Abstract

Reaming products taken during intramedullary nailing were examined to identify possible differences in their composition depending on the reaming percentage. Reaming products were taken from 39 fresh closed tibial and femoral diaphyseal fractures in patients with an average age of 29 years. According to histology, reaming products mainly consisted of bone trabeculae, viable or nonviable, and bone marrow stroma. A statistically significant reverse correlation exists between viable bone mass percentage and reaming progress. Reaming 1 mm less than the minimum canal diameter provides a higher viable bone mass percentage, which might be an important factor in the bone healing process.

摘要

对髓内钉固定过程中获取的扩髓产物进行检查，以确定其成分是否因扩髓百分比不同而存在差异。扩髓产物取自39例新鲜闭合性胫骨干和股骨干骨折患者，患者平均年龄29岁。根据组织学检查，扩髓产物主要由骨小梁（存活或不存活）和骨髓基质组成。存活骨量百分比与扩髓进程之间存在统计学上显著的负相关。扩髓比最小髓腔直径少1毫米时，存活骨量百分比更高，这可能是骨愈合过程中的一个重要因素。
