Article Synopsis
- The study aimed to assess the course and positioning of the extensor pollicis longus (EPL) tendon in relation to nearby structures and its clinical importance in different functional positions.
- Twenty human cadaver arms were examined to measure the EPL tendon’s movement, its wrapping angle around Lister’s tubercle, and its path near other tendons.
- The results indicated significant tendon mobility, highlighting the importance of understanding its anatomy for better diagnosis and surgical treatment of wrist injuries.
Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be useful in treating exsanguinating trauma patients. This study seeks to compare rates of success, complications and time required for vascular access between ultrasound-guidance and surgical cut-down for femoral sheath insertion as a prospective observational case control study. Participating clinicians from either trauma surgery or anesthesiology were allocated to surgical cut-down or percutaneous ultrasound-guided puncture on a 1:1 ratio.

In addition, to investigate whether there are differences between participants in terms of different levels of training.
Methods: A sample of 36 orthopedic trauma and anesthesiology assistant doctors, specialists, and senior physician was recruited from the emergency room management at a level I trauma center in Graz, Austria.
Article Synopsis
- The study aimed to determine the projected location of the musculocutaneous nerve (MCN) entry point into the coracobrachialis muscle relative to the length of the humerus.
- Sixty-six upper extremities were analyzed to measure distances between anatomical landmarks such as the greater tubercle (GT) and the medial and lateral epicondyles, which helped establish proportions for localization.
- Findings indicated that the MCN entry point is typically located between 14.9-33.9% of the humeral length from the GT, and 14.2-34.4% from the coracoid process, providing useful intervals for surgical procedures.
Article Synopsis
- The study focuses on developing a minimally invasive surgery technique for fixing specific arm fractures while analyzing the positions of important nerves near the surgery site.
- It involved using a 3.5 mm Locking Compression Plate (LCP) on 20 human upper extremities with careful nerve mapping and incision procedures.
- Results indicate that nerves are positioned safely with respect to the plate, suggesting the technique is effective for treating these types of fractures.
