Imaging Analysis of Prosthesis Angle after Hip Replacement with Direct Anterior Approach in Lateral Position

The use of lateral DAA-THA for the treatment of end-stage hip disorders has good recent clinical efficacy, does not require special surgical beds and traction equipment, uses traditional surgical instruments, reduces the requirements for surgical beds and surgical instruments, enters through the nerve and muscle anatomical gap without cutting any muscle or nerve tissue, is minimally invasive, and has good surgical maneuverability, low bleeding, low postoperative pain, short hospitalization time, and rapid recovery. It is a safe and effective minimally invasive procedure because of its light weight, short hospital stay, and rapid recovery. In this paper, we used imaging to observe the angle of the posterior prosthesis. And the results showed that hip arthroplasty using the direct anterior approach improved hip mobility in early stages compared with other approaches and reduced pain. The direct anterior approach and length between total hip arthroplasty using direct lateral and posterior lateral approach and partial data (surgical time, blood loss, etc.) were significantly worse than those using direct forward approach. In addition, the direct anterior approach to total hip arthroplasty is subject to a learning curve and requires at least 33 cases of experience to achieve a lower complication rate.
