摘要: 背景 肱骨近端骨折分为不稳定骨折与稳定骨折,目前随着社会科技的进步与发展,针对不同Neer分型肱骨近端骨折患者选择手术或保守治疗仍存在争议,而锁定钢板治疗相较于传统治疗方案具有成角固定、肩袖损伤程度小以及可尽早康复锻炼等优势。目的 探讨不同Neer分型肱骨近端骨折经锁定钢板治疗后的疗效并评价其生物力学恢复情况。方法 选取2012年7月—2018年5月在南方医科大学顺德医院就诊并接受治疗的肱骨近端骨折患者49例,经X线确诊,其中NeerⅡ型16例、NeerⅢ型16例、NeerⅣ型17例。记录患者手术时间、术中出血量、骨折愈合时间以及术后并发症等情况;术后6个月采用Constant-Murley肩关节功能评分评估患者肩关节功能,采用Neer肩关节功能评分法评价患肢功能。结果 患者手术均顺利完成,不同Neer分型肱骨近端骨折患者手术时间、术后并发症发生率比较,差异均无统计学意义(P>0.05);不同Neer分型肱骨近端骨折患者术中出血量、骨折愈合时间比较,差异均有统计学意义(P<0.05)。术后6个月不同Neer分型肱骨近端骨折患者Constant-Murley肩关节功能评分比较,差异有统计学意义(P<0.05);其中NeerⅢ型肱骨近端骨折患者Constant-Murley肩关节功能评分低于NeerⅡ型,NeerⅣ型肱骨近端骨折患者Constant-Murley肩关节功能评分低于NeerⅡ型和NeerⅢ型(P<0.05)。不同Neer分型肱骨近端骨折患者Neer肩关节功能评分比较,差异无统计学意义(P>0.05)。Pearson相关性分析显示,Neer分型与术中出血量、骨折愈合时间呈正相关(r=0.894,P<0.001;r=0.783,P<0.001);与术后Neer肩关节功能评分呈负相关(r=-0.431,P<0.001)。结论 肱骨近端锁定钢板在治疗NeerⅡ型、Ⅲ型、Ⅳ型肱骨近端骨折时均具有较好的临床疗效及安全性,临床上治疗建议考虑锁定钢板治疗,但损伤基础直接影响了患者的术中出血量、术后骨折愈合时间及Constant-Murley肩关节功能评分情况,术后的治疗及康复需根据损伤基础,提高肩关节优良率。

Abstract: Background  Proximal humeral fractures are divided into unstable fractures and stable fractures.With the progress and development of social science and technology,it is still controversial to choose surgical or conservative treatment for different Neer classifications of proximal humeral fractures.Compared with traditional treatment,locking plate therapy has advantages such as angular fixation,less rotator cuff injury and early rehabilitation exercise.Objective  To study the efficacy and biomechanical recovery of locking plate in the treatment of proximal humeral fractures with different Neer classifications.Methods  A total of 49 patients with proximal humeral fractures who were treated in Shunde Hospital of Southern Medical University from July 2012 to May 2018 were selected.Diagnosed by X-ray,there were 16 cases of Neer type Ⅱ,16 cases of Neer type Ⅲ and 17 cases of Neer type Ⅳ.The operation time,intraoperative bleeding volume,fracture healing time and postoperative complications were recorded.The shoulder function was evaluated by Constant-Murley shoulder function score six months after operation,and the limb function was evaluated by Neer shoulder function score.Results The operations were completed smoothly.There was no significant difference in operative time and incidence of complications between patients with different Neer classifications of proximal humeral fractures(P>0.05);however,there were significant differences in blood volume and healing time in patients with different Neer classifications of proximal humeral fracture(P<0.05).There was significant difference in Constant-Murley shoulder function score between patients with different Neer classifications of proximal humeral fractures 6 months after operation(P<0.05);among them,Constant-Murley shoulder function score in patients with Neer type Ⅲproximal humerus fracture was lower than that of patients with Neer typeⅡ fracture,and Constant-Murley shoulder function score of patients with Neer type Ⅳ proximal humerus fracture was lower than that of patients with Neer type Ⅱ and type Ⅲ fracture(P<0.05).There was no significant difference in Neer shoulder function score among different Neer classifications of proximal humeral fractures(P>0.05).Pearson correlation analysis showed that Neer classification was positively correlated with intraoperative bleeding volume and fracture healing time(r=0.894,P<0.001;r=0.783,P<0.001),and was negatively correlated with Neer shoulder function score(r=-0.431,P<0.001).Conclusion The proximal humeral locking plate in the treatment of Neer type Ⅱ,Ⅲ,Ⅳof humerus fracture has better clinical efficacy and safety.Clinically,we recommend locking plate treatment,but the previous damage directly affects the patient's blood volume,postoperative fracture healing time and Constant-Murley shoulder function score.Therefore,postoperative treatment and rehabilitation should be taken according to the damage,so as to improve the rate of shoulder joint healing.
