Walking straight back with a large weighted dumbbell one month after internal fixation of a lumbar I compression fracture has the potential to cause recompression. It takes at least 3 months for the fracture to heal after internal spinal fixation surgery, so weight bearing during this time has the potential to aggravate the injury and cause re-injury. For one month after surgery, rest is the mainstay, and bed rest is preferred except for activities such as going to the bathroom where you must get up. During the period of bed rest, attention should be paid to the activities of the joints of the limbs, and the maintenance and training of muscle strength, so as to reduce the atrophy and weakness of the limb muscles caused by bed rest. Lower limb muscle elevation and pulling training can be carried out at an early stage to help prevent nerve root adhesion and scar formation. After lumbar internal fixation, when the patient can get out of bed during the period of bed rest, he must first wear a waist cuff and other protective gear, and still need to wear a waist cuff within two weeks after getting out of bed, avoiding prolonged standing or sitting, as well as heavy physical labor. In summary, one month after the lumbar spine fracture internal fixation surgery is not recommended to walk with weight, such as walking with a large weight dumbbell straight back, so as not to cause secondary injury to the lumbar spine. Patients need to carry out rehabilitation exercises under the guidance of the doctor, so as not to cause damage to the organism due to improper operation.
