P4 ANATOMY Flashcards
anatomy of hip joint
what is the type of hip joint
Synovial , ball & socket
most ligaments seen in hip joint are
( intra-capsular or extra-capsular)
Mostly extra-capsular
which joint is more stable & why
( shoulder or hip )
hip > weight bearing joint

Identify what’s pointed at by the arrow
Acetabulum
showing the acetabular fossa
name the membrane pointed by the arrow & what does it cover
obturator membrane
covering obturator fossa
showing the upper end of femur
Identify the part pointed by the arrow
inter-trochanterteric crest
showing the post. View of femur
Identify the part pointed by the arrow & its significance
Linea aspera
site of muscle attachment
A curved line, drawn on a plain film of a horizontal pelvis, helps to describe the axial relationship of a normal hip joint is known as
Shenton’s line
Ligaments of hip joint significance
1- constriction of capsule
2- draw head tightly towards acetabulum
Ligaments of hip joint disadvantage
Movement restriction ( extension )

ANT. view of hip joint
Identify the part pointed by arrow & its significant
inter-trochanteric line
site of attachment for capsule & ligaments
ANT. view of hip joint
Identify the ligament pointed by arrow
pubofemoral ligament
Most of blood supply of head of femur is by
medial circumflex femoral artery
Brancheds of deep femoral artery
- lateral circumflex
- medial circumflex
other name of the deep femoral artery
profunda femoris
Anastomoses of medial & lateral circumflex artery gives
Retinuacular branches
in case of neck of femur fracture , what arteries will be damaged & resulting in
Retinacular branches
leads to avascular necrosis
which one of the following fractures will affect the blood supply of the neck
Transcervical fracture
