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 intra-pelvic cavity view, blood vessels and nerves injury in addition to the direct cause of dysfunction.
The treatment of pelvic fracture has always been a difficult point in orthopedic trauma, with complex anatomical structures and their adjoining relationships in the pelvis, rich blood vessels in the pelvis, complex anatomical features of nerve alignment, and irregular pelvic anatomy, so pelvic fracture surgery is very difficult, and it is one of the most complex and challenging surgeries in the field of orthopedic surgery.
With the development of surgical techniques and imaging, minimally invasive techniques are more and more widely used in pelvic fractures. Minimally invasive surgical treatment of pelvic fracture is to take small incision, i.e., limited minimally invasive surgery for screw fixation after closed reduction under C-arm fluoroscopy, which has the advantages of small surgical trauma, less pain to the patient, shorter surgical time, quicker recovery of the patient after surgery, and fewer surgical complications. It can greatly reduce the patient’s pain.
Perlove 3D flat C-arm, through the 190 ° comprehensive information acquisition, through the pulse fluoroscopy, the acquisition of 100 frames or 380 frames of images, volumetric reconstruction into three-dimensional stereo images, as well as the corresponding sagittal, coronal, cross-section.
The value of three-dimensional imaging in pelvic fracture surgery:
3D imaging provides CT-like slice images (sagittal, coronal, and transverse images), and at the end of a single 3D scan, multiple fluoroscopic positional images can be viewed without the need for multiple scans.
The 3D image contains richer anatomical structure information such as the external shape of bones, which can be used to intuitively 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 intuitively visible), as well as intuitively judging the restoration effect of pelvic compression fractures.
Large field of view,Perlove 3D flat-panel C-arm adopts 30cm×30cm flat-panel detector, which is able to present more image details, which is advantageous for applications such as bilateral pelvic fracture type of surgery or internal fixation of the posterior pelvic ring, and one exposure can obtain all the images of the fracture site.
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 image, which is of high value in determining the type of pelvic fracture and deciding the treatment plan.
