How is 3D flat panel C-arm imaging used in pelvic fracture surgery?


With the development of surgical technology and imaging, minimally invasive techniques are more and more widely used in pelvic fractures. Minimally invasive surgical treatment of pelvic fracture is to take a small incision, i.e., limited minimally invasive surgery for screw fixation technique after closed reset under three-dimensional flat C-arm fluoroscopy, which has the advantages of less surgical trauma, less pain for the patients, shorter surgical time, quicker recovery of the patients after surgery, and fewer surgical complications. It can greatly reduce the patient’s pain.

Pelvic fracture is a serious injury, most often seen in traffic accidents or fall from height injuries, industrial accidents and so on. Since the body weight is transmitted to the two lower limbs through the pelvis, and there are several organs and abundant blood vessels and nerves in the pelvis, pelvic fracture is usually accompanied by damage to the pelvic cavity, blood vessels and nerves in addition to the direct dysfunction.

The treatment of pelvic fracture has always been the difficulty of trauma orthopaedics, the complexity of the anatomical structure of the pelvis and its adjoining relationship, the pelvis has rich blood vessels, complex nerve alignment anatomical characteristics, and the pelvis anatomical shape is irregular, so the pelvic fracture surgery is very difficult, is the orthopaedic field of complex, and one of the challenging surgery.

Application of 3D flat-panel C-arm imaging in pelvic fracture surgery:

3D Flatbed C-Arm Imaging provides CT-like slice images (sagittal, coronal, and transverse images), and at the end of a single 3D scan, multiple fluoroscopic position images can be viewed without the need for multiple scans.

The 3D flat C-arm image contains more rich anatomical structure information such as the external shape of the bone, which can be used to visually evaluate whether the screw is in the sacral nerve root foramen, the position of the screw in relation to the vertebral body (information such as the LC-2 screw channel, the full length of the LC-2 screw, and the LCD line are also visually visible) as well as visually judging the restoration effect of the pelvic compression fracture, and so on.

Large field of view,Perlove medical 3D flat panel C-arm adopts 30cm×30cm flat panel detector, which is able to present more image details, and has the advantage of application for such as bilateral pelvic fracture type surgery or internal fixation of the posterior pelvic ring, and a single exposure can obtain all the images of the fracture part.

The key to the success of a minimally invasive surgery is not only the skill of the surgeon, but also high-tech equipment. The 3D flat C-arm can more realistically display the anatomical structure of the pelvis and the positional relationship between the fractures, forming a clear and accurate 3D stereo image, which is of high value in determining the type of pelvic fracture and deciding the treatment plan.
