Novel cemented cup-holding technique while performing total hip arthroplasty with navigation system.

Area of Science:

• Orthopedic Surgery
• Surgical Navigation
• Arthroplasty

Background:

• Navigation systems are increasingly used in total hip arthroplasty.
• Existing navigation systems primarily support cementless acetabular components.
• Cemented total hip arthroplasty often requires specialized equipment for navigation.

Purpose of the Study:

• To propose a novel, accessible technique for utilizing navigation systems in cemented total hip arthroplasty.
• To adapt existing surgical tools for navigated cemented acetabular component placement.
• To enable surgeons performing cemented hip arthroplasty to benefit from navigation technology.

Main Methods:

• A novel cemented cup-holding technique was developed.
• The technique combines a standard cementless cup holder with an inverted cementless trial cup.
• This adapted apparatus functions as a holder for cemented acetabular components within a navigation system.

Main Results:

• The proposed upside-down cup-holding technique is effective for navigated cemented acetabular component placement.
• Readily available surgical articles can be combined to create the necessary holder.
• The technique provides a viable solution for surgeons using cemented techniques with navigation.

Conclusions:

• The novel technique successfully allows for the use of navigation systems in cemented total hip arthroplasty.
• This method offers a practical and cost-effective alternative to specialized holders.
• It expands the applicability of surgical navigation to a broader range of hip arthroplasty procedures.
