Lower extremity - joints and ligaments Flashcards
what are the three joints of the pelvic and hip area?
sacroiliac, public symphysis, hip
what is the classification of the sacroiliac joint?
synovial plane (gliding)
what is the movement of the sacroiliac joint?
slight contribution to pelvic movements
What is the classification for hip joint?
Synovial ball and socket
what are the movements for hip joint?
F/E, Abd/Add, medial and lateral rotation, circumduction
What are the knee joints?
Knee joint and superior tibiofibular
Knee joint
Class: synovial bi-condylar complex hinge
movmt: FE, Medial/lateral rotation
Superior tibial fibular
class: synovial plane (gliding)
major joints of the foot

What bones are involved in the hip joint?
Head of femur and acetabulum of pelvis
what bones are involved in the knee joint?
femoral lateral and medial condyles, with tibial lateral and medial condyles, patella,
what bones are involved in superior tibiofibular joint?
tibia and fibula
What bones are invovled in talocrural joint?
Talus, tibia and fibia
what bones are involved in the talcalcaneal joint?
talus and calcaneus
what bones are involved in the tarsometatarsal joint
cuneiform and metatarsals
what bones are involed in the metatarsophalangeal
metatarsals and phalangeals
what bones are involved in the interphalangeal joints?

Sacrotuberous ligament
poster sup. iliac spine and lateral margin of posterior sacrum to ischial tuberosity
Sacrospinous ligament
ischial spine to lateral margin of sacrum
fibrous joint capsule of hip att.
margin of acetabulum to neck, intertrochanteric line and crest of femur
iliofemoral ligament
ant. inf. iliac spine to intertrochanteric line of femur.
what is function of iliofemoral ligament?
limits extension of femur
pubofemoral ligament
from iliopubic eminence and superior pubic ramus to fibrous capsule.
function of pubofemoral ligament?
limits abduction of femur
Ischiofemoral ligament
from ischium post. to acetabulum to greater trochanter and iliofemoral ligament.
function of ischiofemoral?
assist the iliofemoral in limiting extension of femur
Ligament of the femoral head
from fovea of the femoral head to the acetabular notch
fibrous capsule of knee
margins of femoral and tibial condyles
Medial collateral ligament
also known as tibial CL, from medial epicondyle (femur) to medial condyle and shaft of tibia
Lateral Collateral Ligament
Fibular CL, lateral epicondyle of femur to the head of the fibula.
