Fractures

"Apakah (akan dibangkitkan juga) apabila kami telah menjadi tulang belulang yang hancur lumat?"
Mereka berkata: "Kalau demikian, itu adalah suatu pengembalian yang merugikan."
Sesungguhnya pengembalian itu hanyalah satu kali tiupan saja, maka dengan serta merta mereka hidup kembali di permukaan bumi.
(An-Naazi'at : 11-14)

Assalamualaikum buat semua pembaca,

Entri ini saya hasilkan hanya untuk memudahkan rujukan saya tentang sebahagian daripada topik fractures, yang saya copy paste daripada page facebook Dentistry---طب الأسنان .

Midface Fractures
>>le Fort Type 1
  • horizontal maxillary fracture.
  • fracture line passes through the alveolar ridge, lateral nose and inferior wall of maxillary sinus.
>>le Fort Type 2
  • pyramidal fracture
  • fracture arch passes through posterior alveolar ridge, medial orbital rim and nasal bones.
>>le Fort Type 3
  • craniofacial disjunction
  • fracture line passes through nasofrontal suture, maxillo-frontal suture , orbital wall and zygomatic arch.

Mandibular fractures

We can classify the mandibular fractures according to :

1- anatomical distribution of mandibular fractures (figure 1)
figure 1

2- according to extent of injury (figure 2)

A- Simple Fracture. A simple fracture is a break in the bone that does not produce an open wound in the skin. A simple fracture can be complete (complete severance of the bone) or incomplete. Tissue adjacent to the fracture may or may not suffer considerable injury.

B- Greenstick fracture is one in which one side of the bone is broken and the other side is bent.

C- Compound Fracture. A compound fracture is a break in the bone with an external wound extending to the bone. Communication from the bone to the skin or other covering surface is an invitation for contamination.

D- Comminuted Fracture. A comminuted fracture is one in which the bone is splintered into three or more fragments or is crushed.

NOTE: A compound-comminuted fracture is one with both a splintering of the bone and a break in the bone with an opening to the covering surface.

3- favorable and unfavorable mandibular fracture

Favorable Fracture.
A favorable fracture is when the line of the fracture occurs in a direction that does not allow the pull of the muscles on the segments to displace the segments.

Unfavorable Fracture. An unfavorable fracture is a fracture with displacement or separation of the fractured segments due to muscle pull on the segments.
