There are two main types of lumbar spine surgery, one is minimally invasive simple nucleus pulposus removal and the other is lumbar spine internal fixation and fusion surgery. The two types of surgery have the same functional exercise after surgery. 1, within 3 weeks after surgery, more bed rest to facilitate soft tissue healing. 3 months are not allowed to carry out larger exercises. During the period of bed rest, more functional exercises of both lower limbs should be performed to avoid the occurrence of deep vein thrombosis in the lower limbs. 2.When you get up within 3 months, you need to bring a lumbar girth. When you are bedridden, you do not need to bring a lumbar girth, which is mainly for local protection and stabilization of the spine, but the lumbar girth will cause atrophy of the lumbar back muscles, so you need to carry out exercises for the lumbar back muscles. In prone position, lift the right lower limb backward, insist on 5-6 seconds and then put it down, then lift the left lower limb backward, insist on 5-6 seconds and then put it down. Each time each side of the lower limb exercise 15 times, two times a day, if no discomfort, you can increase the number of times each time. 3, 3 weeks later for the lumbar spine fixed surgery patients to carry out moderate functional exercise of the waist, that is, multi-angle lumbar exercise. Such as left and right lateral bending, back and forth bending, left and right turning, twice a day for 10 minutes each time. For patients with simple nucleus pulposus removal, they need to prevent recurrence and be careful when performing lumbar exercises. Most patients can recover from simple lumbar back exercises due to the small impact of surgery. All functional exercises should be done with the strength they can bear, do not rush, and can gradually use increased exercise after adaptation. 4, pay attention to the lumbar region to keep warm. If the lumbar pain and discomfort, hot physiotherapy can relieve the symptoms.5 that is, 5, protect the lumbar region. Reduce prolonged standing, sitting, walking, less weight, do not bend too much (preferably squatting instead of bending), do not sleep too soft bed, correct bad posture. The lumbar spine is also an important organ of the human body, and we should care for our lumbar spine like we care for our heart, lungs, stomach, etc., especially after surgery.
