Hip replacement Image 3684 PH, An A-P X-ray of a pelvis showing a total hip joint replacement. The right hip joint (on the left in the photograph) has been replaced. A metal prostheses is cemented in the top of the right femur and the head of the femur has been replaced by the rounded head of the prosthesis. A white plastic cup is cemented into the acetabulum to complete the two surfaces of the artificial "ball and socket" joint. 
 
Although not the case here, hip prostheses can also be made of a ceramic material which rarely wears out during the patient's lifetime.  During the operation, a bonding cement is used to fix the metal prostheses into the shaft of the femur and the plastic cup to the acetabulum (socket in the hip bone). One of the leading reasons for hip replacement is osteoarthritis of the hip joint in which virtually all of the cartilage around the top of the femur bone deteriorates due to wear over time, leaving a grinding bone-on-bone situation with the bone surfaces becoming roughened leading to pain and stiffness.  Narrowing of joint space (the space between the acetabulum and the head of the femur) is also a feature of osteoarthritis. There may be other changes which are not entirely clear on this A-P X-ray, which probably should be reported together with lateral X-rays of the hips, or with modern computerised imaging techniques.

股関節置換術 骨盤のA-PX線で股関節の全置換術を示す画像 3684 PH右股関節(写真左側)交換。右大骨の上部に金属製の突起が固着し、大骨の頭部が丸い頭に置き換えられている。白いプラスチック製のカップをアセタブルムにセメントし、人工の「ボールとソケット」ジョイントの2つの表面を完成させる。股関節は、この症状ではないが、患者の生前にほとんど摩耗しないセラミック素材で作られることもある。手術中、接着セメントを使用して、大骨の軸に金属の突起を固定し、プラスチックカップを部に固定します。股関節置換術の主な原因の1つは、股関節の骨関節炎であり、大骨頂部のほぼすべての軟骨が時間の経過とともに摩耗により悪化し、骨表面が痛みと硬さにつながるため、骨が粗くなるという骨伝導状態が残る。関節腔の狭(大骨と大骨の間の空間)も変形性関節症の特徴である。このA-P X線で完全には明らかでない他の変化がある可能性があり、これはおそらく腰の側面X線、または最新のコンピュータ画像技術と一緒に報告する必要がある。キーワード:総腰置換術、筋縮術、骨関節炎、X線撮影。人工股関節などの移植は、そのようなデバイスの侵襲的な性質のために、一般的に広範囲に調節されている。腰置換術のX線、股関節置換術のHIP代替術のImage 3684-PH。
