Brachial plexus injury of getting BPI. The site and type of brachial plexus injury determine the prognosis. Avulsion and rupture injuries require timely surgical intervention for any chance of recovery. For milder injuries involving buildup of scar tissue and for neurapraxia, the potential for improvement varies, but there is a fair prognosis for spontaneous recovery, with a 90–100% return of function. Brachial plexus injury A brachial plexus injury (BPI), also known as brachial plexus lesion, is an injury to the brachial plexus, the network of nerves that conducts signals from the spinal cord to the shoulder, arm and hand. These nerves originate in
Transverse cervical artery anastomoses with the deep and dorsal scapular artery which in turn links to the subscapular artery. This anastomosis is a ring circulation around the scapula where it continues to the suprascapular artery via the circumflex scapular artery. The dorsal scapular artery (or descending scapular artery) is a blood vessel which supplies the levator scapulae, rhomboids, and trapezius. It most frequently arises from the subclavian artery (the second or third part), but a quarter of the time it arises from the transverse cervical artery. In that case, the artery is also known as the deep branch of the transverse cervical artery,
