Percentage of times that the dominant upper trapezius, lower trapezius, infraspinatus and serratus anterior muscles
fired in a specific order during abduction in the scapular plane.
Our case describes a muscle that is inserted anteriorly, as the cases described by the aforementioned authors, on the first costal cartilage, but we found a difference concerning the posterior insertion, since it does not present any bone insertion, and, on the contrary, it ends on the serratus anterior muscle
's fascia, close to the superior margin of the scapula.
Many authors described that the scapular OC with a large bursa penetrated the subscapularis and serratus anterior muscles
and that the bursae were formed along the chest wall; although Chiarelli et al.
A vertical skin incision is made parallel to the anterior border of the latissimus dorsi muscle, and the serratus anterior muscle
is identified (figure 2, B).
The serratus anterior muscle
, which had been conserved during the previous surgery, was also detached to enable the inferior angle of the scapula to be raised sufficiently, after which the inferior angle of the scapula was locked inside the thorax and marked with an electric scalpel.
In contrast, the serratus anterior muscle
on the most lateral implant pocket's baseline part (red line in "c" of [Figure 5]) could be elevated.
SUMMARY: While dissecting the body of a 59 years old male cadaver we observed "abnormal" branching pattern of the axillary artery and unusual vascular pedicles of the serratus anterior muscle
. The serratus anterior branch originated directly first part of the axillary artery as the first branch.
(1994) Anomalous blood supply to the serratus anterior muscle
Distally, the muscle inserted in various points of the scapulae, as well as the fasciae of the serratus anterior muscle
. Just before its insertion, we also observed the splitting of the muscle into 2 flaps.
Trapezius weakness is evidenced by lateral winging, which is differentiated from the medial winging seen in weakness of the serratus anterior muscle
Muscles measured included the upper and lower trapezius; anterior, middle and posterior deltoids; supraspinatus; infraspinatus; and serratus anterior muscles
. Each participant performed 10 repetitions of shoulder abduction with their dominant arm.
However, insertion sites may vary and include the medial clavicle as well as the sternocleidomastoid and serratus anterior muscles
. (5,6) The exact insertion site may be difficult or impossible to adequately determine.
