Figure 1
Magnetic resonance arthrography of the right shoulder. T2-weighted fat-suppressed oblique coronal sequence (A) and T1-weighted fat-suppressed sagittal sequence (B) illustrate a complete second rerupture of the supraspinatus and infraspinatus tendons.
Figure 2
Figure 2
Arthroscopic view from the lateral portal showing a “shattered-glass” appearance of the subacromial space completely obliterated by numerous fragmented remnants of the InSpace balloon.
Figure 3
Figure 3
Macroscopic appearance of the extracted ruptured InSpace balloon fragments.
Figure 4
Figure 4
Arthroscopic visualization from the lateral portal highlighting the balloon's valve as a freely floating structure within the subacromial space.
Figure 5
Figure 5
Condition of the posterosuperior rotator cuff tendons after extensive subacromial débridement of balloon fragments.
Figure 6
Figure 6
High-magnification histological view showing focal presence of neutrophilic granulocytes (highlighted in red circles) within the stromal tissue.
