A lumbar disc herniation can lead to muscle atrophy, mainly neurogenic atrophy caused by the loss of innervation to the muscle. The normal function of skeletal muscles requires the nutrition and stimulation of nerves, and patients with lumbar disc herniation can experience atrophy due to compression of neurons, resulting in loss of innervation of the muscles. In addition, the patient’s reduced muscle activity caused by pain can also cause disuse atrophy. In general, this kind of muscle atrophy can be recovered, if the patient through convalescence, surgery and other methods to remove the lumbar intervertebral disc for the compression of the nerve root, restore the function of the nerve root, and at the same time through the appropriate activities, training of the affected side of the muscle, the atrophic muscles can be restored. If the patient has developed muscle atrophy, he should go to the hospital as soon as possible to avoid delaying his condition.
