PIN (posterior interosseous nerve) syndrome is one of the compression neuropathies of the radial nerve near the elbow or in the forearm. This is an uncommon condition and very challenging to diagnose. Electromyography (EMG) and Nerve Conduction Studies (NCS) are commonly used in the evaluation of this syndrome. The other potential compression neuropathies in the area of the radial distal nerve are Radial Tunnel Syndrome.

Symptoms of Posterior Interosseous Nerve Syndrome –

Weakness in the fingers and thumb, especially elevating the fingers, fingers drop.

Testing for Posterior Interosseous Nerve Syndrome (PIN) –

After a careful clinical examination of the affected areas of your arm by your Doctor you may be prescribed an electrophysiological test such as:

• A Nerve Conduction Study to measure the nerve signals in your arm to ensure that the nerve is conducting the signal effectively. The Nerve Conduction Study is an important tool your doctor uses to see how severe your Posterior Interosseous Nerve Syndrome is and will help your treating doctor recommend the best course of treatment.
• Electromyogram (EMG) to measure the electrical activity in your muscles. This is to determine if you have suffered any nerve damage.

These studies may show denervation changes in the muscles innervated by the posterior interosseous nerve.
