*3.5. Radiological Analysis*

At last FU, the mean humeral RLL score was 0.02 (range 0–1) for HA and 2.0 (range 0–6) for TSA (*p* = 0.002). In the HA group, there was no significant trend between glenoid bone wear and the pre-operative stage of Ficat and Cruess classification (*p* > 0.05). In the TSA group, the mean glenoid RLL score was 5.2 (range 0–18) with 2 migrated glenoid implants, considered as loosened but no revision surgery had been done (CS = 49 and 67). After 7 to 10 years postoperatively, glenoid loosening was observed in 6 patients who had not received revision surgery. There was no significant trend between glenoid loosening and the pre-operative stage of Ficat and Cruess classification (*p* > 0.05).

#### *3.6. Comparison between Different Hemi-Arthroplasties*

There were no significant differences between HA regarding postoperative complications, revision surgery and clinical outcomes (Table 3).
