Component placement in direct lateral vs minimally invasive anterior approach in total hip arthroplasty: Radiographic outcomes from a prospective randomized controlled trial
Journal of Arthroplasty Apr 14, 2019
Brun OCL, et al. - In this prospective, randomized controlled trial, authors determined the radiographic outcomes of component placement in direct lateral approach (DLA) in comparison with minimally invasive direct anterior approach (MIDA) in total hip arthroplasty (THA) among 164 patients of age 20-80 years. They observed the mean degrees of inclination and anteversion higher in the MIDA group (mean difference=2.5° and mean difference=3.6°, respectively) whereas the mean cement-mantle was significantly thicker in zone 1 in the MIDA group (mean difference=0.51 mm). No differences were reported in frontal or lateral femoral stem position, global offset restoration or leg length discrepancy. They overall suggested similar component placement in the 2 surgical procedures.
