[A disease pattern simulating a cubitocarpal "double-tunnel" syndrome due to anastomosis after Martin-Gruber
Abstract:
The article reports on a case which appeared as though two tunnel syndromes were present simultaneously, namely, the cubital and the carpal tunnel syndromes. Thorough electrophysiological examination revealed, however, that this simulated pattern was due to the presence of an anastomosis after Martin-Gruber. Three months after surgery the patient was free from symptoms. Intraoperative neurography had established the compression and its resolution. Anastomosis of Riche-Canieu was an additional, secondary finding.
