“…There are 3 types of radial neuropathy, according to the level of injury : PIN palsy, SRN palsy, and combined6,8,9,10). The PIN is most vulnerable to entrapment just beyond its origin as it passes beneath the arcade of Frohse at the proximal edge of the supinator in the radial tunnel9).…”

“…The PIN is most vulnerable to entrapment just beyond its origin as it passes beneath the arcade of Frohse at the proximal edge of the supinator in the radial tunnel9). Compression of the PIN alone may manifest as pure motor weakness in its distribution, resulting in the inability to extend the metacarpophalangeal joints of the finger and thumb, as well as weakness in extending the thumb at the interphalangeal joint, which is also called "finger drop."…”

“…Normal sensory nerve action potential (SNAP) values include an amplitude of ≥15 µV, a peak distal latency of ≤2.8 ms, and a velocity of ≥50 m/s9). The SNAP may be abnormal in cases of SRN and normal in PIN neuropathy with unaffected SRN or a herniated cervical disk and other diseases.…”

ObjectivePosture-induced radial neuropathy, known as Saturday night palsy, occurs because of compression of the radial nerve. The clinical symptoms of radial neuropathy are similar to stroke or a herniated cervical disk, which makes it difficult to diagnose and sometimes leads to inappropriate evaluations. The purpose of our study was to establish the clinical characteristics and diagnostic assessment of compressive radial neuropathy.MethodsRetrospectively, we reviewed neurophysiologic studies on 25 patients diagnosed with radial nerve palsy, who experienced wrist drop after maintaining a certain posture for an extended period. The neurologic presentations, clinical prognosis, and electrophysiology of the patients were obtained from medical records.ResultsSubjects were 19 males and 6 females. The median age at diagnosis was 46 years. The right arm was affected in 13 patients and the left arm in 12 patients. The condition was induced by sleeping with the arms hanging over the armrest of a chair because of drunkenness, sleeping while bending the arm under the pillow, during drinking, and unknown. The most common clinical presentation was a wrist drop and paresthesia on the dorsum of the 1st to 3rd fingers. Improvement began after a mean of 2.4 weeks. Electrophysiologic evaluation was performed after 2 weeks that revealed delayed nerve conduction velocity in all patients.ConclusionWrist drop is an entrapment syndrome that has a good prognosis within several weeks. Awareness of its clinical characteristics and diagnostic assessment methods may help clinicians make diagnosis of radial neuropathy and exclude irrelevant evaluations.

“…Sixty upper limbs from 30 Turkish subjects (18 males and 12 females) were dissected to reveal the course of the PIN and to examine possible compression sites at the proximal and distal edges of the supinator muscle, and the exit of the nerve from the ECRB (Kirici & Irmak, 2004). An anatomic study of 45 supper limbs, from 40 cadavers, was performed to analyse the relations between the medial edge of the ECRB and the PIN and Laulan et al (1994) suggested that the ECRB is a possible cause of PIN entrapment.…”

Multiple Variations of Extensor Muscles of Forearm in Relation to the Radial Nerve: a Case Report and Review

et al. 2008

SUMMARY:During routine dissection in the Department of Anatomy, multiple variations of forearm muscles in relation to the radial nerve and its branches were observed on the right side of a 34 year old male cadaver. Brachioradialis close to its origin was receiving muscle fibers from the brachialis and the radial nerve was passing in between them. Extensor carpi radialis brevis was absent and the extensor carpi radialis longus was giving two tendons in the second compartment of extensor retinaculum before its insertion while passing deep to the abductor pollicis longus. Absence of extensor carpi radialis brevis can be explained with the arrangement in lower mammals, where the two extensores carpi radiales are represented by one muscle. Ontogeny repeats phylogeny and anatomical variations have developmental basis. Hence, the pattern of muscular arrangement in this case can be said to be less evolved than the usual arrangement. The course of radial nerve between the two heads of brachioradialis makes it highly vulnerable to compression and injury, which may manifest as wrist drop (radial nerve palsy) or radial tunnel syndrome (compression of posterior interosseous nerve).

MEDICINA y SEGURIDAD del trabajo Julio -septiembre 2010 Med Segur Trab (Internet) 2010 56 (220): 248-256 Neuropatía compresiva del nervio interoseo posterior a nivel del codo... Raúl Jesús Regal Ramos 248MEDICINA y SEGURIDAD del trabajo Introducción: La afectación compresiva del nervio radial se encuentra recogida en el último Listado de Enfermedades Profesionales (LEP), con el código 2F0601. En este apartado no se recoge entre las "principales actividades" capaces de producir afectación del n.radial la compresión de origen laboral más frecuente de este, el síndrome de la Arcada de Frohse (SAF).Objetivos: El objetivo de esta revisión no es solo reflejar que la afectación compresiva del nervio interóseo posterior puede considerarse una Enfermedad Profesional (EP), sino que además debería estar recogida en el actual listado de EP entre las "principales actividades capaces de producir afectación del nervio radial". Metodología: Se han revisado hasta Febrero de 2010 las siguientes bases de datos bibliográficas:Medline, Embase, Cochrane.Resultados: Esta revisión bibliográfica nos permite concluir que: El SAF puede tener un origen laboral (la fibrosis del supinador corto se relaciona con movimientos repetidos de pronación y supinación del antebrazo y esta descrita su mayor prevalencia en determinadas profesiones que realizan estos movimientos). El SAF es la neuropatía compresiva de origen laboral mas frecuente del nervio radial, la más relacionada con los movimientos repetitivos de la mano y antebrazo. La Arcada de Frohse es el lugar más frecuente de compresión del radial.Conclusiones: Por tanto, el SAF puede considerarse una EP, si asocia factores de riesgo laborales suficientes, y debería estar recogido en el LEP por tratarse de la localización más frecuente de compresión de origen laboral del nervio radial.
