Lumbar Osteoarthritis

腰椎骨關(guān)節(jié)炎

Lumbar osteoarthritis is a form of degenerative arthritis in the low back that causes pain, stiffness, and inflammation in the joints between vertebrae.

　　腰椎骨關(guān)節(jié)炎是一種腰椎的退變性關(guān)節(jié)炎，它會(huì)引起疼痛、僵硬，以及椎間關(guān)節(jié)的炎癥。

There are two facet joints on the back of each vertebra that connect the bones of the spine and allow for a small amount of movement. Wear and tear on facet joints in the lower spine causes the cartilage between the two bony sides of the facet joints to break down. Without cartilage, the bony parts of the joint rub together as the spine moves. As a result, the joint loses motion and the surrounding tissue becomes inflamed.

　　每個(gè)椎體的后方有兩個(gè)關(guān)節(jié)突關(guān)節(jié)，將脊柱的骨頭連接起來(lái)，同時(shí)允許少量的活動(dòng)。腰椎關(guān)節(jié)突關(guān)節(jié)的磨損和撕裂會(huì)導(dǎo)致關(guān)節(jié)突關(guān)節(jié)相鄰兩側(cè)骨面的關(guān)節(jié)軟骨破壞。如果沒(méi)有關(guān)節(jié)軟骨，當(dāng)脊柱活動(dòng)時(shí)，關(guān)節(jié)相鄰的兩塊骨頭之間就會(huì)摩擦。結(jié)果，關(guān)節(jié)運(yùn)動(dòng)功能下降，周圍組織出現(xiàn)炎癥。

Osteoarthritis of the spine commonly occurs as a result of aging, trauma to the spine, and repetitive movements. It does not always result in back pain. Symptoms of lumbar osteoarthritis include decreased back motion and flexibility, as well as stiffness and pain in the lower regions of the back. Back muscles may spasm to help stabilize the spine.

　　脊柱骨關(guān)節(jié)炎通常由于年齡老化、脊柱的外傷以及反復(fù)的活動(dòng)引起，它并不一定引起腰痛。腰椎骨關(guān)節(jié)炎的癥狀包括腰椎活動(dòng)能力和柔韌性的下降，以及腰部的僵硬、疼痛。為了幫助穩(wěn)定脊柱，背部的肌肉會(huì)發(fā)生痙攣。

Bone spurs may form on the surfaces of the facet joints as a response to joint pain and instability. These bone spurs can then irritate or compress nearby nerves in the spine, causing symptoms of radiating nerve pain.

　　關(guān)節(jié)突關(guān)節(jié)的表面可能形成骨刺，引起關(guān)節(jié)疼痛和不穩(wěn)。骨刺還會(huì)刺激或壓迫旁邊的脊神經(jīng)，導(dǎo)致放射性神經(jīng)痛的癥狀。

Lumbar osteoarthritis is a common cause of low back pain in people over age 60. Early diagnosis and lifestyle modifications are helpful in treating arthritic pain.

　　腰椎骨關(guān)節(jié)炎是60歲以上人群引起腰痛的常見(jiàn)原因。早期診斷以及生活方式的調(diào)整有助于治療關(guān)節(jié)炎性疼痛。
