Summary
Frozen shoulder, a condition involving glenohumeral joint capsule retraction, can present with unique symptoms. This study explores a distinct pathological process causing shoulder stiffness not identified by standard imaging.
Area of Science:
- Orthopedics
- Sports Medicine
- Rheumatology
Background:
- Frozen shoulder (adhesive capsulitis) is characterized by glenohumeral joint capsule retraction.
- Arthrography aids in differentiating frozen shoulder from other causes of shoulder stiffness when clinical findings are unclear.
Observation:
- Three cases of shoulder stiffness with restricted flexion (120 degrees) and a sensation of mechanical blockage were observed.
- Painful restricted medial rotation contrasted with normal lateral rotation.
- Standard imaging (arthrography, MRI) showed no capsulitis or rotator cuff tears.
Findings:
- A unique pathological process causing shoulder stiffness was identified.
- Potential causes include proximal long head of biceps brachii lesion or focal ligamentous lesion.
- This condition differs from typical frozen shoulder and other stiff shoulder pathologies.
Implications:
- Highlights a distinct shoulder stiffness etiology requiring specific diagnostic consideration.
- Suggests targeted physical therapy and, if necessary, gentle manipulation under anesthesia for refractory cases.
- Emphasizes the importance of considering less common pathologies when imaging is inconclusive.
