What's the difference between glenoid and postglenoid?
Glenoid
Definition:
(a.) Having the form of a smooth and shallow depression; socketlike; -- applied to several articular surfaces of bone; as, the glenoid cavity, or fossa, of the scapula, in which the head of the humerus articulates.
Example Sentences:
(1) (b) abnormal morphologic of the glenoid fossa, mandibulars condyle and the neck of mandibula were seen.
(2) This fracture was isolated in one case, being in the other six cases combined with injuries, either to acromioclavicular dislocation or to fracture of the superior glenoid cavity disorder.
(3) Five shoulders had a posterior opening-wedge osteotomy of the scapular neck to correct the excessive retroversion of the glenoid cavity.
(4) A comparative cephalometric and tomographic study prior to the treatment and after completion of the treatment revealed the following results: an improvement in the occlusal relationships due to both skeletal (an anterior mandibular displacement and an increase in the mandibular length) and dentoalveolar changes; it was possible to produce a growth stimulation of the mandibular condyle associated with a translation of the glenoid fossa by using an elastic activator; there was a direct correlation between the effects of the treatment and the age period of the patients (mixed dentition).
(5) However, separation of the capsule from the bony glenoid can be detected if a joint effusion is present to adequately distend the joint.
(6) Damage to the anterior glenoidal labrum was seen in all the younger patients and in 75% of the older ones.
(7) The capsule is reattached to the boney rim of the anterioinferior glenoid deep to and lateral to the torn cartilagenous labrum, thus excluding the labrum from the joint anteriorly.
(8) One hundred and seventeen shoulders in 113 patients were treated surgically for recurrent anterior dislocation of the shoulder by the Latarjet procedure - transplantation of the coracoid process to the anterior border of the glenoid fossa.
(9) A three-dimensional configuration of the temporomandibular joint was constructed by 108 triangles for the condyle and 180 triangles for the glenoid fossa.
(10) Conservative surgical treatment without excision of the synovial membrane or meniscus but including arthroplasty of both the eminence and the lateral side of the glenoid fossa was successful.
(11) The computerized tomographic scans showed uneven wear of the glenoid surface, osteophytes, large cysts, and posterior displacement of the humeral head.
(12) The eleven fractures of the acromiom, glenoid, or coracoid process resulted in loss of motion in ten of the eleven shoulders.
(13) Arthroscopic operative procedures include the inspection of a torn glenoid labrum and certain lesions of the biceps tendon, viewing a torn rotator cuff, locating loose bodies in the shoulder, surgery for recurrent dislocations, and division of the coracoacromial ligament.
(14) Air is sometimes present in the glenoid fossa of the temporomandibular joint (TMJ) at computed tomography (CT) of acute basilar skull fractures.
(15) The zygomatic process of the temporal bone forming the articulating surface of the glenoid fossa was resected in 25 young New Zealand rabbits in order to investigate the effect of function on the growth of the condylar cartilage.
(16) Bony defects of the humeral head (Hill-Sachs lesion) or the glenoid rim are revealed by computed tomography (CT).
(17) That type in which the fracture is localized in the glenoid cavity is the most injurious one as it is accompanied by haemorrhage and therefore will result in loss of meat.
(18) The condylar stump was used in combination with a glenoid fossa implant by performing a unilateral osteotomy 6 months after the tumor was excised.
(19) No correlations were found between any of the radiographic findings (the presence of radiolucent lines about the glenoid or humeral components, humeral subsidence, or ectopic ossification) and any of the clinical findings (pain relief, range of motion, motor power, or functional improvement).
(20) Although Tuttle and Basmajian suggest that the cranial orientation of the glenoid fossa in apes has reduced the demand for scapular rotation during arm-raising, subsequent EMG studies on other primate species suggest that these muscles do play a significant role in arm motion during active locomotion.
Postglenoid
Definition:
(a.) Situated behind the glenoid fossa of the temporal bone.
Example Sentences:
(1) It commences at the postglenoid vein and connects the distal end of the petrosquamous sinus to the pterygoid venous plexus.
(2) Also emptying into the postglenoid vein is the petrosquamous sinus.
(3) Characteristic expression of the defects included 1) temporo-zygomatic hyperplasia involving the articular tubercle and postglenoid process and 2) mandibular hypoplasia, primarily of the condyles and the angular and coronoid processes.
(4) It is hypothesized that a high percentage of balancing-side muscle activity in ferrets can be recruited during carnassial biting because the postglenoid process prevents ventral displacement of the working-side mandibular condyle.
(5) Animals who had posterior displacement of the condyles showed evidence of resorption of the posterior surface of the condyle and anterior surface of the postglenoid spine.
(6) The orbit is drained by a wide cranio-orbital sinus which empties into the postglenoid emissary vein.
(7) It was found that Cebus have a venous arrangement fundamentally the same as in man, differing only in that: 1. the monkey has no inferior sagittal sinus, spenoparietal sinus, and emissary parietal and condylar veins; 2. the occipital sinus is not in connection with other sinuses; 3. there are a spenopetrosal sinus, a petrosquamous sinus, and an unpaired inferior cerebellar vein; 4. besides the internal jugular vein, there is additional intracranial drainage through the petrosquamous sinus and the postglenoid vein; 5. the superficial middle cerebral vein opens into the petrosquamous sinus; 6. the lingual and facial veins are not tributaries of the internal jugular vein; 7. there is a bilateral uniform division of the superior sagittal sinus at the confluence of the sinuses to drain equally into both transverse sinuses; 8. the vascular pattern appears to be quite stable; anatomical variations appear to be few and unimportant.
