From 1989 to 1991, eighteen cases of the metacarpal bony loss from war injury were treated in Africa. Their ages ranged from 17～56 years old. Fourteen patients were injuried from gunshot; another four were injuried from blast. All of the eighteen were performed with W shape wire, and these can be done as early as 4～16 hours after the initial injuries. The author introduced the way of making W wire and the important points of the surgical technics. We suggest that the key to the successful operation is the good debridement,covertage of wound with healthy soft tissue and the good drainage.
