Measuring acetabular component version after THA: CT or plain radiograph?
BACKGROUND Although cross-table lateral radiographs are commonly used to measure acetabular component version after THA, recent studies suggest that CT-based measurement is more accurate. This has been attributed to variations in pelvic tilt, pelvic rotation, and component inclination. Furthermore, it has been suggested, based on limited data, that even with ideal positioning of the cross-table...
متن کاملFluoroscopic imaging of acetabular cup position during THA through a direct anterior approach.
Mobile image intensifiers are more readily used to assess acetabular cup placement when performing a total hip arthroplasty through a direct anterior approach. However, patient positioning affects pelvic tilt and rotation, which in turn requires proper C-arm fluoroscopy adjustments for image interpretation. The authors provide insight into the interpretation of acetabular cup positioning based ...
متن کاملComparison of robotic-assisted and conventional acetabular cup placement in THA: a matched-pair controlled study.
BACKGROUND Improper acetabular component orientation in THA has been associated with increased dislocation rates, component impingement, bearing surface wear, and a greater likelihood of revision. Therefore, any reasonable steps to improve acetabular component orientation should be considered and explored. QUESTIONS/PURPOSES We therefore sought to compare THA with a robotic-assisted posterior...
متن کاملFluoroscopic Imaging of Acetabular Cup Position During THA Through a Direct Anterior Approach
Two main causes of postoperative total hip arthroplasty (THA) dislocation are malposition of the acetabular component within the prosthesis and soft tissue imbalances.1 The direct anterior approach for THA is viewed as advantageous compared with other approaches because, in addition to preserving many of the inherent restraints within the hip joint,2 it allows C-arm fluoroscopy image intensifie...
متن کاملAcetabular Cup Revision
The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an importa...
