    ABSTRACT: Simultaneous ipsilateral hip and knee fracture-dislocations are orthopedic emergencies requiring immediate management. Delayed or inadequate treatment usually results in an extremely poor outcome. Reduction of the dislocated hip can be difficult because of the ipsilateral knee dislocation and instability. We report a case involving a 46-year-old man with simultaneous ipsilateral hip and knee fracture-dislocations. He underwent closed reduction for the knee fracture in the emergency department but required open reduction and internal fixation of the unstable hip fracture-dislocation with a distal femur skeletal traction pin under general anesthesia.

    ABSTRACT: Fat embolism syndrome (FES) is a potentially fatal complication of long bone fractures. There have been no reports of FES in long bone fractures in this decade in Taiwan. The purpose of this study was to review the FES experiences in a tertiary referral center between January 1997 and February 2008. Between January 1997 and February 2008, 13 patients with long bone fractures with documented FES in our institution were reviewed. FES was diagnosed clinically by at least 2 major criteria or 1 major with at least 4 minor signs of Gurd's criteria. The incidences of FES, less than those reported in the literature, were 0.15% in fracture of the tibia, 0.78% in fracture of the femur and 2.4% in multiple fractures. The mortality rate of FES, similar to other available results, was about 7.7%. All cases were less than 35 years old, except for 1 70-year-old male. Fat embolism occurred within an average of 48.5 hours after long bone fracture. Eleven presented with sudden drop in hemoglobin level, dropping 4.2 g/dL on average. Nine presented with thrombocytopenia, and 10 presented with sudden drop in platelet count, dropping 140,000/dL on average. Two had cerebral sequelae without recovery at the last 48-month follow-up. This 12-year interval retrospective study revealed modern epidemiologic results for FES in long bone fracture. Compared with the available literature in the recent decade, the incidence of FES in long bone fracture in our institution is less and the mortality rate is similar.

    ABSTRACT: OBJECTIVE: The objectives of this article are to, first, describe the reasons for and details of the MDCT protocol for patients with suspected renal hypertension; second, explain the importance of comprehensive evaluation by MDCT in patients with suspected renal hypertension; third, review the image appearances of important conditions that may be encountered in the reader's clinical practice; and, fourth, explain what information should be included in a comprehensive MDCT report for patients with suspected renal hypertension. CONCLUSION: MDCT is widely used for renal artery evaluation in patients with resistant hypertension. Because the regions outside the renal arteries might also have diseases that contribute to the symptoms, a comprehensive interpretation including the renal arteries, renal parenchyma, adrenal glands, and scanned abdomen is very important. The scanning parameters should be adjusted according to the patient's body habitus because some patients with suspected renal hypertension are children or young women. In this article, cases with illustrations showing the process from protocol to interpretation are provided.
