RT Journal A1 Dürr, H R A1 Stäbler, A A1 Müller, P E A1 Refior, H J T1 Thorn-Induced Pseudotumor of the Metatarsal A Case Report JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 2001 FD April 1 VO 83 IS 4 SP 580 OP 580 DO UL http://dx.doi.org/ AB Penetrating wounds of the foot are not uncommon. Many are caused by thorns or by fragments of wood that are retained in the foot, creating a foreign-body granuloma1. Symptomatic lesions may develop years after the injury, and the patient may not remember a specific injury event2. While chronic foreign-body reactions in soft tissues are quite common, penetrating injuries to the bone are rare3,4. Here we report the case of a thorn-induced osteolytic pseudotumor of the fifth metatarsal and review the findings concerning thirty-one other thorn or wood-induced bone lesions reported in the literature.
