Frequency of patients with inflammation in MCP, wrist or MTP joints at physical examination and MRI
| MCP joints (%) | Wrists (%) | MTP joints (%) | |
|---|---|---|---|
| Physical examination | |||
| ≥1 swollen joint | 36 | 30 | 25 |
| ≥1 tender joint | 40 | 11 | 41 |
| MRI | |||
| Synovitis score ≥1 | 26 | 60 | 7 |
| Tenosynovitis score ≥1 | 21 | 52 | n.a. |
| Bone marrow oedema score ≥1 | 17 | 58 | 12 |
The frequencies at physical examination represent the frequencies of patients with at least one swollen or tender MCP, wrist or MTP joint.
The frequencies at MRI represent the frequencies of all MCP, wrist or MTP joints that had a synovitis, tenosynovitis or BME score of at least 1.
For technical reasons some joints on MRI could not be evaluated. Of all 716 MCP joints; 8 synovitis, 17 tenosynovitis and 14 BME scores were not assessed. Of all 179 wrists; 1 synovitis, 2 tenosynovitis and 6 BME scores were not assessed. Of all 895 MTP joints; 29 synovitis and 45 BME scores were not assessed.
