Survival of humeral head autograft for glenoid bone loss in reverse total shoulder arthroplasty: a case report of long-term follow-up post ground level fall

Figures

• 

  Figure 1. Preoperative X-rays showing end-stage glenohumeral arthritis with posterior subluxation of the humeral head. The amount of subluxation is suspicious for glenoid hypoplasia.

• 

  Figure 2. MRI of the left shoulder showing severe tendinosis of the supraspinatus. MRI, magnetic resonance imaging.

• 

  Figure 3. MRI of the left shoulder showing posterior labral hypertrophy (arrow) characteristic in glenoid hypoplasia. MRI, magnetic resonance imaging.

• 

  Figure 4. Preoperative axial CT images demonstrating the severity of posterior glenoid bone loss and glenoid retroversion. CT, computed tomography.

• 

  Figure 5. CT scan demonstrating a characteristic dentate lesion of the glenoid in glenoid hypoplasia. CT, computed tomography.

• 

  Figure 6. Preoperative templating demonstrating the remaining void after baseplate positioning. Only 40% of baseplate is in contact with bone. Glenoid retroversion was measured at 50°.

  Figure 7. Two-week postoperative anterior-posterior and axillary views of the left shoulder showing humeral head autograft (left) and appropriate glenohumeral alignment (right).

  Figure 8. Preoperative CT of patient’s periprosthetic humerus fracture 4 years after index surgery before ORIF. CT, computed tomography; ORIF, open reduction and internal fixation.

• 

  Figure 9. Axial CT images showing complete incorporation of humeral head autograft 4 years after index operation. No fractures, lucencies or migration present despite traumatic event. CT, computed tomography.
