Summary
Ultrasonography effectively detects acromioclavicular joint (ACJ) pathologies, including degenerative changes and swelling, in patients with anterior shoulder pain. This imaging modality reveals issues missed by plain radiographs, aiding diagnosis and treatment.
Area of Science:
- Radiology
- Orthopedics
- Musculoskeletal Imaging
Background:
- Ultrasound is valuable for diagnosing acromioclavicular (AC) joint issues like trauma, inflammation, and degeneration.
- Anterior shoulder pain often involves the AC joint, necessitating accurate diagnostic tools.
Purpose of the Study:
- To document the sonographic features of AC joint pathology in individuals experiencing anterior shoulder pain.
- To compare ultrasound findings with plain radiographs in symptomatic patients.
Main Methods:
- Sonographic examination of the ACJ was performed on 30 adults with anterior shoulder pain.
- A control group of 30 asymptomatic individuals was also studied.
- Findings were correlated with plain radiographs of the symptomatic cohort.
Main Results:
- Sonographic findings included joint swelling, bone irregularities, ACJ space alterations, cysts, fluid collections, and calcifications, indicative of early osteoarthritis.
- One case of septic arthritis was identified, requiring aspiration and antibiotics.
- Ultrasound identified pathologies not visible on plain radiographs.
Conclusions:
- Ultrasonography is a crucial tool for evaluating anterior shoulder pain.
- Routine use of ultrasound can uncover various ACJ pathologies missed by plain radiography.
- Sonography aids in the comprehensive diagnosis of ACJ conditions.
