Abstract:

The number of total hip arthroplasty is increasing year by year. With the progress of surgical techniques and prosthesis design, hip arthroplasty is becoming more and more popular. However, intraoperative and postoperative complications, including leg length discrepancy, dislocation, fracture, nerve injury, prosthesis loosening and infection, are still the main problems. Faster rehabilitation, better postoperative function, shorter operation time and longer prosthesis service time are still the current goals. It is an effective method to recover the biomechanics of hip including femoral offset and lower limb length through good preoperative planning and intraoperation implementation. Preoperative planning has experienced the evolution process from X-ray based on acetate film template to digital two-dimensional template, and then to three-dimensional preoperative planning. Compared with CT examination, X-ray film has obvious deficiencies in the evaluation of hip detail morphology. CT based on 3D evaluation can optimize the selection of prosthesis position and size, and predict the difficulty of surgery. Preoperative planning combined with intraoperative navigation and surgical robot system plays an increasingly important role in the quality control of total hip arthroplasty in recent years.

Key words: Arthroplasty, replacement, hip, X-ray film, Tomography, X-ray computed
