Does everyone have a Struthers ligament?
Prevalence. The ligament is not always present, and there is some debate as to its prevalence. Struthers originally estimated that it was present in 1% of humans.
How common is ligament of Struthers?
Its incidence was estimated by Struthers at 1%, but more recently has been estimated at 13.5%. Its clinical significance arises from the fact that the median nerve and brachial artery may pass through the “arch” formed by the process and ligament over the humeral body.
Where is the ligament of Struthers?
The Struthers’ ligament was described by anatomist John Struthers1 in 1854; it is a fibrous band that extends from a bone spur located on the anteromedial surface of the lower third of the humerus, known as the supracondylar process, and is inserted in the medial humeral epicondyle.
Which forearm nerve is the cause of humerus supracondylar process syndrome?
The median nerve and brachial artery pass under the ligament of Struthers and consequently can be compressed, causing supracondylar process syndrome.
How is ulnar nerve entrapment treated?
Ulnar Nerve Entrapment Treatment
- Occupational therapy to strengthen the ligaments and tendons in the hands and elbows.
- Drugs such as aspirin, ibuprofen and other nonprescription pain relievers to help reduce pain and inflammation.
- Splints to help immobilize the elbow.
What is Martin Gruber syndrome?
It is an anomalous pattern of innervation occurring between the median and ulnar nerves in the forearm. In a Martin-Gruber anastomosis, a crossover of axons from the anterior interosseous nerve (the exclusively motor branch of the median nerve) to the ulnar nerve in the forearm usually occurs.
What is bilateral median nerve compression caused by Struthers ligament?
Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve’s dermatomal area. The authors present the case of a 21-year-old woman with bilateral median nerve compression caused by Struthers’ ligament.
What is the ligament of Struthers syndrome?
The ligament of Struthers is thought to be a vestige of the tendon of the latissimo-condyloideus muscle, found in some climbing animals Supracondylar process syndrome: The median nerve is susceptible to entrapment at the distal humerus in the presence of a fibrosseous tunnel formed by the humerus and the ligament of Struthers.
Can the ligament affect the ulnar nerve?
The ligament may also affect the ulnar nerve after an anterior transposition surgery, which is a commonly performed to manage patients with a cubital tunnel syndrome, a form of ulnar nerve entrapment. It is unlikely that the ulnar nerves are affected in patients without transposition surgeries.
What are the symptoms of bilateral compression of the median nerve?
Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve’s dermatomal area. The authors present the case of a 21-year-old woman with … Struthers’ ligament syndrome is a rare cause of median nerve entrapment.
