Lumbar decompression and internal fixation and fusion surgery involves a rest period of at least three months. Bone fusion takes some time to grow and heal, and bone fusion in the lumbar spine usually takes about three months. Recovery time varies for each person’s body type. This is determined by imaging tests and a physical examination. During the three months, you should strictly follow the doctor’s instructions for bed rest and perform functional exercises in bed according to the doctor’s instructions. If the recovery is good, you can get out of bed and exercise after three months; if the recovery is slower, it will take a little longer. Patients should have regular follow-up appointments so that the treatment will work well. Bed rest is required for 3 months after surgery. The waist cuff can be removed during the bed rest period and should be worn for the rest of the time. After 3 months, the patient will be seen in the outpatient clinic and can gradually remove the waist cincher if the healing process is smooth. Gradually removing the waist cincher means not to take off the protection of the waist cincher immediately, but gradually reduce the time of wearing the waist cincher, such as going out with the cincher at home, and then take off the waist cincher completely after gradual adaptation. In addition, after resuming work, do not stand for a long time and sit for a long time. The rest time of lumbar disc fusion surgery needs to consult a professional orthopedic surgeon, do not blindly activity and rest.
