For patients with more persistent symptoms or those who do not respond adequately to NSAIDs, DMARDs such as methotrexate or sulfasalazine may be considered. These medications can help slow disease progression and reduce inflammation over time[2].

Biologic Agents

In cases where traditional treatments are ineffective, biologic agents like tumor necrosis factor (TNF) inhibitors (e.g., etanercept, infliximab) or interleukin inhibitors (e.g., secukinumab) may be prescribed. These medications target specific pathways in the inflammatory process and can provide significant relief for patients with severe inflammatory spondylopathies[3].

Corticosteroids

Corticosteroids may be used for short-term management of acute inflammation. They can be administered orally or through injections directly into the affected area to provide rapid relief from severe symptoms[4].

Non-Pharmacological Treatments

Physical Therapy

Physical therapy plays a crucial role in managing inflammatory spondylopathies. A tailored exercise program can help improve flexibility, strengthen neck muscles, and enhance overall function. Physical therapists may also employ techniques such as manual therapy and modalities like heat or cold therapy to alleviate pain[5].

Chiropractic Care

Chiropractic adjustments may provide relief for some patients, particularly those experiencing mechanical pain associated with inflammation. However, it is essential to consult with a healthcare provider before starting chiropractic treatment, especially in cases of significant inflammation or instability in the cervical spine[6].

Lifestyle Modifications

Encouraging patients to adopt a healthy lifestyle can also be beneficial. This includes maintaining a balanced diet rich in anti-inflammatory foods, engaging in regular low-impact exercise, and practicing stress-reduction techniques such as yoga or meditation[7].

Surgical Interventions

In rare cases where conservative treatments fail and significant structural issues arise, surgical options may be considered. Procedures could include decompression surgery or spinal fusion, particularly if there is evidence of instability or severe nerve compression[8].
