We have analysed 249 consecutive fractures of the humeral shaft treated over a three-year period. The fractures were defined by their AO morphology, position, the age and gender of the patient and the mechanism of injury. Open fractures were classified using the Gustilo system and soft-tissue injury, and closed fractures using the Tscherne system. The fractures were classified as AO type A in 63.3%, type B in 26.2% and type C in 10.4%. Most (60%) occurred in the middle third of the diaphysis with 30% in the proximal and 10% in the distal third. The severity of the fracture and soft-tissue injury was greater with increasing injury severity. Less than 10% of the fractures were open. There was a bimodal age distribution with a peak in the third decade as a result of moderate to severe injury in men and a larger peak in the seventh decade after a simple fall in women.
我们分析了在三年期间治疗的249例肱骨干连续性骨折。这些骨折根据其AO形态、位置、患者年龄和性别以及损伤机制进行定义。开放性骨折采用Gustilo系统进行分类并评估软组织损伤情况，闭合性骨折则采用Tscherne系统进行分类。骨折分类为AO A型的占63.3%，B型占26.2%，C型占10.4%。大多数（60%）发生在骨干的中三分之一段，30%发生在近端，10%发生在远端三分之一段。随着损伤严重程度的增加，骨折和软组织损伤的严重程度也更高。开放性骨折不到10%。年龄分布呈双峰状，第三个十年出现一个峰值，这是由于男性受到中度至重度损伤所致，而在第七个十年出现一个更大的峰值，这是女性因简单跌倒所致。
