Clinical value of X-ray digital tomosynthesis imaging in the diagnosis of traumatic osteoarthritis

ObjectiveTo investigate the clinical value of digital tomosynthesis(DTS) in the diagnosis of traumatic osteoarthritis.

MethodsThe results of digital radiography(DR) examination in 44 patients with traumatic osteoarthritis found that the suspected fracture or fracture line was not clear, and the image of internal and external fixation of fracture was not well.All cases were detected using DTS to obtain the consecutive tomographic images within the scanning range.The image quality between DTS and conventional DR was compared, and the clinical application value of DTS was evaluated.

ResultsThe reconstructed DTS images could display the bone and joint structure, the internal and external fixation artifacts could be removed, the fracture line in fresh fracture could be clearly showed, the callus formation in old fracture could be showed, the healing of broken end was clear.The occult fracture in 5 cases was found, and the fracture was excluded in 7 cases.

ConclusionsDTS is simple and easy to operate in the examination of traumatic osteoarthropathy, and has high diagnostic accuracy and low radiation dose.It has extremely important value in the diagnosis and review of complex structure fractures after internal and external fixation, and is worthy of further promotion.
