Irreparable Rotator Cuff Tear

Introduction: Reverse shoulder replacement (RSR) has been accepted as the treatment of choice for glenohumeral arthritis with irreparable rotator cuff tear. Dislocation has been a potential complication of RSR but glenosphere disengagement is a rare complication itself. There have been only few published reports of this complication in the literature. Case Report: In this case report, we have presented a case of repeated disengagement of glenoid sphere post-RSR in a 72-year-old male retired army personnel operated with Zimmer Biomet comprehensive RSR design. Conclusion: In our case scenario, we postulate that soft-tissue interposition was the reason for disengagement during first episode and was successfully relocated after removal. However, the subsequent disengagement was due to improper seating of sphere due to large central screw. Revision to a smaller central screw size appears to be the definitive solution in such case. Keywords: Reverse shoulder replacement, glenosphere disengagement, glenohumeral arthritis, irreparable rotator cuff tear.

AbstractThe assessment of rotator cuff tear prior to shoulder replacement is based on the physical findings and imaging procedures, preferably magnetic resonance imaging (MRI). However, MRI is not always available, and in trauma patients, the CT-scan-based classification of glenohumeral arthritis or tendon damage is generally not applicable. In case of 4-part dislocated proximal humerus fractures the right diagnosis is crucial prior to choose between different type protheses or osteosyntheses. Therefore, there is a need for novel methods for the evaluation of rotator cuff damage. Our aim was to evaluate whether differential scanning calorimetry (DSC) could determine the grade of rotator cuff damage in patients undergoing shoulder replacement. Small samples of rotator cuff tendons of patients undergoing reversed shoulder replacement due to orthopedic or trauma indications were resected during surgery, and thermal parameters were measured using DSC. Radiological evaluation was also performed to classify the degree of rotator cuff damage and glenohumeral arthritis. In case of orthopedic samples, the consequence of advanced tendon damage was well demonstrated by the shape and the running of the curves, compared to the control sample. In trauma samples, the moderately degenerated tendons also exhibited significant difference from the control in the shape of the scans and in the thermal parameters. DSC curves demonstrated a clear difference in the thermal parameters of healthy and pathologic samples. DSC could be a useful additional method in the evaluation of rotator cuff tear arthropathies in future studies.
