Between February 1996 and July 2000 eight patients (ages 35-74 years) with nine severely impacted humeral head fractures were operated on with the aim of preserving the humeral heads. Patients were treated surgically with open reduction, autologous bone grafting, and internal fixation with a screw-wiring technique. There were no complications and all patients were satisfied with the results. After 10-63 months there was no evidence of nonunion, arthritis, avascular necrosis, or loosening of implants. The mean Constant score was 83 (66-97) points. Results of this study support the observation that four-part valgus-impacted humeral head fractures without significant lateral displacement have a low incidence of avascular necrosis.
1996年2月至2000年7月期间，8例年龄在35至74岁之间、患有9处严重移位的肱骨头骨折的患者接受了手术，目的是保留肱骨头。患者接受了切开复位、自体骨移植和采用螺钉钢丝技术进行内固定的手术治疗。未出现并发症，所有患者对结果均满意。10至63个月后，没有骨不连、关节炎、缺血性坏死或植入物松动的迹象。Constant评分的平均值为83（66至97）分。本研究结果支持以下观察结果：无明显外侧移位的四部分外翻嵌插型肱骨头骨折缺血性坏死的发生率较低。
