The tuberculous process, as a rule, begins in the epiphysis in the long bones, and may affect any of the bones.
These tumors may arise from the marrow, but generally in the epiphysis of the bone and extend to the shaft only at a later stage of their development.
The process nearly always begins in the diaphysis, but then may extend into the epiphysis and produce suppuration of the joint.
The union of the epiphysis to the diaphysis commences during puberty, hence these fractures are less common in childhood than after the ages of eleven or twelve.
The epiphysis of the olecranon being so distinct and showing no fusion, indicates the youth of this soldier, whose age could not have been more than 16 years.
The bullet under these ballistic conditions of high velocity and not distant range might have bored its way through the cancellous tissue of the epiphysis of the same bone without any fractures.
Dean concludes that "the pineal structures of the true fishes do not tend to confirm the theory that the epiphysis of the ancestral vertebrates was connected with a median unpaired eye.
It would appear, on the other hand, that both in their recent and fossil forms the epiphysis was connected in its median opening with the innervation of the sensory canals of the head.
In some of the lizards this epiphysis is largely developed, bearing at its tip a rudimentary eye.
In none of the fishes is the epiphysis more than a nervous enlargement, and neither in fishes nor in amphibia is there the slightest suggestion of its connection with vision.
In the acute arthritis of infants, the epiphysis concerned may be separated and displaced.
Separation of an epiphysis nearly always results in infection and destruction of the adjacent joint.
When there is marked rarefaction of the bone at the ossifying junction, the epiphysis is liable to be separated--epiphysiolysis.
The first of these terms is misleading, because the lesion involves the ossifying junction and the shaft of the bone, and the epiphysis only indirectly.
The articular aspect of the epiphysis is invested with a thick layer of hyaline cartilage, known as the articular cartilage, which would appear to be mainly nourished from the synovia.
Femur and Tibia showing results of Acute Osteomyelitis affecting Trigone of Femur; sequestrum partly surrounded by new case; backward displacement of lower epiphysis and implication of knee-joint.
The separation usually takes place through the young bone of the ossifying junction, and the surfaces of the diaphysis and epiphysis are opposed to each other by irregular eroded surfaces bathed in pus.
The infection may spread to the adjacent joint, either directly through the epiphysis and articular cartilage, or along the deep layer of the periosteum and its continuation--the capsular ligament.
When the epiphysis is intra-articular, as, for example, in the head of the femur, the pus when it reaches the surface of the bone necessarily erupts directly into the joint.
The skiagram may also show separation and displacement of the adjacent epiphysis and destruction of the articular surfaces or dislocation of the joint.
Sometimes the separated and displaced epiphysis dies and constitutes a sequestrum.
Arch nearly as broad as the anterior epiphysis of the centrum.
The epiphyses of the fourth and fifth cervical vertebrae and the anterior epiphysis of the sixth cervical are fused to their respective centra, but all the other epiphyses of the vertebral column and of the pectoral limbs are free.
Inferior foramina nearly as far apart as superior and posterior epiphysis much smaller than anterior.
Other tracks took a direction of longitudinal obliquity, and then implicated both epiphysis and diaphysis.
The stoppage of the fissuring short of the epiphysis is characteristic.
It bears posteriorly a small epiphysis which is really a detached portion of the inferior arch.
Each of the other digits consists of a long metatarsal, which in the young animal has a prominent epiphysis at its distal end, and of three phalanges.
The distal end or trochlea is also formed by anepiphysis and is partially divided by a groove into two convex surfaces; it articulates with the two bones of the fore-arm, the radius and ulna.
All the bones of the digits except the distal phalanges are terminated at each end by cartilaginous epiphyses, the distal phalanx of each digit has a cartilaginous epiphysisonly on its proximal end.
The terminal phalanx of each digit has an epiphysis only at its proximal end, the others have them at both ends.
Each of the metacarpals is seen in the young animal to have its distal end formed by a prominent epiphysis, and each of the phalanges, except those bearing the claws, has a similar epiphysis at its proximal end.
The proximal end or head is evenly rounded and is formed by an epiphysisossifying from a centre different from that forming the shaft.
In the young animal the odontoid process is readily seen to ossify from a centre anterior to that forming the anterior epiphysis of the axis.
Radiogram of Fracture of lower end of Fibula, with separation of lower epiphysis of Tibia.
An epiphysis is nourished from the articular arteries and through the vessels of the periosteum.
Separation of Lower Epiphysis of Femur, with fracture of lower end of diaphysis.
It is more common, is always pathological, and is nearly always a result of fracture of the lower end of the humerus or separation of the lower humeral epiphysis and subsequent interference with growth.
When the growth of one of the bones of the leg or forearm is arrested after separation of its epiphysis while the other bone continues to grow, the foot or hand is deviated towards the side of the shorter one.
The epiphysis at the lower end of the femur may be displaced into the ham and press on the popliteal vessels.
Thus, unnatural mobility at an epiphysial junction may closely resemble movement at the adjacent joint, especially when the epiphysis is an intra-capsular one.
Injuries in the region of the upper epiphysis resulting in loss of movement, may, in the absence of a reliable history, be mistaken for tuberculous disease.
The limb usually becomes flexed and adducted, and a swelling forms in front of the joint at the upper part of Scarpa's triangle; the upper femoral epiphysis may be separated and furnish a sequestrum.
The periosteum rarely becomes separated at the line of junction of the epiphysis and diaphysis.
It is remarkable how quickly and perfectly an epiphysis may become reunited to its shaft (Figs.
Separation of lowerepiphysis of femur with marked subperiosteal hemorrhage.
As the result of the lack of bone formation and the consequent weakening of the corticalis and the spongiosa, frequently a separation of the diaphysis from the epiphysis results.
In consequence of the interference with nutrition occasioned by these changes atrophy and fatty degeneration of the cartilage-cells occur, and they form between the epiphysis and diaphysis a necrosed mass which irritates the living bone.
Suppuration is rare, disjunction of the epiphysis from the diaphysis common.
When the doses are still larger, vascularization and softening may rise to such a point as to separate the epiphysis from the diaphysis.
It should be mentioned that there is a proximal epiphysis or separate bone to the first phalange, adjacent to the pulley joint of the metacarpal bone, which is like the separate olecranon process of the ulna of the fore-arm.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "epiphysis" in a variety of sentences. We hope that you will now be able to make sentences using this word.
