Pelvic lift does not differ in anterolateral, transgluteal approaches during THA

Issue: September 2017

Intraoperative pelvic lift did not differ between patients who underwent an anterolateral or transgluteal approach at the time of cup implantation during total hip arthroplasty, according to a recently published study.

Researchers matched 30 patients undergoing total hip arthroplasty (THA) through a minimally invasive anterolateral approach with a historical age- and sex-matched control group undergoing THA through a transgluteal approach. They measured iatrogenic lifting of the pelvis with a smartphone using a 3-axis accelerometer and determined the inclination and anteversion of the cup postoperatively on pelvic radiographs.

Results showed patients in the transgluteal group had a markedly stronger pelvic lift after the completion of cup implantation vs. the anterolateral group. Researchers found the anterolateral group had higher cup position inclination, but reduced anteversion in the postoperative radiographic evaluation. Patients who underwent the transgluteal approach experienced a longer duration of surgery at 62.7 minutes vs. 48.2 minutes in the anterolateral group. – by Casey Tingle
