Being a proven method in trauma and spine surgery, intraoperative 3D imaging (CBCT) has intrinsic deficits in difficult anatomy and with artifacts because of metal implants. The purpose of this study was to evaluate the use of intraoperative computed tomography (iCT) in acetabular surgery.
Ten cases of acetabular fractures that were operated with intraoperative use of the mobile CT scanner Brainlab Airo were analyzed. Data were compared with a historical group of 17 patients.
Additional fluoroscopy time was 24.2 seconds (6-91), which was significantly lower than in the control group where it was 211.4 seconds (77-446; P < 0.000). Operation time did not differ significantly (iCT group 196.8 min [122-288], control group 240.8 min [71-411], P = 0.234).
iCT provides images of a reliable high quality and assessability. Radiation exposure to the staff is reduced while surgery time is not altered significantly. Quality of intraoperative imaging and thus patient care can substantially improve patient outcome.
术中三维成像（CBCT）在创伤和脊柱手术中是一种经过验证的方法，但在解剖结构复杂以及存在金属植入物导致伪影的情况下存在固有缺陷。本研究的目的是评估术中计算机断层扫描（iCT）在髋臼手术中的应用。
分析了10例术中使用移动CT扫描仪Brainlab Airo进行手术的髋臼骨折病例。将数据与17例患者的历史对照组进行比较。
额外的透视时间为24.2秒（6 - 91秒），显著低于对照组的211.4秒（77 - 446秒；P < 0.000）。手术时间无显著差异（iCT组196.8分钟[122 - 288分钟]，对照组240.8分钟[71 - 411分钟]，P = 0.234）。
iCT提供了可靠的高质量图像和可评估性。减少了工作人员的辐射暴露，同时手术时间没有显著改变。术中成像质量以及患者护理质量可显著改善患者预后。
