Pieter De Rudder: Eight-Year Open Leg Fracture Healed Instantly

On February 16, 1867, Belgian farm laborer Pieter De Rudder's left leg was crushed by a falling tree, fracturing both tibia and fibula in a compound break. Despite medical treatment over eight years — with one surgeon recommending amputation — the fracture never knit; an open wound remained and the leg bones moved independently.

On April 7, 1875, De Rudder visited a replica Lourdes shrine in Oostakker, Belgium. Within hours he was reportedly walking normally, the wound closed and the bones apparently solid. Local physicians documented the recovery. The story circulated widely as the most scientifically documented Lourdes miracle, eventually reaching the Lourdes Medical Bureau, which declared it miraculous in a retrospective review.

The critical problem came in 1899 when De Rudder died and his body was exhumed. Investigators found the leg bones showed malunion — not the seamless regeneration the account required. Skeptic Joe Nickell concluded the fracture had healed before the shrine visit and was presented as instantaneous after the fact. The 18-year gap before formal testimony was recorded is a serious evidential problem by any standard.

This case is the most famous and the most problematic. The post-mortem physical evidence directly contradicts the central miracle claim. It should be treated with low confidence despite its prominence in Lourdes literature.
