Open Vs Closed
Open ( “open to the air”)A fracture in which bone penetrates through the skin . Look out for an open wound/soft tissue laceration.
Closed Fracture with intact overlying skin.

Location
Can be described in many ways;1. Segmental (long bones)Epiphysis, Metaphysis, Diaphysis2. Thirds (long bones)Proximal 1/3, Middle 1/3, Distal 1/33. Anatomical landmarks Head, Neck, Body, Condyle, Base

Simple Fracture; A fracture that consists of the bone breaking into 2 fragments
Oblique (Metartarsal)Transverse (Tibia)
The fracture passes at an angle oblique (> 30o) to the shaft of the long bone
The fracture passes at right angles/<30o to the shaft of the long
bone

Simple spiral FractureThis fracture of
the tibia resulted from a twisting
injury.The fracture line spirals along the shaft of the long
bone

Comminuted
A bone injury that results in >2 separate components is known
as a commented fracture. This is also
known as a multi-fragmentary fracture.
Proximal humeral shaft

Fracture Displacement
Displacement of fractures is defined in terms of the abnormal position of the distal fracture fragment in relation to the proximal bone.Types of displacement include-1. Angulation2. Rotation3. Shortening4. Impaction and Distraction
![Page 11: FRACTURES By Mahima Charan 4th Year Medical Student](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d015503460f949d3276/html5/thumbnails/11.jpg)
Angulation and Rotation
To describe fracture angulation the direction of the distal bone and degree of
angulation in relation to the proximal bone should be stated.
Medial angulation can be termed ‘varus’ and lateral angulation ‘valgus’
Rotation of a long bone may be internal or external
![Page 12: FRACTURES By Mahima Charan 4th Year Medical Student](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d015503460f949d3276/html5/thumbnails/12.jpg)
The fracture on the left has resulted in angulation of the distal component.
The fracture on the right has resulted in rotation of the distal component
![Page 13: FRACTURES By Mahima Charan 4th Year Medical Student](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d015503460f949d3276/html5/thumbnails/13.jpg)
ShorteningProximal migration of the distal fracture component results in shortening of the overall bone length. An oblique fracture is more readily shortened than a transverse fracture, which would need to be fully 'off-ended' before it can shorten.The fracture on the left is displaced without shorteningThe fracture on the right is both displaced and shortened
![Page 14: FRACTURES By Mahima Charan 4th Year Medical Student](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d015503460f949d3276/html5/thumbnails/14.jpg)
Impaction and Distraction
A fracture resulting in increased overall bone length, is due to distraction (widening) of the bone components.If there is shortening of bone without loss of alignment, the fracture is impacted. The bone substance of each component is driven into the other.
The left image shows fracture widening or distraction.The right image shows a line of increased density due to fracture impaction.

Let’s have a look at some common fractures…..

Humeral fracture

ElbowThe lateral image shows the anterior
fat lad is raised way from the
humerus but does not show a fracture.
Posterior fat pad visible- ALWAYS
ABNORMALA fracture of the
radial head is visible on the AP
image

Monteggia vs Galeazzi
A Monteggia injury; fracture of the ulna shaft with dislocation of the radial head at the elbow. The radiocapitellar line should pass through the midline of the capitulum of the
humerus.
A Galeazzi injury is a fracture of the radial shaft with dislocation of the ulna from its articulation with the radius at
the distal radio-ulnar joint.

Colles Fracture
Common injury in elderly people with low bone density.Classically the injury comprises a transverse fracture of the distal radius with dorsal displacement and shortening of the wrist.
The fracture is often accompanied by a fracture of the ulnar styloid.Classical presentation is “Fall on an outstretched hand”

Garden Classification for NOF Fractures
If displaced, may present with shortened and
externally rotated leg!

Avascular Necrosis (greater risk in intracapsular fractures
and scaphoid fractures ( tenderness in anatomical snuffbox)

Principles of Management
I. First aid- If open ( clean wound, debride, tetanus injection)Analgesia for pain associated with fracture
II. Immobilise (traction, splints, casts)III. Reduction ( if displaced)
IV. Active Rehabilitation
DON’T FORGET YOU NEED 2 VIEWS ON AN XRAY!
