因先天畸形、創(chuàng)傷、退變、缺血或炎癥等原因造成髖關(guān)節(jié)軟骨破壞、關(guān)節(jié)間隙狹窄、股骨頭壞死塌陷，引起髖關(guān)節(jié)疼痛、功能障礙，保守?zé)o效，可通過(guò)人工髖關(guān)節(jié)置換術(shù)，緩解疼痛，改善功能。
Total Hip Replacement
全髖關(guān)節(jié)置換術(shù)
Your hip consists two main parts that fit together like a ball and a socket, the femoral head at the top of the leg, and the acetabulum in your pelvis.
我們的髖關(guān)節(jié)包括兩個(gè)部分：腿頂部的股骨頭和骨盆上的髖臼，就象一個(gè)球和一個(gè)臼相互匹配在一起。
A total hip replacement is usually done when severe damage from arthritis or injury has made it difficult to perform daily activities.
如果關(guān)節(jié)炎或損傷嚴(yán)重破壞了關(guān)節(jié)，使日?；顒?dòng)困難，往往需要進(jìn)行全髖關(guān)節(jié)置換術(shù)。
During the procedure, the femoral head and acetabulum are replaced with artificial components called prosthesis。 An artificial hip prosthesis consists a cup called the acetabular component and a metal stem called femoral component.
術(shù)中，用人工組件（假體）更換股骨頭和髖臼。人工髖關(guān)節(jié)假體包括一個(gè)杯（髖臼組件）和一個(gè)金屬柄（股骨組件）。
Your surgeon will begin by making an incision overline your hip, seperating the muscles and ligaments to expose the joint capsule.
首先， 術(shù)者沿髖關(guān)節(jié)作一個(gè)切口，分離肌肉和韌帶，顯露關(guān)節(jié)囊。
After incising the capsule, your surgeon will dislocate the femoral head from the acetabulum. He/she will remove any damaged cartilage or bone in the acetabulum, reshape the acetabular socket, and secure the acetabular prosthesis in place using special cement or screws.
切開關(guān)節(jié)囊肝，術(shù)者會(huì)將股骨頭從髖臼內(nèi)脫出來(lái)，然后去除髖臼內(nèi)損壞的軟骨和骨頭，將髖臼重新成形，并用特殊的水泥或螺釘將髖臼假體固定牢。
Turning next to the femur, your surgeon will remove the femoral head, shape the remaining femur to fit the prosthetic stem and secure the femoral component using cement or other techniques.
下一步處理股骨。術(shù)者將去除股骨頭，剩下的股骨成形，以與假體柄匹配，并用骨水泥或其它技術(shù)固定股骨假體。
Once both components are firmly in place, your surgeon will slide the prosthetic femoral head into it's acetabulum counter-part. Test the movement of your new hip joint, and verify that it is properly positioned with an X-ray.
當(dāng)兩邊的假體都安裝牢固，術(shù)者將股骨頭假體滑入髖臼相對(duì)應(yīng)的部分，活動(dòng)新的髖關(guān)節(jié)進(jìn)行測(cè)試，并用X線來(lái)證實(shí)位置安裝合適。
Your surgeon will then close the joint capsule, repair the muscles, place a drain in your hip to remove excess fluid and close the incision with stitches or staples.
術(shù)者隨后關(guān)閉關(guān)節(jié)囊并復(fù)位肌肉，放置引流管以去除過(guò)多的液體，最后通過(guò)縫線或皮釘關(guān)閉切口。
