“…From a previous portable navigation study [ 7 ], difference (mean ± standard deviation) in navigation and conventional groups for cup inclination was 2.8° ± 2.4°. Based on this finding, a sample size of 12 hips in each group was considered necessary to detect a significant difference between groups (ɑ = 0.05, power = 0.8).…”

Background This study aimed to determine the accuracy of acetabular cup insertion using a novel accelerometer-based navigation system in total hip arthroplasty (THA). Methods A single-surgeon study was conducted in which 62 prospective patients with navigation and 42 retrospective patients without navigation in a supine position were compared. Absolute values for errors of radiographic inclination and anteversion were calculated. Navigation error was also calculated. Factors that affected absolute value of navigation error in cup alignment were determined. Results In the navigation group, mean absolute errors for radiographic inclination and anteversion were 4.1° and 4.3°, respectively. In the control group, mean absolute errors were 6.6° in inclination (p < 0.01) and 5.9° in anteversion (p = 0.04). Mean absolute values of navigation error were 2.8° in inclination and 2.8°in anteversion. Factors affecting navigation errors were not found. Conclusion This novel accelerometer-based navigation system significantly increased the accuracy of cup placement during THA in the supine position.

“…As such, of 40 studies, 5 (12%) studies included patients, and 2 (5%) described cadaveric results. Among the clinical studies, there were 2% (1/40) of case series with an average score of 85 out of 100 points (85%) and 16 (16%) case series with an average score of 89 (SD 10.11) out of 100 points (89%) according to the Joanna Briggs Institute Critical Appraisal Checklist (refer to Multimedia Appendix 3 [ 17 - 19 , 21 , 25 , 26 , 28 , 30 , 31 , 33 , 34 , 36 , 38 , 39 , 41 , 45 , 49 ] for the full list). The 2 cadaveric studies also scored high based on Quality Appraisal for Cadaveric Studies scale, with average scores of 85 out of 100 points (85%) and 92 out of 100 points (92%) (refer to Multimedia Appendix 4 for the full list [ 44 , 50 ]).…”

“…This portable system combines the accuracy of image-free computer-based navigation systems with the convenience of traditional alignment techniques. Takada et al [ 19 ] prospectively assessed acetabular cup positioning using the portable image-free navigation system HipAlign and a manual goniometer during a procedure that was performed through a supine anterolateral approach; see Takada et al [ 19 ] for an image of a navigation sensor for a cup impactor. The absolute error of the difference between the CT-measured acetabular cup angle and HipAlign-measured acetabular cup angle was estimated.…”

Background Virtual and augmented reality (VAR) represents a combination of current state-of-the-art computer and imaging technologies and has the potential to be a revolutionary technology in many surgical fields. An increasing number of investigators have developed and applied VAR in hip-related surgery with the aim of using this technology to reduce hip surgery–related complications, improve surgical success rates, and reduce surgical risks. These technologies are beginning to be widely used in hip-related preoperative operation simulation and training, intraoperative navigation tools in the operating room, and postoperative rehabilitation. Objective With the aim of reviewing the current status of virtual reality (VR) and augmented reality (AR) in hip-related surgery and summarizing its benefits, we discussed and briefly described the applicability, advantages, limitations, and future perspectives of VR and AR techniques in hip-related surgery, such as preoperative operation simulation and training; explored the possible future applications of AR in the operating room; and discussed the bright prospects of VR and AR technologies in postoperative rehabilitation after hip surgery. Methods We searched the PubMed and Web of Science databases using the following key search terms: (“virtual reality” OR “augmented reality”) AND (“pelvis” OR “hip”). The literature on basic and clinical research related to the aforementioned key search terms, that is, studies evaluating the key factors, challenges, or problems of using of VAR technology in hip-related surgery, was collected. Results A total of 40 studies and reports were included and classified into the following categories: total hip arthroplasty, hip resurfacing, femoral neck fracture, pelvic fracture, acetabular fracture, tumor, arthroscopy, and postoperative rehabilitation. Quality assessment could be performed in 30 studies. Among the clinical studies, there were 16 case series with an average score of 89 out of 100 points (89%) and 1 case report that scored 81 (SD 10.11) out of 100 points (81%) according to the Joanna Briggs Institute Critical Appraisal Checklist. Two cadaveric studies scored 85 of 100 points (85%) and 92 of 100 points (92%) according to the Quality Appraisal for Cadaveric Studies scale. Conclusions VR and AR technologies hold great promise for hip-related surgeries, especially for preoperative operation simulation and training, feasibility applications in the operating room, and postoperative rehabilitation, and have the potential to assist orthopedic surgeons in operating more accurately and safely. More comparative studies are necessary, including studies focusing on clinical outcomes and cost-effectiveness.

“…In recent years, simpler portable navigation systems have been developed, and their accuracy has been reported. The accuracy of cup placement by various portable navigation systems in the supine position is 2.6°-3.7° for RI and 2.8°-3.8° for RA [10][11][12]. Okamoto et al reported that in DAA-THA, the cup placement rate within ± 5° was 56.6% in the alignment guide group and 72.2% in the portable navigation (Hip Align ® ) group [13].…”

Background In our institution, total hip arthroplasty (THA) is performed using the anterolateral supine (ALS) approach with intraoperative fluoroscopy. This study aimed to investigate and review the accuracy of acetabular cup placement in ALS-THA using intraoperative fluoroscopy. Methods A total of 142 patients with 154 joints (mean age 64.3 years, 30 males and 112 females) underwent ALS-THA with intraoperative fluoroscopy at the same institution. The target angle of the cup position was set at 40° for radiographic inclination (RI) and 5°–25° for radiographic anteversion (RA) based on the functional pelvic plane according to the pelvic motion during individual postural changes. The cup position angle was measured using postoperative computed tomography, and the error in the target angle was investigated. Results The target angle of RI was 40°, and the postoperative RI was 39.3° ± 4.3°. The target angle of the RA was 17° ± 2.6°, and the postoperative RA was 20.6° ± 3.7°. The absolute values of the error from the target angle were 3.6° ± 2.5° for RI and 4.2° ± 3.3° for RA. For RI and RA, 67.5% (104/154 joints) were within ± 5° of the target and 96.1% (148/154 joints) were within ± 10°. Conclusions The accuracy of cup positioning in ALS-THA using intraoperative fluoroscopy was good and appeared comparable to that of various navigation systems.
