Brief summary
Although several studies have studied the predictive nature of non-accidental trauma of the different types of fractures and in particular on the femur, the physiological and radiological particularities of the child make it difficult to estimate the age of a fracture and require defining a chronology specific to the specificities of the pediatric population. Some authors have carried out work for the dating of fractures, however the number of cases or the average age of the subjects does not allow a precise estimation of the chronology of evolution of the fractures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Define retrospectively the chronology of the appearance of periosteal callus, secondary callus and remodeling phenomena from the study of radiographs of the femur | Files analysed retrospectively from January 01, 2007 to December 31, 2020 will be examined | Evaluation of the time to radiographic appearance of the following stages defined by the number of days elapsed between the date of diagnosis of the fracture and the first radiography taken during follow-up, making it possible to highlight one of these phenomena: * The radiographic periosteal reaction (or periosteal callus) defined by an opacity at the periphery of the fracture, corresponding to the first objectifiable calcification of the fracture hematoma and under the periosteum. * The secondary bone callus (or osteochondral) defined by a well-defined bone apposition of density close to that of the bone with opacification of the fracture line and union of the fracture site * Established remodeling activity when phenomena of axis correction, resorption of initial callus hypertrophy or re-permeabilizatio of the diaphyseal shaft can be demonstrated |
