Osteoporotic Ankle Fracture / 대한족부족관절학회지

The incidence of osteoporotic ankle fractures is increasing as the population ages. These fractures are becoming more common in clinical practice and require careful management because of the higher likelihood of developing complications than typical ankle fractures.The introduction of a method for measuring the ankle joint bone mineral density is a valuable tool for assessing the bone quality of the ankle joint. By evaluating the bone mineral density, healthcare professionals can better understand the extent of osteoporosis and the overall strength of the ankle joint. This information is crucial for determining the appropriate treatment for individual fractures. Several factors must be considered when deciding on the treatment for osteoporotic ankle fractures. These include the ankle joint bone mineral density, skin condition, any comorbidities the patient may have, and the patient's functional demands. Taking these factors into consideration allows healthcare providers to tailor the treatment plan to the specific needs and the circumstances of each patient. By applying the appropriate treatment, it is expected that the complications associated with osteoporotic ankle fractures can be minimized, and the prognosis for patients can be improved.

Ultrasound-guided transhepatic computed tomography cholecystography in beagle dogs

This study was performed to evaluate the feasibility of ultrasound-guided computed tomography (CT) cholecystography and to establish an optimal protocol. In 8 healthy beagles, CT cholecystography was conducted using four contrast formulas; two dilution ratios (1:1 vs. 1:3) and two total volumes (8 mL vs. 16 mL) of 300 mgI/kg iohexol after ultrasound-guided percutaneous contrast injection into the gallbladder. CT images were obtained at 3, 10, and 30 min after injection and assessed qualitatively and quantitatively. For all contrast formulas, CT cholecystography showed the gallbladder and the intra- and extrahepatic bile ducts. The volume of the gallbladder and size of bile duct were significantly larger when using a volume of 16 mL iohexol than an 8 mL volume regardless of the dilution ratio. The distinction between the common bile duct and duodenum, the filling of the gallbladder, and the patency of bile duct were effectively assessed using a 16 mL volume of contrast agent with either dilution ratio. Beam-hardening artifacts deteriorated CT image quality for visualizing the biliary system when using the dilution ratio of 1:1. Patency of the bile tract could be easily evaluated using a curvilinear planar reconstruction. There was no significant difference in CT scan time among the different conditions. Minor leakage of contrast agent temporarily occurred after contrast injection in 30% of 32 sets of CT cholecystography. Ultrasound-guided percutaneous cholecystography can visualize both gallbladder and biliary tract with minimal artifacts using a contrast agent volume of 16 mL with a 1:3 dilution ratio.
