ANAT 1019 Lower Limb UPDATED
ACTUAL Exam Questions and CORRECT
Answers
SIJ (2)
(name, joint type, articulation, movement) - CORRECT ANSWER - Sacro-iliac joint
Iliac tuberosity -- sacral tuberosity (fibrous syndesmosis)
Iliac auricular surfaces-- sacral auricular surfaces (synovial plane joint)
Little movement: stability against shearing forces
Sacral Nutation - CORRECT ANSWER - Anterior tilt of sacrum relative to ilium. Base of the
sacrum moves anteriorly and inferiorly. Forming closed packed position.
SIJ Ligaments - CORRECT ANSWER - (post) dorsal sacroiliac ligament
interosseous sacroiliac ligaments (deep)
(ant) ventral sacroiliac ligaments
sacrospinous ligament
sacrotuberous ligament
Acetabulum Parts - CORRECT ANSWER - acetabular fossa (non-weightbearing)
lunate surface (weightbearing)
acetabular notch
transverse acetabular ligament
Femoral Anteversion - CORRECT ANSWER - 15*. Femoral head is anterior relative to
femoral condyles (angle formed between neck and shaft)
Neck Shaft angle
, (pathology= decreased , increased) - CORRECT ANSWER - 120-135*
Coxa Vara: neck shaft angle more than 135 --> femoral neck more horizontal position increases
weight bearing --> increase shear force --> increases bending moment on neck --> increases
fractures
Coxa Valga: neck shaft angle less than 120* --> weight bearing is more parallel with head of
femur --> increase compression forces on femur neck --> decreases shear forces --> decreases
moment arm of gluteus medius --> decreases force output --> increases valgus forces -->
increases stress in knee compartment
HJ
(Name, joint type, articulation, movement) - CORRECT ANSWER - Hip joint
Multiaxial synovial Ball and Socket
HJ Ligaments ( 3 capsular + 2 + Labrum) (resists) - CORRECT ANSWER - Capsular :
iliofemoral (strongest) (Lat Rot)
ischiofemoral ligament (Med Rot in ABD)
pubofemoral ligament (ABD)
transverse acetabular ligament
ligamentum teres
acetabular labrum
HJ
pathology - CORRECT ANSWER - loose packed position allows more room in flexion to
accomodate swelling
Gerdy's tubercle - CORRECT ANSWER - ITB
Femoral Triangle
(borders, contents) - CORRECT ANSWER - inguinal ligament, sartorius, adductor longus
