-
What type of joint is the hip joint, and what are the articulations?
ball and socket, triaxial
head of femur articulates with the acetabulum
-
What is the acetabulum formed from?
ilium, ishium, pubis
-
What mvmts do you get at the hip?
- flex/ext/hyperext
- abd/add
- IR/ER
- circumduction
- horizontal abd/add (flex hip and knee)
-
What is the head of the femur covered in?
articular cartilage
-
What is the attachment for the gluteus medius/minimus, and most deep rotators?
greater trochanter
-
What is the attachment for the iliopsoas?
lesser trochanter
-
What is the linea aspera?
prominent ridge that runs most of the posterior length of the femur (on back)
attachment for many hip and knee mm.
-
What is the adductor tubercle?
- small projection proximal to the medial epicondyle
- attachment for the adductor magnus
-
What is the patellar surface?
- between medial and lateral condyles
- ant. side, smoothed out portion
- articulates with post. surface of patella
-
What is the pectineal line?
- proximal part of femur
- attachment for adductor brevis and pectineus

What is the lg projection at the proximal end of the midline and is the attachment for the quads muscle tendon?
tibial tuberosity
-
What is around the rim of the acetabulum?
- acetabular labrum
- deepens acetabulum
-
What ligament anteriorly reinforces the jt capsule?
iliofemoral lig/ Y lig/ lig of Bigelow
- AIIS splits to the intertrochanteric line of femur
- limits hyperextension
-
What ligament reinforces the jt capsule medially and laterally?
pubofemoral lig
- medial acetabular ring and superior ramus of pubis to neck of femur
- limits hyperextension and abduction
-
What ligament posteriorly covers the jt capsule?
ischiofemoral lig
- ishial part of acetabulum to neck of femur
- limits hyperextension and IR
-
What small ligament is within the jt capsule (intracapsular)?
ligamentum teres
- contains blood vessels to supply head of femur
- proximally in acetabulum -> distally in fovea of femoral head
-
What is the iliotibial band?
ITB, IT band, iliotibial tract
- long tendinous portion of tensor fascia latae m. (TFL)
