Palpation of the Posterior Interosseous Nerve in the Forearm
The posterior interosseous nerve and its relationship to the forearm and lateral elbow pain is an important differential diagnosis in the NeuroCentric Approach ™. Conservatively speaking in diagnosis and treatment, it’s vital to accurately be able to palpate an entrapment site of the radial nerve. Therefore knowing the nerve location bases on surgically anatomy research and being able to provide mechanical stress to the nerve with palpation is an extremely important aspect of the exam.
During surgical interventions, it’s important to know the radial nerves’ location bases on superficial landmarks, typical branching patterns, and variations of those branching patterns. Otherwise, significant nerve injury can result.
The interphalangeal joint (IPJ) of the thumb is a helpful clinical tool in finding the Arcade of Frohse and the exit point of the deep radial nerve. Using the IPJ one can accurately and quickly find the relative location of the common entrapment sites of the posterior interosseous nerve and apply an intervention if needed using the Clinical Audit Process with the NeuroCentric Approach (TM).
