Infrequently, the long thoracic nerve does not pass through scalenus medius and the nerve trunk is formed over the first rib. |
|
No patients had anatomic abnormalities of the thoracic inlet, such as a hypertrophied scalenus anticus tendon or an obstructing tumor. |
|
If the scalenus pulls the ribcage, it affects the QL as well, thus affecting pelvic posture. |
|
The QL pulls from one end of the rib cage and the scalenus from the other end. |
|
Occasionally, all the cardinal signs and symptoms of a scalenus anticus syndrome may confuse the clinical picture. |
