Abstract
Objective The endoscopic release of the ulnar nerve reproduces a simple (in situ) procedure with smaller incisions, less soft tissue damage, and higher preservation
of nerve vascularization. Endoscopy allows the clear visualization of the entire path
of the nerve and surrounding noble structures. Moreover, it reveals any signs of compression
and allows a safe release of 10 cm distally or proximally to the medial epicondyle.
Methods A retrospective survey revealed that 15 subjects (1 with a bilateral injury) underwent
an ulnar nerve compression release at the elbow using the endoscopic technique with
Agee (Micro-Aire Sugical Instruments, Charlottesville, VA, EUA) equipment from January
2016 to January 2020.
Results Symptoms of ulnar nerve compression improved in all patients; on average, they resumed
their work activities in 26.5 days. There was no recurrence or need for another procedure.
In addition, there were no severe procedure-related complications, such as infection
and nerve or vascular injury. One patient had transient paresthesia of the sensory
branches to the forearm, with complete functional recovery in 8 weeks.
Conclusion Our study shows that the endoscopic release of the ulnar nerve at the elbow with
the Agee equipment is a safe, reliable technique with good outcomes.
