Resumen
La inestabilidad de la articulación radioulnar distal (DRUJ) es el resultado de factores complejos que afectan la estabilidad de la articulación. Comprender sus causas, presentación e imágenes es crucial para el manejo efectivo de casos agudos y crónicos.
Área de la Ciencia:
- Cirugía ortopédica
- La anatomía
- Biomecánica
Sus antecedentes:
- La articulación radioulnar distal (DRUJ) es crítica para la rotación del antebrazo y la función de la muñeca.
- La inestabilidad de la DRUJ presenta un desafío clínico significativo debido a su compleja anatomía y dependencia de los tejidos blandos para la estabilidad.
Objetivo del estudio:
- Proporcionar una revisión exhaustiva de la inestabilidad de la articulación radioulnar distal (DRUJ).
- Para aclarar la anatomía, la cinemática, la etiología y los hallazgos de imágenes asociados con la inestabilidad de DRUJ.
- Para esbozar las estrategias actuales de manejo quirúrgico para la inestabilidad aguda y crónica de DRUJ.
Principales métodos:
- Revisión sistemática de la literatura centrada en la inestabilidad de DRUJ.
- Análisis de las estructuras anatómicas que contribuyen a la estabilidad de DRUJ.
- Revisión de las modalidades de diagnóstico por imágenes para la patología de DRUJ.
- Evaluación de las técnicas quirúrgicas para la inestabilidad de DRUJ.
Principales resultados:
- La estabilidad de DRUJ depende de las estructuras óseas, cóndricas y ligamentosas, que a menudo actúan en combinación.
- Varias etiologías contribuyen a la inestabilidad de DRUJ, lo que requiere un enfoque diagnóstico exhaustivo.
- La gestión eficaz requiere comprender los factores específicos que contribuyen a las presentaciones agudas y crónicas.
Conclusiones:
- Una comprensión completa de la anatomía y la biomecánica de DRUJ es esencial para diagnosticar y manejar la inestabilidad.
- La imagen precisa y la evaluación etiológica guían la selección de las intervenciones quirúrgicas adecuadas.
- Esta revisión sintetiza los conocimientos actuales para ayudar a los médicos a controlar la inestabilidad de DRUJ.

Bones of the Upper Limb: Ulna
2.6K
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...

Bones of the Upper Limb: Radius
2.6K
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.

Ankle Joint
1.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Spinal Nerves: Plexus I
1.3K
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.

Bones of the Upper Limb: Humerus
4.3K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Muscles that Move the Forearm
2.1K
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...
