2] Most of these ossification centers
mutually fuse, but approximately 2% of them remain dissociated.
Thus, in the present study, two different piglet age groups were designed to explore the effects on the trial methods of different ratios of ossification center
and epiphyseal cartilage.
During this phase, there are two ossification centers
in the posteroinferior part of the nasal septum; they are located between the nasal septal cartilage medially and the nasopalatine nerves laterally.
The nucleus takes on an appearance with a multiple granular pattern, with an ossification center
made up of multiple independent nuclei that grow and finally coalesce to form only one (9); on average, around 5 years of age (5).
The vomer is the last to present an ossification center
Ossification of membranous bones progresses along radially trabecular deposition from the ossification center
(Ohtsuki 1977), as seen in Figure 5a, and is followed by deposition of secondary trabeculae that progressivelly close the spaces, as in Figure 5b.
This condition was described as early as 1863, when Gruber noted the presence of an os acromiale with fibrocartilaginous union of the anterior acromial ossification centers
in three out of 100 cadaveric specimens (in a review by Kurtz and colleagues (2)).
Ultrasound evaluation of the distal femoral ephiphyseal ossification center
as a screening test for intrauterine growth retardation.
The vertebral ring apophysis appears as a secondary ossification center
at approximately 10 years of age.
The anterior ossification center
is termed the pre-acromion, the middle is the meso-acromion, and the posterior is the meta-acromion.
Calcaneal apophysitis a quantitative radiographic evaluation of the secondary ossification center
Several anatomical variations in the developing elbow can be mistaken for fractures but are actually normal: apparent angulation of the radial neck, a wedge-shaped radial head, late-ossifying medial epicondyle physis, capitellar physis that's wider at the back end, and a widely separated ossification center
at the olecranon.
The axillary lateral view provides a perpendicular view of the shoulder joint, permitting visualization of an unsuspected posterior dislocation, fracture or an abnormal acromial ossification center
A shell-like ossification center
over the tip of the CP is present until epiphyseal fusion at 18-25 years of age .
The entire capitellar ossification center
is fragmented with sclerosis and alternating rarefaction.
