氰基丙烯酸酯类骨黏合剂：应用在骨折骨缺损修复中的潜能和优势

BACKGROUND: Cyanoacrylate adhesives are widely used in medical fields such as hemostatic agent, wound closure and medical embolism. OBJECTIVE: To point out the problems and focus of research of cyanoacrylate adhesives used in the orthopedic field through reviewing the properties and research progress of cyanoacrylate adhesives in fracture fixation and relevant modification research. METHODS: Articles related to cyanoacrylate as bone adhesives and relevant modification studies were retrieved in CNKI and PubMed databases (2008-01/2015-12). The key words were “cyanoacrylate, fracture, bone defect” in Chinese and English, respectively. A total of 40 articles based on inclusion and exclusion criteria were obtained for the further review. RESULTS AND CONCLUSION: Cyanoacrylate adhesives have been widely used in medical fields such as vascular anastomosis and embolization in vascular surgery, soft tissue repair, skin closure. However, it is still in the stage of animal experiments as bone adhesives for fracture fixation in load-bearing parts. Importantly, there are two problems to be solved. First, cyanoacrylate adhesives could not complete the fixation of fracture in the load-bearing parts because of viscosity and biomechanical deficiencies. Second, it still needs to observe whether the adhesives on the fracture end hinder the growth of bone. In conclusion, modification of cyanoacrylate shows a great potential in fracture fixation compared with traditional internal fixation methods. This new method has a wonderful prospect in clinical treatment of fractures.

DAMIS入路对同期双侧全髋关节置换术患者术后康复的影响

目的:探究DAMIS微创入路和传统前外侧入路对同期双侧全髋关节置换术患者术后早期康复的影响。方法:回顾性分析我科同期双侧人工全髋关节置换术的64例(128髋)患者的病例资料。其中接受DAMIS微创入路(DAMIS组)34例,传统前外侧入路(对照组)30例,通过比较两组的切口长度、手术时间、术中出血量、住院时间、并发症和Harris髋关节评分评估临床疗效,术后定期复查X线片评估假体稳定性、骨长入等情况。结果:全部病例随访时间1~30个月,平均22.4个月。平均切口长度DAMIS组为(9.62±1.53)cm,对照组为(11.87±2.14)cm(t=4.88,P<0.01);手术时间DAMIS组为(168.37±13.54)min,对照组为(172.10±16.81)min(t=0.98,P>0.05);术中出血量DAMIS组为(323.57±91.49)m L,对照组为(475.66±121.73)m L(t=5.69,P<0.01);平均住院时间DAMIS组为(6.50±1.42)d,对照组为(10.40±1.75)d(t=9.84,P<0.01)。Harris髋关节评分DAMIS组从术前(44.60±7.33)分提高至末次随访的(94.36±5.51)分,差异有统计学意义(t=31.64,P<0.01);对照组从术前(40.91±8.54)分提高至末次随访的(80.58±6.27)分,差异有统计学意义(t=20.51,P<0.01);两组间末次随访评分(t=9.36,P<0.01)差异有统计学意义。患者术后切口均Ⅰ期愈合,无下肢深静脉血栓及血管神经损伤等并发症出现,随访期间假体周围可以看到明显的骨长入,无1例出现假体松动和感染。结论:DAMIS同期双侧微创全髋关节置换术的早期疗效满意,相对于传统前外侧入路置换术具有术中出血少、术后无需引流、早期下地活动、恢复快等优点,能明显改善髋关节的功能,有助于术后早期康复,但远期疗效有待进一步观察。     

股骨近端防旋髓内钉内固定与髋关节置换治疗高龄骨质疏松性股骨粗隆间骨折患者的疗效及围术期处理

目的比较股骨近端防旋髓内钉(PFNA)内固定与髋关节置换(HA)治疗高龄骨质疏松性粗隆间骨折患者的临床疗效及围术期处理。方法 50例高龄骨质疏松性股骨粗隆间骨折患者分为PFNA组和HA组,观察并比较术后并发症发生率、手术时间、术中出血量、住院时间、术后下地时间、术后髋关节Harris功能评分。结果两组住院期间无死亡病例,PFNA组手术时间及术中出血量显著少于HA组(P0.05),而术后下地时间明显长于HA组(P0.05),两组住院时间及术后髋关节Harris评分差异无统计学意义(P0.05)。结论 PFNA内固定的优势在于手术创伤小,出血少,适用于Evans分型Ⅰ~Ⅱ型的稳定型粗隆间骨折;而HA优势在于下地功能锻炼时间早,术后并发症少,更适用于Evans分型Ⅲ型以上高龄患者及病理性骨折、骨质疏松严重等特殊类型骨折。应根据具体临床情况的不同制定个体化治疗方案。
