摘要
目的：探讨加压骨接合术对颌骨骨折愈合的影响。方法：犬的下颌骨骨折模型在被加压接骨板固定后，定期观察外骨痂的生长情况，并作组织学切片检查与Ｘ线摄影。同时对４１例下颌骨骨折患者进行了临床治疗，观察其疗效。结果：在骨愈合过程中，无外骨痂形成与软骨化中间期，内骨痂直接横行连接骨折端，临床治疗效果满意，仅５例发现有不同的并发症。结论：用加压内固定治疗下颌骨骨折可以获得骨折的Ⅰ期骨愈合，并能减少或取代传统的颌间固定，并发症少。
Objective: To investigate the therapeutic effects of compressive internal fixation on
mandibular fracture. Methods: After the model of mandibular fracture was established in dogs,
the compression plates were used to treat the fracture. The external callus formation at the site
of fracture was observed at regular intervals. Meanwhile, histological and Xray examination
was conducted. Furthermore, 41 patients with mandibular fracture were treated and observed
likewise. Results: Fractures treated with compression plates showed no visible external
callus and sign of cartilage during the healing process, while the internal callus proceeded
directly across the narrow fracture line. The therapeutic effects of the compressive internal
fixation were satisfactory and complications were encountered only in 5 patients. Conclusion:
The use of compressive internal fixation ensures the primary bone healing, substitutes
conventional method of maxillomandibular fixation and decreases the occurring rate of co
