HIP Flashcards
Ilio-femoral ligament
- strongest
- ant. aspect of joint
- prevents hyperextension while standing
Pubo-femoral ligament
limits extension and abduction
Ischio-femoral ligament
limits extension
Iliopsoas, rectus femoris, sartorius, adductors
Flexion
Extension
gluteus maximus
Hamstring (post. compartment)
Abduction
Gluteous medium, minimus
assisted by: sartorius, tensor fascia latae, piriformis
Adduction
Adductors
pectineus, gracilis
Lateral rotation
Piriformis, obturator internus
gemelli
quadratura femoris, assisted by gluteus max.
medial rotation
Gluteos medius, minimus and tensor fascia latae
relation with hip joint: anterior
iliacus
Sartorius
psoas major
pectineus
Posterior
Gluteus minimus piriformis Sciatic nerve gemelli Quadratus femoris
Arterial supply of head and neck is dependent on
Medial circumflex femoral artery
Intracapsular Fx of neck of the femur
avascular necrosis
Extracapsular Fx
reticular arteries are saved (healing faster)
Posterior dislocation of hip joint
most common
hip is flexed, adducted, medially rotated
Injury to Sciatic nerve
-paralysis of hamstrings and muscles distal to knee
Anterior dislocation of hip
extension, abduction, lateral rotation
Injury to femoral vessels and nerves
Superior medial quadrant
injury Abductor lurch
inferior lateral quadrant
difficulty climbing stairs or raising from chair
inferior medial quadrant
Sciatic nerve, “Foot drop”
inferior gluteal n. injury
paralysis of gluteus max.
- difficulty climbing stairs/ raising from chair
- Weakened: extension and lateral rotation of thigh
injury to superior gluteal nerve
-paralysis gluteus medius/ minimus
-Waddling gait
Positive Trendelenburg sign
