Results of reverse arthroplasty in patients with rheumatoid arthritis (N = 23, except for pain, N = 27) expressed as mean values ± SD (range)*
| Variable | Preoperative | Postoperative | p Value |
|---|---|---|---|
| Pain (Visual Analog Scale) | 8.0 ± 2.4 (4.9–10) | 1.0 ± 2.1 (0–9) | < 0.001 |
| Flexion | 33° ± 29° (0°–110°) | 115° ± 32° (0°–160°) | < 0.001 |
| Abduction | 26° ± 23° (0°–80°) | 103° ± 37° (20°–180°) | < 0.001 |
| External rotation | 0.6 ± 1.2 | 5.8 ± 3.4 | < 0.001 |
| Internal rotation | 2.1 ± 2.2 | 2.9 ± 2.4 | NS |
| Constant score | 13 ± 8.1 (2–34) | 52 ± 15 (15–77) | < 0.001 |
* Functional rotation assessed according to points in Constant-Murley score (maximum 10 points) and expressed as mean value ± SD; NS = nonsignificant.
