The burden on the scapula, which is made up of sinful bone plates, is so great that by 9 o'clock, the bone of the scapula has been destroyed. Furthermore, anchoring artificial metal replacements requires large amounts of highly toxic bone cement. Regarding dislocation after surgery, cases of dislocation are often reported due to the weak bond between the conventional artificial femoral head and the blenoid component. Furthermore, satisfactory results have not been obtained regarding the range of motion of the shoulder joint after surgery.

On the other hand, in our connected artificial shoulder joint, the sliding part of the artificial femoral head has a convex curved elliptical surface, and the blenoid component has a shape close to a concave curved ellipsoid, so it has a structure closer to that of the original shoulder joint. ing. Furthermore, the artificial femoral head is made of ceramics, which is lighter than metal, and fits better into the bone, so bone cement is not required for anchoring. HDP
Only a small amount of bone cement is used to anchor the manufactured blenoid components. Furthermore, the artificial ligament that connects the artificial femoral head and the blenoid component is far superior to metal-to-metal connections in terms of lightness, strength, and compatibility with the living body. f, 1. The artificial ligament to be used is Terylene or carbon fiber.2 Terylene, a type of synthetic polyester, has tissue conductivity comparable to that of carbon fiber, which is currently used in the world.
It has an elongation rate of 5%, the same as that of living ligaments, and has already been used as a material for artificial blood vessels, and its safety in living bodies has been proven. In particular, LeedsKeio is made from terylene.
) The artificial ligament is made of thread (st) using Terylene filament with a diameter of 8-10/l
rand) and plain weave it into a mesh structure, but the disadvantage of terylene is that it has a poor grip on new tissue induced by one tissue, so it has a structure most suitable for gripping proliferated tissue, that is, approximately 2 .5 x 2.5mm mesh. - structure, and the excessive elasticity of the mesh structure is also solved by using a plain weave, where the warp threads support the stress applied to the ligaments, and the weft threads play a role in reducing warp slippage. Furthermore, the artificial ligament has a tubular structure (tube) with a diameter of 10 mm, and a new ligament with a desired shape is induced. Also, fatigue as a material (fat
Regarding the problem of ``Igue'', the tissue was induced before the fatigue phenomenon occurred. It has been confirmed in animal experiments that the new ligament has a strength greater than that of the original ligament, and it has already been used clinically to treat knee joint ligament injuries, with excellent results reported. Regarding the artificial ligament, please refer to the magazine Knees (2
): 240-249.1983, and is a known fact.

Regarding dislocation after surgery of the artificial shoulder joint, no dislocation can occur between the artificial femoral head and the Bremade component, which are connected by the artificial ligament. Regarding the range of motion of the joint, the design of the present invention is designed with small holes in the sliding part, allowing a range of motion that is close to normal. In other words, the present invention relates to shape, material, connection style, and movement style.

It is a revolution in conventional technology. f^j9 Regarding the method of fixing the artificial ligament, on the blenoid component side, create a knot at the edge of the artificial ligament to prevent it from coming off, then bury it in the scapula, and on the artificial bone head side, attach the excess artificial ligament to the stem. 1.The artificial ligaments shall be tied together using strong nylon thread, etc. At this time, approximately 5 mm of internal and external play of the artificial ligament is left between the sliding surfaces of the artificial femoral head and the Bremade component.
