![]() Fracture of distal growth plate of ulna, without disruption of DRUJ Fig. – Galeazzi-equivalent lesion : Variant of classic Galeazzi fracture in skeletally immature children and adolescents ( Fig. Dislocation of distal radio-ulnar joint (DRUJ) – Classic Galeazzi fracture : Unstable fracture-dislocation of forearm result inĢ. Pronation : Proximal end of disal radial fragment can only goes anteriorly as blocked by ulna posteriorly, so there is posterior displacement of distal radial head and dorsal dislocation of ulnaĭefinition and classification of Galeazzi fracture ![]() Supination : Anterior displacement of distal radial head and thus volar dislocation of ulnaĢ. – Depending on wrist’s position, the distal radial fragment rotates in opposite direction ( Fig. – Forceful axial loading on radius ( most commonly due to fall ) result in fracture of radius and radial shortening Brachioradialis : Pulls the distal radial fragment proximally Fig. Pronator quadratus : Rotational force on distal radiusĢ. – Muscles spasm following fracture contribute to further deformity and compromised closed reduction ( Fig. – Substantial shortening in fractured radius relative to ulna results in marked disruption of TFCC and therefore dislocation of DRUJ 3 – Triangular fibrocartilage complex (TFCC) Deep limb attaches to fovea of ulna and superficial limb attaches to styloid process of ulna Fig. Both deep and superficial limb attaches to junction of lunate fossa and sigmoid fossa of radiusĢ. – DRUJ is primarily stabilized by triangular fibrocartilage complex (TFCC) ( Fig. – Biomechanically, fractures of middle to distal third of radius more likely cause disruption of distal radioulnar joint instead of proximal radioulnar joint – Junction of distal and middle 1/3 of radius is thinnest and thus most prone to fracture ( Fig. – He presented such fracture pattern in largest number of case series with detailed description of management and pathomechanics behind, thus named after him 1 ), a very distinguished orthopedic surgeon in Italy Orthopedic pitfalls in the ED: Galeazzi and Monteggia fracture-dislocation.
