v4.1 Fusion X
Zone I: tuberosity avulsion (pseudo-Jones) — usually heals conservatively. Zone II: Jones fracture at metaphyseal–diaphyseal junction — watershed area, higher nonunion → screw fixation esp. athletes. Zone III: proximal diaphyseal stress fracture — often needs surgery + graft in chronic cases.
