The assessment of tuberosity position and union in reverse shoulder arthroplasty (RSA) for complex proximal humerus fractures (PHF) has been carried out by means of routine simple radiographs. To evaluate the interobserver agreement and intraobserver reproducibility of the simple radiograph in comparison to the CT scan.
The position and consolidation of the tuberosities in 2 radiographic projections and in a CT scan of 32 consecutive patients operated on a RSA for PHF was assessed by 5 observers. Interobserver agreement and intraobserver reproducibility in both imaging tests were also assessed.
The interobserver agreement for the greater tuberosity position was 0.52 in the simple radiograph and 0.45 in the CT scan. For the greater tuberosity union, agreement was moderate in the simple radiograph (0.52), but fair in the CT scan (0.35). For the lesser tuberosity position and union, the agreement was fair in the radiograph and poor in the CT scan.
Only moderate agreement was observed in the assessment of the position and union of the tuberosities in the RSA for PHF in the simple radiograph and no improvement in it was seen for the 2D CT scan.
对于复杂肱骨近端骨折（PHF）的反肩关节置换术（RSA），一直通过常规简单X线片对结节位置和愈合情况进行评估。目的是评估与CT扫描相比，简单X线片在观察者间的一致性和观察者内的可重复性。
5名观察者对32例因PHF接受RSA手术患者的2张X线片和1次CT扫描中的结节位置和愈合情况进行评估。同时评估两种影像学检查在观察者间的一致性和观察者内的可重复性。
在简单X线片中，大结节位置的观察者间一致性为0.52，在CT扫描中为0.45。对于大结节愈合情况，简单X线片的一致性为中等（0.52），而CT扫描中的一致性为尚可（0.35）。对于小结节位置和愈合情况，X线片的一致性为尚可，CT扫描中的一致性较差。
对于PHF的RSA，在简单X线片中对结节位置和愈合情况的评估仅观察到中等一致性，二维CT扫描未见改善。
