注射型硫酸钙强化锁定系统治疗老年骨质疏松性肱骨近端骨折

背景：肱骨近端内固定锁定系统治疗粉碎性骨质疏松性肱骨近端骨折效果良好,但在临床应用中容易发生内固定松动、骨折再移位等并发症。目的：分析微创注射型硫酸钙强化肱骨近端内固定锁定系统治疗老年骨质疏松性肱骨近端骨折的临床效果。方法：将50例老年肱骨近端骨折患者随机分为对照组（n=21）与实验组（n=29）。对照组在微创技术下使用肱骨近端内固定锁定系统固定治疗,实验组在微创技术下使用肱骨近端内固定锁定系统固定治疗,并使用微创注射型硫酸钙进行注射强化。结果与结论：随访11-25个月,两组骨折均愈合。两组骨折愈合时间、肩关节Neer评分优良率差异无显著性意义,但实验组并发症发生率及复位丢失高度明显低于对照组（P〈0.05）。表明微创注射型硫酸钙强化肱骨近端内固定锁定系统治疗老年骨质疏松性肱骨近端骨折具有创伤小、固定可靠、并发症少、关节功能恢复好等优点。

Proximal humeral internal locking system and injectable calcium sulfate graft for the treatment of osteoporotic proximal humeral fractures in elderly patients

BACKGROUND：There are some satisfactory curative effect for the treatment of comminuted osteoporotic proximal humeral fractures with proximal humeral internal locking system, but always following some complications, such as displacement and loosen of internal fixation. OBJECTIVE：To investigate the clinical effect of proximal humeral internal locking system and minimally invasive injectable graft for the treatment of osteoporotic proximal humeral fractures in elderly patients. METHODS：The 50 patients with proximal humeral fractures were randomly divided into two groups：the experimental group （n=29） and the control group （n=21）. The experimental group was treated with proximal humeral internal locking system in minimal invasion. The control group was treated with proximal humeral internal locking system in minimal invasion, and augmentation with minimally invasive injectable graft. RESULTS AND CONCLUSION：The follow-up period was 11-25 months. All achieved fracture healing. There was no significant difference in fracture healing time and the excellent and good rate of shoulder Neer score between two groups. The complication rate and the restoration loss height of the experimental group were lower than those of the control group （P 0.05）. It indicates that proximal humeral internal locking system and minimally invasive injectable graft is an effective method for the treatment of osteoporotic proximal humeral fractures in elderly patients with the advantages of relatively minor trauma, stable fixation, fewer complication, and better function.
