Core Tip
Core Tip: Compression of the median nerve beneath the lacertus fibrosus is an increasingly recognized but frequently underdiagnosed cause of proximal median nerve dysfunction. This cadaveric study demonstrates the anatomical feasibility of Nanoscope-assisted lacertus fibrosus release under direct visualization. Systematic post-procedural open dissection confirmed complete release and preservation of adjacent neurovascular structures in all specimens. By combining minimally invasive access with continuous visualization of critical anatomy, the Nanoscope-assisted approach represents a technically viable strategy for proximal median nerve decompression and provides an anatomical foundation for prospective clinical evaluation.
