摘要：
Objective To explore the clinical effects of different implants for the treatment of Mason II-III radial head fractures. Methods From January 2014 to October 2016, 90 cases of Mason II-III radial head fractures were selected for study. According to different implants for internal fixation, the patients were divided into absorbable rod group, screw group and Kirschner wire group, 30 cases each.Record three groups of operation time and intraoperative blood loss, and follow-up of 12 to 18 months was performed on the three groups of patients. The fracture healing time, MAYO elbow function score, and Btoberg-Morrey elbow function score were compared between the three groups. Results There was no significant difference in the three groups of operation time, intraoperative blood loss and fracture healing timeThere was no significant difference in the scores of the elbow function and the Btoberg-Morrey score between the three groups after fracture healing (P>0.05). The patients with absorbable rod group, screw group and K-wire group had better recovery of elbow function after surgery, and MAYO elbow function scores were (90.05±6.12) points, (91.26±7.83) points, (87.95±5.24) points, respectively, and the Btoberg-Morrey elbow function scores were (87.95±5.24) points, (92.18±8.09) points, and (89.13±6.27) points. There was no significant difference in the scores of the elbow function and the Btoberg-Morrey score between the three groups after fracture healing (P>0.05). The absorbable rod group, the screw group and the K -wire group of postoperative complications was 3.33% , 6.67% and 10.00% ,and there was no significant difference in the incidence of total complications between the three groups (P>0.05). Conclusion The absorbable rods, the screw group and the K-wire group have similar efficacy in the treatment of Mason Ⅱ-Ⅲ internal fixation of radial head fractures. However, the use of absorptive rods eliminates the need for secondary surgical removal of internal fixations. The fracture healing time is relatively short, and the incidence of postoperative complications is relatively low, which is worthy of clinical application.%目的 探讨不同置入物内固定治疗MasonⅡ、Ⅲ型桡骨头骨折的临床效果.方法 选取2014年1月-2016年10月收治的MasonⅡ、Ⅲ型桡骨头骨折90例为研究对象,根据内固定治疗的置入物不同,将患者分为可吸收棒组、螺钉组及克氏针组,每组各30例,记录三组的手术时间及术中出血量,并分别对三组进行12～18个月随访,比较三组骨折愈合时间及MAYO肘关节功能评分和 Btoberg-Morrey肘关节功能评分.结果 三组手术时间、术中出血量及骨折愈合时间比较,差异无统计学意义(P>0.05);可吸收棒组、螺钉组及克氏针组患者术后肘关节功能恢复均较好,其MAYO肘关节功能评分依次为(90.05±6.12)分、(91.26±7.83)分、(87.95±5.24)分,Btoberg-Morrey肘关节功能评分依次为(87.95±5.24)分、(92.18±8.09)分、(89.13±6.27)分,三组骨折愈合后肘关节功能MAYO 评分及Btoberg-Morrey评分比较差异均无统计学意义(P>0.05);可吸收棒组、螺钉组及克氏针组术后总并发症发生率分别为3.33%、6.67%、10.00%,三组总并发症发生率比较差异无统计学意义(P>0.05).结论可吸收棒、螺钉及克氏针在MasonⅡ、Ⅲ型桡骨头骨折内固定治疗中疗效相当,但应用可吸收棒治疗无需二次手术取出内固定物,骨折愈合时间相对较短,并发症发生率相对较低,值得临床推广应用.
