Use of Intraoperative X-rays to Optimize Component Position and Leg Length During Total Hip Arthroplasty

Comparisons of Preoperative Three-Dimensional Planning and Surgical Reconstruction in Primary Cementless Total Hip Arthroplasty

“…In the present study, planned leg-length was reproduced with an accuracy of 0.3 mm ± 2.3, which is comparable to other series using preoperative 3D templating [15,17]. Only one patient (+6 mm) has to be considered an outlier as defined by Ezzet and McCauley [19], who proposed a threshold of 5 mm. However, no patient in our series has been complaining about a symptomatic leg lengths discrepancy.…”

“…However, no patient in our series has been complaining about a symptomatic leg lengths discrepancy. Of note, authors using 2D templating [13] based on plain x-rays and cemented stems or intra-operative x-rays [19] achieved comparable accuracies.…”

Early complications of primary total hip arthroplasty in the supine position with a modified Watson-Jones anterolateral approach

“…As Ezzet et al reported a single intraoperative anteroposterior pelvis radiograph to be a reliable, quick, and inexpensive means of determining acetabular positioning. 12 We did not have intraoperative navigation system, however, we should have to use intraoperative radiographic imaging for to optimize component position. According to our experience, we highly recommend for using of an intraoperative navigation system or intraoperative radiographic imaging during this technically demanding procedure.…”

An Alternative Intraoperative Radiographic Method for Optimizing Cup Inclination during Total Hip Arthroplasty

“…In addition, although a surgical navigation system provides greater accuracy and advanced navigation techniques, such systems cannot be used extensively because they are relatively expensive and prolong the duration of surgery. In contrast, intraoperative fluoroscopy is simple and less time‐consuming and is widely used in clinical practice. Ezzet and McCauley found that intraoperative anteroposterior (AP) pelvic radiography is very useful for managing THAs.…”

“…In contrast, intraoperative fluoroscopy is simple and less time‐consuming and is widely used in clinical practice. Ezzet and McCauley found that intraoperative anteroposterior (AP) pelvic radiography is very useful for managing THAs. In a series of over 200 consecutive primary THAs, they found single intraoperative AP pelvis radiography to be a reliable, quick, and inexpensive means of determining acetabular abduction, acetabular medialization, leg length and femoral alignment.…”
