Resumen
Este resumen es generado por máquina.La rama del pronador cuadrado (PQB) del nervio interósseo anterior (AIN) está constantemente presente y puede transferirse al nervio interósseo posterior (PIN) sin tensión, ofreciendo una opción quirúrgica viable.
Área De La Ciencia
- La anatomía
- Innovación quirúrgica
- La neurociencia
Sus Antecedentes
- El nervio interósseo anterior (AIN) y el nervio interósseo posterior (PIN) son cruciales para la función del antebrazo y la mano.
- Comprender las variaciones anatómicas es vital para los procedimientos de transferencia de nervios.
- La rama del pronador cuadrado (PQB) es un donante potencial para la reconstrucción del nervio.
Objetivo Del Estudio
- Evaluar las características anatómicas y las variaciones del NIA.
- Para determinar la viabilidad de transferir el PQB al PIN sin tensión.
Principales Métodos
- La disección de 50 extremidades superiores de 25 cadáveres de hombres adultos.
- Examen detallado del origen y los patrones de ramificación del AIN y del PIN.
- Evaluación de la presencia del PQB y su transferibilidad al PIN.
Principales Resultados
- El AIN se originó en el nervio mediano a un promedio de 5,2 cm distal de la línea intercondilárea.
- Se observaron variaciones en el origen de AIN de los fasciculos nerviosos medianos; se encontraron dos AIN en 2 muestras.
- El PQB estaba constantemente presente en todos los antebrazos diseccionados, con variaciones solo en el diámetro.
Conclusiones
- El PQB está presente de forma fiable y es adecuado para la transferencia de nervios.
- La transferencia del PQB al PIN es factible sin tensión, incluso con todo el rango de movimiento del antebrazo.

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
