Pelvic Ring Fractures: New Analysis Method and Treatment Decision Algorithm (BASSINJO)

Pelvic ring fractures are common and often the result of high energy trauma but also sometimes of lower energy trauma in older patients. A good classification and description of the fracture is essential to the choice of treatment.

The classifications used to describe these fractures are numerous (Tile modified AO, Young and Burgess, Letournel, Rommens) and of a descriptive order more or less depending on the lesion mechanism allowing some to orient the surgical reduction technique. However, none of them helps with the choice of surgical or functional treatment, which is currently based on obvious notions of instability and / or displacement of lesions and, by habit, all different services.

In addition, the complexity of these classifications leads to poor reproducibility of these.

A new method for analyzing unitary lesions has been developed in the Orthopedic Surgery department of the Paris Saint-Joseph Hospital Group with a rating system which determines the indication according to the score.

Teaching this new method of analyzing pelvic ring fractures would simplify decision making between surgical and functional treatment.

Cohorts and Interventions

Group / Cohort
Patients with pelvic ring fractures; This retrospective study will be carried out on the data of patients who have received treatment or followed for a pelvic ring fracture, in the Orthopedic Surgery department of the Paris Saint-Joseph Hospital Group between January 2015 and September 2019.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
State of play of the decision for surgical sanction of pelvic ring fractures	This corresponds to the number of patients for whom surgical decisions have been made.	Day 1

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Impact of the teaching of the new method of analysis on the surgical decision within each group	This corresponds to the number of files for which surgical decision-making was modified before and after teaching of the new method of analysis.	Day 1
Reproducibility of this intra and inter-group decision before and after teaching	This corresponds to the number of files for which surgical decision-making was modified before and after teaching of the new method of analysis in intra and inter-group.	Day 1
