Abstract
OBJECTIVE: The aim of the study was to analyze the imaging findings of Die-punch fracture of intermediate column of the distal radius, and to explore the clinical application value of image classification. METHODS: The clinical data of 45 patients who were admitted to our hospital from May 2010 to October 2016 were analyzed retrospectively. All patients met the inclusion criteria for Die-punch fracture. X-ray and CT scan were performed to examine the fracture, and the results were assessed by two doctors in a double blind method. Finally, the image classification of Die-punch fracture was formulated. RESULTS: According to the imaging features of Die-punch fracture, it was divided into four types: type I (dorsal type, 15 cases), type II (volar type, 8 cases), type III (splitting type, 10 cases), type IV (collapsed type, 12 cases). The accuracy rate of CT was 100% (45/45). The misclassification rate of X-ray was 15.6% (7/45) and the missed diagnosis rate was 11.1% (5/45). CONCLUSIONS: CT examination could accurately diagnose Die-punch fracture and perform preoperative image classification.
