Objective:To compare the efficacy of computed tomography(CT)and comventional X-ray plain film in assessing hip joint trauma.Methods:76 patients with hip joint trauma were studied by CT and X-ray plain film.The efficacy of CT and X-ray plain film in assessing the acetabular fracture,femoral head and neck fracture,intra-articular loose bone fragment,dislocation of hip joint,and para-articular soft tissue injuries was evaluated and compared.Results:CT was superior to X-ray plain film in demonstrating acetabular fracture,femoral head fracture and intraarticular loose bone fragment.CT was also effectively in revealing of intra-articular effusion and hemorrhage,paraarticular soft swelling.Conclusion:CT was a necessary way to evaluated hip joint trauma,and was more effective than X-ray plain film in diagnosis of hip joint trauma.

The clinical parameters of 1 000 patients undergoing spinal aesthesia were recorded and analyzed.Hypotension fulfilling the predefined criteria occurred in 173 patients.The logistic regression analysis revealed that the regression coefficients of height,weight and amount of fluid infusion during anesthesia were negative while those of age,emergency operation,hypertension/hypotension,heart disease,American Society of Anesthesiologists score,use of sedative drugs and sensory blocking level of anesthesia positive.The area of receiver operating characteristic was 0.905.This study contributes to the identification of patients with high risks for hypotension after spinal induction.
