Instructions
  • Precautions
1. Before using this product, the user must carefully read the "Orthopedic Internal Fixation" and related materials recommended by the AO organization, and be proficient in the operation of this product, and should strictly follow the instructions for use. 

2. Transport and store the implant carefully. Crashing, bending or scratching the implant will significantly reduce the strength and fatigue life of the implant, and will cause the implant to break. If the implant is found to be deformed before use, stop using it. 

3. Implants of different specifications must be prepared during the operation. It is extremely important to correctly choose the implant during the operation. If the size of the implant is selected, the success rate of the operation will increase. Conversely, incorrect selection, installation, positioning, and fixation can cause abnormal pressure and shorten the life of the implant. 

4. The implant is a device used to bear the load and maintain the orthopedic sequence until the normal physiological structure is formed. If the formation of the normal physiological structure is delayed or does not heal, the implant will bear additional and repeated loads, which will eventually lead to the implant loosening, bending, fatigue fracture, etc.

5. X-ray examinations should be done regularly in the first year after surgery, and careful comparisons should be made to check whether there is any change in the position of the implant, loosening, bending, breaking, and signs of delayed healing or non-union. If these signs appear, the patient needs to be closely observed to assess the possibility of further deterioration, and consider reducing activities or even early repair.

6.Carefully advise the patient that postoperative care and the patient's willingness and ability to follow the doctor's advice are two important factors for successful fracture healing. It is especially important for the treatment of unstable fractures, to make the patient realize that the restriction of the implant and physical activity and bearing weight may cause the implant to loosen，bend and break before the bone heals. Patients should also understand that metal implants are not as tough as normal healthy bones, and that implants cannot restore the flexibility, strength, reliability, or durability of bones as normal bones. Before the bones are fully healed, even under normal stress and weight bearing conditions, fractures will occur and cause the need to be replaced later. Patients can not move frequently and are too tired, and uncooperative patients should limit their activities appropriately. Smoking patients should be informed that smoking will increase the incidence of bone graft non-fusion.

7. After the bones are completely healed, the implants will also loosen, break, and corrode. Therefore, one year after the operation, the X-ray shows that the fracture is completely healed, and the implants can be taken out. Failure to take it for more than 1.5 years may cause the following complications: implant failure, corrosion, soft tissue reaction or pain, displacement causing damage to soft tissue, internal organs, nerves and joints; postoperative trauma, causing additional risk of injury ; Difficult to remove the implant, pain or uncomfortable sensation caused by the presence of the implant in the body; increase the risk of infection and reduce the bone's due capacity. 

8.When removing the implant, the risks of the second operation should be considered. Therefore, before the operation, preparations should be made to prevent another fracture. 

9.Reduce bone fragments as much as possible, involving joint fractures, and restore the integrity of the articular surface. 10.If the fracture is accompanied by severe soft tissue swelling or extensive skin contusion, these complications should be cured first, and then a second-stage open reduction and fixation should be performed.
