Pubic

Berkebile, Fischer, & Albrecht

Recommended dorsal decubitus and lateral projection of the pelvis for “gull-wing sign” for fx dislocation of the acetabular rim and posterior dislocation of the femoral head. CR must be horizontal

AP External Oblique - Judet

Used for a px with a suspected fracture of the ilioischial column (posterior) and anterior rim of acetabulum

AP Internal Oblique - Judet

Used for a px with a suspected fracture of the iliopubic column (anterior) and posterior rim of acetabulum

Os coxae

Hip other term

Ilium

The body forms approximately two fifths of the acetabulum superiorly

ALA

Projects superiorly from the body to form the prominence of the hips

iliac crest

The superior margin extending from the ASIS to the posterior superior iliac spine

iliac fossa

Medial surface of the wings contains

pubis

Consist of a body, the superior ramus, and the inferior ramus

Superior ramus pubis

Projects inferiorly and medially from the acetabulum to the midline of the body

Inferior ramus pubis

The bone curves inferiorly then posteriorly and laterally to join the ischium

Ischium

forms approximately two fifths of the acetabulum posteriorly

pubis

forms approximately one fifth of the acetabulum anteriorly

ilium

forms approximately two fifths of the acetabulum superiorly

Ischial ramus

Projects anteriorly and medially from the tuberosity to its junction

Obturator foramen

The posterior union of the pubis rami and ischium encloses the

Ischial spine

A prominent projection at the superior border of the body

Martz and Taylor (AP)

Recommended two AP projections of the pelvis to show the relationship of the femoral head to the acetabulum in patients with congenital dislocation of the hip

Martz and Taylor – 1^st exposure

to detect any lateral or superior displacement of the femoral head

Martz and Taylor – 2nd exposure

Angulation casts the shadow of an anteriorly displaced femoral head above that of the acetabulum and the shadow of a posteriorly displaced head below that of the acetabulum

to pubic symphysis

1st expo CR martz and taylor

to pubic symphysis with cephalic angle of 45

1st expo CR martz and taylor

AP Oblique – Modified Cleaves MTD

Often called as the bilateral frog position

AP oblique – Original Cleaves

Lateral – Lauenstein and Hickey

This examination is contraindicated for patients with suspected fracture or pathologic condition

Andren & Von Rosen

Used to diagnosed congenital dislocation of the hip in newborns

Knake and Kuhns

Described the construction of a device that controlled the degree of abduction and rotation of both limbs

Axiolateral – Danelius and Miller MTD

Crosstable or surgical-lateral

Judet

Described two 45° posterior  oblique positions that are useful in diagnosing fractures of the acetabulum

15 deg posteriorly and aligned perp to the femoral neck

Modified Axiolateral – Clements and Nakayama MTD CR

Directed at the acetabulum angled 12 deg cephalad

PA Axial – Teufel MTD CR

Teufel MTD

Shows fovea capitis and acetabulum

Perp to LS region at the level of greater trochanter. Coronal plane perp to pubic symphysis

Axial - Chassard-Lapine MTD CR
