Lumbar - Partial Discectomy
腰椎間盤部分切除術(shù)
Introduction （介紹）
A herniated lumbar disc can push on spinal nerves and cause severe, shooting, leg pain, numbness, and/or weakness. Removing part of the herniated disc in a partial discectomy procedure can prevent the disc from irritating the nerve.
腰椎間盤突出會擠壓脊神經(jīng)引起嚴重的槍擊樣的腿痛、麻木和/或無力。在椎間盤部分切除術(shù)中，去除部分疝出的椎間盤可以避免椎間盤對神經(jīng)的激惹。
Incision （切口）
An incision is made in the middle of the low back to expose the lumbar vertebrae above and below the herniated disc. Next, surgical instruments are used to remove a portion of the lamina to provide access to the herniated disc.
在腰后部正中作切口，顯露突出椎間盤上下的椎骨。然后用手術(shù)器械將一部分椎板切除，以顯露疝出的椎間盤。
Excision （切除）
The herniated portion of the disc is removed. This relieves the pressure on the compressed nerve.
切除突出部分的椎間盤，這就解除了神經(jīng)的壓迫。
Stabilization （穩(wěn)定）
The incision is closed and dressed to complete the surgery. Patients usually notice rapid relief of leg pain; however numbness may occasionally persist for several weeks before fading away. Patients should take care to avoid heavy lifting and strenuous exercise for at least 6 weeks following the procedure.
關(guān)閉切口并包扎，手術(shù)結(jié)束。患者往往發(fā)現(xiàn)腿痛迅速緩解，然而麻木往往需要持續(xù)數(shù)周才會消退。術(shù)后至少6周內(nèi)，患者應(yīng)注意避免負重和劇烈活動。
