Wrist/forearm position while falling producing either a Colles’ fracture or Smith fracture. When there is a partial dorsal or volar fragment extending to the wrist joint in the sagittal plane then the fracture is termed a dorsal or volar Barton fracture respectively.

Radial styloid fracture. Assess and exclude potential scapholunate disruption
Non surgical with immobilization in a splint/cast for closed fractures that are:
Principles of fracture reduction and immobilization in cast/Plaster of Paris (POP).
Avoid extreme wrist flexion and ulnar deviation when positioning and molding a Colles’ fracture in POP, thereby preventing carpal tunnel syndrome (Cotton-Loder Position)
Plate and screw fixation
Closed distal complex radius fracture with wrist spanning external fixator
Superficial: Brachioradialis & flexor carpi radialis. Radial artery lies deep to brachioradialis in middle forearm and distally between brachioradialis and flexor carpi radialis. Superficial Radial nerve lies under brachioradialis.
Deep dissection: Middle third lateral border of pronator teres. Distal third lies flexor pollicis longus & pronator quadratus. Classic Henry approach is between brachioradialis and radial artery or modified Henry approach between radial artery and flexor carpi radialis. The radial artery is retracted laterally while flexor carpi radialis is retracted medially. With flexor pollicis longus also retracted medially pronator quadratus is exposed.
Anterior (Henry) approach to distal radius shaft. Release Brachioradialis at radius styloid process and make radial incision over pronator quadratus.
