In this study, we examined the use of a 2.0-mm locking bone plate/screw system in mandibular surgery.
All patients who were treated with a 2.0-mm locking bone plate/screw system during an 8-month period for fractures of the mandible or other defects of the mandible were prospectively studied. Ease of use of locking plate/screw system, characteristics of the fractures and defects, and complications were tabulated.
A total of 80 fractures in 59 patients were treated with the 2.0-mm locking plate/screw system. One hundred two 2.0-mm locking plates were applied to the 80 fractures; 58 fractures received 1 plate and 22 fractures received 2 plates. There were no intraoperative difficulties associated with their application. Fracture reductions were considered to be excellent in all cases. At the latest follow-up, all fractures had healed, but 2 patients had slight malocclusions. Six patients developed postsurgical infections. Only 1 patient required hospitalization for treatment of the infection; all others were managed in the outpatient clinic. Four patients required removal of their plates for varying reasons.
The use of a 2.0-mm locking plate/screw system was found to be simple and to provide sound fixation in all cases.
在本研究中，我们检查了2.0毫米锁定接骨板/螺钉系统在下颌骨手术中的应用。
对在8个月期间接受2.0毫米锁定接骨板/螺钉系统治疗下颌骨骨折或其他下颌骨缺损的所有患者进行前瞻性研究。将锁定接骨板/螺钉系统的易用性、骨折和缺损的特征以及并发症制成表格。
59例患者共80处骨折接受了2.0毫米锁定接骨板/螺钉系统治疗。102块2.0毫米锁定接骨板应用于80处骨折；58处骨折用1块接骨板，22处骨折用2块接骨板。应用过程中未出现术中困难。所有病例的骨折复位均被认为极佳。在最近一次随访时，所有骨折均已愈合，但2例患者有轻微咬合不正。6例患者发生术后感染。仅1例患者因感染需要住院治疗；其他所有患者在门诊处理。4例患者因各种原因需要取出接骨板。
发现使用2.0毫米锁定接骨板/螺钉系统操作简单，且在所有病例中均能提供可靠的固定。
