FOOSH is an acronym for fall onto an outstretched hand.
A number of injuries of the upper limb occur because of fall onto the outstretched hand.
Hence commonly these are called FOOSH injuries.
Common Injuries Caused by FOOSH
Here are the injuries that may occur due to FOOSH
- Fracture of the clavicle
- Fracture proximal humerus
- Supracondylar fracture of the humerus
- Fracture of the head and neck of the radius
- Monteggia fracture-dislocation
- Galeazzi fracture-dislocation
- Colles’ fracture
- Radial styloid fracture
- Fracture of the scaphoid
- Fracture of the triquetral
- Bennetts fracture/Reverse Bennet Fracture
- Ulnar collateral ligament injury
Clavicle fractures are the most common upper limb fractures They account for about 35% injuries to the shoulder girdle and 2.6% – 4% of all adult fractures
Clavicular fractures are also caused by motor vehicle accidents and when a person falls directly on the shoulder with the arm at the side.
A direct blow or from a fall on an outstretched hand are less common causes.
Proximal Humerus Fracture
A similar injury in young people may result in the shoulder dislocation.
Depending on the severity of the injury, the fracture may be undisplaced or displaced. The distal fragment of bone is moved backwards and is tilted, although very rarely it is displaced anteriorly. Displaced fractures could injure nerves and vessels in the vicinity.
Radial Head Fracture
In adults, there is more likelihood of injuring the radial head. But in children, the radial neck is generally fractured.
There is also likely to be bruising or chipping of the articular cartilage of the capitulum.
Galeazzi Fracture and Monteggia Fracture
The Galeazzi fracture-dislocation is:
It is often caused by on an outstretched hand, probably with an element of rotation. The condition may be regarded as a mirror image of a Monteggia fracture which is a fracture of ulna and dislocation of the radial head.
Distal Radius Fracture
Carpal Bone Injuries
Also, the fall on the outstretched hand can lead to a ligamentous injury leading to wrist instability.
Features of FOOSH Injuries
Fall onto an outstretched hand occurs following sporting injuries, or simply after a fall.
Typically, these injuries have bimodal age and sex presentation.
- Young patients – high energy trauma
- Older patients – lower energy, e.g. simple fall
