Abstract
Introduction Investigation of the crossover sign (COS) in different degrees of tilt in pelvises made by three-dimensional printing of CT scans among patients with normal hip versions was carried out. Methods Radiology CT scans of 8 normal pelvises reconstructed in 3D and the effect of sequential tilting on the presence of the false-positive COS in 48 radiographs were investigated. Results The COS was seen in 77% of the AP radiographs during tilt changes. The average distance between the tip of the coccyx and the symphysis pubis was 32.06 ± 10.99 mm. Also, COSs were present in all radiographs from 6 degrees tilt and above. Conclusion Minor tilting of the pelvis can result in a false-positive crossover sign on AP plain radiographs.
期刊介绍：
Advances in Orthopedics is a peer-reviewed, Open Access journal that provides a forum for orthopaedics working on improving the quality of orthopedic health care. The journal publishes original research articles, review articles, and clinical studies related to arthroplasty, hand surgery, limb reconstruction, pediatric orthopaedics, sports medicine, trauma, spinal deformities, and orthopaedic oncology.
