1、提要目的:通过22例跟骨慢性骨髓炎手术清创过程中,分别对跟骨做部分切除和全切除,后放入负载抗生素骨水泥链,皮瓣封闭创口的临床病例研究,观察清创过程中跟骨全切除和部分切除对治疗跟骨骨髓炎的疗效。方法:将所收治的病例患者随机分为跟骨全切除组和部分切除组,术前拭创口分泌物细菌连续3d行分泌物细菌培养及药物敏感试验,记录药敏回示细菌所敏感的抗生素。手术室彻底扩创,去除创口周围瘢痕及肉芽组织,刮匙刮除所有跟骨骨质或者只刮除缺血坏死组织、死骨与缺血硬化骨至创面渗血良好(保留具有良好渗血的骨质)。用3.0%H2O2溶液与0.1%苯扎溴铵盐水反复冲洗浸泡创面
2、,生理盐水冲洗干净。后根据药敏提示放入自制负载抗生素素骨水泥链,冲洗缝合,取同侧腓肠神经皮瓣、小腿后侧逆行随意皮瓣、局部皮瓣等填塞死腔及修复皮肤缺损区,充分引流。按时行外科换药,记录创面生长情况以及细菌培养结果,观察创面愈合的质量。结果:患者全部获得随访,跟骨全切除组感染复发率明显低于跟骨部分切除组(p<0.05),皮瓣生长良好,伤口愈合良好,可行二期植骨重建跟骨外形。结论:跟骨慢性骨髓炎手术清创时全部刮除跟骨对降低感染复发率有着显著地促进作用,有较强的控制局部再感染作用,能加速创面的愈合,降低并发症。大大改善患者预后,降低患者精神经济负担。
3、适合二期进行跟骨植骨重建跟骨外形。临床效果优于跟骨部分切除组。关键词跟骨骨髓炎;清创;跟骨切除;感染;创面修复TheClinicalcurativeeffectobservationoftheextentofcalcanealresectiontotreattheCalcanealosteomyelitisSpeciality:OrthopaedicsofTCMAuthor:ZhaoXinglongTutor:Prof.SunLuAbstractObjective:22casesofchroniccalcanealosteomyelitisb
