Ultrasound-guided minimally invasive cubital tunnel thread release: An experimental study.

INTRODUCTION

Cubital Tunnel Syndrome is characterized by the compression of the ulnar nerve in the cubital tunnel and can cause restrictions to the activities of daily living. Traditional treatment includes conservative methods and, in more severe cases, different types of surgery. In these cases, common side effects of surgery may limit the clinical success. A new alternative could be a minimally invasive Ultrasound-guided (US-guided) thread release of cubital tunnel retinaculum also known as the Osborne's ligament. The aim of this study was to assess the efficacy and safety of ultrasound-guided thread cubital tunnel release (TCuTR) in an anatomical specimen model.

METHODS

In this single-center prospective experimental study, US-guided thread cubital tunnel release (TCuTR) was performed on 11 softly embalmed anatomic specimens. Subsequently, the elbows were dissected to assess the transection of Osborne's ligament and potential damage to adjacent structures.

RESULTS

Due to calcification, one specimen was ineligible for the intervention. In all remaining ten interventions, Osborne's ligament (OL) was completely transected, without any damage to the surrounding nerves, blood vessels, tendons, or muscles.

CONCLUSION

US-guided decompression has demonstrated a high success rate in transecting Osborne's ligament while averting damage to neighboring structures. This emerging technique appears to present an efficient and secure alternative to existing procedures.
