MECHANISM OF INJURY (HOW IT HAPPENED, OR WHY IT HAPPENED)
An injury is either functional or structural An injury can be caused by tension
(stretching), compression, shearing, or bending

STRUCTURAL
A structural injury is caused by excessive stress on the bone, by lengthened or shortened tissue, or overuse of a muscle/ tissue
![Page 4: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/4.jpg)
EXAMPLES OF A STRUCTURAL INJURY
Claw Toes Hammer Toes Damage to the Accesory Navicular Morton’s Neuroma Hallux Valgus
![Page 5: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/5.jpg)
CLAW TOES
This happens when flexor digitorum brevis ( a muscle that connects to the middle phalanx of the toes) over powers the rest of the 5 foot muscles. This causes extension of the middle phalanx, and flexion of the proximal phalanx/ Distal interphalangeal joint

HAMMER TOES
A hammer toe is a toe that is flexed at the proximal interphalangeal joint, and extenstion of the metatarsophalangeal joint
There are 2 classifications of hammer toes: flexible and rigid
Flexible hammer toes are moveable, and can be straightened manually
Rigid hammer toes doesn’t have this ability; movement can be very painful

MORTON’S NEUROMA
This is an enlarged nerve that runs between the 1st and 2nd metatarsals, and the 3rd and 4th metatarsals
![Page 8: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/8.jpg)
HALLUX VALGUS
This is commonly associated with bunions Normally occurs in the first metatarsal (big
toe) when it deviates inward
![Page 9: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/9.jpg)
FUNCTIONAL
These injuries can be pre-disposed There are two stages: acute and chronic This could be related to the structure of the
injured area Fractures are the main type of Functional
injuries
![Page 10: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/10.jpg)
FRACTURES
In a fracture, a bone is either cracked or broken
Many types of Fractures– simple, transverse, oblique, spiral, comminuted, segmental, avulsed, and impacted
The only treatment for these injuries is immoblization of the area and rest

SIMPLE FRACTURE
A simple fracture is one that doesn’t break the skin; also known as a closed fracture.
There may be bruising and swelling, but no obvious signs of a fracture
![Page 12: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/12.jpg)
TRANSVERSE FRACTURE
A fracture that occurs straight across the bone
![Page 13: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/13.jpg)
OBLIQUE FRACTURE
Broken at an angle across the bone Usually a result of a sharp, angled blow to
the area
![Page 14: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/14.jpg)
SPIRAL FRACTURE
A fracture where the bone has been twisted apart
Also known as a “torsion fracture” Can happen when a foot is planted, and the
leg twists
![Page 15: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/15.jpg)
COMMINUTED FRACTURE
A fracture where the bone is completely crushed
This is a very hard thing to correct, because the bone is in many pieces
![Page 16: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/16.jpg)
SEGMENTAL FRACTURE
A fracture where the bone is in many different pieces
There are multiple fractures on the same bone
![Page 17: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/17.jpg)
AVULSED FRACTURE
An injury to the bone where a ligament or tendon attaches
When this occurs, the ligament or tendon pulls of a piece of the bone, resulting in a fracture.
![Page 18: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/18.jpg)
IMPACTED FRACTURE
Also known as a “greenstick fracture” The bone “splinters” like a young green limb
from a tree or bush It doesn’t completely break
![Page 19: F OOT, AND A NKLE An overview of how and why injuries occur, how to help prevent them, and how to treat them. By Mattie Weber](https://reader035.vdocument.in/reader035/viewer/2022062802/56649ea75503460f94ba9ea1/html5/thumbnails/19.jpg)
STRESS FRACTURES
These occur from over use of a boneMost common in repetative motion sports
(running, soccer, softball, baseball, etc)Occurs where the bone changes density or
shapeThe only way to treat this is rest and
immoblization
