Arthritis at the shoulder joint

Area of Science:

• Orthopedics
• Rheumatology
• Radiology

Background:

• The shoulder is a complex joint crucial for mobility and stability.
• Shoulder pain is a frequent clinical concern with diverse causes.
• Primary shoulder osteoarthritis is rare due to its non-weight-bearing nature.

Purpose of the Study:

• To review the pathogenesis of shoulder arthritis.
• To outline the clinical manifestations of glenohumeral joint arthritis.
• To highlight key imaging findings for common shoulder arthritis categories.

Main Methods:

• Literature review of shoulder arthritis.
• Analysis of clinical presentations.
• Correlation of imaging findings with diagnoses.

Main Results:

• Osteoarthritis of the glenohumeral joint is uncommon without trauma.
• Advanced degenerative changes in non-traumatic cases warrant further investigation for other disorders.
• Common categories of shoulder arthritis have distinct clinical and imaging features.

Conclusions:

• Understanding the varied causes of shoulder arthritis is crucial for accurate diagnosis.
• Imaging plays a key role in identifying and characterizing glenohumeral joint arthritis.
• Clinicians should consider differential diagnoses for osteoarthritis in the absence of trauma.
