“…The quality assessment process could only be performed in 18 (58%) out of 31 studies, where either human study populations or cadaveric subjects were evaluated. As such, 7 studies (39%) included patients [26][27][28][29][30][31][32], and 11 (61%) described cadaveric results [32][33][34][35][36][37][38][39][40][41][42].…”

Background: Computer-assisted solutions are changing surgical practice continuously. One of the most disruptive technologies among the computer-integrated surgical techniques is Augmented Reality (AR). While Augmented Reality is increasingly used in several medical specialties, its potential benefit in orthopedic surgery is not yet clear. The purpose of this article is to provide a systematic review of the current state of knowledge and the applicability of AR in orthopedic surgery. Methods: A systematic review of the current literature was performed to find the state of knowledge and applicability of AR in Orthopedic surgery. A systematic search of the following three databases was performed: "PubMed", "Cochrane Library" and "Web of Science". The systematic review followed the Preferred Reporting Items on Systematic Reviews and Meta-analysis (PRISMA) guidelines and it has been published and registered in the international prospective register of systematic reviews (PROSPERO). Results: 31 studies and reports are included and classified into the following categories: Instrument / Implant Placement, Osteotomies, Tumor Surgery, Trauma, and Surgical Training and Education. Quality assessment could be performed in 18 studies. Among the clinical studies, there were six case series with an average score of 90% and one case report, which scored 81% according to the Joanna Briggs Institute Critical Appraisal Checklist (JBI CAC). The 11 cadaveric studies scored 81% according to the QUACS scale (Quality Appraisal for Cadaveric Studies). Conclusion: This manuscript provides 1) a summary of the current state of knowledge and research of Augmented Reality in orthopedic surgery presented in the literature, and 2) a discussion by the authors presenting the key remarks required for seamless integration of Augmented Reality in the future surgical practice. Trial registration: PROSPERO registration number: CRD42019128569.

“…Another study by Ogawa H. et al [28] investigated cup placement in total hip arthroplasty measured by an AR approach. In 56 total hip arthroplasties, the orientation of the acetabular cup (anteversion and inclination) were measured either using an AR smartphone or a goniometer.…”

“…In other words, stem anteversion, like cup anteversion, is an important factor in reducing postoperative complications of THA. There have been some reports stating that it is possible to set the cup anteversion with high accuracy at low cost by using the accelerometer-based portable navigation and mechanical navigator as opposed to using computer-assisted navigation [7,[9][10][11][12][13]. However, with regard to stem anteversion, there is almost no method for accurately determining the anteversion angle of the stem during surgery apart from computer-assisted navigation.…”

“…In 1978, Lewinneck et al de ned the safe zone of the cup as an inclination of 40 ± 10 degrees and an anteversion of 15 ± 10 degrees; this remains the goal for some surgeons even today [1]. In clinical practice, tools, such as the computer-assisted navigation system [5,6], accelerometer-based portable navigation [7], robotic-assisted system [8], and mechanical navigator [9][10][11][12][13], have proven useful in achieving accurate placement of acetabular components. However, there are very few reports about the ideal stem anteversion angle (SAA) on the femoral side.…”

Background Background: Stem anteversion is important in reducing postoperative complications in total hip arthroplasty (THA). THA utilizing the combined-anteversion theory requires stem anteversion angle (SAA) measurement intraoperatively; however, intraoperative SAA estimation is difficult for surgeons without computer-assisted navigation system. We evaluated the accuracy of the SAA measured intraoperatively using a newly developed device by comparing the three-dimensional measurements using postoperative computed tomography (CT).Materials & Methods In 127 hips in 127 patients who underwent unilateral THA at our hospital, we used our newly developed device that can be easily attached to rasping broach handles for measuring the SAA intraoperatively, which required the addition of the correction angle obtained in the preoperative epicondylar view. Postoperative SAA and its discrepancies from the measured intraoperative SAA with or without adding the correction angle were compared between the groups to evaluate the usefulness of the device.Results The intraoperative SAA measured by the device was 17.93 ± 7.53°. The true SAA measured on postoperative CT was 26.40 ± 9.73°. The discrepancy between the intraoperative SAA and true SAA was 8.94 ± 5.44° (without the correction angle), and 4.93 ± 3.85° (with the correction angle). Accuracy with a discrepancy of <5 degrees was achieved in 77 (60.6%) and <10 degrees was achieved in 113 (89.0%). The accuracy was unaffected by the stem placement angle (varus/valgus, or flexion/extension), or ipsilateral knee osteoarthritis.Conclusion The SAA measuring device, easily attachable to various rasping handles, is useful to measure the intraoperative SAA in a simple, economical, and noninvasive manner during THA.Level of Evidence Therapeutic Level IV.

Purpose of the study — to improve the two-dimensional planning of total hip joint arthroplasty to ensure precise positioning of the acetabular component in the deformed acetabulum. Materials and methods. Features of roentgenological anatomy of acetabulum and its coverage were studied on 1058 hip joint x-rays in the AP view in accordance with the procedure developed by the authors to define acetabular square — the site of standard positioning of a spherical femoral head in the acetabulum or of a hemispherical acetabular component. The method consisted of identifying the apex of “teardrop” figure; the most lateral points of the pelvic terminal line and roof of the acetabulum; superior part of the acetabular cavity; medial and inferior points of acetabular coverage, and building the sides of acetabular square — medial, inferior, lateral and superior boundary lines. Connection of “teardrop” apex and lateral point of the pelvic terminal line formed the medial side of acetabular square, and a perpendicular to that line drawn through the “teardrop” apex to its inferior side. The lateral side was drawn either through the intersection of the ascending diagonal line — bisector from the top of the “teardrop” figure with the contour of the acetabulum roof, or was a part of the projection of the most lateral point of the acetabular roof on the inferior side of the square. The superior side was a perpendicular connecting the intersection of the ascending diagonal and lateral bounding lines with the medial side of the acetabular square. The area of the deformed acetabular cavity located outside of the acetabular square was assessed as the acetabular defect. Results. Method of defining the acetabular square allowed to identify types of ratios between acetabular cavity and acetabular coverage in transverse (9 types) and longitudinal (7 types) direction. Combination of transverse ratio of acetabular cavity and coverage with longitudinal type allowed to define the options of acetabular deformities in two-dimensional view. The authors identified 25 types of acetabular deformities. Bone defects of acetabular walls were of the major importance among all anatomical features. Cranial defect of acetabulum was observed in 450 cases, medial wall defect — in 38 cases, defect including cranial and medial areas — in 7 cases. Conclusion. The method suggested by the authors to determine acetabular square and acetabular deformity variations allows to screen the anatomical features of the acetabulum during two-dimensional preoperative planning and to make an informed decision on the need to use other planning techniques. The type of acetabular deformity identified during preoperative planning allows to elaborate the indications for replacement of acetabular bone defects and/or resection of acetabular osteophytes.
