Characteristics of the two samples of patients with Dupuytren's contracture treated with CCH injection or surgery (fasciectomy)
| CCH injection | Fasciectomy | |
|---|---|---|
| Number of patients (men) | 16 (11) | 16 (13) |
| Age (years), mean (SD) | 69 (4) | 71 (5) |
| Number of fingers treated* | ||
| Small | 11 | 9 |
| Ring | 7 | 8 |
| Middle | 0 | 1 |
| Extension deficit (degrees) | ||
| Total† | ||
| Mean (SD) | 90 (39) | 71 (28) |
| Median (IQR) | 70 (60–115) | 75 (45–89) |
| MCP‡ | ||
| Mean (SD) | 64 (16) | 60 (17) |
| Median (IQR) | 65 (60–75) | 60 (41–80) |
| PIP‡ | ||
| Mean (SD) | 55 (22) | 46 (18) |
| Median (IQR) | 55 (43–70) | 40 (35–48) |
*Two patients in each group had two fingers treated.
†MCP plus PIP joints in all treated fingers (in patients with 2 fingers treated the finger with largest extension deficit was used).
‡The values showing MCP and PIP extension deficits separately include only joints with contracture (no MCP contracture in 1 patient in the CCH group and 2 patients in the fasciectomy group and no PIP contracture in 7 patients in each group).
CCH, collagenase Clostridium histolyticum; MCP, metacarpophalangeal; PIP, proximal interphalangeal.
