Comorbidities associated with cervical spine degenerative disc disease

Area of Science:

• Orthopedics
• Gerontology
• Epidemiology

Background:

• Degenerative disc disease (DDD) of the cervical spine is a common condition.
• Understanding the factors contributing to cervical spine DDD progression is crucial for effective management.
• Medical comorbidities may play a significant role in the pathomechanisms of disc degeneration.

Purpose of the Study:

• To identify associations between various medical comorbidities and the severity of cervical spine DDD.
• To elucidate the influence of aging and comorbidities on the progression of cervical spine DDD.

Main Methods:

• Retrospective review of electronic medical records and magnetic resonance imaging data.
• Evaluation of 799 patients assessed for cervical spine pathology.
• Bivariate analysis to determine associations between patient characteristics and DDD grade.

Main Results:

• Older age, diabetes, hypertension, smoking, and a history of previous cervical spine surgery were strongly associated with increased cervical spine DDD severity.
• Other identified comorbidities included cancer, COPD, depression, hypothyroidism, peripheral vascular disease, and Medicare status.
• Lower median household income was also associated with increased DDD severity.

Conclusions:

• Aging and the accumulation of medical comorbidities are significant factors influencing the severity of cervical spine DDD.
• These findings suggest a multifactorial etiology for cervical spine DDD, involving both aging and systemic health conditions.
