We present an extremely rare case of traumatic dislocation of a sternal body segment in a child. We treated this sternal segment dislocation by means of open reduction using a newly developed pin made from poly-L-lactide containing 10 percent by weight hydroxyapatite. It is not necessary to remove this type of pin later because it is degradable and absorbed within the body within about one year after implantation. A two-year follow-up of this case revealed a good clinical result.
我们报告了一例儿童胸骨体节段创伤性脱位的极其罕见病例。我们使用一种新开发的由含10%（重量）羟基磷灰石的聚-L-丙交酯制成的钢针，通过切开复位的方法治疗了该胸骨节段脱位。由于这种类型的钢针是可降解的，植入后大约一年内可在体内吸收，因此之后无需取出。对该病例进行的两年随访显示临床效果良好。
