Presentation
Pain in shoulder with restriction of movements
Patient Data
Lateral downsloping, type II acromion with acromioclavicular joint arthropathy, subchondral erosions, marrow oedema and eburnation along articular margins. This is causing reduced subacromial space.
Significant supraspinatus tendinosis is seen with full thickness tear of anterior, mid fibres, at footprint, measuring approx. 16mm in transverse and 15mm in anteroposterior dimensions.
Infraspinatus tendinosis is also seen with partial thickness articular surface tear of mid fibres at insertion site involving approx. 10-20% thickness. The tear measures approx. 4mm in transverse and 8mm in anteroposterior dimensions.
No significant retraction of torn fibres is seen.
No obvious reduced bulk / fatty atrophy of rotator cuff muscles seen.
Significant degeneration of glenoid labrum is seen with SLAP tear approx. 10 to 1 O’clock positions. Tendinosis of intracapsular segment of biceps tendon is seen.
Reduced glenohumeral joint space is seen with partial thinning / loss of articular cartilage, marginal osteophytes and subchondral cystic changes in superior glenoid. Few small cysts are also seen in posterolateral aspects of head of humerus. Subcoracoid, subacromial - subdeltoid bursitis is seen with areas of synovial thickening. Soft tissue in rotator cuff interval with thickening of the capsule.
Case Discussion
Significant supraspinatus tendinosis with full thickness tear of anterior, mid fibres, at footprint.
Infraspinatus tendinosis with partial thickness articular surface tear of mid fibres at insertion site.
No significant retraction of torn fibres or reduced bulk / fatty atrophy of rotator cuff muscles seen.
