1. The calcaneus projects backward behind the ankle.

2. A reducing fixing device for fracture of calcaneus belongs to the medicine equipment field.

3. Calcaneus the bone fracture is the clinical most common one kind of tarsal bone bone fracture, approximately composes the complete tarsal bone bone fracture 60%.

4. Conclusion For the calcaneus fracture involving the joint face the function of the foot can be better restored only through restoring the anatomical construction of joint face.

5. Fractures of the calcaneus are the most common type of tarsal bone injuries, and about 75% of total calcaneal fractures are intraarticular.

6. Metheds 31 cases with trauma of tendo calcaneus were examined with high frequency ultrasound.

7. Results High frequency ultrasound could confirm trauma of tendo calcaneus.

8. The Achilles tendon that connects with soleus, gastrocnemius muscle and calcaneus behaves like a "three stings system".

9. Methods: 24 cases ( 27 feets ) of collapsed calcaneus fractures were treated calcaneus Ti - plate and synthetic bone grafting.

10. The information indicates that all of the patients are treated by the calcaneus traction combining with manipulation diaplasis, outside fastening with little splints and Chinese traditional medicines.

11. Objective: To investigate the better method for the treatment of calcaneus fracture affected with talocalcaneal joint.

12. Conclution High frequency ultrasound may be the first choice to diagnose trauma of tendo calcaneus.

13. The effect of open reduction and internal fixation for treatment of intra - articles calcaneus fracture is satisfactory.

14. To evaluate our protocol with the extensile lateral approach to open reduction and internal fixation in the treatment of displaced intra-articular calcaneus fractures.

15. Objective To evaluate the value of high frequency ultrasound in diagnosis of trauma of tendo calcaneus.

16. Methods 18 cases of calcanodynia were received comprehensive surgical therapy, including resection of bone spur,(http://) lysis of plantar fascia and decompression by drilling in calcaneus.

17. Conclusion Calcaneal plate internal fixation treatment has a better curative effect on calcaneus fractures.

18. Objective To evaluate the effects of allogenous bone graft of the compressed calcaneus fracture.

19. Operation is the only therapeutic method to solve some problems in treating malunion after fracture of calcaneus.
