Nissen-Lie classification

Nissen-Lie classification is a system of categorizing Colles' fractures. In the Nissen-Lie classification system, there are seven types of fractures.^[1] The classification system was first published in 1939.

Classification

• Type 1: A fracture at the junction of the shaft and distal extremity of the radius (occurs only in children between the age of 1 and 15 years, and is most commonly a greenstick fracture)
• Type 2: Slipping of the epiphysis with dorsal displacement, often with a dorsally avulsed triangular fragment of the radius (occurs in the age range 10-20 years)
• Type 3: Minimal displacement
• Type 4: Dorsal angulation, extra-articular, no comminution
• Type 5: Intra-articular, comminuted
• Type 6: Fractures of the radial styloid
• Type 7: Fractures with dorsal displacement
