本発明は１人間の肩関節全置換術に際して使われる肩甲
骨関節窩の人工置換物、すなわち、ブレノイド・コンポ
ーネントに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glenohumeral prosthesis, ie, a blenoid component, for use in total shoulder arthroplasty in a human.
ところで、慢性関節リウマチ、腫瘍、変形性関節症等の
病変におかされ、肩関節を構成しているふたつの要素、
すなわち、肩甲骨関節窩、及び」二腕骨骨頭が軟骨・骨
の破壊を受け機能不全に陥った場合、肩関節全置換術を
行い、新たな肩関節をつくる試みは、古くから先達によ
り行われて来た。By the way, due to lesions such as rheumatoid arthritis, tumors, and osteoarthritis, the two elements that make up the shoulder joint,
In other words, when the glenoid fossa of the scapula and the head of the bihumeral bone become dysfunctional due to cartilage and bone destruction, our predecessors have long attempted to perform total shoulder arthroplasty and create a new shoulder joint. I came.
今回、われわれは１機能解剖、及びバイオメカニカルな
観点から肩関節をとらえ、以下に述べる発明に至った。This time, we approached the shoulder joint from a functional anatomical and biomechanical perspective, and arrived at the invention described below.
本来、肩甲骨関節窩は、楕円球凸面を呈する」ユ腕骨骨
頭が、肩関節の運動に際して、ボールがころがる様な回
転運動をしたり、横すべり運動をしたり１回旋運動をし
たりする場を提供しているが。Originally, the glenoid fossa of the scapula exhibits the convex surface of an elliptical sphere.It is a place where the head of the humerus makes a rotational movement like a rolling ball, a side-sliding movement, and a rotational movement when the shoulder joint moves. Although it is provided.

号に記載された様な上腕骨人工骨頭を発明したが。By the way, we have already filed the patent application 1973-2n, +h3.
He invented an artificial humeral head as described in the issue.
本発明はそれと対をなし、肩関節全置換術に使われるも
のである。The present invention is a companion to that technique and is used in total shoulder arthroplasty.
本発明において、その摺動部は凹曲面を呈し。In the present invention, the sliding portion has a concave curved surface.

レノイド・コンポーネントは、その形状において。By the way, in the conventional artificial bihumeral head, the femoral head has a regular spherical convex shape, and the corresponding blenoid component has a regular spherical concave shape.1 The relationship between the two is a so-called pole and socket, and 1 The mechanism is very different from that of the shoulder joint. That is, the original motion mode of the shoulder joint is a rolling motion similar to a rolling ball, a sideways sliding motion, and two rotational motions, and the shape of the artificial femoral head and blenoid component required by such a shoulder joint.
人工骨頭は楕円球凸面を、ブレノイド・コンポーネント
は凹曲面を呈するものがめられており。The artificial femoral head is designed to have an elliptical convex surface, and the blenoid component is designed to have a concave curved surface.

難い構造となっている。Conventional prosthetic head and blenoid components do not adequately meet this need. , furthermore, the blenoid component of the present invention has 3 to 5 crest-like wings,
When inserted into the scapula, the structure prevents abnormal rotational movement and makes it difficult to remove.
また本発明は、たがいに鏡面関係にある右肩用。Moreover, the present invention is for the right shoulder which has a mirror surface relationship with each other.
左肩用の別々のコンポーネントがつくられている。A separate component is created for the left shoulder.
