To assess humeral shaft nonunions after functional bracing and to identify any risk factors contributing to this outcome.
Seven men and 12 women were retrospectively studied that had been treated for at least three months in a functional brace and had developed a clinical and radiographic nonunion. Patients' charts and radiographs were reviewed to evaluate fracture patterns, mechanisms of injury, associated health problems, and associated injuries.
The results indicate a trend toward nonunion in patients with the following risk factors: obesity (37%); a history of cigarette smoking (53%); metabolic bone disease (32%); cardiovascular disease (37%); short oblique fractures (89%); open fractures (26%); and fractures of the proximal third of the diaphysis (68%). We recommend counseling these patients on the possible increased risk of nonunion from functional bracing and considering the option of operative fixation.
评估功能支具治疗后肱骨干骨不连情况，并确定导致该结果的任何风险因素。
对7名男性和12名女性进行回顾性研究，这些患者接受功能支具治疗至少三个月，且出现了临床和影像学骨不连。查阅患者病历和X线片，以评估骨折类型、损伤机制、相关健康问题和合并损伤。
结果表明，具有以下风险因素的患者存在骨不连趋势：肥胖（37%）；吸烟史（53%）；代谢性骨病（32%）；心血管疾病（37%）；短斜形骨折（89%）；开放性骨折（26%）；以及骨干近端三分之一骨折（68%）。我们建议向这些患者告知功能支具治疗可能增加骨不连的风险，并考虑手术固定的选择。
