Anatomy of the distal forearm

A thorough knowledge of the anatomy around the wrist is essential. The following images give a short introduction.

Direct to the radial styloid

Dorsal approaches (as illustrated A-D) can be chosen between the different extensor compartments (as illustrated I-VI), as dictated by the specific fracture pattern.

Here an approach between the first and second extensor compartments (A) is described in detail.

Ulnar palmar

In general, there are two palmar surgical approaches to the distal radius– a modified Henry approach to the radius and a more ulnar approach, designed to expose the median nerve as well as the distal radius.

Dorsal approach

Dorsal approaches (as illustrated A-D) can be chosen between the different extensor compartments (as illustrated I-VI), as dictated by the specific fracture pattern. In this module the dorsal approach through the third extensor compartment (B) is described in detail.

Palmar approach

The modified Henry approach uses the plane between flexor carpi radialis tendon and the radial artery.

Ulnar approach

The ulnar shaft and the fracture gap between the ulnar styloid and the distal metaphysis are usually easily palpated.

A straight, longitudinal incision is made over the distal ulna, between the tendons of the extensor and flexor carpi ulnaris.

Dorsal approach

This extended dorsal approach can be used for wrist fusions or for joint-spanning plate fixation of comminuted intra-articular distal radius fractures.
