Component placement accuracy of two digital intraoperative fluoroscopy supplementation systems in direct anterior total hip arthroplasty

Introduction Intraoperative fluoroscopy (IF) may increase accuracy of component placement when performing direct anterior approach total hip arthroplasty (THA), however, unguided IF continues to produce inconsistent results. Supplementation of IF, with a digital grid (Grid) system or digital overlay...

The purpose of this study was to compare component placement accuracy following THA when IF was supplemented with the Grid or Overlay technique. Materials and methods Acetabular abduction and anteversion, with leg length discrepancy (LLD) and global hip offset (GHO) were retrospectively evaluated for unilateral and bilateral THA patients from 6-week post-operative radiographs. Target component placement were GHO and LLD &lt; 10 mm, abduction 45° ± 10° and anteversion 15° ± 10° for Overlay and 17° ± 10° for Grid. Differences between the Overlay and Grid were determined by univariate analyses. Results The Overlay and Grid groups included 178 patients (217 hips) and 262 patients (317 hips), respectively. Target placement with the Overlay and Grid was achieved for GHO in 98.3% and 95.7% of cases ( p  = 0.108), LLD in 100% and 98.4% of cases ( p  = 0.121), cup abduction in 98.2% and 97.4% of cases ( p  = 0.384), and cup anteversion in 97.7% and 71.1% of cases ( p  &lt; 0.001), respectively. Surgical time was significantly longer in Overlay compared to Grid (Unilateral 77.5 ± 14.1 min and 68.8 ± 12.2; p  &lt; 0.001; Bilateral 184.6 ± 27.0 min and 165.5 ± 23.1; p  &lt; 0.001, respectively). Conclusion Although no difference was found between the Grid and the Overlay cohorts for LLD, GHO or abduction angle, the Overlay resulted in greater accuracy for acetabular component anteversion angle, with only a slight decrease in surgical efficiency.</description><identifier>ISSN: 1434-3916</identifier><identifier>ISSN: 0936-8051</identifier><identifier>EISSN: 1434-3916</identifier><identifier>DOI: 10.1007/s00402-021-04008-6</identifier><identifier>PMID: 34160674</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Accuracy ; Arthritis ; Fractures ; Hip Arthroplasty ; Joint replacement surgery ; Medicine ; Medicine &amp; Public Health ; Orthopedics ; Osteoarthritis ; Patients ; Pelvis ; Trauma</subject><ispartof>Archives of orthopaedic and trauma surgery, 2022-06, Vol.142 (6), p.1283-1288</ispartof><rights>The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021</rights><rights>2021.
