文题释义:
不稳定型骨盆骨折:人体的骨盆是由左右髋骨和骶、尾骨以及其间的韧带连接构成,而髋骨是由髂骨、坐骨及耻骨联合组成的不规则骨骼,不稳定性骨盆骨折发生后,骨盆的前后环联合损伤并发生移位,使骨盆稳定性遭受破坏,且常伴有盆壁软组织损伤,如尿道、直肠、膀胱、阴道、神经等。
炎性因子:在不同的金属内固定材料置入人体之后,在早期大多会出现不同程度的周围组织炎性反应等。随着时间的推移,炎性反应会逐渐减轻。如果相应的材料生物相容性不佳,则容易导致炎性反应时间的延长等。另外,还会导致全身性反应的出现,包括炎症反应和超敏反应及免疫刺激等。
 
摘要
背景:在不同的金属内固定材料置入人体之后,在早期大多会出现不同程度的周围组织炎性反应等。如果相应的材料生物相容性不佳,则容易导致炎性反应时间的延长等。
目的:分析松质骨螺钉置入内固定修复不稳定型骨盆骨折的炎性因子水平变化及其生物相容性。
方法:纳入61例不稳定型骨盆骨折患者,随机分为2组,观察组(29例)和对照组(32例),观察组29例实施松质骨螺钉置入内固定治疗,对照组32例实施常规保守治疗。治疗后随访12个月,观察2组患者的Majeed功能评分、炎性因子水平变化以及不良事件发生情况,并进行对比。
结果与结论:①Majeed功能评分:较之治疗前,2组患者的评分均显著上升(P均<0.05)。且治疗后12个月观察组的评分显著高于对照组(P < 0.05);②炎性因子水平:较之治疗前,2组患者的白细胞介素6、C-反应蛋白、肿瘤坏死因子α水平均显著下降(P< 0.05),但2组治疗前后进行组间比较,各指标差异均无显著性意义(P > 0.05);③不良事件:术后1例观察组患者出现切口感染;对照组则有4例患者出现切口感染现象,1例出现骨不连,1例出现骨坏死。上述患者均及时接受对症处理,并痊愈,未出现死亡病例。2组的不良事件发生率差异有显著性意义(P < 0.05);④结果表明,松质骨螺钉置入修复不稳定型骨盆骨折可以获得理想的内固定效果,且具有良好的生物相容性。

Abstract:

BACKGROUND: After different metal fixation materials are implanted into the human body, peripheral tissue inflammatory response to varying degrees will appear in the early stage. Poor biocompatibility of the corresponding materials will lead to prolonged duration of inflammatory reaction. 

OBJECTIVE: To investigate the inflammatory factor level changes and biocompatibility of cancellous bone screw fixation in treatment of unstable pelvic fractures.
METHODS: A total of 61 patients with unstable pelvic fractures were randomly divided into the observation group (29 cases) and the control group (32 cases). The 29 patients in the observation group underwent cancellous bone screw fixation. The 32 patients in the control group underwent conventional therapy. During 12 months of follow-up, Majeed function score and inflammatory factor level changes and adverse events were observed and compared between the two groups. 

RESULTS AND CONCLUSION: (1) Majeed function scores were significantly higher in both groups after treatment as compared with that preoperatively (all P < 0.05). The Majeed function scores were significantly higher in the observation group than in the control group 12 months after treatment (P < 0.05). (2) Inflammatory factor levels: Interleukin 6, C- reactive protein, and tumor necrosis factor alpha levels were significantly lower in both groups after treatment as compared with that preoperatively (all P < 0.05). No significant difference in above indexes was found between the two groups before and after treatment (P > 0.05). (3) Adverse events: one case affected incision infection after operation in the observation group. In the control group, four patients experienced incision infection. One suffered from nonunion, and one had bone necrosis. Above patients were treated in time, and were cured, so there were no deaths. There were significant differences in the incidence of adverse events between the 2 groups (P < 0.05). (4) The research results show that cancellous bone screw fixation for unstable pelvic fractures can obtain satisfactory clinical results, and have good biocompatibility.
