Active extension deficit (AED) for the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints 5 weeks and 2 years after collagenase injection for Dupuytren's contracture in 50 treated fingers. The joints shown in this diagram are those with AED of at least 10° at 5 weeks or in which AED had changed between the 5-week and the 2-year measurements; AED measured with 5° intervals and joints with identical values juxtaposed for visual clarity. For example, the ♦ farthest to the right on the x-axis represents a treated finger in which MCP AED was 0° at 5 weeks and 65° at 2 years, and the □ in the upper right corner of the graph represent a treated finger in which PIP AED was 55° at 5 weeks and 75° at 2 years. In four joints a second injection after the 5-week measurement was given. Joints without contracture (AED 0–5°) at the 5-week and the 2-year measurement (27 MCP and 23 PIP joints) are not shown in the diagram.
