Wrist drop in an arcade dancing game: unusual sudden bilateral radial palsy


Bilateral radial palsy is an uncommon clinical presentation, and the few cases reported in the literature are due to compressive injuries, such as in the use of axillary crutch [1] or birthing bar during labour [2]. Non-compressive demyelinated inflammatory mononeuropathy has been reported [3] but it is not of sudden onset nor does it present bilaterally simultaneously. One of the largest series of radial palsy describes 103 cases of which only 3 were bilateral: one was a bilateral sleep palsy, one was a mononeuropathy multiplex associated to HIV infection and the third was entrapment in the supinator channel associated with neuropathy of unclear origin [4].
