Updates on and Controversies Related to Management of Radial Nerve Injuries

Radial nerve injuries are among the most common major traumatic peripheral nerve injuries. Recent literature has updated our knowledge of aspects ranging from radial nerve anatomy to treatment options. Observation and tendon transfers were, and still are, the mainstays of management. However, the improved outcomes of nerve repair even 5 months after injury have changed the treatment algorithm. Nerve repair techniques using conduits, wraps, autograft, and allograft allow tension-free coaptations to improve success. Nerve transfers have evolved to allow a more anatomic recovery of function if used in a timely manner. This review offers an update on radial nerve injuries that reflects recent advances.
