目的探讨利用智能手机角度测量软件在人工全髋关节置换术(total hip arthroplasty,THA)中测量髋臼假体植入角度的准确性以及应用价值。方法 2012年6月-2015年9月,在50例患者THA术中利用智能手机的角度测量软件测定髋臼假体外展角及前倾角。男24例,女26例;年龄37~83岁,平均71岁。左髋22例,右髋28例。关节置换原因:股骨颈骨折34例,股骨头缺血性坏死16例。均排除髋臼发育异常。术后1周摄骨盆正位X线片,利用PACS系统测量髋臼假体外展角及前倾角。采用组内相关系数评估观察者自身测量的可靠性,Mann-Whitney U检验比较术中手机测量及术后PACS系统测量结果差异;定义术后PACS系统测量髋臼假体角度大于手机测量值为+,反之为-,计算术中及术后角度测量误差范围。结果术中手机测量及术后PACS系统测量髋臼前倾角、外展角的组内相关系数为0.84。术中手机测量髋臼假体外展角为(44.02±1.33)°,前倾角为(17.62±2.20)°;术后PACS系统测量髋臼假体外展角为(44.74±4.05)°,前倾角为(17.22±5.57)°;两种方法测量值比较,差异无统计学意义(Z=...

Objective To evaluate the accuracy of using smartphone to measure the angle of acetabular component in total hip arthroplasty(THA). Methods Between June 2012 and September 2015, the acetabular abduction and anteversion angles were measured in 50 patients undergoing THA. There were 24 males and 26 females, aged 37 to 83 years(mean, 71 years). The left hip was involved in 22 cases and the right hip in 28 cases. Of 50 patients, 34 suffered from fracture of the femoral neck, and 16 suffered from avascular necro...

人工全髋关节置换术(total hip arthroplasty,THA)中对髋臼假体前倾角及外展角的精确把握是手术成功的关键之一。目前,绝大部分THA术中髋臼假体植入角度由术者主观评估判断,与术者自身手术技巧及熟练程度有密切关系。随着智能手机的广泛普及,利用手机角度测量软件,通过手机摄像
