device. |

A posterior curvature of the thoracic spine |
| Lasso |
An image editing tool that enables you to
select an irregular object by dragging the mouse around it (while the mouse
button is held down) and letting go. You do not have to join the ends
together. When the mouse button is released, the two ends are connected
automatically. |

That part of the skeleton of the hind or lower
limb between the tarsus and phalanges; metatarse. It consists, in the human
foot, of five bones |
| MRI |
A special imaging technique used to image
internal structures of the body. It uses the influence of a large magnet to
polarize hydrogen atoms in the tissues and then monitors the summation of the
spinning energies within living cells. |
| Nails |
Afixation device introduced into the medullary
canal of a long bone |
| Offset |
The anatomic distance between the center of
femoral head and the middle of the femoral canal. |
| Ossified |
Ossification is the process of bone maturity
where cartilage changes to firm solid bone |
| Osteotomy |
A surgical procedure involving cutting of a
bone. |
| PACS |
In medical imaging, picture archiving and
communication systems (PACS) are computers or networks dedicated to the
storage, retrieval, distribution and presentation of images. |
| Pediatric orthopedic |
A field in orthopedic surgery dealing with
typical orthopedic problems at young age and immature skeleton - among these
problems: various deformities |
| Plates |
A flat, or nearly flat, piece of metal used to
fix fractured bone fragments |
| Query |
To
interrogate a collection of data such as records in a database. The term may
also be used to search a single file or collection of files. DICOM Query can
be done between a PACS and an application on a device. |
| Retrieve |
To call up data that has been stored in a
computer system. When a user queries a database, the data are retrieved into
the computer first and then transmitted to the screen. DICOM Retrieve can be
done between a PACS and an application on a device. |
| Retrograde |
Direction from the bottom of a bone upwards
(Used to define the direction in which an intramedulary nail is inserted) |
| Sagittal Plane |
The longitudinal vertical plane that divides
the anatomical region into two parts (left and right.) |
| Scoliosis |
A congenital lateral curvature of the spine. |
| Screw |
A kind of nail with a spiral thread and a head
with a nick to receive the end of the screw-driver. Screws are much used to
hold together pieces of broken bone or to fasten something. |
| Series |
Part of PACS architecture: A series is a
collection of images, usually relevant to an anatomic location or object.
Such as two views (AP & LAT) of the same region of interest. |
