diagonal line connects the two distant points of the lateral parts (5, 5').

Description

technical field [0001] The present invention relates to a scapholunate stabilizing implant (implant for stabilizing the scapholunate). Background technique [0002] The scaphoid and lunate are two of the eight bones that make up the carpus (wrist). During a severe fall that involves a wrist strike, the ligament that connects the two bones, called the scapholunate ligament, is prone to damage, such as nicks, tears...Damaged formation of this ligament causes early osteoarthritis stability. [0003] If this injury is diagnosed early by the surgeon, the surgeon can perform stitches, which can only be performed while the ligament is still being supplied with blood. [0004] However, if this injury is not treated promptly, the damage caused by the two bones rubbing against each other may be irreversible, and arthrodesis or even resection of both bones may need to be contemplated. [0005] Prosthetic devices are also known which allow replacement of the scapholunate ligament. ...
