Hence, the aim of this study was to give detailed anatomical information about the pronator teres muscle innervation.
thous have an anatomical disposition similar to the domestic dog, but inter and intraspecific variations can be observed due to the formation of accessory muscles such as the accessory belly of the ulnar head of the flexor carpi ulnaris muscle; the vestigial presence of the anconeus epitrochlearis muscle; and the independent innervation of the musculocutaneous nerve to pronator teres muscle.
While passing toward the interosseous membrane, the common interosseous artery was separated from the median and anterior interosseous nerves by the ulnar head of the pronator teres muscle (Figure 2).
Variations of the pronator teres muscle: predispositional role to median nerve entrapment.
A course of fascial stripping techniques was initiated, including: cross friction massage, instrument assisted fascial stripping to the medial epicondyle area and over the belly of the pronator teres muscle using gua sha tools, ischemic compression of the trigger point found in the pronator teres, active assisted compressions to the trigger point noted in the pronator teres, and general mobilizations of the carpals, specifically the scaphoid as this carpal was noted to be restricted on motion palpation.
Along its course, part of this nerve enters the axilla of the shoulder, runs immediately adjacent to the biceps, and descends within the hollow of the elbow under the pronator teres muscle and the bicipital aponeurosis.
