scapula

the flat triangular bone in the back of the shoulder. See anatomic Table of Bones in the Appendices.
winged scapula one having a prominent vertebral border usually owing to weakness of one of the muscles holding the scapula in place.

scap·u·la

, gen. and pl.

scap·u·lae

(skap'yū-lă, -lē), [TA]
A large triangular flattened bone lying over the ribs, posteriorly on either side, articulating laterally with the clavicle at the acromioclavicular joint and the humerus at the glenohumeral joint. It forms a functional articulation with the chest wall, the scapulothoracic articulation.
[L. scapulae, the shoulder blades]

scapula

(skăp′yə-lə)
n. pl. scapu·las or scapu·lae (-lē′)
Either of two large, flat, triangular bones forming the back part of the shoulder. Also called shoulder blade.

scap·u·la

, pl. scapulae (skap'yū-lă, -lē) [TA]
A large, triangular, flattened bone lying over the ribs, posteriorly on either side, articulating laterally with the clavicle at the acromioclavicular joint and the humerus at the glenohumeral joint. It forms a functional joint with the chest wall, the scapulothoracic joint.
Synonym(s): shoulder blade.

SCAPULA
The large, flat, triangular bone that forms the posterior part of the shoulder. It articulates with the clavicle and the humerus. Synonym: shoulder blade See: illustration; triceps

plane of scapula

The angle of the scapula in its resting position, normally 30° to 45° forward from the frontal plane toward the sagittal plane. Movement of the humerus in this plane is less restricted than in the frontal or sagittal planes because the capsule is not twisted.
See: Scapula Instability

tipped scapula

A condition in which the inferior angle of the scapula is prominent, usually the result of faulty posture and a tight pectoralis minor muscle. Tipping is a normal motion when a person reaches with the hand behind the back.

winged scapula

Condition in which the medial border of the scapula is prominent, usually the result of paralysis of the serratus anterior or trapezius muscles. Synonym: angel's wing

scapula

The shoulder blade. A flat, triangular bone with a prominent, near-horizontal raised spine, lying over the upper ribs of the back. At its upper and outer angle the scapula bears a shallow hollow with which the rounded head of the upper arm bone (the humerus) articulates. The spine ends in a bony process, the coracoid process, the end of which connects with the outer end of the collar bone (clavicle).

In the present study, the number (%) of notch types of glenoid cavity of 63 scapulae, in descending order, were as follows: type 1a (notch in shallow concave form) 24 (38.10%), type 2a (prominent angular notch) 17 (26.98%), type 0 (notch is absent) 13 (20.63%), type 2b (prominent angular notch with prominent protuberance margin) 6 (9.53%), type 1b (notch in shallow concave form with prominent protuberance margin) 3 (4.76%) (Figure 2), (Table 1).
In the present study, the mean length of the acromion process was observed to be 4.22 cm and 4.24 cm on the right and left scapulae which did not show much variation with other studies.
For example, a patient may have a seemingly normal scapular resting height, but still have a tendency of pulling their scapulae back and down during exercise, or have scapular dyskinesis, which may lead to intermittent compression of the neurovascular bundle.
The DSN then runs inferiorly and slightly laterally between the superior fibres of the upper trapezius medially and the levator scapulae laterally.
Analyses of body posture parameters related to asymmetries in trunk inclination, position of the shoulders, position of the scapulae and their distance from the spine, position of the pelvis, and shape of the spine in the coronal plane have shown no significant differences between the group of preterm children and the group of full-term children, regardless of the assumed posture (Table 2).
Keeping elbows straight, press your hands into the floor to separate the scapulae. Release and allow the scapulae to return to starting position.
The humeral liner and scapulae with rTSA baseplate and glenosphere were positioned in the biaxial testing apparatus and aligned along the SI axis of the glenoid baseplate (Fig.
Although pain is not necessarily a part of this condition, when this condition has existed for a long time, the client does often experience upper back and neck pain, both due to the tightness of the upper trapezius and levator scapulae, and due to the accompanying imbalanced posture of the head that places increased stress on all the posterior extensor musculature of the cervicothoracic region.
Because of its numerous origins, the trapezius is able to move the scapulae in several different ways: the upper fibers raise and assist with upward rotation of the scapulae, the middle fibers (along with the rhomboid muscles) pull the scapulae together, and the lower fibers lower and also assist with upward rotation of the scapulae.
Results: It was found that complete ossification of superior transverse scapular ligament was found in 4 out of 204 scapulae. The incidence was 1.96% in Pakistani population.
Procedures--Following a 7-day period of consistent egg laying, quail were anesthetized and received a 4.7-mg deslorelin implant (treatment group; n = 10) or identical placebo implant (control group; 10) SC between the scapulae. Egg production was monitored daily.
