Penetrating injury to radius or any other bone by fish bone is a rare kind of injury. Commonly metallic sharp objects, bullets, sharpnels, glass particles, hard wooden pieces are the causes of penetrating injury to bones. Radio-opaque objects are easy to detect and thus retrieval is relatively simpler than the radiolucent objects. Non-biological foreign bodies do not incite any reaction in the host bone whereas biological foreign bodies of either plant or animal origin cause hypersensitivity reaction. Osteitis along with excessive formation of new bones may be presented as a part of host reaction to the foreign body. We are presenting here an interesting case of a fisherman boy who sustained penetrating injury to radius by fish bone resulting in osteitis and a chronic non-healing sinus with watery discharge.
