Surgical Anatomy of the Distal Radius


Key Points

  • The precise knowledge of the evolution of the anatomy of the radius is essential to understand the main points of the treatment decision and the surgical principles.

  • General anatomy of the distal radius subdivides it in a diaphysis, metaphysis, and epiphysis. Each surface of different shape is covered by a different structure, mostly tendoninous. The angulations of the ulnar and the radial columns are different. The watershed line is the most distal limit that a standard osteosynthesis plate must not exceed.

  • The “radiographic check list” of the distal radius include:

    • radial inclination (frontal plain)

    • volar tilt

    • teardrop angle

    • AP distance

    • articular depth

    • dorsal rim line

    • coronal shift

Importance of the Problem

A distal radius fracture (DRF) is a very frequent pathology, involving 15% of women after age of 50 years, in relation with decrease of bone mineral density (85% low BMD, 51% osteoporosis). Development and innovation of not only the anatomy's comprehension, but also of the implants and approaches have considerably improved the function of these patients.

Current Opinion

Advanced knowledge of basic anatomy and individual variations are deemed mandatory for the anatomic reduction of distal radius fractures (mainly in case of comminution) as well as to obtain fracture fixation while “staying out of trouble,” hence avoiding iatrogenic tendinous/ligamentous injuries when anatomic principles are violated.
