“…The method of fracture reduction was performed as we described in detail previously 4 . It should be noted that the reduction of double-column fractures follows certain principles: fracture fragments should be reduced successively from the proximal side to the distal side, and from the periphery to the center.…”

“…The plate shaping process comprised three major steps: measuring the total anatomical length of the DAPSQ trajectory on the pelvis, choosing an appropriate length of C-shape reconstruction plate, and making both ends of the plate upturned and reverse twisted. The specific screw placement sequence was performed using the method described previously 4 , which was crucial to the success of fixation (Fig. 5).…”

“…The fractures of the quadrilateral plate were reduced and pre-prepared 3D printed DAPSQ was placed in the proper position. (C) Following the specific screw placement sequence described previously 4 , the plate was pressed onto the bone surface using special instruments and the first screw was fixed on the pubis (also called the pubis screw). (D-E) Drilling holes along the surface of the quadrilateral plate; the first quadrilateral screw was placed parallel to the surface of quadrilateral plate.…”

“…Our research group has been developing a novel method called the dynamic anterior plate-screw system for the quadrilateral area (DAPSQ) to fix acetabular fractures since 2005 and has obtained satisfactory clinical results 4 . DAPSQ consists of two major components: a special shaped reconstruction plate and several dynamic compression screws for quadrilateral plates (which we call quadrilateral screws).…”

“…However, the DAPSQ reconstruction plate needs to be shaped temporarily during the operation. Surgeons need to consider the length-dependent zonal division of the three parts: the iliac region, the quadrilateral region, and the pubic region 4 . The torsion angle at both ends of the DAPSQ plate is adjusted based on surgeons' experience.…”

Objective To compare the clinical efficacy and safety of a personalized three‐dimensional (3D) printed dynamic anterior plate–screw system for the quadrilateral area (DAPSQ) titanium plate and a traditional DAPSQ reconstruction plate in the treatment of double‐column acetabular fractures. Methods This was a retrospective case‐control study. From May 2014 to January 2018, 43 patients with double‐column acetabular fractures underwent open reduction and internal fixation. Among these, 20 cases were fixed with a 3D printed DAPSQ plate (3D printed group) and 23 cases were fixed with a DAPSQ reconstruction plate (control group). The 3D printed group comprised 15 men and 5 women, with an average age of 50.1 ± 8.2 years. The control group comprised 16 men and 7 women, with an average age of 51.0 ± 8.6 years. The evaluation index included the surgical data (i.e. blood loss, operating time, duration of hospital stay, and intraoperative and postoperative complications), position and length of implants, reduction quality, hip function, and related complications. The reduction quality was evaluated using the Matta scoring standard and hip function was evaluated using the modified Merle d’Aubigné score. Results A total of 43 patients met the inclusion criteria. The mean postoperative follow up was 35.2 months in the 3D printed group and 36.9 months in the control group. There were no significant group differences in demographic data between the two groups. The position and length of the 3D printed implants were generally in accord with preoperative planning using a 3D pelvic model. Patients in the 3D printed group had significantly shorter operation time (223.2 vs 260.5 min, P < 0.05) and less intraoperative blood loss (930.4 vs 1426.1 mL, P < 0.05) compared to the control group. Anatomic, imperfect, and poor reduction was obtained in 13, 5, and 2 cases in the 3D printed group, respectively, and was obtained in 12, 8, and 3 cases in the control group. The modified Merle d’Aubigné scores were excellent in 11 cases, good in seven cases, and fair in two cases in the 3D printed group. They were excellent in 11 cases, good in eight cases, fair in three cases, and poor in one case in the control group. The reduction quality and hip function did not differ within the groups (P > 0.05). The general complication rate in the 3D printed group and the control group was 15% and 26.1%, respectively, but the difference between the two groups was not statistically significant. Conclusion Use of a personalized 3D printed DAPSQ plate has potential advantages in reducing the operation time and blood loss during the treatment of double‐column acetabular fractures.

Objectives In geriatric acetabular fractures, the quadrilateral surface (QLS) was frequently involved in acetabular fracture patterns and accompanied by medial displacement. It was important to buttress the medial displaced QLS and reconstruct the congruity of the affected acetabulum. To evaluate the clinical effectiveness of the novel infra‐pectineal quadrilateral surface buttress plates for the treatment of geriatric acetabular fractures. Methods Twenty‐three geriatric patients who were treated for acetabular fractures involving QLS with the novel infra‐pectineal buttress plates (NIBP) through a single supra‐ilioinguinal approach between January 2015 and June 2019 were retrospectively analyzed; all patients received at least 1 year's follow‐up. All patients were aged ≥60 years old and including 18 males and five females. Radiologic and clinical outcomes of patients involved in the study were collated and analyzed according to the Matta scoring system and the Merle D'Aubigné–Postel scoring system. The functional recovery scoring was compared using q‐test. Results All 23 consecutive patients had relatively satisfactory clinical treatment effectiveness. Average ages, length of incision, operation time, and intraoperative blood loss were 69.8 ± 6.1 years, 12.1 ± 2.6 cm, 166.5 ± 43.5 min, and 500 (500,700) ml, respectively. According to the Matta scoring system, 14 cases of reduction were graded as excellent, five as good, and four as fair. At the last follow‐up, the clinical outcome evaluation was excellent in 13 cases, good in seven cases, and poor in three cases with the use of the Merle D'Aubigné–Postel scoring system. The difference of modified Merle D'Aubigne‐Postel score at 3 months, 6 months and last follow up was statistically significant (F = 21.56, p < 0.05). Postoperative lateral femoral cutaneous nerve injury occurred in three patients and heterotopic ossification occurred in one patient. Conclusions For the treatment of geriatric acetabular fractures, the NIBP could provide stable and effective fixation to the QLS involved acetabular fractures, and related satisfactory clinical results with few complications were noted.
