[Hand injuries caused by self-made bombs. Observations and reconstructoin techniques. Report of 7 cases].
The authors report on their experience of sodium chlorate bomb injuries of the hand observed in seven boys. The thumb was damaged in all cases. This digit was amputated in five cases, was totally saved in one case and partially saved in another case. In four cases, the preservation of damaged tissues in the emergency procedure allowed a secondary reconstruction of the thumb, thus making it possible to achieve a prehensile and sensitive hand. In these former four cases, a posterior interosseous flap was performed to ensure the primary or secondary skin coverage. In two cases, the major lesions necessitated an amputation at the radiocarpal level. In one of these two cases, coverage of the amputated stump by a free gracilis muscle flap made it possible to minimize the level of amputation and to wear a functional prosthesis. Sodium chlorate bombs are made with an unstable chemical mixture. These reactives provoke high-energy injuries with a short range of dispersion. The damages depend on the prehensile mode, which explains why the thumb and the index finger are always injured. These blast injuries were limited to the hand and the skin coverage could be done with a distally based posterior interosseous flap. In spite of the impressive lesions observed in such young patients, a conservative attitude could be taken in an emergency situation with the aim to perform further reconstructive procedures.
