Ulnar nerve entrapment is the compression or pressure of the ulnar nerve in the elbow region. The ulnar nerve is a nerve that passes through the elbow and gives movement and sensation to the hands and fingers. Ulnar nerve compression occurs as a result of compression of the tissues in the area where the nerve passes. The ulnar nerve is a nerve that arises as part of the brachial plexus and carries movement and sensation from the elbow to the hands and fingers.
Here are some basic information about the anatomy of the ulnar nerve:
Ulnar nerve, It arises from the C8 and T1 spinal nerve roots of the brachial plexus. After these nerve roots exit the spinal cord, they unite in the brachial plexus and form the ulnar nerve. The ulnar nerve, which reaches the elbow by passing through the axillary region of the brachial plexus, passes through a structure known as the cubital tunnel in the elbow region. This tunnel passes under a protrusion on the inside of the elbow bone called the medial epicondyle. Passing through the carpal tunnel at the wrist, it branches into the middle finger, ring finger, and little finger of the hand. The branches of the ulnar nerve provide movement and sensation to the muscles in the wrist and hand. At the same time, these branches control the joints and muscles of the fingers.
The ulnar nerve is surrounded by skin, muscle and connective tissue in the elbow and hand regions. If the nerve is subjected to compression or pressure, deterioration of nerve function and related symptoms may occur. The anatomical structure and path of the ulnar nerve are important for providing movement and sensation to the hand and fingers. However, in some cases, functional problems may occur due to nerve compression or pressure.
Causes of ulnar nerve compression may be: compression of the median nerve. However, in some cases, the ulnar nerve may also be affected and compressed.
Cubital tunnel syndrome: The cubital tunnel is a narrow channel in the elbow region where the ulnar nerve passes. The narrowing of this canal can cause compression of the nerve. Cubital tunnel syndrome may develop when the elbow is bent or exerted on the elbow for a long time.
Trauma or injury: Elbow b Blows, fractures, or other injuries to the ulnar nerve can lead to compression of the ulnar nerve. Anatomical structural disorders: Congenital or acquired anatomical disorders can narrow and compress the area where the nerve normally passes.
Ulnar nerve entrapment is usually seen in the following people: Those who work in jobs that require repetitive elbow movements for a long time. Those who are involved in sports that put weight on the elbow or compress the elbow. Those with a history of wrist or elbow injury. Those with certain systemic conditions such as diabetes, rheumatoid arthritis, or thyroid disease. Conservative treatment methods such as activity modification, use of elbow splints, physical therapy and wrist-elbow exercises can be tried. Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) or injections of corticosteroids can help reduce pain and inflammation. Surgical intervention: In cases where there is no response to conservative treatments or when symptoms become severe, surgical intervention may be required to correct structures compressing the ulnar nerve. The treatment option is determined by the severity of the symptoms, the lifestyle of the patient, and the underlying causes
