Three rare cases of two-level skier's thumb injuries-review of the literature, anatomical variants and surgical treatment.

We report three rare cases of two-level skier's thumb injuries and explain the diagnostic challenges, surgical treatments, and anatomical explanations to emphasize the importance of a systematic diagnostic approach in every skier's thumb injury, including clinical examination, radiography, and ultrasonography. A surgical method to treat these rare cases is presented.

[Ulnocarpal Wrist Pain - Tips for the Daily Practice].

Ulnar wrist pain is a frequent symptom with many possible traumatic and non-traumatic causes. The complex anatomy and biomechanics of the wrist with the ulnocarpal complex including the triangular fibrocartilaginous complex (TFCC), the distal radio-ulnar joint (DRUJ) and the ulnar carpal bones make the differentiation between the possible causes difficult. A precise clinical investigation and appropriate imaging studies are essential for detecting the most important differential diagnoses, the first therapeutical steps and an early and appropriate referral to the hand surgeon.

Which Potential Linguistic Challenges do Pre-Service Teachers Identify in a Mathematical Expository Text?

Language is a crucial aspect of mathematical thinking and learning, and it is therefore essential for teachers to be equipped with the skills required for linguistically responsive teaching. This includes the ability to identify potential linguistic challenges in expository texts. In the present study, we investigated the ability of pre-service teachers ( = 115) to identify potential linguistic challenges in a mathematical expository text for ninth graders.

Extended liver resection including hypertrophy concept with portal venous embolisation for giant haemangioma. Too much surgery?

Haemangiomas of the liver are benign tumours, which are often diagnosed randomly. With an increase in size haemangiomas could become symptomatic. In this case therapeutic options, surgical or interventional, have to be weighted to a conservative approach.

[Intraoperative fluorescence angiography and cholangiography with indocyanine green in hepatobiliary surgery].

Intraoperative fluorescence angiography and cholangiography with indocyanine green (ICG) are increasingly used in routine hepatobiliary surgery. Its usage is manifold. It improves and facilitates navigation especially in minimal invasive and robotic surgery and therefore increases the safety of the surgical intervention.
