The condition shown in the picture above represents Grade 3 severity stage of Dupuytren disease.
Dupuytren disease is a fibrosing disorder that results in slowly progressive thickening and shorting of the palmar fascia and leads to debilitating digital contractures, particularly of the metacarpophalangeal (MCP) joints or the proximal interphalangeal (PIP) joints. This condition usually affects the fourth and fifth digits (the ring and small fingers).
Grades of severity
The grading system for Dupuytren disease severity is as follows :
- Grade 1 – Thickened nodule and band in the palmar aponeurosis; may have associated skin abnormalities
- Grade 2 – Development of pretendinous and digital cords with limitation of finger extension
- Grade 3 – Presence of flexion contracture.
