[The median nerve and phlegmons of the digito-carpal sheathes].

While it might seem that compression of the median nerve would be frequent during the course of digitocarpal phlegmonous tenosynovitis, involvement of this nerve under these circumstances is rarely mentioned in the literature. We recently observed two cases of phlegmonous tenosynovitis of the digitocarpal sheath associated with signs of nerve deficits in the territory of the median nerve. This led us to speculate why this phenomenon was so rarely encountered as well as the exact significance of this condition. We believe that the exact place of this association might be situated somewhere between an acute carpal tunnel and a compartment syndrome of the anterior loge of the forearm. An attempt at the description of the semiology of this association is made.
