The aim of this study was to compare the recently developed direct anterior approach (DAA) and the classic posterior approach (PA) regarding the characteristics of nerve injuries in Crowe IV DDH patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A total of 149 Crowe IV DDH patients who underwent THA were retrospectively included and divided into 2 groups based on surgical approach (DAA: 68 patients and PA: 81 patients). Postoperatively, the nerve injury was evaluated both clinically and electrophysiologically. The incidence, severity and prognosis of nerve injuries and involved nerves were compared and analysed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The overall incidence of nerve injury was 30.88% (21\/68) for the DAA and 29.63% (24\/81) for the PA (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.868).

However, there is an increased incidence of femoral nerve injury when compared to the posterior approach.
