Orthopedic Intelligent Navigation System in the Treatment of Fresh Femoral Neck Fractures

Prospective, Multicenter, Randomized Controlled Clinical Study of Orthopedic Intelligent Navigation System in the Treatment of Fresh Femoral Neck Fractures

The goal of this clinical trial is to verify the safety and effectiveness of orthopaedic surgical navigation system in the treatment of fresh femoral neck fractures.

Participants will:

2. The patient is known to have a history of allergy to one or more implanted materials;
3. Patients determined by researchers to be physically weak or unable to tolerate surgery due to other systemic diseases;
4. Active infection of the hip joint or other parts of the body is determined by the investigator;
5. Diagnosed as metabolic bone disease, radiation bone disease, etc.;
6. Severe hip contracture deformity or severe muscle loss fused to the functional position for a long time without pain;
7. have inflammatory arthritis, such as rheumatoid arthritis, systemic lupus erythematosus arthritis, ankylosing spondylitis, etc.;
