"Martin-Gruber anastomosis: between the median nerve or anterior interosseous branch and ulnar nerve, in the forearm"
"Marinacci anastomosis: a reverse Martin-Gruber anastomosis, between the ulnar nerve and median nerve"
"Berrettini anastomosis: between digital sensory nerve of ulnar and median nerves"
"History and etymology"
"Clinically, the Riche-Cannieu anastomosis is infrequently of significance, although its presence can confound nerve conduction study interpretations 2,4. However, there are rare instances of 'complete' Riche-Cannieu anastomoses of greater clinical significance, whereby the thenar muscles can be completely innervated by the ulnar nerve, which, for example, can lead to median neuropathy at the wrist having a milder than expected clinical presentation but a severe neuro-electrophysiological phenotype on nerve conduction studies 2,4."
