    "abstract": "Our study analyzed the incidence of posterior pelvic injury patterns and their influence on the surgical treatment of transverse-oriented acetabular fractures .\nFifty-one transverse-oriented acetabular fracture cases admitted between 1999 and 2013 were evaluated retrospectively. Comparative studies were performed for groups organized by acetabular fracture type, degree of sacroiliac separation, and postoperative reduction quality .\nAssociated posterior pelvic injuries were found in 34 (66.7%) of the 51 patients. There were 32 sacroiliac separations in the 34 patients with associated posterior pelvic injury, and ipsilateral sacroiliac separations were more frequent in this subgroup. Measurements guided by computerized tomography showed that 16 sacroiliac separations were \u22640.5 cm (mean=0.43\u00b10.14 cm), 10 were 0.5-1 cm (mean=0.73\u00b10.17 cm), and the remaining 6 were >1 cm (mean=1.55\u00b10.15 cm). In the group of 34 patients with associated posterior pelvic injury, acetabular reduction was anatomic in 19 (55.9%) patients, imperfect in 10 (29.4%) patients, and poor in 5 (14.7%) patients. For isolated acetabular fractures, reduction rates were as follows: 12 (70.6%) anatomic, 3 (17.6%) imperfect, and 2 (11.8%) poor. The rate of anatomic reduction was significantly higher when sacroiliac separation was \u22640.5 cm (p=0.027) .\nAssociated posterior pelvic injuries, especially ipsilateral sacroiliac joint separation, accompany most transverse-oriented acetabular fractures and may influence the quality of acetabular reduction. Level of Evidence III, Therapeutic Studies Investigating the Results of Treatment.\nNosso estudo analisou a incid\u00eancia de padr\u00f5es de les\u00e3o p\u00e9lvica posterior e sua influ\u00eancia no tratamento cir\u00fargico das fraturas do acet\u00e1bulo com orienta\u00e7\u00e3o transversal.\nCinquenta e um casos de fratura acetabular com orienta\u00e7\u00e3o transversal foram avaliados retrospectivamente entre 1999 e 2013. Foram realizados estudos comparativos para grupos formados de acordo com o tipo de fratura acetabular, grau de separa\u00e7\u00e3o sacroil\u00edaca e qualidade da redu\u00e7\u00e3o no p\u00f3s-operat\u00f3rio.\nConstataram-se les\u00f5es p\u00e9lvicas posteriores associadas em 34 (66,7%) dos 51 pacientes. Havia 32 separa\u00e7\u00f5es sacroil\u00edacas nos 34 pacientes com les\u00e3o p\u00e9lvica posterior associada, e as separa\u00e7\u00f5es sacroil\u00edacas ipsilaterais foram mais frequentes nesse subgrupo. De acordo com medi\u00e7\u00f5es guiadas por tomografia computadorizada, 16 separa\u00e7\u00f5es sacroil\u00edacas foram \u2264 0,5 cm (m\u00e9dia = 0,43 \u00b1 0,14 cm), 10 estavam entre 0,5 e 1 cm (m\u00e9dia = 0,73 \u00b1 0,17 cm) e os 6 restantes foram >1 cm (m\u00e9dia = 1,55 \u00b1 0,15 cm). No grupo de 34 pacientes com les\u00e3o p\u00e9lvica posterior, a redu\u00e7\u00e3o acetabular foi anat\u00f4mica em 19 (55,9%) pacientes, imperfeita em 10 (29,4%) pacientes e deficiente em5 (14,7%) pacientes. Nas fraturas acetabulares, as taxas de redu\u00e7\u00e3o foram as seguintes: 12 (70,6%) anat\u00f4micas, 3 (17,6%) imperfeitas e 2 (11,8%) deficientes. A taxa de redu\u00e7\u00e3o anat\u00f4mica foi significativamente maior quando o grau de separa\u00e7\u00e3o sacroil\u00edaca foi \u2264 0,5 cm (p = 0,027).\nAs les\u00f5es p\u00e9lvicas posteriores associadas, especialmente a separa\u00e7\u00e3o da articula\u00e7\u00e3o sacroil\u00edaca ipsilateral, acompanham a maioria das fraturas do acet\u00e1bulo com orienta\u00e7\u00e3o transversal e podem influenciar a qualidade da redu\u00e7\u00e3o acetabular.
