Brief Summary
The purpose of this retrospective work is to study the consequences of obstetrical brachial plexus paralysis on the rotator muscles of the shoulder. First of all, the investigators want to study the reproducibility of the isometric contraction forces of the rotator muscles of the shoulder thanks to an isokinetic dynamometer. The investigatorsthen want to compare the measurements obtained from the paralyzed side compared to the healthy side. The preoperative MRI performed will be studied in search of amyotrophy. These data will be compared with those of the isokinetic assessment to identify children requiring muscle transfer of reinforcement of the external rotator muscles.

Outcome Measures
Primary Outcomes (1)
atrophy
The amyotrophy will be quantified by an index corresponding to the maximum muscle thickness measured on the MRI in T2 on the axial section passing under the spine of the scapula, between the injured side and the healthy side. This index will be measured from preoperative MRI of children. The existence of amyotrophy will be defined by an index \<0.5
1 day
Secondary Outcomes (1)
active external or internal rotation deficit
