INTRODUCTION: Pronator syndrome has classically required open surgery that leaves a large scar; initial endoscopic techniques required approaches of an average 4cm without achieving release of all structures. The purpose of this study was to describe a new endoscopic approach that allows the median nerve to be safely and completely decompressed, leaving a smaller and less visible scar.
METHODS: Description of a new approach for decompression of the median nerve in the proximal third of the forearm with minimal incision and endoscopic technique in cryopreserved cadaveric specimens, describing incision, endoscopic anatomy, safe corridors and decompression sites.
RESULTS: In 20 elbows of cadavers, an endoscopic approach of the median nerve in the proximal forearm with a 4mm endoscope and 0° of angulation was performed. The advantages and limitations of the technique and surgical details are presented for release in the most common compression points of the nerve in the forearm. We performed this technique in 3 patients with good results without complications.
DISCUSSION: Release of the median nerve and section of potential aponeurotic compression structures by endoscopy is possible. The ulnar head of the pronator and the aponeurotic arch of the flexor digitorum superficialis are frequently implicated in the syndrome. The scar is aesthetically good. It is a relatively new technique, with lower morbidity that allows faster recovery of patients.
CONCLUSIONS: It is possible to perform a complete decompression of the median nerve in the forearm using an endoscopic approach, safely with lower comorbidity for the patient.
