What is meant by tripod fracture?

The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components, three of which are directly related to connections between the zygoma and the face, and the fourth being an orbital blowout.

What is the geological definition of fracture?

A fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces.

What are the two main types of fracture geology?

Summary. Depending on the relative displacement across the fracture plane, all tectonic fractures are of two main mechanical types: extension fractures and shear fractures.

What are fractures in rocks called?

If rocks on one side of the break shift relative to rocks on the other side, then the fracture is a fault. If there is no movement of one side relative to the other, and if there are many other fractures with the same orientation, then the fractures are called joints.

What bones are in a tripod fracture?

Zygomaticomaxillary complex (ZMC) fractures, also known as tripod, tetrapod, quadripod, malar or trimalar fractures, are seen in the setting of traumatic injury to the face….They comprise fractures of the:

zygomatic arch.
inferior orbital rim, and anterior and posterior maxillary sinus walls.
lateral orbital rim.

Where is a tripod fracture located?

They are the second most common facial bone fracture after nasal bone injuries. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma.

What is the fracture of igneous rocks?

Fractures formed in igneous rocks during the later diagene- sis refer to fractures caused by various geneses mechanism and occurrences due to supergene geological processes, deeper hydrothermal fluids, organic acid and metasomatic minerals. They often formed with tectonic fractures. the fractures and carbonate cement.

What is the difference between fault and fracture?

Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. Fractures are simply cracks in the crust where there is no movement. Faults are classified according to the direction of relative movement along the fault.

What is Gillies approach?

Temporal (Gillies) approach – Skin incision The Gillies technique describes a temporal incision (2 cm in length), made 2.5 cm superior and anterior to the helix, within the hairline. A temporal incision is made. Care is taken to avoid the superficial temporal artery.
