Background: Adolescent athletes are a high-risk population for stress fractures. We report four cases of stress fractures of the second proximal phalanx, which had not been previously diagnosed as the location of the stress fracture of the foot, in teenage athletes.
Case Report: All fractures were on the plantar side of the proximal phalangeal base, and the oblique images of the plain radiograph clearly depicted the fractures.
Article Synopsis
- - The study aimed to evaluate the accuracy of high-resolution ultrasound in diagnosing meniscal tears, using arthroscopic examination as the benchmark, and also looked into the areas of the meniscus that could be visualized with ultrasound after markers were placed in cadaveric knees.
- - A total of 70 patients underwent preoperative ultrasound assessments, with the results compared to surgical findings, revealing ultrasound's sensitivity of 88% and specificity of 85% for diagnosing meniscal tears, although certain tear types had lower sensitivity.
- - The research concluded that while ultrasound could be a useful screening tool for meniscal tears, its limitations, such as the inability to evaluate 10% of lateral menisci due to poor imaging, need to be addressed.*
Background: In recent years, double-bundle (anteromedial bundle [AMB], posterolateral bundle [PLB]) anterior cruciate ligament reconstruction has developed into an accepted practical surgical procedure; therefore, its efficacy needs to be established.
Hypothesis: Multiple-sliced 2-dimensional magnetic resonance imaging allows evaluation of each bundle separately. Both bundles are important for knee stability, and each bundle has a role in the prevention of knee instability.
