In the best of our knowledge there is not yet in the literature a measurement able to assess post reduction stability of distal radius fractures.
to study the relationship between our newly introduced Pacetti's line, anatomical reduction of DRFs and post-reduction stability of fractures.
Patients/Participants: 230 patients (122men, 108women) who sustained a dorsally displaced distal radius fracture. Close reduction procedures attempted; below elbow cast applied.
FOLLOW-UP: Pacetti's line used on true AP and lateral view xrays after reduction and casting (T0) and at 7-14 days (T1-T2).
Assessment and prediction of early displacement of DRFs.
The Pacetti's line intersected the lunate bone in 162 cases (70.4%) after anatomical reduction, of which 20.4% (N=33) lost anatomical reduction. Cramer's V test: significant relationship between transition of Pacetti's line through the semilunar bone and stability of anatomical reduction at T0 follow-up (p<0.001, Cramer's value=0.83). The Pacetti's line intersected the lunate bone in 119 cases (51.7%) at 7-14 days follow-up. None of patients lost anatomical reduction. Cramer's V test: significant relationship between transition of Pacetti's line through the semilunar bone and stability anatomical reduction at T1 and T2 follow-up (p<0.001, Cramer's value=0.73).
We strongly recommend the use of the Pacetti's line as it seems to provide reliable prediction of further fracture displacement and consequently of definitive management. The Pacetti's line seems to represent a very useful tool providing simple, feasible, efficient and reliable information on DRFs characteristics and natural course.
据我们所知，目前文献中尚无一种可评估桡骨远端骨折复位后稳定性的测量方法。
研究我们新引入的 Pacetti 线、桡骨远端骨折的解剖复位与骨折复位后稳定性之间的关系。
患者/参与者：230 例（122 例男性，108 例女性）均为背侧移位的桡骨远端骨折患者。尝试闭合复位，应用肘下石膏固定。
在复位和石膏固定后（T0）及 7-14 天（T1-T2）时，使用 Pacetti 线拍摄真正的前后位和侧位 X 光片。
评估和预测桡骨远端骨折的早期移位。
162 例（70.4%）患者在解剖复位后 Pacetti 线穿过月骨，其中 20.4%（N=33）失去解剖复位。Cramer's V 检验：T0 随访时 Pacetti 线穿过月骨与解剖复位稳定性之间存在显著关系（p<0.001，Cramer 值=0.83）。119 例（51.7%）患者在 7-14 天随访时 Pacetti 线穿过月骨。无患者失去解剖复位。Cramer's V 检验：T1 和 T2 随访时 Pacetti 线穿过月骨与解剖复位稳定性之间存在显著关系（p<0.001，Cramer 值=0.73）。
我们强烈推荐使用 Pacetti 线，因为它似乎可以可靠地预测骨折进一步移位，并因此确定最终的治疗方案。Pacetti 线似乎是一种非常有用的工具，可以提供有关桡骨远端骨折特征和自然病程的简单、可行、有效和可靠的信息。
