Cervical rib syndrome
From WikiCNS
- Rare entity associated with upper extremity weakness (atrophy of the thenar eminence), arm pain (medial forearm), and cervical ribs
- Occurs typically in young and middle aged females
- Symptoms due to compressive fibrous band, continuous with the medial edge of the scalenus medius (middle scalene muscle); band extends from the rib or elongated transverse process of C7 to the first rib and compresses the lower portion of the brachial plexus
- Treatment: surgery through supraclavicular incision with dissection down to the plexus and retraction on the omohyoid; subclavian artery is elevated and compressive band is cut
