However, unfortunately, the excision margins adjacent to the scalenus
medius muscle were positive.
Observation Sex Total Female Male Cx rib only 48 (40%) 6 (32%) 54 (39%) Cx rib and fibrous band 37 (31%) 9 (47%) 46 (33%) Cx rib and hypertrophied 7 (6%) 1 (5%) 8 (6%) scalenus
Structures in this region commonly assessed by clinicians include the cervical lymph nodes, external jugular vein, brachial plexus, SCM and scalenus
The lateral surface of the ganglion was covered with the medial scalenus
muscle as in left side.
A moderate decrease in right lateral flexion and right rotation associated with muscular spasms (bilaterally) at the cervical paraspinal and scalenus
muscles was present.
It blends with the parietal pleura and is reinforced by the scalenus
The subclavian vein lies anteriorly, separated from the artery by anterior scalenus
as it inserts into the first rib at the tubercle of Lisfranc.
Surgical treatment for symptoms produced by cervical ribs and the scalenus
Other causes of brachial plexus neuropathies include compression and pinching of the nerves due to anatomical variations and clinical complications caused by clavicle fracture, thoracic outlet syndrome, scalenus
syndrome, pectoralis minor syndrome, and presence of a cervical rib (Ghefter et al, 2012).
It passes between longus colli and scalenus
anterior muscle, behind the common carotid artery and the vertebral vein through the foramina in the transverse processes of all of the cervical vertebrae except the seventh, curves medially behind the lateral mass of the atlas and enters the cranium via the foramen magnum.
The key points in both the approaches are (1) complete resection of bony, cartilaginous, and fibrous parts of (2) complete resection of the scalenus
anterior muscle at the scalene tubercle on the first rib and (3) arterial exploration and reconstruction.
