Radiographic measurement of leg-length change in the nonoperative leg during total hip arthroplasty: a potential indicator of imaging error?
25% of patients were found to have leg length changes ≥2 mm on the non-operative limb demonstrating potential error in using radiographic measurements as the standard comparator for assitive technologies in THA.
Evaluating Alternate Registration Planes for Imageless, Computer-Assisted Navigation During Total Hip Arthroplasty
Using Intellijoint HIP to examine various patient registration methods found the hip-shoulder axis to be the most accurate and consistent for acetabular component position.
A Novel Method for Correcting Pelvic Tilt on Anteroposterior Pelvic Radiographs.
Use of the pubic symphysis and transichial line provide a reliable method for correcting pelvic tilt on AP radiographs.
Pelvic pitch and roll during total hip arthroplasty performed through a posterolateral approach. A potential source of error in free-hand cup positioning.
During THA, patient pelvic roll can lead to underestimation of cup anteversion. Intellijoint HIP can account for pelvic movements and account for errors arising from patient pelvic movements.
Evaluation of tilt-correction of anteversion on AP pelvic radiographs in THA.
A pelvic tilt correction method tested is not a viable option to correct for pelvic tilt in THA imaging.
Undetected intraoperative pelvic movement can lead to inaccurate acetabular cup component placement during total hip arthroplasty: A mathematical simulation estimating change in cup position
Intraoperative pelvic movement can result in inaccurate THA component placement. Intellijoint HIP is able to account for these inaccuracies during THA.
