Abos - Hip & Femur - Hip:pathologic States - Acetabular & Femoral Osteotomises: Adults

Front 1

What are the three general causes of excess femoral anteversion in adults?

Back 1

Residual development dysplasia of the hip (DDH)
Total hip replacement with subsequent HO development (pelvis flexed)
Miserable malalignment syndrome

Front 2

What acetabular osteotomy is preferred for adults? What is the effect on the medical/lateral acetabular position?

Back 2

Ganz
Medializes the acetabulum

Front 3

What is an indication for femoral varus derotational osteotomy (VRDO) in an adult?

Back 3

Dysplasia with coxa valga

Front 4

With what percentage of head involvement with AVN should one consider intertrochanteric osteotomy?

Back 4

<50 % head involvement for osteotomy
Varus osteotomy if lateral head intact
Valgus osteotomy if medial head intact

Front 5

After Perthes disease, where does the femoral head generally impinge? What is the treatment?

Back 5

Impinges laterally (at osteophyte)
Treatment: valgus intertrochanteric osteotomy

Front 6

What osteotomy is preferred after slipped capital femoral epiphysis (SCFE)? Is there a caveat?

Back 6

Valgus flexion osteotomy
Caveat: no anterior closing wedge for flexion osteotomy
