Description
滑液ジョイントは、哺乳類のジョイントで最も一般のタイプであって、ほとんど全ての肢関節を代表する。接触させることは浮上する前記、大腿骨の骨(頭大腿骨)の骨盤、寛骨臼および接触表面は滑らかで丸くて、関節軟骨によってカバーした。
滑液膜はジョイントをカプセル化する。そして、股関節腔を形成する。そして、それは滑液流体を含む。外側で、滑液膜は繊維のカプセルおよび靭帯である。そして、関節カプセルを形成する。
年齢および磨耗については、関節軟骨は、緩衝装置および油をさされた表層としてより効果的にならない。異なる変形性関節症(例えば関節炎、osteoartrithisまたは骨関節症)は、悪化を加速する。
人工器官のゆるむことおよび/またはずれは、例えば落下しているかまたは腰の迅速な動きを作っている患者から、または、身体の大食細胞反応によって股関節に配置されている異常な圧力によって誘発されることができる。
そして、圧力は、応力によって生じる変化の比率である。
3e図の図示した実施例において、3f、安定させている部材668が、しかしながら、大腿骨の骨の切られた表層および大腿骨の骨の外面と接触してあるために適応すること、安定させている部材668が本願明細書において実施例のいずれかと関連して用いられて、大腿骨の骨の切られた表層を接触させるだけであるかまたは大腿骨の骨の外面を接触させるだけであるために適応することは、等しく考えられる。安定させている部材668は、切られた表層との接触によって、放射状に大腿骨の骨の外面との接触によって軸方向に更に医療装置を安定させる。安定させている部材は完全に大腿骨の骨7の外側を囲むために適応することができるかまたは全ての切られた表層610をカバーしていることができる、または、安定させている部材は各々切られた表層のより小さい部分または大腿骨の骨7の外面をカバーしている複数の部から成ることができる。図3eおよび3fの図示した実施例において、医療装置は図3cに関して開示される補綴股関節接触部分45と関連して示される、そして、3d、しかしながら、図3eおよび3fに示される医療装置が図3a、3bまたは10、11開示される補綴股関節接触部分45と関連して用いられることは等しく考えられる。
