*3.3.1.2 Breech presentation*

The breech presentation has been implicated as a risk factor in DDH [4]; products with breech presentation, have twice the risk of DDH [23], the risk is strengthened if it is with the pelvic extremities in extension and intrauterine adduction [10]. Another mechanism is the traction of the pelvic extremities, exerting pressure on the hips for the extraction of a product with breech presentation [11].
