 Back.com - FAQs - When is surgery necessary for patients with spine problems?
Surgery is necessary when all the conservative treatments have been ineffective and the symptoms persist or when there is a significant neurologic impairment such as profound weakness resulting in a foot drop or when there is bowel or bladder dysfunction.
Other situations where surgery is necessary include instability of the spine where the structure of the spine is unstable and surgery is necessary to protect the nerves.
Besides these rare and urgent situations, surgery is typically necessary for patients who have failed conservative treatment and are still having significant symptoms, which inhibit their lifestyle.
