目的 探讨腕管位透视法在桡骨远端骨折掌侧接骨板固定术中的应用价值.方法 2015年3月至2016年5月,手术治疗新鲜桡骨远端骨折62例,其中48例采用单纯掌侧接骨板固定的患者纳入研究,男21例,女27例;年龄17～75岁,平均（43.6±10.6）岁.按照AO/OTA骨折分型,A型15例、B型11例、C型22例.手术均采用掌侧改良Henry入路,自桡侧屈腕肌和桡动脉之间进入,骨折复位后选用解剖锁定接骨板内固定,均为双皮质钻孔,螺钉长度的选择以较测深尺测量的数据短1～2 mm为宜,以防止背侧皮质穿出.术中接骨板固定完成后常规行标准正、侧位和腕管位透视（前臂旋后,肘关节屈曲60°～70°,腕关节背屈,放射线球管对着大鱼际方向进行透视）,将穿出皮质的螺钉更换为短螺钉后再行腕管位透视,直至无螺钉穿出背侧皮质为止;术后常规行CT扫描进一步验证腕管位透视法的有效性.分别统计正、侧位和腕管位透视螺钉穿出背侧皮质的百分率,对比正、侧位和腕管位透视的检出率并进行统计分析.结果 正、侧位透视发现5例患者螺钉穿出背侧皮质（10.4％,5/48）,腕管位透视发现包括上述5例在内的16例患者螺钉穿出背侧皮质（33.3％,16/48）,两种透视方法检出率的差异有统计学意义.另外有2例患者螺钉进入下尺桡关节,这仅在腕管位透视中能发现.对于穿出背侧皮质和进入下尺桡关节的螺钉术中即更换为短螺钉,总体的螺钉更换率为37.5％（18/48））.此18例患者术后CT扫描未见螺钉穿出背侧皮质或进入下尺桡关节.结论 与正、侧位透视相比,腕管位透视法能可靠地探测到螺钉的背侧皮质穿出,并能对下尺桡关节提供良好的术中透视,值得临床推广应用.
Objective To explore the application value of carpal shoot through view in the palmar plating of distal radius fractures.Methods From March 2015 to May 2016,there were 62 acute distal radius fractures received various operation in our department,in which 48 patients were only performed volar locked plating.Among these 48 cases,there were 21 males and 27 females,with ages ranging from 17 to 75 years （mean 43.6±10.6 years）.There were 15 cases of type A,11 cases of type B and 22 cases of type C distal radial fractures according to AO/OTA classification.All the operations were performed through modified Henry＇s approach between the radial artery and flexor carpi radialis.Once achieved satisfactory reduction,we performed rigid fixation of distal radius using anatomical locking plates.In all cases,bicortical drilling was performed.Screw lengths selected measured 1 to 2 mm less than the depth gauge number avoiding dorsal cortex penetration.After plate fixation of these 48 cases,standard posteroanterior and lateral radiographs were taken followed by the carpal shoot through view.To obtain carpal shoot through view,the patient＇s forearm was maximally supinated,the elbow flexed about 60°-70°and the wrist maximally dorsiflexed.The image intensifier beam is directed over the base of the thenar eminence.Compare the ratio of dorsal protrusion between standard view and carpal shoot through view,then statistical analysis was performed.After operation,CT scan was routinely taken to further test the effectiveness of carpal shoot through view.Results Five cases were detected dorsal cortex screw protrusion using standard posteroanterior and lateral views （10.4%,5/48）.There were totally 16 cases （including the former 5 cases） of dorsal screw penetration uncovered by the carpal shoot through view（33.3%,16/48.Statistically significant difference was existed between the two fluoroscopy methods.Additionally,in 2 cases,a screw had penetrated the distal radioulnar joint （DRUJ）,which was only apparent on the shoot t
