文题释义:

网格状钛合金钢板:钛金属材料的机械强度与人体骨的机械强度不匹配,临床使用的材料大多是钛合金产品,如网格状钛合金钢板、钛合金螺钉等,网格状钛合金钢板无磁性,不会干扰医生对CT及MRI扫描结果的判断,用于重建胸壁有以下优势:①组织兼容性好,组织反应轻,无排异反应。②硬度适中,强度大,支撑力强,能维持骨性胸廓的完整性和稳定性,避免胸壁塌陷及发生反常呼吸。③质地坚韧,塑形好,可随胸壁的形状塑成相应的弧度,避免使用软性材料修补造成胸腔容积的减少。④网格状钛合金钢板为网状结构,结缔组织可通过网眼相互融合,有利于胸廓结构的塑性及稳定性。⑤操作方便,钛合金网经塑形后以数根不锈钢丝或钛丝固定于周边正常肋骨处即可。⑥价格合适。
钢丝网:不锈钢丝也是修补胸壁大块缺损的一种很好的材料,用不锈钢金属丝编成金属网重建胸壁硬性结构是一种安全、手术操作简单的方法之一,尤其在战时及条件简陋的基层单位遇到因外伤引起的胸壁大块缺损时,用不锈钢丝修复胸壁大块缺损不失为一种很好的方法。 

 

 

背景:研究表明,钛金属材料具有机械强度高、物理性能稳定、生物相容性好、耐腐蚀性好等优点,可安全应用于人体。
目的:对比网格状钛合金钢板及钢丝网修复胸壁缺损的安全性。
方法:纳入18例胸壁缺损患者,其中男11例,女7例,年龄19-65岁,其中9例采用网格状钛合金钢板进行修补,另9例采用钢丝网进行修补。修补后1周,采用目测类比评分评估疼痛情况;随访调查胸廓外形满意率及并发症发生情况。
结果与结论:两组患者随访1-7年,随访期间复查X射线片显示胸廓稳定性好,未出现网格状钛合金钢板、钢丝断裂及胸壁软化,呼吸功能恢复好,胸壁凹陷畸形不明显,胸廓外形满意率较高,网格状钛合金钢板组胸廓外形满意率显著高于钢丝网组(P < 0.05),并发症发生率显著低于钢丝网组(P < 0.05),两组胸壁缺损修复后1周的目测类比评分比较差异无显著性意义(P > 0.05)。结果表明,网格状钛合金钢板修复腹壁缺损具有良好的生物相容性及安全性,并可有效保持胸壁的稳定性。

Abstract:

BACKGROUND: Titanium materials have high mechanical strength, stable physical properties, good biocompatibility, and excellent corrosion resistance, which can be safely used in humans.
OBJECTIVE: To compare the safety of mesh-like titanium alloy steel plate versus wire mesh in the repair of chest wall defects.
METHODS: Eighteen patients with chest wall defects, 11 males and 7 females, with an age range of 19-65 years, were enrolled. The 9 of 18 patients were subjected to repair with mesh-like titanium alloy steel plate, and the other 9 patients underwent wire mesh repair. At 1 week after repair, visual analog scale scores were measured in the two groups, and patient’s satisfaction on the thoracic appearance and incidence of complications were surveyed during the follow-up.
RESULTS AND CONCLUSION: All patients were followed up for 1-7 years. During the follow-up, X-ray review displayed good thoracic stability and no fracture of titanium plate and wire mesh. Patients recovered well from respiratory dysfunction, with unapparent chest wall deformity and high satisfaction rate of the thoracic appearance. Moreover, compared with the wire mesh group, the satisfaction rate of the thoracic appearance was significantly higher (P < 0.05), but the incidence of complications was significantly lower in the titanium plate group (P < 0.05). At 1 week after repair, the visual analog scale scores had no difference between the two groups (P > 0.05). These findings indicate that the mesh-like titanium plate has good biocompatibility and safety to effectively maintain the stability of the chest wall.
