Median Nerve Compression by the Ligament of Struthers: Clinical Image.

Median Nerve Compression by the Ligament of Struthers: Clinical Image.

In case of weakness of finger flexors and/or persistence of symptoms after carpal tunnel release, a more proximal compression site of the median nerve should be considered. In this report we present a case of compression by a ligament of Struthers. It was detected with ultrasound, which showed a clear thickening of the nerve at the site of a bony spur on the humerus, which was confirmed with magnetic resonance imaging. Surgical decompression resulted in partial recovery of weakness. This case shows the added value of ultrasound in the detection of more proximal median nerve compression such as a ligament of Struthers.
