Abstract:

BACKGROUND: Due to the complex structure of the scapular fracture, X-ray plain film examination easily leads to misdiagnosis. With multi-slice spiral CT and three-dimensional reconstruction technology, three-dimensional reconstruction images can be intuitive, three-dimensional, multi-faceted to show fracture features.
OBJECTIVE: To evaluate application value of multi-slice spiral CT multiplanar reconstruction (MPR) and shaded surface display (SSD) reconstruction in the scapular fracture.
METHODS: Multi-slice spiral CT was used to scan 26 patients with complex fractures of the scapula. All data were entered into the computer workstation, followed by MPR and SSD reconstruction of post-processing to obtain the three-dimensional images of high-resolution. From different angles the fracture line courses, fracture displacement and angulation of the situation were observed, and fracture classification and simulation of surgical approach were performed based on three-dimensional image.
RESULTS AND CONCLUSION: Multi-slice spiral CT MPR and SSD reconstruction image fully displayed the location and extent of scapular fractures, with accordance rate between image and actual condition of 100%. A total of 26 cases suffered two or more fractures for a total of 81 fractures. According to standard Hardegger classification, there were 28 cases of scapular body fractures, 13 of scapular neck fractures, 11 fractures of labrum, 9 of glenoid fossa central transverse fracture, 8 of acromion fracture, 6 of scapular fracture, and 6 of coracoid process fracture. Results suggest that multi-slice spiral CT MPR and SSD reconstruction image shows visual images of scapular complex fracture, which are significant for the classification of the scapula fracture type, surgical approach and fixation selection, and effective for the diagnosis of scapular complex fracture.
