Computed tomography-based surgical navigation for hip arthroplasty.
Component malpositioning and postoperative leg length discrepancy are the most common technical problems associated with total hip arthroplasty (THA). Surgical navigation offers the potential to reduce the incidence of these problems. We reviewed 317 patients (344 hips) that underwent THA using computed tomography-based surgical navigation, including 112 THAs using a simplified method of measur...
متن کاملNavigation for total hip arthroplasty
Despite increasing advantages in biomaterials, prosthetic designs, and implant fixation, clinical outcome of total hip arthroplasty (THA) has 10% failure rate after 10 years. Component malposition is well known to be responsible for instability, impingement, excessive wear and early loosening. Computer-assisted procedures are expected to improve the accuracy of the components positioning and al...
متن کاملComputed tomography in evaluation of revision hip arthroplasty outcomes.
Background. This study aimed to assess contact between Recon Shell reinforcement cages used in revision hip arthroplasty and the bony base. Radiographic examinations were performed with the use of multi-energy computed tomography. Material and methods. We tentatively assess the fixation of Burch-Schneider reinforcement cages (Recon Shell made by Aesculap company) implanted in 10 patients, using...
متن کاملDoes degree of the pelvic deformity affect the accuracy of computed tomography-based hip navigation?
Although some navigation systems have been used for improvement of component positioning, there have been few reports regarding cases of severe pelvic deformity. We performed a retrospective review of 25 cases of total hip arthroplasty with a computed tomography-based navigation system in patients with severe pelvic deformities and estimated acetabular component position and angle between sever...
متن کاملMinimal-Dose Computed Tomography for Measurement of Cup Orientation in Total Hip Arthroplasty
Introduction: Accurate assessment of cup orientation is important for evaluation of outcome after total hip arthroplasty (THA). The orientation is clinically described as a combination of inclination angle and version angle. Measurements of these angles based on plane radiographs are inaccurate, because no solution exists for perfect positioning of the pelvis, as Liaw(1) stated. Computed tomogr...
