Is surgery the only option for spondylosis?

No! Spondylosis is degeneration of the spine. It is also called spine arthritits. It normally occurs to some extent in everyone, depending on genes, lifestyle (exercise, occupation, recreation, smoking). Almost everyone living to 65 years or more will have some degree of spondylosis. It may not cause any symptoms such as pain. A healthy lifestyle with regular exercise often is enough for many folks.
No. Most patients with spondylosis respond to conservative management, such as physical therapy, medications, and home exercise programs. In appropriate patients with more severe pathology, procedures such as epidurals, nerve blocks, and facet blocks/rhizotomies may lessen symptoms. Surgery is a last option for cases with poor response to non-operative methods.
