This level IV case series study prospectively evaluated patients with atrophic proximal humerus nonunions stabilised with a locking 90 degree blade plate. All patients were women with an average age of 69 years (range 56-78). Time from trauma to nonunion treatment averaged 23 months. Five patients had had previous surgical treatments. Two patients had a history of infection and one patient with active infection was reconstructed in two stages. Follow-up averaged 22 months (range 18-36); union was achieved in all seven cases after an average of 5.85 months. The DASH score at the last follow-up averaged 25 points and Constant score averaged 72.7 points. No patient required additional procedures. At the last follow-up all patients were free of infection, and there were no cases of avascular necrosis. The results with locked 90 degree blade plates in atrophic nonunions of the proximal humerus in adults were favourable in this series.
本 IV 级病例系列前瞻性评估了使用锁定 90 度刀片板稳定的萎缩性肱骨近端骨不连患者。所有患者均为女性，平均年龄 69 岁（范围 56-78 岁）。从创伤到骨不连治疗的时间平均为 23 个月。五名患者曾接受过手术治疗。两名患者有感染史，一名活动性感染者分两期重建。平均随访 22 个月（范围 18-36 个月）；所有 7 例患者在平均 5.85 个月后均达到愈合。末次随访时 DASH 评分为 25 分，Constant 评分为 72.7 分。无患者需要额外的手术。末次随访时，所有患者均无感染，无一例发生股骨头坏死。在本系列中，使用锁定 90 度刀片板治疗成人萎缩性肱骨近端骨不连的结果是有利的。
