Wrist X-Ray Normal Vs Colles' Fracture | AP & Lateral Views | Distal Radius, Dinner Fork Deformity

Support the channel on Patreon: patreon.com/drsamsimaginglibrary Wrist X-Ray Normal Vs Colles' Fracture | AP & Lateral Views | Distal Radius, Dinner Fork Deformity Colles' Fracture: Transverse fracture of the distal radius: The fracture line runs horizontally (at a right angle) to the length of the radius. Dorsal angulation of the distal fracture fragment. Dorsal displacement (posterior shift) of the distal fragment. "Dinner fork" or "silver fork" deformity: A classic dorsal curve visible on lateral view due to angulation and displacement. Comminution: Bone is broken into three or more fragments. Radial Inclination Angle: Angle between a line perpendicular to the longitudinal axis of the radius and a line connecting the radial styloid tip to the ulnar aspect of radius Normal: 21-25° Radial Inclination Angle in Colles' Fracture: Less than 15° indicates surgical management. Normal Radial Height: Vertical distance between the tip of the radial styloid, and the level of the distal ulnar articular surface (lunate fossa of the radius). Normal: 11–13 mm approximately Colles' Fracture: Reduced Radial Height: Radial shortening from impaction or collapse of the distal radius. Commonly less than 10 mm, and in severe cases may be less than 5 mm or nearly zero if uncorrected. Volar Tilt Angle: Normal Volar Tilt: Angle between a line perpendicular to the longitudinal axis of the radius and a line along the distal radial articular surface. Approximately 11° (range 10–15°) Colles' Fracture: Angle: Greater than 20° associated with unstable fractures. Pronator Quadratus Sign: The pronator quadratus muscle lies flat and sharply marginated over the distal radius. Pronator fat pad appears as a thin, linear soft tissue shadow anterior to the distal radius. Colles' Fracture: Obliteration, displacement, or bulging of this soft tissue line.
