Methods : Vascularized heterotopic fibula was transplanted to the anterior-lateral part of the femoral neck. The fibula artery and vein were anastomosised with lateral circumflex artery and vein. Results : One hundred and twenty-nine cases of non-union femoral neck fracture were treated with vascularized fibula graft in our hospital from 1982 to 2002. Eighty-seven cases of them were followed up for 3 to 19 years with functional and X-ray examination. The percentage of fracture healing and effect were 94. 3 and 81. 6, respectively. Conclusion:The fibula with blood supply has a synergistic fixation impact on the non-union femoral neck fractures. The fibula is solid enough for supporting the femoral head and preventing it from collapse. The vascularized fibula grafting, by providing blood supply to the affected femoral head and neck, could promote the femoral head restoration and reconstruction. In addition, the periosteum of fibula plays a role in fracture healing.展开更多

Methods: A total of 71 patients (44 males and 27 females, aged 16-55 years, mean=34.32 years) with fresh canalicular laceration were treated in our hospital from March 2003 to April 2008. Under a microscope, 37 patients were treated with lacrimal sac anastomosis (the treatment group) and 34 with end-to-end anastomosis (the control group), detaining silicone tubes till 3 months later. Results: The cure rate of the treatment group (89.19%) was significantly higher than that of the control group (55.56%). Class I cure rates were 70.27% in the treatment group and 47.06 % in the control group, and the difference between the two groups was significant (P〈0.05). Postoperative inflammatory reactions had significant influences on the two kinds of anastomosing methods, but no significant difference was found between the two groups (P〉0.05). Conclusions: When the distance from the broken end to the dacryon is over 7 mm, especially when it is necessary to find the paranasal broken end of the lacrimal canaliculus with dacryocystotomy, canaliculus-to-lacrimal sac anastomosis is a better treatment method than end-to-end anastomosis for laceration of lacrimal canaliculus.展开更多
