Previous studies have described a segment of the axillary nerve (AN) that cannot be surgically explored through the deltopectoral and posterior surgical open approaches (blind zone). We present the first two cases using an endoscopic-assisted approach to explore the AN through a posterior approach. MATERIAL AND


Two patients were evaluated, in whom clinical, electrodiagnostic testing, and MRI could not localize the level of the AN dysfunction. An open posterior endoscopic-assisted (OPEA) approach was performed 4 and 9 months after injury in an attempt to visualize all segments of the AN. Photographs and videos were taken to evaluate the intraoperative visualization of the AN and provide long-term clinical follow-up.


Almost the entire AN was visualized with the scope through the OPEA approach, avoiding the deltopectoral approach. No AN lesion was found during the nerve exploration. A triceps branch to AN transfer, using the previous posterior approach, was performed. Patients in both groups achieved a deltoid muscle function of BMRC grade 4 after 24 and 9 months, respectively.


The exploration of the AN through the OPEA approach was a useful strategy to visualize the blind zone of the AN without requiring the addition of a deltopectoral approach. We believe this novel technique has a role in selected cases of AN injury.
