Background Surgical treatment of acetabular fractures involving quadrilateral plate is a challenge to orthopaedic surgeons. We have developed a novel fixation technique using a special shaped reconstruction plate combined with several buttress screws of quadrilateral plate which was also called Dynamic Anterior Plate-Screw System for Quadrilateral plate (DAPSQ) to treat acetabular fractures involving quadrilateral plate since 2005(RP group). And the long-term follow-up results have confirmed the effectiveness and safety of this technique. After 2016, anatomical titanium plate (ATP group) of DAPSQ have been designed and applied. The aim of the study was to compare the clinical efficacy of anatomical plate and the reconstruction plate of DAPSQ in the treatment of quadrilateral plate fractures. Methods We led a propensity-matched cohort study of quadrilateral plate fractures. Twenty-two patients were included in the ATP group during the inclusion period (2016-2018), and were matched to 22 cases in our database of RP group (2008-2016). The primary outcome measures were quality of reduction and functional outcomes. Intraoperative conditions were also compared. Results Of these 22 consecutive patients in ATP group, the mean age was 46.7 years and the most common fracture pattern was a both-column fracture (12cases, 54.5%) according to Letournel-Judet classification. The mean follow-up period was 23.1 months (range 12-37). There were no significant differences between the two groups with regards the quality of reduction using the Matta radiological criteria and functional outcomes evaluated by the modified Merle d’Aubigné score( P > 0.05). Compared with the RP group, the ATP group has a shorter operation time(245.1 minutes vs. 286.8 minutes, P = 0.020), less intraoperative blood loss (1136.4 mL vs. 1777.3mL, P = 0.014) and transfusion (780.9 vs. 1256.8mL, P = 0.035). The complication rate was 18.2% in ATP group, and there was no significantly difference compared with the RP group (36.4%)( P > 0.05). None of the cases in the two groups had quadrilateral screws entering the hip or implant failure. Conclusion s The fixation of anatomical titanium plate in quadrilateral plate fractures showed a similar result to the reconstruction plate, in terms of quality of reduction and functional outcome. The anatomical titanium plate of DAPSQ has the advantages of short operation time, less intraoperative bleeding and blood transfusion, and it is worth further promotion and research.

“…Synthes has introduced precontoured quadrilateral surface plate reinforced with pelvic brim plate with a slot for a lag screw for fixation of quadrilateral plate fractures. In a biomechanical study by Zha et al, 5 multidirectional titanium infrapectineal plates provides strongest fixation for such fractures, however it requires a steep learning curve and also is associated with increased bleeding rates due to injury to corona mortis while using Stoppa approach.…”

Musculoskeletal injuries such as dislocation of the shoulder and hip joints and fractures of the femoral neck are known complications of seizures. Bilateral central subluxation of the hip joint with associated bilateral quadrilateral plate fracture is a rare entity and is prone to delayed diagnosis, even more so in patients who experience post-seizure disorientation. The authors report the case of a 74-year-old male patient with bilateral central subluxation of the hip joint with associated bilateral quadrilateral plate fracture due to seizure activity. Bilateral open reconstruction and fixation of the quadrilateral plate with a 3.5-mm pre-bent reconstruction plate reinforced with 3.5-mm pelvic brim reconstruction plate was performed. In conclusion, this case is an example of rare bilateral quadrilateral plate fracture caused due to seizure activity, a fracture for which a high level of suspicion should be kept in mind while evaluating the patient post-seizure episode.

Background Because of the peculiar anatomy and complex geometry of this region, surgical treatment of acetabular fractures involving quadrilateral plate is a challenge to orthopaedic surgeons. Many scholars consider that quadrilateral plate exist a absolute “dangerous zone” for screw placement and have designed a variety of buttress plates to control medial displacement of the quadrilateral surface. In order to achieve the safe and effective fixation in quadrilateral plate, we have developed a novel fixation technique using a special shaped reconstruction plate combined with several buttress screws of quadrilateral plate which was called Dynamic Anterior Plate-Screw System for Quadrilateral plate (DAPSQ) since 2005(RP group). And the long-term follow-up results have confirmed the effectiveness and safety of this technique. After 2016, a set of anatomical titanium plate(ATP group) of DAPSQ have been designed and applied for the treatment of quadrilateral plate fractures. The aim of this study was to compare the efficacy of anatomical titanium plate versus the reconstruction plate in the treatment of quadrilateral plate fractures. Methods We led a propensity-matched cohort study of quadrilateral plate fractures, and twenty-two patients were treated with anatomical titanium plate of DAPSQ in the inclusion period(2016-2018), and were matched to 22 cases in our database of RP group(2008-2016). The primary outcome measures were quality of reduction and functional outcome. Intraoperative conditions included surgical time, bleeding, and blood transfusion and the postoperative complications were also compared. Results Of these 22 consecutive patients in ATP group, the mean age was 46.7 years and the most common fracture pattern was a both-column fracture(12cases, 54.5%) according to Letournel-Judet classification. The mean follow up period was 23.1 months (range 12-37). There was no significant differences between the two groups with regards the quality of reduction using the Matta radiological criteria and functional outcomes evaluated by the modified Merle d’Aubigné score(P>0.05). Compared with the RP group, the ATP group has a short operation time(245.1 minutes vs. 286.8 minutes, P = 0.020), less intraoperative blood loss(1136.4 mL vs. 1777.3mL, P = 0.014) and transfusion(780.9 vs. 1256.8mL, P = 0.035). The complication rate was 22.7% in ATP group, and there was no significantly difference compared with the RP group(54.5%)(P>0.05). None of the cases in the two groups had quadrilateral screws entering the hip or implant failure. Conclusions The fixation of anatomical titanium plate in quadrilateral plate fractures showed similar result to the reconstruction plate, in terms of quality of reduction and functional outcome. But the utility of anatomical titanium plate had the advantages of shorter operation time, less bleeding and transfusion which is worthy to recommend.
