Humerus fractures comprise 5% to 8% of all fractures. Although uncommon, nonunions can present a frustrating challenge to the orthopedic surgeon. Various risk factors that may predispose patients to nonunion include obesity, osteoporosis, alcoholism, smoking, poor bone quality, and scar tissue. Many methods of treatment have been described with various degrees of success. The rates of healing of humeral nonunions by traditional means of internal fixation with bone graft range from 70% to 92%, although in cases of infection, poorly vascularized beds, and open, segmental, or severely comminuted fractures, secondary bony healing may still be compromised.
肱骨骨折占所有骨折的5%至8%。尽管不常见，但骨不连会给骨科医生带来令人沮丧的挑战。可能使患者易发生骨不连的各种风险因素包括肥胖、骨质疏松、酗酒、吸烟、骨质质量差和瘢痕组织。已经描述了许多治疗方法，且取得了不同程度的成功。采用传统骨移植内固定方法治疗肱骨骨不连的愈合率在70%至92%之间，不过在感染、血运不佳的创面以及开放性、节段性或严重粉碎性骨折的情况下，二期骨愈合仍可能受到影响。
