no fracture present
analgesia
Acetaminophen and/or a nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen or naproxen is recommended for the medical management of pain in axial disease. Topical NSAIDs may be trialed in patients with peripheral joint disease.
NSAIDs should be used with caution in older people because of increased susceptibility to adverse effects such as gastrointestinal bleeding and cardiovascular events.[61]McCarberg BH. NSAIDs in the older patient: balancing benefits and harms. Pain Med. 2013 Dec;14 Suppl 1:S43-4. https://academic.oup.com/painmedicine/article/14/suppl_1/S43/1941495 http://www.ncbi.nlm.nih.gov/pubmed/24373111?tool=bestpractice.com [62]Davis A, Robson J. The dangers of NSAIDs: look both ways. Br J Gen Pract. 2016 Apr;66(645):172-3. https://bjgp.org/content/66/645/172 http://www.ncbi.nlm.nih.gov/pubmed/27033477?tool=bestpractice.com Use the lowest effective dose for the shortest effective treatment duration.
Application of heat may also be effective in providing temporary relief of pain symptoms.[59]Mader R. Current therapeutic options in the management of diffuse idiopathic skeletal hyperostosis. Expert Opin Pharmacother. 2005 Jul;6(8):1313-8. http://www.ncbi.nlm.nih.gov/pubmed/16013982?tool=bestpractice.com
Consider referral to a specialist in pain management if pain symptoms are not adequately controlled by simple analgesia.
Primary options
acetaminophen: 325-1000 mg orally every 4-6 hours when required, maximum 4000 mg/day
-- AND / OR --
ibuprofen: 400 mg orally every 4-6 hours when required, maximum 3200 mg/day
or
naproxen: 250-500 mg orally twice daily when required, maximum 1250 mg/day
OR
diclofenac topical: (1% gel) upper extremity joints: apply 2 g to the affected joint(s) four times daily, maximum 8 g/joint/day or 32 g/day total; lower extremity joints: apply 4 g to the affected joint(s) four times daily, maximum 16 g/joint/day or 32 g/day total
physical therapy and patient education
Treatment recommended for ALL patients in selected patient group
Nonpharmacologic approaches include patient education (with particular emphasis on joint protection and fracture prevention) and exercise/physical therapy.
Literature on the use of exercise/physical therapy in patients with DISH is sparse. One study on the effect of a 24-week exercise program consisting of mobility, stretching, and strengthening exercises for the cervical, thoracic, and lumbar spine reported small improvements in physical measures, which achieved significance only for lumbosacral flexion.[60]Al-Herz A, Snip JP, Clark B, et al. Exercise therapy for patients with diffuse idiopathic skeletal hyperostosis. Clin Rheumatol. 2008 Feb;27(2):207-10. http://www.ncbi.nlm.nih.gov/pubmed/17885726?tool=bestpractice.com
Orthotic insoles may also be considered as an option to improve posture.
surgical decompression
Treatment recommended for SOME patients in selected patient group
Specialist input for consideration of surgical decompression is recommended for progressive neurologic symptoms, such as spinal stenosis, myelopathy, or radiculopathy.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com Robust literature on the management of neurologic symptoms in patients with DISH is lacking.
dietary changes and swallowing therapy
Treatment recommended for SOME patients in selected patient group
For patients with dysphagia or airway issues, a multidisciplinary approach, including otolaryngologists and speech therapists, is recommended.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
If the dysphagia is mild, manage conservatively with dietary changes (modifying texture to soft, pureed foods), swallowing therapy, and medical management.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
surgical resection of anterior cervical osteophytes
Treatment recommended for SOME patients in selected patient group
If there is airway impairment and/or severe dysphagia, obtain urgent orthopedic input for consideration of surgical osteophyte removal.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com [63]Castellano DM, Sinacori JT, Karakla DW.

For surgical resection of anterior cervical osteophytes, transoral, posterolateral, and anterior cervical osteophyte exposures have been used. However, the left anterolateral technique is frequently employed because it is convenient for spinal surgeons and may reduce the risk of injury to the recurrent laryngeal nerve.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com The anterolateral approach is particularly preferred given the ease of osteophyte removal and extended approach from C2-T1.[64]Harlianto NI, Kuperus JS, Verlaan JJ. Perioperative management, operative techniques, and pitfalls in the surgical treatment of patients with diffuse idiopathic skeletal hyperostosis: a narrative review. Explor Musculoskeletal Dis. 2023;1:84-96. https://www.explorationpub.com/Journals/emd/Article/100713
Risks associated with surgery are usually related to frailty of patients and/or distorted anatomy.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
fracture present
orthopedic referral and consideration for surgery
Patients with DISH are at increased risk of vertebral body fractures. DISH increases the risk of unstable spine fractures, which can result from low-energy mechanisms such as ground-level falls, tenfold.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com [65]Reinhold M, Knop C, Kneitz C, et al. Spine fractures in ankylosing diseases: recommendations of the spine section of the German Society for Orthopaedics and Trauma (DGOU). Global Spine J. 2018 Sep;8(2 suppl):56-68S. https://journals.sagepub.com/doi/10.1177/2192568217736268 http://www.ncbi.nlm.nih.gov/pubmed/30210963?tool=bestpractice.com The most frequent fractures seen in individuals with DISH are hyperextension fractures through fused vertebral bodies; the most commonly affected segments of the spine are the cervical, thoracic, and lumbar, in that order.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
Seek orthopedic assessment for patients with spinal fracture associated with DISH as these patients are typically managed with surgery. Nonsurgical management of vertebral body fracture associated with DISH is typically reserved for individuals without neurologic compromise who have medical conditions that make surgery unsuitable, because immobilization with an orthosis alone is linked to problems such as fracture displacement with consequent neurologic dysfunction and increasing deformity.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com Patients with DISH frequently have fixed kyphotic deformities, making the bracing treatment of thoracolumbar fractures challenging.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com Compared with nonsurgical management, surgery is linked to lower mortality rates.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
If surgery is indicated, important factors to consider when choosing a technique include the patient's comorbidities, the presence of neurologic deficits, any preexisting deformities, and the requirement for fracture reduction.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com Surgical techniques typically used in patients suitable for surgery are open pedicle screw fixation and percutaneous pedicle screw (if no neurologic deficit is present). Studies show that, compared with open fixation, percutaneous stabilization results in reduced blood loss, shorter operating times, fewer transfusion requirements, and lower perioperative complication rates.[64]Harlianto NI, Kuperus JS, Verlaan JJ. Perioperative management, operative techniques, and pitfalls in the surgical treatment of patients with diffuse idiopathic skeletal hyperostosis: a narrative review. Explor Musculoskeletal Dis. 2023;1:84-96. https://www.explorationpub.com/Journals/emd/Article/100713
Corrective osteotomies are rarely advised as part of the surgical management of spinal fractures, even in the presence of significant baseline kyphotic abnormalities.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com These procedures may increase spinal instability or increase the likelihood of pseudoarthrosis and implant failure.[1]Le HV, Wick JB, Van BW, et al.

