Abstract

The fabella has been considered to have a minor clinical significance. However, there have been a few reports describing the fabella as one of the causes of peroneal nerve palsy (PNP). This report describes a 66-year-old farmer who complained of acute neurologic symptoms involving the fabella. Surgical extirpation was performed and neurologic function was recovered dramatically. Recently, there have been no published reports on fabella syndrome with common PNP. Here, we report an unusual case of common PNP with the fabella as a cause.
