An Overview Of The Articular Classification System*

Juvenile (osseous immaturity)
Type I: Extra-articular coalition
A: No secondary arthritis
B: Secondary arthritis
Type II: Intra-articular coalition
A: No secondary arthritis
B: Secondary arthritis

Adult (osseous maturity)
Type I: Extra-articular coalition
A: No secondary arthritis
B: Secondary arthritis
Type II: Intra-articular coalition
A: No secondary arthritis
B: Secondary arthritis

* This classification of tarsal coalitions is based on age, articular involvement and secondary arthritic changes. The classification may be used as a foundation for the discussion of surgical management.
