摄影体位改良对肱骨近端骨折术后的评估价值

摘要

Objective To compare the values of two photography positions for the evaluation after locking plate implantation of the proximal humeral fracture patient.Methods Totally 200 proximal humeral frature patients after locking plate implantation had the front and lateral shoulder joint X-ray films with the conventional and improved photography positions analyzed retrospectively.Post-operative evaluation was carried out with double-blind method from the aspects of morphology of humeral head,condition of locking plate and screw,humeral head angle and bone cortex around humerus.Results Improved photography position behaved better than the conventional position in displaying morphology of humeral head,condition of locking plate and screw,humeral head angle and bone cortex around humerus.Conclusion Improved photography position is recommended to photograph the lateral side of the locking plate for post-operative evaluation.%目的:比较2种X线摄影体位对肱骨近端骨折锁定钢板植入术后的评估价值.方法:回顾性对比分析由常规摄影体位和改良后摄影体位分别采集的200例肱骨近端骨折锁定钢板植入术后进行X线复查的肩关节正侧位片,利用双盲法分别从肱骨头的形态、锁定钢板螺钉的形态、肱骨头干角及肱骨周边骨皮质4个方面的显示情况进行术后评估.结果:改良后的摄影体位对肱骨头的形态、螺钉的形态、肱骨头干角以及骨折处骨皮质的显示效果均优于常规摄影体位的图像.结论:肱骨近端骨折锁定钢板植入术后进行X线摄影复查时,建议使用改良后的摄影体位,以锁定钢板为目标,拍摄钢板的正侧位,更加有利于临床进行术后评估.
