Surgical outcomes of patients with acetabular fractures and quadrilateral plate involvement

Background Open reduction and internal fixation (ORIF) remain the standard method of treating acetabular fractures. Many authors report poor results in quadrilateral plate fractures of the acetabulum with the use of ORIF. The objective was to evaluate outcomes of quadrilateral plate fractures of the acetabulum. Material and methods Surgical outcomes of 55 patients with quadrilateral plate fractures of the acetabulum were retrospectively reviewed between 2009 and 2019. Early postoperative results were followed up in 55 patients. Surgical treatment was provided for 32 (58.2 %) control patients with acetabular fractures and 23 patients (41.8 %) with quadrilateral plate fractures of the acetabulum in the main group. Long-term results were explored in 45 patients aged 18 to 60 years with acetabular fractures (control group, n = 24) and in combination with quadrilateral plate involvement (main group, n = 21). Results Surgical interventions were performed by one team consisting of the same specialists. Surgical outcomes in oth clinical groups were evaluated according to 11 criteria. Discussion The results of surgical treatment of acetabular fractures and quadrilateral plate involvement were associated with the negative impact of quadrilateral plate involvement on the duration and volume of blood loss, intraoperative and late complications and dynamics in the development of post-traumatic hip arthrosis. The results obtained were comparable with the data of the itation sources. Conclusion A comparative analysis of the outcomes suggested a negative impact of quadrilateral plate involvement on the results of surgical treatment and an objective necessity to rank quadrilateral plate fractures of the acetabulum as a risk factor for adverse outcomes with ORIF.
