1. Fracture of radius and ulna

3. Distal Radius Fracture
A distal radius fracture is a common bone fracture of the radius in the forearm. Because of its proximity to the wrist joint , this injury is often called a (wrist fracture).

4. Deformity in the Wrist

5. Associated median nerve injury
Thenar muscles paralysed.
This affects opposition of the thumb and flexion of the index and middle fingers.
Hand of benediction

6. Associated injuries Smith’s fracture: (reverse colles’ fracture)
fracture of the distal radius .
It is caused by a direct blow to the
dorsal forearm or falling onto flexed wrists.
Less common than colles’ fracture.
is a fracture of the distal radius in the forearm with dorsal (posterior) displacement of the wrist and hand
Mechanism
a fall onto a flexed wrist, OR
direct blow to the back of the wrist
Mechanism :
Falling on an outstretched hand
The characteristic appearance is
called: (garden spade deformity)
called: (dinner fork deformity)

7. Radial Head Fractures
Incidence:
radial head fractures are among the most common elbow fractures
occur in up to 20% of all elbow injuries

8. fall on outstretched hand forearm in pronated position
Mechanism of injury
fall on outstretched hand
forearm in pronated position
axial load created across elbow

9. Associated injuries.
30% have associated soft tissue or skeletal injuries including distal Radioulnar joint (DRUJ) injuries - Interosseous membrane disruption coronoid fractures
elbow dislocation
- carpal fractures

10. Radius and Ulnar Shaft Fractures
Anatomy:
The ulna acts as an axis around which the laterally
bowed
radius rotates in supination and pronation.
Interosseous membrane (IOM) : - occupies the space between the radius and ulna and comprised of 5 ligaments.

11. Mechanism direct trauma (most common) : indirect trauma :
often while protecting one's head
indirect trauma :
motor vehicle accidents
falls from height
athletic competition

12. Signs and Symptoms gross deformity. (dorsal bowing
of the radius and ulna)
2. pain, swelling
3. loss of forearm and hand function
4. Decreased sensation or inability
to move the limb, which may
indicate nerve damage

13. Associated conditions
1) Elbow injuries
evaluate DRUJ and elbow for :
A- Galeazzi fractures 
B- Monteggia fractures 
2)Compartment syndrome
evaluate compartment pressures if concern for compartment syndrome

14. Types of Fractures Galeazzi fracture Monteggia fracture
Defined as a fracture of the distal one third of the radius with dislocation of the distal radioulnar joint (DRUJ).
Monteggia fracture
Defined as a fracture of the ulna (usually proximal one third) with dislocation of the radial head.
Greenstick fracture
Fracture on one side of the bone, causing a bend on the other side of the bone.

15. Galeazzi fracture

16. Neurovascular injury - uncommon except
PIN injury with Monteggia fxs and Henry (volar) approach to middle and upper third radial diaphysis
