Abstract

Purpose: The recovery of a bone fracture is a process that is not yet fully understood. The literature conflicts on the results obtained by the interposition of foreign tissue inside a damaged bone. The objective of the present study was to ascertain the effect of placing muscle tissue between the stumps of a fractured bone.

Method: The study was carried out on 10 rabbits divided into 2 groups (n = 5): Group 1--partial fracture of the humerus and interposition of muscle tissue; Group 2--complete fracture of the humerus and interposition of muscle tissue. The fractured limb of all animals was immobilized for 8 weeks. At the end of this time, the rabbits were killed and their operated humeri were carefully removed for roentgenological and histological assessment.

Results: All humeri of Group 1 recovered their integrity and normal aspect. However, the healing of the humeri of Group 2 was not perfect. Gross angulation of the bone diaphysis occurred in all animals, and immature trabecular bone, osteochondral tissue, and persistence of muscle tissue substituted normal bone.

Conclusions: Interposed muscle does not affect partial bone fracture healing but causes instability in a complete fracture.

肌肉组织在骨愈合部位的作用。

目的:骨折的恢复是一个尚未完全了解的过程。在受损骨内插入外来组织所获得的结果与文献相矛盾。本研究的目的是确定在骨折残端之间放置肌肉组织的效果。方法:将10只家兔分为2组(n = 5): 1组——肱骨部分骨折及肌肉组织介入;第2组——肱骨完全骨折和肌肉组织间位。所有动物骨折肢体固定8周。在这段时间结束时，将家兔杀死，并仔细切除其手术肱骨进行x线和组织学评估。结果:1组肱骨全部恢复完整，外形正常。然而，第二组肱骨愈合不完全。所有动物的骨骨干都出现了明显的成角，未成熟的小梁骨、骨软骨组织和持续存在的肌肉组织取代了正常的骨。结论:置入肌肉不影响部分骨折愈合，但会导致完全骨折不稳定。
