Schematic view of reintegration. (A) After stylopod amputation, the elbow joint is regenerated as a miniature of the intact elbow joint, such that the normal ratio between √S _j and $\sqrt[3]{V}$ of the radius is maintained, suggesting that the joint might be regenerated in a manner similar to the developmental and postnatal processes. (B) After joint amputation, the regenerated cartilage is thick around the elbow joint, suggesting that this regeneration occurs via mechanisms that depend on the size of the remaining humerus.
