骨又生替代髂骨植骨治疗四肢陈旧骨折的临床观察

The clinical observation of DTM in healing of old fracture

【目的】观察骨又生替代髂骨植骨治疗四肢陈旧骨折的作用。【方法】2006年7月-2008年7月我院骨科采用骨又生治疗36例四肢陈旧骨折;其中胫腓骨骨折13例,股骨粗隆间骨折7例,股骨干骨折8例,肱骨干骨折3例,桡骨骨折5例。所有病例分别于术后1、2、3、4个月和4个月以后X片复查。【结果】34例患者于术后4个月复查时骨折愈合。2例胫骨骨折患者于术后2个月复查时发现骨痂形成不明显,且断端骨质有吸收,给予局部冲击波治疗。其中1例术后4个月时可见明显骨痂形成,术后8个月骨折愈合。另外1例于术后3个月时行取髂骨植骨术,二次术后4个月骨折顺利愈合。【结论】骨又生可以作为一种替代髂骨植骨的植骨材料治疗四肢陈旧骨折,大大减轻患者的痛苦,节约医疗费用,值得推广应用。但其在某些部位(例如胫骨中下段)的应用效果仍有待进一步观察。

[Objective] To observe the clinical effect of Decalcification tooth matrices （DTM） in treatment of old fracture. [Methods] From July 2006 to July 2008, 36 cases of limbs old fracture were treated with DTM in our hospital. Among them , there were 13 cases of tibias and fibula fracture, 7 cases of femoral intertrochanteric fracture fracture, 8 cases of femoral shaft fracture, and 3 cases of humeral fracture, 5 cases of radius fracture. X-ray were obtained after 1 and 2, 3, 4months. [Results] 34 cases were healed within 4 months. There were 2 cases who have hardly callus formation in 2 months and healed with shock wave. One was healed in 8 months, the other was treated with bone graf op- eration in 3 months and was healed in 4 months after the second operation. [Conclusions] DTM can be the bone graf material to substitute flank bone to healing of limbs old fracture. DTM greatly reduced patient＇s pain, improved the medical quality and patients quality of life, saved the medical expense, was worth popularizing. But for some parts, e. g. the inferior segment of tibia, its result would do further observation.
