Article Synopsis
- The study aimed to assess the distances between upper arm nerves (radial, musculocutaneous, axillary) and a minimally invasive plate used in surgical procedures (MIPO) under various rotation angles.
- It involved ten upper extremities where a PHILOS plate was applied, and distances to the nerves were measured after creating a simulated fracture and adjusting for internal and external rotation.
- Results showed that distances from the radial nerve to the plate increased with external rotation and decreased with internal rotation, indicating that both the medial neurovascular bundle and the radial nerve are critical considerations during screw placement to avoid damage.
Background: The aim of our study was to project the A1-pulley of the thumb onto the total thumb length to enable its complete division with and without direct sight.
Materials And Methods: The study involved 50 hands from adult human cadavers. The proximal and distal borders of the A1-pulley were measured with reference to the first metacarpophalangeal joint (MCPJ).
Article Synopsis
- Posterior interosseous nerve (PIN) entrapment syndrome is a rare condition often caused by anatomical factors, with the Arcade of Frohse being the most common site of entrapment.
- The study involved dissection of 100 upper limbs to map the entrance and exit points of the PIN in relation to the supinator muscle and measure specific distances from the radial head.
- Results showed that the exit points of the PIN were predominantly muscular, indicating that about one-third of patients may experience additional entrapment at this site, which is important for surgical treatment considerations.
The aim of this study was to investigate the intersection point of the radial artery (RA) with Henry's approach. Ninety forearms from adult human cadavers which had been embalmed using Thiel's method underwent dissection. Henry's approach was performed alongside the whole length of the forearm, and the RAs course was investigated.

This study used a cadaveric model to evaluate the procedure from two entrance points with respect to hit ratio and possible complications, such as extraarticular extrusion of injection fluid. Ten heads, embalmed with Thiel's method, were investigated.

We aimed to define a safe zone for these approaches to avoid injury of the PIN and to evaluate their close and changing relationship to the nerve during forearm rotation.
Methods: The study collective consisted of 50 upper limbs.
A study was undertaken to examine the presence of the distal oblique bundle of the forearm in a large sample in order to describe its true prevalence. The study sample consisted of 200 cadaveric forearms. Fifteen were excluded due to defects in the distal interosseous membrane.
