There was no disordered bony callus at ATMFS sides. Successive bone callus can be observed at 4 weeks after operation.
ATMFS侧骨折端无凌乱骨痂，术后4周即可见连续性骨痂通过骨折线。
While in material of natural bone group, fracture line disappeared after 8 weeks with dense bone callus at the site of bone defects, and by 12 weeks bone marrow still not recanalized.
而单纯支架组8周骨折线消失，缺损处有大量骨性骨痂包绕，12周骨皮质连续，骨塑形较差，髓腔未通。
The healing style was characterized by plate bone substitution, with no disordering callus.
骨愈合形式均呈骨板样骨替代，未见无序骨痂出现。
The healing style was characterized by plate bone substitution, with no disordering callus .
骨愈合形式均呈骨板样骨替代，未见无序骨痂出现。
The healing style was characterized by plate bone substitution, no disordering callus was observed.
骨愈合形式均呈骨板样骨替代，未见凌乱骨痂出现。
Conclusions it is a good method to treat bone defect following children femoral osteomyelitis with callus lengthening after interlocking nail implantation.
结论植入带锁髓内钉后进行骨痂延长术是治疗儿童股骨骨髓炎后骨缺损的良好方法。
RESULTS:Roentgenographic scores and callus density at bone defects in trial group were better than those in control group at postoperative 3,6,12weeks.
结果：实验组骨缺损放射影像学评分以及新生骨痂的密度在3，6，12周均优于对照组。
Histological alterations during fracture healing were observed, and percentage of trabecular bone, cartilage and fibrous tissue in the bony callus was determined.
观察骨折愈合的组织学变化，并测定骨痂中小梁骨、软骨、纤维组织所占百分比。
Follow-up radiographs were used to assess alignment, bone contact and callus formation.
随访时拍片来看对线的情况，骨折块的接触情况和骨痂的生成情况。
All patients underwent bone specific alkaline phosphatase (BSAP) and imaging follow-up to observe callus formation and fracture healing.
所有患者均行骨特异性碱性磷酸酶活性检测和影像学随访，观察骨痂形成及骨折愈合情况。
In keeping with this principle, such an internal fixation operation led to primary bone-fracture consolidation without visible callus formation.
与这一原则相映，如此内固定手术可导致无可见骨痂形成的一期骨愈合。
At 2 weeks after fresh autogenous bone grafted, there was some new callus in bone defection.
新鲜骨块植入后第2周，骨缺损处可见新生骨。
The autologous bone marrow transplantation combined with bone allograft probably promotes the early-stage development of the callus, accelerates the bone healing, shorten the hospitalization staying.
提示自体骨髓移植复合人工骨较单纯的人工骨移植或自体骨髓移植更能促进早期骨痂反应，加速骨折后骨缺损愈合，缩短骨愈合时间及住院时间。
