Anatomical Attributes Ascribing Radial Tunnel Syndrome

Introduction: The elbow is the most common site of compression, for the Ulnar nerve on the medial side aroundcubital tunnel & Radial nerve on its lateral side around the radial tunnel . Early diagnosis and treatment of radialneuropathy can significantly influence prognosis. There are limited studies of incidence and prevalence rates forulnar neuropathy. our study compares the morphological features of structures like arcade of Frohse ,Extensorcarpi radialis brevis ,leash of Henry around the tunnel on both the limbs with the clinical correlation.and highlights the role of the anatomical review before surgical management for patients with this conditionMethodology: 42 formalin fixed upper limbs were dissected and morphological features of arcade of frohse,distal edge of supinator, extensor carpi radialis brevis& leash of henry around radial tunnel were noted.Results: among the 42 upper limbs dissected right upper limb showed 57% tendinous ,24% membranous, & 10%muscular compared to 48% muscular, 25% membranous & 14% tendinous type of arcade of Frohse in left upperlimb. The distal supinator edge was fibrous in 71% & 59.5% of right & left upper limb respectively. also, radialrecurrent artery running above in almost all limbs irrespective of the side.Conclusion: The sensory-motor activity of the entire dorsal upper limb could be affected by an unusual Radialnerve relationship with its neighboring structures around Radial tunnel. knowledge of the anatomical variationsaround the radial tunnel therefore important for Surgeons & Radiologists to consider the nature of Radial nerveneuropathy-related complications.
