Definition/Description[edit | edit source]
Wartenberg’s sign or Wartenberg syndrome is an entrapment of the superficial branch of the radial nerve. It is similar to radial tunnel syndrome, but in radial tunnel syndrome there is a problem with a larger part of the radial nerve. In Wartenberg’s there’s an isolated injury of the superficial sensory branch. The condition is also known as hand cuff neuropathy or neuropraxia. The term wristlet watch syndrome or watch-strap nerve compression is also used. But the common name is named after Wartenburg who discovered the condition. Wartenberg himself suggested the name cheiralgia paraesthetica.

Epidemiology /Etiology[edit | edit source]
This entrapment is caused by compression of the brachioradialis tendon and the extensor carpi radialis longus tendon in pronation of the hand. This compression can also occur during ulnar deviation of the wrist. As the superficial branch of the radial nerve emerges from beneath the brachioradialis and further trough the fascia that binds the brachioradialis tendon to the extensor carpi radialis longus tendon. this eventually leads to an inflammation of the superficial branch of the radial nerve.
The definition tells us that Wartenberg’s is a neuropraxia. This means that the axon is intact and the injury is incomplete. There will be a conduction block or a conduction slowing, this is due to segmental demyelination or ischemia. The nerve recovers when it is remyelinated, which happens spontaneously an relatively fast.
This entrapment can be caused by anatomic variations or overuse in these muscles. Other risk factors can also be included. These can be trauma, diabetes, repeated exposure to severe cold, over exertion of the hand, to tightly worn wrist watches, de Quervain’s disease, handcuffs ,lipoma, operations, tight fascial bands, a tight plaster or dressing and scar entrapment after previous operation.
In sports, wartenberg’s sign occurs in hockey, football and lacrosse. The conditions is responsible by direct trauma in these sports.
