Traumatic allogenic bone implantation is becoming increasingly common in the setting of road trauma and suicide bombings. We present a unique case where a large bony fragment from one individual became embedded in the arm of another person following a "head-on" collision involving two motorbikes. Several management issues are outlined.

A 14-year-old girl presented with a painful right foot. She was an elite water-polo player and could recall no history of specific trauma to the foot. On close and persistent questioning, she admitted to having taken up playing the drums recently, with practice sessions of up to 4 h/d. She used the foot drum with her right foot and had noticed that this was becoming increasingly painful and prevented her playing the instrument for the last 2 days. Plain films of the foot were originally reported as normal, but revised to abnormal after the scintigraphic study. Bone scintigraphy confirmed a stress fracture of the right 3rd metatarsal bone. Stress fractures of the 3rd metatarsal bone are rare with only 2 previous reports in the literature.
