The symptoms of a radial tunnel syndrome
Radial tunnel syndrome, also known as posterior interosseous nerve syndrome, is a painful condition in the elbow area. It results from the compression of a branch of the radial nerve at the level of the supinator muscle, at the point where the forearm juts out to the elbow. Contact us to make an appointment

The symptoms of a radial tunnel syndrome
Radial tunnel syndrome, also known as posterior interosseous nerve syndrome, is a painful condition in the elbow area. It results from the compression of a branch of the radial nerve at the level of the supinator muscle, at the point where the forearm juts out to the elbow.
What are the symptoms?
The compression causes a sharp pain on the dorsal side of the elbow and forearm. This pain can appear suddenly or gradually, depending on the cause. It can be triggered or worsened by extension movements of the elbow and wrist. It is sometimes amplified at night, which has the consequence of affecting the quality of the patient’s sleep. When the compression is permanent, fatigue and loss of muscle strength can be observed.
The symptoms of radial tunnel syndrome are similar to those of lateral epicondylitis (Tennis elbow). It is not uncommon for the two conditions to coexist.
What are the most common causes?
The causes of compression are varied. They can be traumatic (following an injury), mechanical (a consequence of overwork or poor ergonomics) or medical (pressure exerted by a cyst, a bone tumor, lipomas or tissue inflammation of surrounding areas). Women are affected in a higher proportion than men.
How is it diagnosed?
The diagnosis is made by means of a clinical examination. An interview with the patient allows to specify the demographic profile, history of symptom, and family history. The evaluation of sensory signs is done by palpation. Certain challenge and resistance tests can be useful, in particular the Scratch Collapse Test. Ultrasound or electromyogram may be prescribed to deepen diagnose and detect the possible lesions.
