The recovery process after open lumbar fusion surgery consists of four main phases: sedentary rest, neutral stabilization, physical recovery, and flexibility exercises. The recovery time is generally 3~12 months. 1. Resting and recuperation: mainly for sedation and protection, lie flat on a hard board bed to keep the spine stable; turn over regularly, keep the chest, waist and hip in a straight line, and turn over axially to prevent the waist from twisting. Slowly start to try walking training, need to wear a waist cuff or support, strengthen the lumbar support. Try to avoid bending and other strenuous movements. 2. Neutral stabilization: slowly increase the patient’s lumbar spine tolerance, use the correct squatting posture, strengthen the lower limb Strength training, gradually restore the normal range of motion of the lumbar spine. 3. Physical recovery: focus on core muscles and basic physical exercise, and exercise painlessly for 30-60 minutes a day, so that the strength of the lower limbs can be fully recovered. 4. Flexibility Exercise: Start light lumbar spine flexibility exercise, strengthen the lumbar back muscle training, such as plate support, small swallow fly and other movements. Gradually recover to the preoperative level. It is recommended that the patient actively carry out treatment and rehabilitation training under the guidance of the doctor in time to avoid causing re-injury. Some fluctuations in the recovery process after lumbar spine surgery is a normal phenomenon, so there is no need to be nervous about a little soreness and stiffness in the lumbar region, and the pain is obvious or the symptoms persist for a long time and can not be relieved should go to the outpatient clinic for review.