J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com
Management options in patients without neurologic compromise who are unsuitable for surgical intervention include immobilization, use of a cervical collar (c-collar), halo, and analgesia.[1]Le HV, Wick JB, Van BW, et al. Diffuse idiopathic skeletal hyperostosis of the spine: pathophysiology, diagnosis, and management. J Am Acad Orthop Surg. 2021 Dec 15;29(24):1044-51. http://www.ncbi.nlm.nih.gov/pubmed/34559699?tool=bestpractice.com [66]Taher AW, Page PS, Greeneway GP, et al.

analgesia
Treatment recommended for ALL patients in selected patient group
Analgesia should begin with nonopioid drugs such as acetaminophen and a nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen or naproxen. Data from animal studies on the impairment of fracture healing by NSAIDs are inconclusive, and these agents are regularly used clinically for this indication.[67]Borgeat A, Ofner C, Saporito A, et al. The effect of nonsteroidal anti-inflammatory drugs on bone healing in humans: a qualitative, systematic review. J Clin Anesth. 2018 Sep;49:92-100. http://www.ncbi.nlm.nih.gov/pubmed/29913395?tool=bestpractice.com [68]Marquez-Lara A, Hutchinson ID, Nuñez F Jr, et al.

JBJS Rev. 2016 Mar 15;4(3):e4. https://journals.lww.com/jbjsreviews/fulltext/2016/03000/nonsteroidal_anti_inflammatory_drugs_and.4.aspx http://www.ncbi.nlm.nih.gov/pubmed/27500434?tool=bestpractice.com NSAIDs should be used with caution in older people because of increased susceptibility to adverse effects such as gastrointestinal bleeding and cardiovascular events.[61]McCarberg BH. NSAIDs in the older patient: balancing benefits and harms. Pain Med. 2013 Dec;14 Suppl 1:S43-4. https://academic.oup.com/painmedicine/article/14/suppl_1/S43/1941495 http://www.ncbi.nlm.nih.gov/pubmed/24373111?tool=bestpractice.com [62]Davis A, Robson J.

If stronger analgesia is required, opioids (e.g., oxycodone) can be used in combination with acetaminophen. If opioids are used, a laxative should also be prescribed and fluid intake encouraged to prevent constipation. If used chronically, opioids may lose potency, induce dependence, raise risk for addiction, and lead to falls and central sensitization.[69]LeBoff MS, Greenspan SL, Insogna KL, et al. The clinician's guide to prevention and treatment of osteoporosis. Osteoporos Int. 2022 Oct;33(10):2049-102. https://link.springer.com/article/10.1007/s00198-021-05900-y http://www.ncbi.nlm.nih.gov/pubmed/35478046?tool=bestpractice.com Opioids are recommended only for very short-term use with acute fractures. Use the lowest effective dose for the shortest effective treatment duration.
For persistent severe pain, use of centrally-acting therapies including tricyclic antidepressants (e.g., amitriptyline) and gabapentin should be considered after discussion about the potential risks and benefits.
Amitriptyline should be used with caution in older patients, due to the risk of anticholinergic and sedating effects, and in patients with a history of cardiovascular disease.
Gabapentin should be used with caution in older patients due to the increased risk of respiratory depression and neurocognitive changes; start at the lowest dose and increase dose gradually while monitoring for symptoms. Also use with caution in patients with a history of substance misuse.

physical therapy and patient education
Treatment recommended for ALL patients in selected patient group
A period of immobilization or rest is recommended post fracture while the patient continues to be in acute pain. Physical therapy and exercise programs can be initiated when the degree of pain starts to diminish; prolonged immobilization is not recommended.
Literature on the use of exercise/physical therapy in patients with DISH is sparse. One study on the effect of a 24-week exercise program consisting of mobility, stretching, and strengthening exercises for the cervical, thoracic, and lumbar spine reported small improvements in physical measures, which achieved significance only for lumbosacral flexion.[60]Al-Herz A, Snip JP, Clark B, et al.
