Pooled estimates of CRPS, deltoid injury, hematoma, and heterotopic ossification following RSA
| Studies included | Shoulders | Incidence | Current study rate, % (n/n) | Zumstein et al rate, % (n/n) | P value current study vs. Zumstein et al | |
|---|---|---|---|---|---|---|
| CRPS | 74 | 5529 | 23 | 0.4 (23/5529) | 0.5 (4/782) | .77∗ |
| Deltoid injury | 74 | 5529 | 5 | 0.1 (5/5529) | — | — |
| Hematoma | 74 | 5529 | 15 | 0.3 (15/5529) | 2.6 (20/782) | <.001∗ |
| Heterotopic ossification | 74 | 5529 | 46 | 0.8 (46/5529) | 0.8 (6/782) | .86 |
CRPS, complex regional pain syndrome; RSA, reverse shoulder arthroplasty; JSES, Journal of Shoulder and Elbow Surgery.
Hematoma rates have significantly decreased compared with Zumstein et al (JSES, 2011).
