Impact of Associated Abdominal Injuries on Clinical and Operative Outcome in Pelvic Injuries

Study Overview
=================
Brief Summary
-----------------
Pelvic fractures are severe injuries which require advanced orthopedic surgical skills to treat. On the other hand, abdominal injuries are severe injuries, which might require quick general surgical treatment. The combination of both injuries is a challenge for orthopedic surgeons, as the abdominal injury might lead to a delayed surgical treatment of the pelvic fracture. Whether an associated abdominal injury influences the quality of care of pelvic fractures, is aim of this registry study.

Detailed Description
-----------------
The German Pelvic Registry of the German Trauma Society is a multicenter prospective registry which collects data of patients with pelvic injuries since 2003. Beside demographic data (including concomitant injuries) allowing for epidemiological evaluations of the development of surgical care in these patients, namely the operative care is focus of this registry. Beside the chosen procedure or surgical approach, this includes both intraoperative data like time until operation, duration of the procedure or intraoperative blood loss and reduction parameters (pre- and postoperative fracture steps). The clinical course is recorded also including overall morbidity, overall mortality and osteosynthesis-related complications. The influence of a concomitant abdominal trauma on the quality of care regarding operative parameters like reduction quality or the clinical course in pelvic injuries has not been investigated yet. The investigators therefore retrospectively analyze the prospective consecutive data of patients from the multicenter German Pelvic Registry of the German Trauma Society in the years 2003 - 2017. Demographic, clinical and operative parameter were recorded and compared in two groups (isolated pelvic fracture vs. combined abdominal/pelvic trauma).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| isolated pelvic fracture<br>Patients with an isolated pelvic fracture | Procedure: osteosynthesis of the pelvis<br>* Osteosynthetic Fixation of the pelvic fracture<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Matta Grading | Quality of the reduction of the pelvic fracture measured in mm residual step at the fracture's site. A residual step of 0-2mm is graded as an anatomical reduction (=Matta 1), a residual step of 2-3mm is graded as an Imperfect reduction (=Matta 2) and a residual step >3mm is graded as a poor reduction (=Matta 3). | through study completion, at least 1 year after inclusion | 
| Overall morbidity | Rate of overall complications | through study completion, at least 1 year after inclusion | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| osteosynthesis-associated complications | Rate of osteosynthesis-associated complications | through study completion, at least 1 year after inclusion | 
| length of hospital stay | Duration of the inpatient Treatment, measured in days. | through study completion, at least 1 year after inclusion | 
| Time until definitive pelvic surgery | The time until the definitive surgical procedure for the pelvic fracture, measured in days. | through study completion, at least 1 year after inclusion |
