Next we're gonna talk about hip dislocations,

0:04

and here is characterizing the type of hip dislocation

0:08

on this frontal projection.

0:09

Here you can see that there's a complex pattern,

0:13

a fracture on the right pelvis,

0:15

and it appears

0:17

that the femoral head is S laterally displaced.

0:21

And then on our opterator ring view,

0:24

it becomes more apparent

0:26

that this is a posterior dislocation associated

0:29

with a fracture typically of the posterior wall.

0:32

So posterior wall fracture dislocation.

0:36

And here we have somebody who presents

0:37

with a subtrochanteric femur fracture.

0:41

So we can see the fracture line below

0:45

the lesser trocanter in that proximal diaphysis.

0:49

But if we look carefully on the lateral projection,

0:53

we can see that the femoral head is not quite situated in

0:57

the acetabulum and is more anteriorly located.

1:01

And so that represents an anterior dislocation.

1:05

So with regards to hip dislocations,

1:07

posterior is most common.

1:09

The typical deformity they may present with is an abduction,

1:13

internal rotation of the hip, anterior is less common,

1:16

being about 10%.

1:19

And here to deformity is abduction and external rotation.

1:23

So sometimes the clinical presentation

1:25

can provide the pretest likelihood

1:28

of which way the hip is dislocated

1:30

with their concomitant injuries.

1:32

Medial or central dislocations are always associated

1:36

with an acetabular fracture,

1:38

and we saw a couple of examples of those

1:41

in the section on acetabular fracture.
