不锈钢材质T形锁定板修复锁骨近端骨折及胸锁关节脱位

背景：传统的锁骨近端骨折及胸锁关节脱位内固定的修复方法包括克氏针固定、克氏针张力带钢丝固定、锁骨钩钢板及普通T形钢板内固定等，但均存在固定不牢易脱落、容易损伤神经血管及影响胸锁关节微动等不足。 目的：探讨应用不锈钢材质T形锁定板置入内固定修复锁骨近端骨折及胸锁关节脱位的疗效，观察材料与宿主的生物相容性。 方法：单县中心医院2011年3月至2014年1月收治12例锁骨近端骨折及胸锁关节脱位患者，其中锁骨近端骨折7例，胸锁关节前脱位5例，均采用切开复位T形锁定钢板内固定治疗。 结果与结论：12例患者均得到随访，随访时间3-14个月，平均9个月。所有患者切口均甲级愈合，外观无局部隆起畸形，无胸骨后重要血管及脏器损伤等不良事件发生；X射线片检查骨折均愈合，无再脱位，无内固定断裂；末次随访Rockwood评分法评定肩关节功能优良率100%。提示，不锈钢材质T形锁定板置入内固定具有固定可靠、风险小、疗效满意的特点，患者能最大程度恢复肩关节功能，是治疗锁骨近端骨折及胸锁关节脱位的有效方法。中国组织工程研究杂志出版内容重点：生物材料；骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性；组织工程

Stainless steel T-shaped locking plate for repair of proximal clavicle fractures and sternoclavicular joint dislocation

BACKGROUND:Internal fixation methods for traditional proximal clavicle fractures and sternoclavicular joint dislocation include Kirschner wire, Kirschner wire with tension band, clavicular hook plate and ordinary T-shaped plate fixation. However, all of these are easy to fall off, damage nerves and blood vessels and affect the fine motion of the sternoclavicular joint. OBJECTIVE:To investigate the therapeutic effects of internal fixation with T-shaped stainless steel locking plate on proximal clavicular fractures and sternoclavicular joint dislocation as well as to observe the biocompatibility of materials with the host. METHODS:Twelve patients with proximal clavicular fractures and sternoclavicular joint dislocation were enrolled at Shanxian Central Hospital from March 2011 to January 2014, including seven cases of proximal clavicular fractures and five cases of sternoclavicular joint dislocation. All of patients were subject to open reduction and internal fixation with T-shaped locking plate. RESULTS AND CONCLUSION:All the 12 patients were followed up for 3-14 months, with an average of 9 months. All incisions healed well, with no local eminence. No major substernal blood vessels and organ damage occurred. X-ray films showed that fractures healed without further dislocation and steel plate fracture. At the last follow-up, Rockwood scoring system showed that the excellent rate of shoulder function was 100%. These findings indicate that the internal fixation with stainless steel T-shaped locking plate is reliable and effective in the treatment of proximal clavicle fractures and sternoclavicular joint dislocation, with low risks and satisfactory outcomes, by which, patients can maximize the recovery of shoulder function.
