USEFULNESS OF HIPCOMPASS AND TARGET IN THA

The International Society for Technology in Arthroplasty (ISTA), 28th Annual Congress. PART 2.



Abstract

Introduction

Accurate acetabular cup orientation could lead to successful surgical results in total hip arthroplasty (THA). We introduce a novel CT-based three-dimensional (3D) planning system, HipCOMPASS (Fg.1) and TARGET (Fig.2), which enable to design suitable alignment not only cup also surgical devices calculatingly, according to each pelvic inclination.

Patients and methods

We performed THA in 13 patients (10 female and 3 men) between September 2014 and April 2014. Average age were 67 years old. THA operation was based on each parameter of the cup and device, providing a preoperative planning by ZedView system. HipCOMPASS and TARGET is linked with ZedView software, which is simultaneously calibrated adjustable parameters on this devices. Cup alignment was assessed by ZedView as well.

Result

The differences of component alignment from the preoperative planning were shown in table.

Conclusion

HipCOMPASS and TARGET might be more accurate than conventional method and more accessible system than navigation system in THA.
