Ultrasonographyund-guided Thread- Release of the Arcade of Frohse: A Cadaveric Study

Purpose or Learning Objective: The objective of this study was To develop a minimally- invasive ultrasonography (US)und-guided thread-release technique for decompressing the posterior interosseous nerve by transecting the arcade of Frohse in anatomical specimens and to evaluate the procedure for effectiveness and safety.

Methods or Background: Radial tunnel syndrome is a rare, painful, and disabling compressive neuropathy in the proximal forearm, occurring due to the thickening of the posterior interosseous nerve at the arcade of Frohse. If conservative management fails, surgery is required. USltrasound-guided thread- release is a promising new, effective, minimally invasive technique for treating different peripheral nerve compression syndromes. In this study, we prospectively performed minimally invasive USultrasound-guided thread releases on the posterior interosseous nerve by transecting the arcade of Frohse on fresh cadaveric arms. Subsequently, The specimens were subsequently dissected and assessed regarding the efficacy and safety of the procedure. USltrasound visibility, degree of transection, and damage to adjacent structures were documented.

Results or Findings: Out Of 15fifteen interventions, a complete transection was achieved in 12twelve cases. Minimal damage to the supinator muscle and the superficial extensor muscle was unavoidable in four cases. Neurovascular structures were not harmed. USltrasound visibility was sufficient in all cases.

Conclusion: USltrasound-guided minimally invasive thread transection of the arcade of Frohse is a reliable and effective procedure for posterior interosseous nerve release in anatomical specimens.
