Case-control study on the clinical characteristics of senile-osteoporotic Colles fracture / 中国骨伤

<p><b>OBJECTIVE</b>To analysis and compare the clinical characteristics of Colles fractures between patients with osteoporotic and without osteoporotic.</p><p><b>METHODS</b>From June 2007 to June 2009, 260 patients with Colles fracture were reviewed, including 60 males and 200 females, with a mean age of 66.5 years old. According to Cooney classification: 44 patients were type I, 83 patients were type II, 92 patients were type III and 41 patients were type IV. Among the patients, 96 patients were osteoporotic Colles fractures, and 164 patients without osteoporotic. The general information, invalidiation rate and short-term clinical results were compared between two groups.</p><p><b>RESULTS</b>There were no statistically difference of age, gender and fracture position between the two groups. There were more patients with type III and type IV, and higher invalidiation rate in osteoporotic Colles fracture group compared to those of no osteoporotic Colles fracture group (P<0.01). At the 6 months after treatment, the clinical effects of no osteoporotic Colles fracture group was better than that of osteoporotic Colles fracture group (P<0.01).</p><p><b>CONCLUSION</b>The senile-osteoporotic Colles fracture has different clinical characteristics, which should be given special treatment, frequent review and communication between doctors and patients during the period of treatment.</p>

Role of MR contrast-enhanced fluid-attenuated inversion recovery imaging in the diagnosis of leptomeuingeal lesions / 中华放射学杂志

Objective To evaluate contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging in the detection of leptomeningeal lesions.Methods Seventeen patients with a variety of leptomeningeal lesions were analyzed.The MRI protocol included un-enhanced and contrast-enhanced FLAIR images and contrast-enhanced T_1WI,Comparisons between contrast-enhanced FLAIR images and T_1WI and between un-enhanced and contrast-enhanced FLAIR images were made to determine which sequence better depicted the lesions.Results Leptomeningeal lesions showed as either diffusely or locally abnormal hyper-intensity along sulci or cistern on three sequences.Comparison between contrast-enhanced FLAIR and T_1WI showed that only contrast-enhanced FLAIR revealed the abnormalities in 7,both revealed the abnormalities but the former was superior in 2 ,and both were conspicuous in 7. In 1 patient of tuberculous meningitis,diffuse abnormalities of sulci were shown only on contrast-enhanced FLAIR, abnormalities of cisterns were shown on both sequences but the former was superior.Comparison between un- enhanced and contrast-enhanced FLAIR showed that only contrast-enhanced FLAIR revealed the abnormalities in 9,both revealed the abnormalities but the former was superior in 3,and both were conspicuous in 4. In 1 patient of tuberculous meningitis,abnormalities of cisterns were shown only on contrast-enhanced FLAIR,diffuseabnormalities of sulci were shown on both sequences but the former was superior.Conclusions Contrast-enhanced FLAIR images were superior to un-enhanced FLAIR images and contrast-enhanced T_1WI in the detection of leptomeningeal lesions. Contrast-enhanced FLAIR images are helpful and should be considered when findings on un-enhanced FLAIR images and/or contrast-enhanced T,WI are inconclusive.
