![]() ![]() When a case with no correlations between lateral epicondylitis degree in MRI and clinical symptoms, one should take the possibility of radial tunnel syndrome into consideration. This is a case diagnosed as lateral epicondylitis which showed no improvement under conservative treatment, but improved after a local anesthetic injection on the tender point. After the operation, the right arm pain was relieved. In the operative field, the most proximal part of the superficial head of the supinator muscle was tendinous and formed a fibrous arch, which was resected. So we decided that the symptoms were caused not by lateral epicondylitis but rather by radial tunnel sybdrome and an operation was performed. Axial STIR(short tau inversion recovery) image showed high signal intensity at the origin of the extensor carpi radialis brevis, which was so minimal that it was not comparable to clinical symptoms. Clinically, severe tender point over the forearm was relieved after a local anesthetic injection. A 39-year-old man was presented who had a 2.5-year history of right elbow and forearm pain which was unseccesfully treated as 'tennis elbow'. Radial tunnel syndrome is a rare disorder and it's symptoms sometimes so closely overlap those lateral epicondylitis, causing difficulties to differentiate. Radial nerve entrapment symptoms The symptoms of radial nerve entrapment are very similar to those of tennis elbow. 2Department of Diagnostic Radiology, School of Medicine, Keimyung University, Taegu, Korea. JRadial tunnel syndrome, also known as radial nerve entrapment, occurs when the radial nerve in the forearm gets compressed or pinched. ![]() The tunnel is expanded in those areas relieving pressure and ultimately pain.Journal of Korean Neurosurgical Society 1998 27(9): 1266-1270.īyung Kil Son, Jang Chul Lee, Chang Young Lee, Eun Ik Son, Dong Won Kim, Man Bin Yim, In Hong Kim, Sung Moon LeeġDepartment of Neurosurgery, School of Medicine, Keimyung University, Taegu, Korea. An incision is made at the outer aspect of the forearm near the elbow and the muscle tissues are manipulated so the surgeon can visualize any pressure points where the nerve is being pinched. The goal is to release any points of abnormal pressure as the radial nerve passes through the radial tunnel. ![]() When non-surgical methods fail to provide adequate relief or pain returns shortly after beginning activity, it may be time to consider surgical decompression. Your physician will also prescribe strengthening exercises for the forearm. It involves the posterior interosseus nerve however it can be differentiated from PIN syndrome based on the symptom profile. A special forearm brace can relieve symptoms and reduce stress on the affected area and palm up lifting is recommended. Radial tunnel syndrome is an uncommon and unique peripheral neuropathy. In more severe cases an injectable steroid may be used, however the effectiveness may diminish over time. Over the counter, anti-inflammatory drugs are taken to reduce the pain and irritation of the nerve. The first course of treatment consists in avoiding activities that have previously caused the symptoms to appear and thus to manage the pain. Generally, there are the non-surgical treatment options and surgical treatment options. In order to prevent radial tunnel syndrome symptoms, you should avoid activities that cause symptoms to appear and seek treatment at the first sign of symptoms. However it may require several months or even a year for full recovery. In more advanced cases, a decompression surgery may be used in which the radial tunnel is physically widened (released), allowing for more room for the nerve.Ī complete recovery can be expected within 8 months in most patients with proper treatment and rest from activities that cause symptoms. ![]() Certain muscles are strengthened by the use of weights or by surgery to prevent recurrence of symptoms. The use of elbow braces (cuff) is often recommended for preserving wrist movement while recovering from an attack. In more severe cases, a bulge may form over the tendons that are inflamed. Loss of grip strength in the hand and fingers caused by weakening muscles due to lack of use. Tenderness to touch on the outside of the elbow Symptoms of radial tunnel syndrome include : ![]()
