Efficacy of nickel-titanium memory alloy in the treatment of multiple rib fracture combined with sternal fracture

Clinical efficacy and complications of nickel-titanium memory alloy in the treatment of multiple rib fractures combined with sternal fractures was investigated. A retrospective analysis of 123 patients with multiple rib fractures combined with sternal fractures admitted to First People's Hospital of Fuzhou from January 2013 to December 2015 was performed, including study group (treated with internal fixation by the nickel-titanium memory alloy, n=68) and control group (treated with internal fixation by partial pressure bandage, n=55). Μean arterial pressure (MAP), heart rate (HR), and visual analogue pain score (VAS) of the two groups before and after treatment were compared and analyzed. No significant difference in MAP, HR and VAS scores between groups was detected before treatment (P>0.05). After treatment, MAP score of study group was significantly higher, and HR and VAS scores were significantly lower (P<0.05). Μethod of internal fixation by the nickel-titanium memory alloy, with better efficacy than the traditional method of internal fixation by partial pressure bandage and less postoperative complications in the treatment of flail chest caused by multiple rib fractures combined with sternal fractures, is worthy of clinical application and promotion.
