This is an excerpt from the content

Posterior hip dislocation in adults generally is viewed to be a result of high-velocity trauma, typically an impact of the knee against the dashboard or high-energy sports injury, while little attention has been paid to the experience that traumatic posterior dislocations sometimes occur after minor trauma. Four recent publications [5, 8, 10, 11] suggest that femoroacetabular impingement (FAI) may cause this type of “motion-induced” hip instability [1], resulting in hip dislocation after varying degrees of trauma, including, sometimes, lower-energy impacts when they occur against a flexed and internally rotated hip.

In the past, traumatic dislocation has been thought to be a function of some degree of inherent hip instability, perhaps from reduced coverage of the femoral head; however, traumatic hip dislocation rarely is seen in hips with acetabular dysplasia. The abovementioned recent observations [5, 8, 10, 11] support the speculation that leverage, rather than insufficient coverage, ...
