The H\u2010shaped anatomical titanium plate (<jats:styled-content style=\"fixed-case\">HTP<\/jats:styled-content>) facilitates anatomical reduction, minimizes complications, and enhances safety, efficacy, and speed. This study aims to conduct biomechanical testing and clinical evaluation of <jats:styled-content style=\"fixed-case\">HTP<\/jats:styled-content> to assess its stability and efficacy in treating these fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In the biomechanical research, posterior column with posterior wall fractures was created on nine acetabular models procured from Sawbones, <jats:styled-content style=\"fixed-case\">USA<\/jats:styled-content> and were allocated to three fixation groups: (1) a single reconstruction plate combined with a single cortical screw (<jats:styled-content style=\"fixed-case\">PCS<\/jats:styled-content>), (2) double parallel reconstruction plates (<jats:styled-content style=\"fixed-case\">2P<\/jats:styled-content>), (3) <jats:styled-content style=\"fixed-case\">HTP<\/jats:styled-content>. Following anatomic reduction, cyclic loading and destructive experiments were conducted to assess the efficacy of different fixation devices under various loads for the posterior wall and column, as well as their peak load and structural stiffness. Additionally, we retrospectively analyzed the clinical data of 53 patients (46 males, 7 females; mean follow\u2010up 24.6\u2009\u00b1\u20093.2\u2009months) with the <jats:styled-content style=\"fixed-case\">HTP<\/jats:styled-content> at our hospital from April 2017 to January 2023.

Clinically, Postoperative Visual Analogue Scale scores significantly decreased, indicating effective pain management. 84.91% achieved anatomic reduction, with 92.45% and 90.56% good\/excellent functional outcomes (Merle d'Aubign\u00e9 Postel and Harris scores, respectively).
