The presence of QLP fractures greatly increase the surgical difficulty of acetabular fractures. This study aims to evaluate the clinical radiological outcomes of open reduction and internal fixation (ORIF) in QLP fractures in elderly patients and to investigate factors potentially affecting the result.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We conducted a retrospective study. A series of 37 consecutive patients with acetabular fracture involving the QLP aged 60 years and older who received ORIF between January 2010 and May 2019 were included. QLP fractures were classified according to Walid\u2019s classification system. Radiological outcomes were evaluated using Matta criteria and functional outcomes were assessed using the modified Merle d\u2019Aubign\u00e9 score. The relationships between Walid\u2019s classification and radiological or functional outcomes were analyzed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>According to Walid\u2019s classification, 18, 13, 6 were classified as QLP1, QLP2 and QLP3, respectively. The average follow-up was 35.5\u2009\u00b1\u200910.7 months. We obtained anatomic reduction in 48.6\u2009% (18\/37) of cases, imperfect reduction in 40.5\u2009% (15\/37) of cases, and poor reduction in 10.8\u2009% (4\/37) of cases. Excellent-good functional scores were found in 83.7\u2009% (modified Merle d\u2019Aubign\u00e9). There were no cases of screw entering the hip, pull-out and loosening or implant failure during the follow-up. Walid\u2019s classification was positively correlated with radiological outcomes of reduction (<jats:italic>r<\/jats:italic>\u2009=\u20090.661; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), and functional outcomes (<jats:italic>r<\/jats:italic>\u2009=\u20090.478; <jats:italic>P<\/jats:italic>\u2009=\u20090.003).
