Application of Titanium MatrixRib Fixation System in the treatment of flail chest

目的探讨MatrixRib钛肋骨固定系统在连枷胸治疗中的应用。方法对上海交通大学医学院附属同仁医院胸外科2014年1月至2015年1月58例连枷胸手术患者应用MatrixRib钛肋骨固定系统行肋骨内固定术。结果 58例连枷胸患者手术均顺利,术后恢复良好,术后疼痛评分明显降低(t=37.55,P<0.05)。平均手术时间(96.7±28.2)min,术中出血量(284.5±46.3)ml,术后住院时间(14.8±2.7)d。术后发生肺部感染3例、肺不张4例,经治疗后痊愈。患者术后切口均Ⅰ期愈合,胸廓形状恢复正常,反常呼吸消失。随访至术后6个月,复查胸部X线片,显示胸廓饱满,内固定牢固,骨折断端骨性愈合,无严重并发症。结论应用MatrixRib钛肋骨固定系统治疗连枷胸,手术操作简单方便、创伤小、组织相容性好、固定牢靠、并发症少,临床效果满意。

Objective To investigate the application of Titanium MatrixRib Fixation System in the treatment of flail chest. Methods From January 2014 to January 2015, 58 patients with flail chest underwent internal fixation with Titanium MatrixRib Fixation System in Tongren Hospital affiliated to Shanghai Jiao Tong University School of Medicine. Results All operations were successfully completed, with favorable postoperative recovery and significantly decreased postoperative pain score（t =37.55, P〈0.05）. The mean operation time was （96.7±28.2）rain, the mean volume of peri-operative bleeding was （284.5 ± 46. 3） ml, and the mean duration of postoperative hospital stay was （ 14. 8± 2. 7） d. Postoperative pulmonary infection and ateleetasis occurred in 3 cases and 4 cases, respectively, all of whom recovered after treatment. All incisions obtained healing by first intention. The shape of bony thorax recovered, and paradoxical respiration vanished in all cases after operation. The patients were followed up for 6 months, the chest X-Ray film demonstrated full thorax, firm internal fixationand osseous healing of fracture end, and there was nosevere complication. Conclusions Titanium MatrixRib Fixation System is simple and less invasive in the treatment of flail chest, with good tissue compatibility, stable fixation, less complications and favorable clinical results.
