I have seen this practised in one very remarkable case by Mr. Syme, in which the glenoid cavity and neck of the scapula were extensively diseased, while the head of the bone was quite sound.
The glenoid must then be carefully examined, and any diseased bone removed by the cutting pliers.
When the glenoid is also diseased, mere gouging or scraping the cartilaginous surface will not suffice, but the neck must be thoroughly exposed, so that the whole cup of the glenoid may be removed by powerful forceps.
The condyles of the humerus articulate with the glenoid cavities of the radius and a portion of the ulna.
Because of the large humeral head articulating as it does with a glenoid cavity, scapulohumeral luxations are very rare in the horse.
The scapulohumeral joint is an enarthrodial (ball and socket) joint wherein the ball or humeral articulating head greatly exceeds in size the socket or glenoid cavity of the scapula.
Defn: Situated behind the glenoid fossa of the temporal bone.
In a few cases the condyle has been driven through the floor of the glenoid cavity, causing fracture of the base of the skull.
In sub-coracoid dislocation the head of the humerus may be indented by coming in contact with the anterior edge of the glenoid cavity (F.
A partial fracture carrying away the lower part of the glenoid cavity simulates a sub-glenoid dislocation.
The line of fracture runs through the scapular notch, downwards and laterally to the lower margin of the glenoid, so that the glenoid and the coracoid process are separated from the rest of the bone.
The simplest of these is the sub-glenoid variety, in which the head rests on the long tendon of the triceps, where it arises from the axillary border of the scapula just below the glenoid cavity.
Sometimes the condyle of the lower jaw is driven through the base of the skull by a blow or fall on the chin, and fissures radiate into the base from the glenoid cavity.
The spine of the scapula becomes more and more prominent towards its inferior extremity, where it ends in a twisted and inflexed portion, which represents the acromion process; this process terminates at the level of the glenoid cavity.
The scapula is markedly narrowed in the region above the glenoid cavity.
Furthermore, a bone named the coracoid joins the scapula to the sternum; this bone, often fused with the scapula, where it contributes to the formation of the glenoid cavity, represents in birds the coracoid process of the human scapula.
In the ox, in which the acromion process, which is very rudimentary, does not attain the level of the glenoid cavity, the acromion portion is but slightly marked off from that which takes its origin from the spine of the scapula.
Behind the glenoid cavity is found the external auditory canal, and, further back still, the mastoid process.
Above and in front of the glenoid cavity is found a strong process consisting of a rugous base, and a summit which is directed inwards.
This difference of direction is correlated with the position of the scapula, the glenoid cavity of which, as we have already seen, is in man turned outwards, whereas in quadrupeds it looks downwards.
The anterior border (cervical) is strongly convex in the part next the glenoid cavity.
It arises above from a tubercle at the base of the coracoid process, which surmounts the glenoidcavity of the scapula.
The region occupied by the glenoid cavity is separated from the body of the bone by a constriction--the neck of the scapula.
The condyle of the lower jaw is so broad, and fits so accurately into its socket, the glenoid cavity, that there can be no departure from the up and down scissor-like action.
The malar always extends back to form part of the glenoid cavity.
The glenoid foramen is large; the condyloid foramen is conspicuous, and the carotid canal is deep within the foramen lacerum posterius.
As in many Marsupials, the jugal bone sometimes extends backwards to the glenoid cavity, where the lower jaw articulates.
Skull elongated and depressed; face long, narrow and concave above; bony palate extending as far backwards as the level of the glenoid fossa; and palatal bones dilated.
The postglenoid process of the skull so strongly developed, and the glenoid fossa so deep, that the condyle of the lower jaw is firmly held in place after the soft parts are removed.
Suborbital foramen small, and the palate, as in all the succeeding genera of this group, produced backwards about midway between the last molar and the glenoid fossa.
The condyle of the lower jaw is a transversely placed half-cylinder working in a deep glenoid fossa of corresponding form.
When the mouth is opened wide, the condyle advances out of the glenoid cavity, and returns to its socket when the mouth is shut.
