Endoscopically assisted nerve decompression of rare nerve compression and constriction syndromes at the upper extremity


Séance du lundi 06 mai 2013 (URGENCES CHIRURGICALES (14th Congrès ECTES) European Congress of Trauma and Emergency Surgery)


AbstractState of the art: Besides carpal tunnel and cubital tunnel syndrome, other nerve compression or constriction syndromes exist at the upper extremity. These include the compression of the proximal radial nerve (supinator syndrome), the proximal median nerve (pronator teres syndrome) and the anterior interosseus nerve (Kiloh–Nevin syndrome). This study was performed to evaluate our initial experience with endoscopically assisted decompression.Materials and methods: Between January 2011 and March 2012, six patients were endoscopically operated for rare compression or hour-glass-like constriction syndrome. This included eight decompressions: four proximal radial nerve decompressions, and two combined proximal median nerve and anterior interosseus nerve decompressions. Surgical technique and functional outcomes are presented.Results: There were no intraoperative complications in the series. Endoscopy allowed both identifying and removing all the compressive structures. In one case, the proximal radial neuropathy developed for 10 years without therapy and a massive hour-glass nerve constriction was observed intraoperatively which led us to perform a concurrent complementary tendon transfer to improve fingers and thumb extension. Excellent results were achieved according to the modified Roles and Maudsley classification in five out of six cases. Conclusion: Endoscopically assisted decompression in rare compression syndrome of the upper extremity is highly appreciated by patients and provides excellent functional results. This minimally invasive surgical technique will likely be further described in future clinical studies.
