经皮微创松质骨取骨器的研制及临床应用

目的探讨自制微创取骨器在髂骨取骨的临床应用效果。方法2007年2月～2008年10月采用自行研制的微创取骨器取松质骨35例,自髂前上棘后1cm至髂嵴结节髂骨较厚的区域取骨。结果取骨量1～4cm3,平均2.37cm3;微创取骨器取骨的操作时间3～5min;出血量1～2ml;并发症发生率5.7%（2/35）。结论使用微创取骨器取松质骨,方法可靠,可满足部分植骨手术的需要。

Clinical Application of Percutaneous Minimally Invasive Cancellous Bone Harvester

Objective To investigate the value of self-made minimally invasive cancellous bone harvester. Methods From February 2007 to October 2008, cancellous bones of 35 cases were obtained by the self-made minimally invasive cancellous bone harvester from the area between the point 1 cm posterior to the anterior superior iliae spine and the tubercle of iliac crest. Results The average amount of harvested bone is 2.37 cm^3 （range 1 - 4 cm^3 ）. The operation time ranged 3 - 5 min, and the blood loss was 1 -2 ml. The incidence rate of complications was 5.7% （2/35）. Conclusions The minimally invasive bone harvester is safe and reliable. It can be used for some bone grafting surgeries .
