Templating for Total Hip Arthroplasty in the Modern Age

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Biomedical Engineering

Background:

• Preoperative templating is crucial for optimizing implant selection and surgical workflow in total hip arthroplasty (THA).
• Accurate templating minimizes complications like leg length inequality, impingement, wear, dislocation, and fracture, enhancing patient satisfaction.
• Technological advancements in imaging are enabling more precise preoperative planning.

Purpose of the Study:

• To review the fundamentals of preoperative templating for THA.
• To emphasize the incorporation of patient-specific pelvic motion analysis into preoperative planning.
• To highlight the implementation of three-dimensional (3D) templating in surgical practice.

Main Methods:

• Review of current literature on preoperative templating techniques in THA.
• Discussion of advancements in preoperative imaging, including 2D to 3D radiographs, biplanar low-dose radiographs, and CT scans with 3D reconstructions.
• Exploration of how patient-specific pelvic motion influences component placement and bearing selection.

Main Results:

• Enhanced understanding of patient-specific pelvic motion allows for proactive management of lumbar pathology risks.
• 3D templating provides a more comprehensive approach to preoperative planning compared to traditional methods.
• Improved implant selection and sizing lead to optimized surgical workflow and efficient care delivery.

Conclusions:

• Preoperative templating is essential for successful THA, benefiting patients, surgeons, and hospitals.
• Integrating patient-specific pelvic motion and 3D templating into practice can significantly improve surgical outcomes and reduce complications.
• Continued adoption of advanced imaging technologies is key to advancing THA preoperative planning.
