Is transverse screw fixation really necessary in PAO?-A comparative study.

The optimal fixation technique in periacetabular osteotomy (PAO) remains controversial. This study aims to assess the stability of fixation in PAO with and without the use of a transverse screw. We performed a retrospective study to analyse consecutive patients who underwent PAO between January 2015 and June 2017.

Fixation stability and implant-associated complications in periacetabular osteotomy: a comparison of screw and K-wire fixation.

Aims: The aim of this study was to compare the fixation stability and complications in patients undergoing periacetabular osteotomy (PAO) with either K-wire or screw fixation.

Patients And Methods: We performed a retrospective study to analyze a consecutive series of patients who underwent PAO with either screw or K-wire fixation. Patients who were treated for acetabular retroversion or had previous surgery on the ipsilateral hip joint were excluded.
