A Cadaveric Study on Posterior Interosseous Nerve for Radial Tunnel Syndrome
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Radial tunnel syndrome is characterized by pain along the course of posterior interosseous nerve in the upper part of anterior aspect of forearm in the cubital fossa. But the diagnosis of radial tunnel syndrome is difficult because of its close association with lateral epicondylitis. In this study the course of posterior interosseous nerve is studied in 58 formalin fixed upper limb specimens by applying the Rule of Nine test and the results were noted. Out of 29 right upper limb specimens, the posterior interosseous nerve traversed through lateral column in 23 specimens and in middle column in 6 specimens. In the remaining 29 left upper limb specimens also the same results were noted. On conclusion the prevalence of orientation of posterior interosseous nerve is comparatively higher in lateral columns than the middle columns. Hence the knowledge of the course of posterior interosseous nerve helps the clinician to identify the exact site of tenderness in the radial tunnel syndrome.
