Comorbidities in rotator cuff disease: a case-control study

Area of Science:

• Orthopedics
• Rheumatology
• Epidemiology

Background:

• Rotator cuff disease is prevalent but its risk factors are not well understood.
• This study investigates constitutional and environmental factors contributing to rotator cuff disease.

Purpose of the Study:

• To identify and quantify risk factors for rotator cuff disease.
• To assess the association between comorbidities and rotator cuff disease.

Main Methods:

• A large case-control study was conducted using The Health Improvement Network database.
• 5000 patients diagnosed with rotator cuff disease were matched with controls by age, sex, and primary care practice.

Main Results:

• Significant risk factors included Achilles tendinitis, trigger finger, lateral epicondylitis, and carpal tunnel syndrome.
• Oral corticosteroid use, oral antidiabetic use, insulin use, and overweight BMI (25.1-30) were also associated.
• Smoking, higher BMI (>30), alcohol intake, medial epicondylitis, and rheumatoid arthritis were not associated.

Conclusions:

• Several comorbidities and risk factors for rotator cuff disease were identified.
• These include lateral epicondylitis, carpal tunnel syndrome, trigger finger, Achilles tendinitis, oral corticosteroid use, and diabetes mellitus.
• Findings highlight the importance of recognizing comorbid conditions and guiding etiological research.
