Ch. 12 Fractures (Part 2)

2. Most serious. No healing due to lack of vascularization
3. fx occurs at maximum strain on a bone (March fx)
4. fx of proximal ulna and dislocation of radial head
5. fx of both ankle malleoli w/ dislocation of ankle joint
7. only part of bone fractures with little or no displacement
9. fx heals in faulty position impairing function or cosmetic appearance
10. 5th metacarpal fx
11. severe ankle sprain or tibial fracture w/ a fx of the proximal fibula
15. classification for long bone injuries involving the growth plate
18. fx that penetrates the skin
19. when bone ends jammed together
20. Distal end of radius fx (dinnerfork deformity)
21. fx results from a direct blow to the front of the orbit that transfers force to the orbital walls and floor

1. Reverse Colles: palmer displacement
2. complete; Bone separates into two fragments
3. radiographic fx signs
6. fx with fragmented bone
8. simple fx; no penetration of skin
12. fx of 1st carpometacarpal joint
13. fx occurs at proximal radius w/ a dislocation of the distal radial-ulnar joint
14. fx of all three sutures (Frontal, temporal, maxillary (Facial Disfigurement)
16. fx occurs where piece of bone is pulled away from shaft
17. fx occurs from repetitive motion
22. fx gives clinical signs w/o x-ray evidence
