Value of computed tomography-based three-dimensional surgical preoperative planning software in total hip arthroplasty with developmental dysplasia of the hip

Periprosthetic Occult Fractures of the Acetabulum Occur Frequently During Primary THA

“…As part of other study protocols that obtained preoperative and postoperative CT images on a large number of primary THAs for templating and computer navigation purposes [10,[14][15][16]18], we routinely recognized postoperative acetabular fractures on these images and thought that the incidence of these fractures was unexpectedly high. Previous reports have indicated that underreaming or oversizing the cup (insertion in rigid bone), osteoporosis, and a preoperative diagnosis of rheumatoid arthritis were risk factors for periprosthetic fractures of the acetabulum which were detected during surgery and with postoperative radiographs [6,7,14,20,30].…”

The correlation between clinical radiological outcome and contact state of implant and femur using three-dimensional templating software in cementless total hip arthroplasty

“…Considering with this report, a subjective decision of fit and fill parameters by using plain radiograph may be likely to influence the correlation between femoral fit and radiological outcomes. Recent studies have expanded the use of CT-based three-dimensional templating to establish the contact state of implant and femur, to achieve more precise preoperative planning and to evaluate the implant insertion state [20][21][22].…”

Clinical Results of Total Hip Arthroplasty in Two Patients with Charcot Hip Joints due to Congenital Insensivity to Pain with Anhydrosis

“…First, we used large femoral heads to reduce the risk of postoperative dislocation, with highly cross-linked polyethylene liners to reduce polyethylene wear. Next, we used CT-based three-dimensional templating software to select a femoral stem which achieved appropriate stem anteversion and femoral offset [5]. Third, we performed the surgery utilizing a CT-based navigation system to reproduce preoperative planning as closely as possible [11].…”

“…The authors performed the preoperative planning using a CT-based navigation system (Stryker Inc., Mahwah, NJ) in both cases, as detailed in our previous study [5]. Stem anteversion was determined in accordance with preoperative femoral anteversion.…”
