“…Our findings are consistent with this parameter. Other authors report the distance to the emergence of the PIN from the radius head, hence [D1] these measurements cannot be compared with our findings (Hazani et al, 2008;Hohenberger et al, 2020).…”

“…In this study we propose the division pattern of the PIN into two types, based on the emergence from the distal edge of the supinator muscle as the reference point. Extrapolating the findings of previous studies to this classification, Hohenberger et al (2020), informed a type I division in 18 % and type II division in 82 % of the evaluated specimens. However, they did not quantitatively assess the location of the PIN division.…”

“…There are five potential entrapment zones for the PIN, which are presented from proximal to distal in the following order: The fibrous fascial bands at the radial head, the radial recurrent vessels known as «Leash of Henry» at the radial neck, the fibrous edge of the extensor carpi radialis brevis muscle, the entrance point of the DBRN into the supinator muscle known as "Arcade of Frohse" and the distal edge of the supinator muscle (Sigamoney et al, 2017;Hohenberger et al, 2020). The "Arcade of Frohse" is considered the most frequent entrapment site (Spinner, 1968;Lister et al, 1979;Özkan et al, 1999;Ozturk et al, 2005).…”

The deep branch of the radial nerve (DBRN) runs through the radial tunnel, which is a muscle-aponeurotic structure that extends from the humeral lateral epicondyle to the distal margin of the supinator muscle (SM). The Posterior Interosseous Nerve (PIN) originates as a direct continuation of the DBRN as it emerges from the SM and supplies most of the muscles of the posterior compartment of the forearm. The PIN can be affected by compressive neuropathies, especially at the "Arcade of Frohse". Its preservation is of special interest in surgical approaches to proximal radius fractures and in compressive syndromes release, for which surgeons must have an adequate anatomical knowledge of its course. This descriptive cross-sectional study evaluated 40 upper limbs of fresh cadavers. The diameters of the DBRN, the length of the radial tunnel, and the distances to the supinator arch, PIN emergence and PIN bifurcation were measured. The deep branch of the radial nerve (DBRN) has a course of 23.8 ± 3.7 mm from its origin to the supinator arch, presenting a diameter of 2.2 ± 0.3 mm at that level. The length of the radial tunnel was 42.2 ± 4 mm. The PIN originated 70.7 ± 3.5 mm distal to the lateral epicondyle. Type I corresponds to the division of the PIN during its journey through the radial tunnel, presenting in 35 % of cases, and Type II corresponds to the division of the PIN distal to its emergence from the radial tunnel presenting in the remaining 65 %. This study enriches the knowledge of the PIN and provides useful reference information on a Latin American mestizo sample. We propose the division pattern of the PIN into two types. Future studies may use this classification not only as a qualitative variable, but also include quantitative morphometric measurements.

“…The fifth point is the distal border of the supinator. This was reported to be muscular in 65% of cadavers and tendinous in 35% [ 46 ]. Gilan et al found that the distal edge of the supinator was muscular in 57.5%, musculotendinous in 32.5%, and tendinous in 10% (Fig.…”

Radial nerve compression: anatomical perspective and clinical consequences

et al. 2023

View full text Add to dashboard Cite

The radial nerve is the biggest branch of the posterior cord of the brachial plexus and one of its five terminal branches. Entrapment of the radial nerve at the elbow is the third most common compressive neuropathy of the upper limb after carpal tunnel and cubital tunnel syndromes. Because the incidence is relatively low and many agents can compress it along its whole course, entrapment of the radial nerve or its branches can pose a considerable clinical challenge. Several of these agents are related to normal or variant anatomy. The most common of the compressive neuropathies related to the radial nerve is the posterior interosseus nerve syndrome. Appropriate treatment requires familiarity with the anatomical traits influencing the presenting symptoms and the related prognoses. The aim of this study is to describe the compressive neuropathies of the radial nerve, emphasizing the anatomical perspective and highlighting the traps awaiting physicians evaluating these entrapments.

RESUMEN:El nervio interóseo posterior (NIP) ha sido utilizado como sinónimo ocontinuación inmediata del ramo profundo del nervio radial (RPNR) al emerger en el compartimiento posterior del antebrazo. Su origen tampoco es claro, describiéndose como nervio interóseo posterior a su trayecto proximal, intermedio o distal al músculo supinador. El objetivo de esta revisión es detallar la visión de diversos autores respecto al origen y trayecto del NIP, proponiendo una correcta terminología para estas estructuras. Se realizó una revisión bibliográfica de varios textos y de algunos artículos utilizados para la enseñanza de la anatomía humana, publicados entre los años 1800 y la actualidad. En la búsqueda, se determinaron criterios de inclusión que consideraban, anatomía humana, escritos en español, francés o inglés y que aludieran al NIP. Tras la exploración inicial se localizaron 18 libros, procedentes de Francia,
