Objective:
To investigate the risk of postoperative surgical site infections after plate fixation of the anterior pelvic ring subsequent to preperitoneal pelvic packing (PPP).
Design:
Retrospective observational cohort study.
Setting:
Level I academic trauma center.
Patients:
Adult trauma patients with unstable pelvic ring injuries requiring surgical fixation of the anterior pelvic ring.
Intervention:
Pelvic plate fixation was performed as a staged procedure after external fixation and PPP/depacking (PPP group; n = 25) or as a single-stage primary internal fixation (control group; n = 87).
Main Outcome Measure:
Incidence of postoperative surgical site infections of the pelvic space.
Results:
Anterior pelvic plate fixation was performed in 112 patients during a 5-year study period. The PPP group had higher injury severity scores and transfused packed red blood cells than the control group (injury severity score: 46 ± 12.2 vs. 29 ± 1.5; packed red blood cells: 13 ± 10 vs. 5 ± 2; P < 0.05). The mean time until pelvic depacking was 1.7 ± 0.6 days (range: 1-3 days) and 3.4 ± 3.7 days (range: 0-15 days) from depacking until pelvic fracture fixation. Two patients in the PPP group and 8 patients in the control group developed a postoperative infection requiring a surgical revision (8.0% vs. 9.2%; n.s.). Both PPP patients with a pelvic space infection had undergone anterior plate fixation for associated acetabular fractures.
Conclusions:
These data support the safety of the PPP protocol for bleeding pelvic ring injuries due to the lack of increased infection rates after fracture fixation. Caution should be applied when considering PPP in patients with associated acetabular fractures.
Level Of Evidence:
Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
