Femoroacetabular impingement has recently become a recognized cause of disability and hip arthritis. Hip arthroscopy and femoroacetabular reshaping have been performed to treat this condition. Quantification of the excess femoral and acetabular bone requiring resection has been challenging with the less invasive arthroscopic technique. We describe the use of intraoperative computed tomography assessing osteochondroplasty during arthroscopic surgery to treat cam- and pincer-type femoroacetabular impingement. We also describe the technical steps and present the important radiologic findings we have been able to visualize. We found intraoperative computed tomography scanning to be a reliable and reproducible method of assessing the quality of femoroacetabular impingement surgery. We believe that femoroacetabular impingement surgery can be assessed intraoperatively by use of computed tomography scanning where corrections can be made if necessary.
髋关节撞击综合征最近已被认为是导致残疾和髋关节炎的一个原因。髋关节镜检查和股骨髋臼成形术已被用于治疗这种疾病。对于这种微创的关节镜技术，需要切除的多余股骨和髋臼骨的定量评估具有挑战性。我们描述了在关节镜手术中使用术中计算机断层扫描评估骨软骨成形术来治疗凸轮型和钳夹型髋关节撞击综合征。我们还描述了技术步骤，并介绍了我们能够观察到的重要影像学发现。我们发现术中计算机断层扫描是一种可靠且可重复的评估髋关节撞击综合征手术质量的方法。我们认为，如果需要，可以通过计算机断层扫描对髋关节撞击综合征手术进行术中评估，并进行相应的校正。
