A Case Report on Unilateral Accessory Humeral Head of Pronator Teres

Abstract

An accessory muscle was observed in left upper limb of a 50-yearold male cadaver during routine undergraduate dissection class. This muscle was seen in arm, proximal to the humeral head of pronator teres and eventually fusing with it distally. It was subsequently identified as the accessory humeral head of pronator teres.

Dextrose hydrodissection with ultrasound-guided as optional therapy in pronator teres syndrome: A case report

“…Pronator teres syndrome (PTS) or pronator syndrome is a syndrome of irritation of the proximal median nerve that occurs due to compression of the pronator teres muscle or the surrounding anatomical structures. [1][2][3] [4] Pronator syndrome is included in a variety of cases of peripheral neuropathy of the median nerve that rarely occurs compared to the others, such as carpal tunnel syndrome (CTS) and anterior interosseous nerve syndrome (AINS). [2] In one study, the prevalence of pronator teres syndrome was mentioned in only 5% of all cases of median nerve neuropathy.…”

“…With ultrasound guidance, this technique is considered safe and effective, especially in cases of nerve clamping, including PTS. [4][6] [7] Several choices of fluids used in the hydrodissection technique include NS (Normal Saline), corticosteroids, 5% dextrose (D5W), and PRP (Platelet-rich Plasma). [4][8] 5% dextrose is very commonly used in clinical practice as there has not been found any significant side effects compared to other options.…”

[9] However, until now the exact effectiveness of these medical properties has not been widely proven by various studies.…”
