The SP is also known as the supracondyloid process,
supratrochlear spur or the supraepitrochlear process.
It was given by using Ropivacaine 0.5 %.30 ml (max.) to block supraorbital,
supratrochlear, zygomaticotemporal, Auriculotemporal, greater & lesser occipital, greater auricular nerves for better analgesia & perioperative Haemodynamic stability.
It may vary in length from 2 to 20 mm." Buikstra and Ubelaker (1994:94) name this variation the
supratrochlear spur, defining it simply as a "process arising from medial supracondylar ridge 5-7 cm above the medial condyle of the humerus." Waldron (2009) clarifies that the tip of the supracondylar process may have, in life, been connected to the medial epicondyle by the ligament of Struthers, creating a tunnel for the brachial artery and the median nerve.
Common complications include pin site infections, pin loosening, pressure ulcers from under the vest, damage to the supraorbital and
supratrochlear nerves, and dysphagia.
The knee has three anterior fat pads; the infrapatellar fat pad, also known, as Hoffa's fat pad, the quadriceps (anterior suprapatellar) and the prefemoral (posterior suprapatellar or
supratrochlear) fat pads.
An example is the glabellar region, with the blood supply provided by small vessels branching from the
supratrochlear and supraorbital arteries with limited collateral circulation (8).
Small branches of the
supratrochlear and supraorbital arteries feed these areas, with little collateral circulation ("watershed area"; Figure 1).
b) Supraorbital and
Supratrochlear Nerve and Sphenopalatine Ganglion (SPG) Blocks
It has two terminal branches: the larger supraorbital and smaller
supratrochlear nerves.
Care must be taken not to violate the supraorbital nor
supratrochlear pedicles during this dissection.
The scalp derives its blood supply mainly from the four superficial branches of the external carotid artery, the superficial temporal, angular, occipital, and posterior auricular arteries, and the supraorbital and
supratrochlear branches of the internal carotid.
