Methods: A total of 28 cases of thoracic trauma, X-ray film cannot be clearly diagnosed or can confirm the diagnosis but the need for further identification of forensic diagnosis of cases of DTS scan and three-dimensional reconstruction in order to control the study. Results: 1. The reconstructed images after DTS scanning showed that the knee joint fractures were clearly diagnosed, and the detection rate of 28 knee joint fractures was 92.86%. 2. DTS scanning could clearly detect the fresh knee joint fracture's fracture line, corresponding line and broken bones. For the old fracture, DTS scanning could clearly show the condition of the fracture end's healing. Conclusions: The technique is of great value in the diagnosis of knee joint fracture, especially in the examination of complex structure, thick body and review of internal fixation after fracture.展开更多

The purpose of this study was to quantitatively analyze joint space narrowing by measuring 2 new variables： the average joint space width （aJSW） and the articulate angle （AA） on X-ray films, and to evaluate the relationship between the 2 variables, knee function and OA symptoms. Methods Using the web-based radiology viewer （Cedara I-ReachTM 4.1.1）, we measured the 2 variables in 50 knees of 41 patients with knee OA participating in the Shanghai OA Study. We also evaluated the Kellgren-Lawrence （K-L） grade, the Western Ontario and McMaster Universities OA Index （WOMAC）, and additional questionnaire in OA knees. The study was approved by the ethics committee of Shanghai Ninth People＇s Hospital （No. 2009-28）. Results The aJSW correlated with the K-L grade （r=-0.57, P 〈0.001）, kneeling （r=-0.29, P=0.04）, sitting cross-legged on the floor （r=-0.31, P=0.03）, WOMAC pain （r=-0.31, P=0.03）, WOMAC disability （r=-0.35, P=0.01）, pain while squatting （r=-0.37, P=0.01）, and defecating in a squatting position （r=-0.39, P= 0.01）. The AA correlated with defecating in a squatting position （r=0.29, P=0.05）, WOMAC disability （r=0.30, P=0.04） and K-L grade （r=0.44, P=0.003）. The K-L grade also correlated with pain while squatting （r=-0.40, P=0.005） and defecating in a squatting position （r=-0.34, P=0.02）, WOMAC pain （r=0.30, P=0.04）, and WOMAC disability （r=0.30, P=0.04）. Conclusions The aJSW closely correlated with knee OA symptoms and function scores, and was more sensitive to knee OA related disabilities than K-L grade and the AA. The aJSW could be used as a new variable for knee OA evaluation.展开更多
