What is "Scalenus Anticus syndrome" ?
- gangadharan nairLv 71 decade agoFavourite answer
Symptoms due to compression of the brachial plexus and subclavian artery by the scalenus anticus muscle. Please also see Thorasic outlet compression syndromes.
Thoracic outlet compression syndromes are a group of poorly defined disorders characterized by pain and paresthesias (an abnormal or perverted sensation due to disorder of the sensory nervous system) in the hand, neck, shoulder, or arms. They appear to involve compression of the lower trunk of the brachial plexus (and perhaps the subclavian vessels) as it traverses the thoracic outlet below the scalene muscles and over the 1st rib before entering the axilla, but this involvement is unclear. Diagnostic techniques have not been established. Treatment includes physical therapy, analgesics, and, in severe cases, surgery.Source(s): http://en.wikipedia.org/wiki/Thoracic_outlet_syndr... http://www.nlm.nih.gov/medlineplus/ency/article/00... http://www.merck.com/mmpe/sec16/ch223/ch223l.html#... http://www.google.co.in/search?q=Scalenus+Anticus+...

Another condition that can tie in with the rib subluxations is Scalenus Anticus Syndrome. Being a bit rusty on your Latin, you may ask, "What is that?" It is best described by first looking at the anatomy of the neck. Note the three scalene muscles that go from the side of the top cervical vertebrae down to the first two ribs. Their function is to flex the head and neck and to assist in breathing.
The scalene muscles are used and overused daily during many movements. An example is that any pulling done by the arm from front to back, such as a supermarket checker might do, could cause the muscles to overwork, get larger (hypertrophy) and cause some compression on the nerves going to the hand.
Another common situation is that when you are anxious, you will tend to breathe from your upper chest, instead of using your abdomen and diaphragm. You will probably lean your head forward in an abnormal posture. You may also hunch your shoulders up, looking like a turtle. This all leads to chronic tension in the scalene muscles. The muscles will develop "trigger points" that, when pressed, may give a painful "doorbell sign" down the neck and arm. The trigger points may also refer pain into the chest, shoulder, back and sides of the arms, and even to the medial or inside edge of the shoulder blade. It may be so bad that the anterior and middle scalene muscles clamp down on the subclavian artery and brachial plexus, restricting nerve impulses and blood flow to the arm and hand. In plain language, your hands may develop numbness, tingling, pain, and coldness. You may be incorrectly diagnosed as having carpal tunnel syndrome.
so someone u know is suffering from this get this diagnosed properly.....
A combination of myofascial release and chiropractic adjustment of the neck works quite effectively to relieve the tension in tissues, reduce the abnormal motion of the neck, and, hence, reduce the problems due to pressure on the nerves and blood vessels. Your doctor may use a "spray and stretch" technique, developed by Janet Travell, MD, which uses a cold spray on the neck to temporarily numb the tissues while they are stretched beyond their normal pain tolerance. It is not as unpleasant as it sounds -- it is quick and almost painless.
But for the treatment to be effective long-term, you must also address the poor posture and tendency to hold anxiety and tension in the neck. As I have pointed out in prior articles, there are a number of simple things you can do each day to help yourself:
Be aware of your posture.
Adjust your computer workstation.
Take stretch breaks every half hour. Here are two neck stretches.
Learn to relax and breathe deeply from the abdomen and diaphragm.
And, of course, stand tall when dancing - your coach can help.

Thoracic outlet syndrome (TOS) consists of a group of distinct disorders that affect the nerves in the brachial plexus (nerves that pass into the arms from the neck) and various nerves and blood vessels between the base of the neck and axilla (armpit). For the most part, these disorders are produced by positional compression of the subclavian artery and vein, the vertebral artery, and the nerve cords of the brachial plexus. The disorders are complex, somewhat confusing, and poorly defined, each with various signs and symptoms not only arising from the upper extremity but also from the chest, neck and head. The chest pain can mimick anginal pain.
An alternate taxonomy of TOS is used in ICD-9-CM and other sources:
Scalenus anticus syndrome (compression on brachial plexus and/or subclavian artery caused by muscle growth) - diagnosed by using Adson's sign with patient's head turned outward
Cervical rib syndrome (compression on brachial plexus and/or subclavian artery caused by bone growth) - diagnosed by using Adson's sign with patient's head turned inward
Costoclavicular syndrome (narrowing between the clavicle and the first rib) -- diagnosed with costoclavicular maneuver.
