治疗四肢骨折作外固定的器材种类很多。在长江以南大都运用杉皮夹板。这种方法虽然有悠久的历史,但对杉树皮及杉皮夹板作外固定的有关问题,如肢体体型、约束力等等,在理论上极少有报导,为了提高杉皮夹板对四肢骨折的固定作用,因此,初步分六个专题进行研究,现将其内容择要摘述如 There are many types of equipment for the treatment of limb fractures for external fixation. Most of the south of the Yangtze River use spruce plywood. Although this method has a long history, issues related to the external fixation of pine bark and fir bark, such as body shape, binding force, etc., have rarely been reported in theory, in order to improve the fir bark splint to limb fractures. As a result of the fixed role, the study is initially divided into six topics, and its contents are summarized as follows:
