Description
Objectives: To evaluate the clinical and radiological postoperative results of Total Hip Arthroplasty with the RI HIP NAVIGATION system.
Methods: 90 patients underwent total hip arthroplasty using the RI HIP NAVIGATION system. The range of pain improvement, accuracy of leg length correction, range of motion, time to return to activities and any complication were analyzed. Clinical evaluation was performed using the OXFORD HIP score, pain was assessed with the VAS scale, and quality of life was assessed with the SF-12. Radiological evaluation consisted of plain radiographs.
Results: There were a total of 47 women (52%) and 43 men (48%), with a mean age of 69 years (range 37-88). Patients were mobilized within 10.5 hours (range 7-13 hours) after surgery and the mean hospital stay was 2 days (range 1-3 days). There was a significant improvement in pain and functional status immediately postoperatively, while the restoration of the leg-length was complete. Eleven (12%) patients were transfused with a mean of 1IU. Patients' overall quality of life was significantly better for both SF-12 parameters. All the patients returned immediately to their homes without the need for further physical therapy.
Conclusions: The RI HIP NAVIGATION system can provide excellent functional and clinical results even immediately postoperatively. The restoration of hip length and kinematics is absolutely accurate, blood loss is minimal, soft tissue balancing is ideal, and postoperative pain is minimal. In addition, by calculating the pelvic tilt, the dimensions of the pelvis and the 3D mapping of the acetabulum, the risk of sub-optimal placement of the implants is reduced to a minimum.
