Limited Range Of Motion

After a total hip arthroplasty, a limited range of motion and lower-limb disability continue to be observed, with these being mainly associated with the implant design and the head-to-neck ratio. Larger diameters of the head bearings were assumed to provide better stability, a larger range of motion, and smaller risks of dislocation and stem-to-liner impingement. However, these claims have never been demonstrated in real patients. The specific aim of this study was to assess, via multi-instrumental analysis, whether the range of motion of a replaced hip is limited by the stem-to-liner contact in patients with large femoral head diameters. Twenty-three patients with a total hip arthroplasty were evaluated at their one-year follow-ups using clinical and instrumental examinations. A combined three-dimensional gait analysis of the full body and videofluoroscopy analysis of the replaced hip were performed during the execution of standard, i.e., daily living, and more demanding motor tasks. The latter were meant to reach the extreme range of motion at the replaced hip site, thus revealing possible stem-to-liner contact. An original technique based on imaging and computer-aided design (CAD) models of the prosthesis components was developed to calculate the stem-to-liner distance. Excellent clinical scores were observed in the study. The gait analysis showed that the range of motion of the replaced hip in the sagittal plane, averaged over all patients, ranged from 28° to 78° in standard activities. In more demanding tasks, single peaks were as high as 110°, 39°, and 60° in the sagittal, frontal, and transverse anatomical planes, respectively. In all motor tasks, the stem-to-liner distances ranged from 8.7 to 13.0 mm on average, with one outlier minimum distance being 2.2 mm. This study shows that, even in demanding motor tasks and with an extreme range of motion, the hip joint replaced with large femoral head diameters did not experience impingement between the prosthesis components.

Abstract Background Obtaining a larger theoretical range of motion (ROM) is crucial to avoid prosthetic impingement after total hip arthroplasty (THA); however, no reports have examined the permissible range values of combined anteversion (CA) satisfying targeted ROM without prosthetic impingement. This retrospective study aimed to evaluate the possible postoperative CA extent that would allow meeting target ROM criteria according to Yoshimine’s theory using computed tomography (CT)-based three-dimensional motion analysis after THA. Methods This study included 114 patients (133 hips) who underwent cementless primary THA using a CT-based navigation system and implants (oscillation angle ≥ 135°). Implant positions were determined using Yoshimine's CA formula. Postoperative evaluation was conducted using a three-dimensional templating software for CT data. The postoperative Yoshimine’s and Widmer’s CA was calculated, and the difference between the target and postoperative values was defined as the error of Yoshimine’s CA and Widmer’s CA. Prosthetic ROM was assessed by Yoshimine’s stringent criteria for activities of daily living. Based on fulfilling these criteria, all patients were divided into the ROM (+) and ROM (-) groups. Evaluation items were compared between the two groups. Results There were 111 and 22 hips in the ROM (+) and ROM (-) groups, respectively. A significant difference was noted in the absolute error of Yoshimine’s and Widmer’s CA between the two groups. Using receiver operating characteristic analysis, threshold values of 6.0 (higher values indicate greater disability; sensitivity 90.9%, specificity 72.1%) for the absolute Yoshimine’s CA difference (area under the curve [AUC] 0.87, P < 0.01) and 6.9 (higher values indicate greater disability; sensitivity 68.2%, specificity 88.3%) for the absolute Widmer’s CA difference (AUC 0.83, P < 0.01) were predictors in the ROM (-) group. Conclusions The target range of Yoshimine’s CA (90.8°±6.0°) and Widmer’s CA values (37.3°±6.9°) was crucial in implant orientation for obtaining theoretical ROM without prosthetic impingement after THA.

Hip simulators are regularly used by researchers to assess total hip arthroplasty (THA) implants, range of motion, stability, and alignment of acetabular cup and stem. Previous papers have described three types of simulators: three-dimensional protractors, biaxial rocking motion (BRM) protractors, and single-axis prosthetic range-of-motion (PROM) devices. We have developed a new hip simulator in which the ROM device is completely automated in three independent axes (elevation, internal/external rotation, and plane of elevation). Coupled with the simulator, we used a FaroArm Gold Series coordinate measuring machine (CMM) to accurately align the implant components. The results show that the methodology and alignment setup are accurate and repeatable. With this simulator and digitizer, we are able to study the characteristics of numerous THA implants at various orientations of the pelvis, acetabular cup, stem, and femur.
