2. Neck of femur fracture. N eck of femur fractures, or femoral neck fractures, are common injuries sustained by older people. Elderly osteoporotic women are at greatest risk . The femoral neck is the weakest part of the femur.

3. Disruption of blood supply to the femoral head is dependent on the type of fracture and causes significant morbidity. The diagnosis and classification of these fractures is important. There are three types : Subcapital : Femoral head/neck junction. Transcervical : Midportion of femoral neck. Basicervical /lateral femoral neck: Base of femoral neck.

4. Plain radiograph is the first-line investigation. In patients with a suspected occult neck of femur fracture, MRI (sensitivity 99-100%) CT or nuclear medicine bone scan third-line . There is some evidence that thin-slice MDCT is as sensitive as MRI

5. Plain radiograph Shenton’s line disruption: loss of contour between normally continuous line from medial edge of femoral neck and inferior edge of the superior pubic ramus Lesser trochanter is more prominent due to external rotation of femur Asymmetry of bilateral femoral neck/head Non-displaced fractures may be subtle on x-ray

6. X ray pelvis A/P

7. X ray hip A\P and lateral view.

8. X ray pelvis A/P and x ray hip oblique view.

9. Coronal T1 and Axial T1 view: Sub capital right femur neck fracture with adjacent soft tissue injury.

10. Classification of fracture.

11. Fracture: Break in continuity of bone which may be either complete or incomplete. Classifications: There are 3 types of classification Etiological Clinical Radiological.

12. Radiological

13. AP and lateral radiographs of the forearm show a partial fracture with mild angulation through the distal ulna and proximal radius..

14. AP and lateral radiographs of the forearm show bending of radius without cortical disruption.

15. Torus fracture of the radius The cortex is buckled on the dorsal surface Apart from minor plastic.

16. Classification of fracture according to fracture line:

17. An oblique fracture of the proximal phalanx of the fourth digit. There is minimal override of the fracture fragments

18. Spiral fracture. AP projection of the leg demonstrates a spiral fracture of the tibia. Note the sharp ends of the fracture fragments (arrows )

19. Growth plate injury classification:

20. Le fort fracture classification. Type 1 :horizontal maxillary fracture, separating the teeth from the upper face fracture line passes through the alveolar ridge, lateral nose and inferior wall of the maxillary sinus.

21. Type 2 : pyramidal fracture, with the teeth at the pyramid base, and nasofrontal suture at its apex .Fracture arch passes through the posterior alveolar ridge, lateral walls of maxillary sinuses, inferior orbital rim and nasal bones. Uppermost fracture line can pass through the nasofrontal junction or the frontal process of the maxilla.

22. Type 3 :Craniofacial disjunction occur here. Transverse fracture line passes through nasofrontal suture, maxillo -frontal suture, orbital walls, and zygomatic arch/ zygomaticofrontal suture
