“…When using the NALP, the compression screws were driven into the anterior and posterior columns through the plate to compress the acetabular fracture ends. However, although the auxiliary insertion point was provided when the NALP was used, the correct implantation was also dependent on the combined application of the guide module and the perspective, which increased the operation time [21,22].…”

BackgroundA novel anatomical locking plate (NALP) was designed. The NALP is fixed via an anterior column screw and a Magic screw to apply pressure on the acetabular fracture ends. This study was performed to compare the reduction effect and clinical outcome of the NALP versus the anatomical locking plate (ALP) for acetabular fractures involving both columns.MethodsFrom January 2013 to January 2018, 22 patients with acetabular fractures involving both columns were treated using the NALP or ALP in a single institution. The general condition and type of fracture were recorded. The NALP and ALP groups were compared regarding the Letournel fracture classification, operative approach, time from injury to operation, intraoperative bleeding volume, and operation time. The radiographic reduction outcome and hip function at final follow-up were compared between the two groups based on the Matta scores and Harris hip scores, respectively.ResultsThe NALP was used in 10 patients, while the ALP was used in 12. Three patients had transverse fractures, 12 had transverse fractures involving posterior wall, and 7 had double-column fractures. The two groups had no significantly differ regarding sex, age, affected side, Letournel fracture classification, operative approach, or follow-up duration. The time from injury to the operation was 20.70±1.2 days in the NALP group and 13.17±7.5 days in the ALP group (p=0.089). The operation time was 332.20±128.9 minutes in the NALP group and 257.50±91.6 minutes in the ALP group (p=0.128). The intraoperative blood loss volume was 1550.00±869.5 ml in the NALP group and 666.67±370.1 ml in the ALP group (p=0.011). The Matta score at final follow-up was 1.10±0.8 in the NALP group and 2.46±1.9 in the ALP group (p=0.045). The Harris hip score at final follow-up was 87.50±10.5 in the NALP group and 81.00±10.1 in the ALP group (p=0.0782).ConclusionThe NALP achieves adequate compression of the acetabular fracture ends and obtains stronger fixation than the ALP.Trial registrationChiCTR,ChiCTR2000030825.

Objective The objective of the present paper was to investigate the value of obturator oblique and pubic ramus inlet views in guiding anterior column acetabular screw insertion. Methods We collected pelvic CT scans at the diagnostic imaging center of our hospital between 2017 and 2019. Virtual three‐dimensional (3D) models of the pelvis were created based on the CT scans. Then the transparency was adjusted to 30%. Two identical copies of the 3D model data were made. 3D model replications were divided into a control group and an experimental group. In the control group, the screw was inserted into the anterior acetabular column using obturator‐outlet and iliac‐inlet views. In the experimental group, the screw was guided under obturator oblique and pubic ramus inlet views. Based on whether the screw penetrated the hip joint and/or exited the pubic ramus, models were divided into three grades. Grade I: the screw travels completely within the anterior column bone corridor; Grade II: the screw exits the superior pubic ramus, but the length of the screw outside the channel does not exceed 1/2 of the anterior column; Grade III: the screw exits the superior pubic ramus and the length of the screw outside the corridor exceeds 1/2 of the anterior column. We compared the screw placement quality of the two groups and analyzed differences between genders. In addition, the distance between the screws and the acetabulum was recorded and compared among the two groups. Results A total of 110 hemipelves were selected, including those of 80 men and 30 women, with an average age of 46.76 ± 14.26 years. In the control group, the screw quality of 64 models (58.2%) was Grade I. In the experimental group, 94 models (85.5%) had Grade I screw placement quality. Grade II screw placement quality accounted for 18.2% of the control group and 7.3% of the experimental group. In the control and the experimental groups, there were 26 and 8 cases with Grade III screw placement quality, respectively. The quality of screw placement in the experimental group was significantly better than that in control group, and the difference between the two groups was statistically significant (P < 0.01). The distance between the screw and the acetabulum in the control group and experimental group was 0.92 ± 0.49 mm and 2.78 ± 1.15 mm, respectively. The difference between the two groups was statistically significant. Conclusion Anterior column acetabular screws can be inserted successfully and more accurately using the obturator oblique and pubic ramus inlet views.