At its outer angle it has a shallow cup known as the glenoid cavity.
The raised portion immediately dorsal to the glenoid fossa exhibits an unfinished surface, suggesting the presence of either cartilage or a ligament.
On the medial surface of the mandible, the prearticular and articular bones meet in a ridge that ventrally rims the glenoid cavity (Fig.
A small hollow above the ridge, anterior to the glenoid cavity, faces the medial plane of the skull and is bordered by the articular bone behind and above, and by the Meckelian fossa in front.
The HIP JOINT, like the shoulder, is a ball and socket, but does not allow such free movement; this is due to the fact that the socket or acetabulum is deeper than the glenoid cavity and that the capsule is not so lax.
In the four inner fingers theseglenoid ligaments, as they are called, are joined together by the transverse metacarpal ligament.
The scapula of Notoryctes has a very high overhanging spine, and there is a second strong ridge running along the proximal part of the glenoid border.
It is characteristic of the skull in Carnivora that the glenoidfossa is deep, and the postglenoid process (fig.
It is attached by muscle to the vertebral column, and is divided on either side into dorsal and ventral portions by a cavity, the =glenoid cavity=, at the point where the anterior limb articulates.
The jugal forms part of theglenoid cavity for articulation with the mandible, and also extends forwards so as to meet the lachrymal.
The jugal always extends back to form part of the glenoid fossa.
Around the glenoid cavity is an area which is mainly ossified and is continuous with the scapula.
The zygomatic arch is always complete, and in many cases the jugal extends back to form part at least of the glenoid surface for articulation with the mandible.
The scapula forms about half the =glenoid cavity= (fig.
The coracoid is a short bone attached above to the scapula and below to the presternum; it forms a large part of the glenoid cavity.
The dorsal end is continuous with an area of unossified cartilage which separates the coracoid and scapula and forms part of the glenoid cavity.
It takes no part in the formation of the glenoid cavity.
Between it and the glenoidsurface of the squamosal is the =postglenoid= foramen (fig.
The scapula in the Proboscidea has a large rounded suprascapular border and a narrow, slightly concave glenoid border.
The clavicle, coracoid, and scapula on each side form a bony articulation at the glenoid fossa.
A bifurcation of the ventral end of the scapula results in a large glenoid foramen.
The scapula in the Urodele and other Batrachians is entirely or almost wholly excluded from the glenoid foramen, and above the coracoid.
At the boundary between the scapula and the coracoid, on the hinder border of the plate, is placed the glenoid articular cavity to carry the head of the humerus.
This process, known as the coracoid process, is held by Sabatier to be the praecoracoid; while this author also holds that the upper third of the glenoid cavity, which ossifies by a special nucleus, is the true coracoid.
It was then found necessary to saw off the ragged and spongy part of the scapula, leaving only about a fourth part of that bone, containing the glenoid cavity, processes, and half of its spine.
Fractures of the glenoid cavity, of the neck of the scapula, and of the neck of the humerus, are all treated by the same simple, though effectual, apparatus as employed for injuries of the clavicle.
The glenoid cavity may, in consequence of being seriously involved in disease, also require removal; this is best accomplished by large cross-cutting pliers.
This is limited in front by the tendon of the extensor pedis, on each side by the lateral ligaments of the joint, and behind by the glenoid fibro-cartilage.
Instead of the glistening and clear appearance it ordinarily presents, its glenoid cartilage is found to be showing hæmorrhagic or even purulent spots of necrosis.
The skull has been cut vertically in two at the plane of the glenoid fossae.
In addition to the part of the cranium anterior to the glenoid fossae, the lower jaws are preserved complete.
The rostrum, left zygomatic arch, palate, left pterygoid, left glenoid fossa and right postorbital process are intact.
No case of fracture of the glenoid cavity happened to come under my notice.
The latter fragment had become somewhat displaced downwards, and had united in such a manner that the head rested on the lower part of the glenoid cavity.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "glenoid" in a variety of sentences. We hope that you will now be able to make sentences using this word.
