Miscellaneous Flashcards
Angle of inclination
frontal plane of angle between neck and shaft of femur 125 degrees
Coxa Valga
Angle of inclination more than 125
Coxa Varus
less than 125 degrees
Torision
femur naturally twisted along it’s axis
normal anteversion
15 degree torision angle
retroversion
torosion less than 15
Transverse acetabular ligament
spans acetabular notch, completing the cup of the acetabulum
Ligamentous teres
provide femoral head with blood
Coxa Velga
angle of inclination less than 15
ASIS located on
Illium
Illiofemoral, ischiofemoraland pubofemoral ligaments
limit extension of hip
anterior pelvic tilt
Short-arc pelvic on femoral hip flexion with the trunk remaining essentialy upright
Hiking on right side of pelvis
motion os closed chain abd of left hip motion involves left glut med
Obturator nerve innervates
Adductors
action that occurs in the horizontal plane
Hip internal rotation
Primary hip flexor?
Illiopsoas
muscles that produce posterior pelvic tilt
Glut Max Rectus Abd
Anterior Pelvic Tilt
Increasing Lordosis of Spine
Abs are weak resisted hip flexion will cause
Increasing Lordosis of Spine
Posterior Pelvic Tilt
Decreases Lordosis of Spine
Hip is flexed to 70 degrees
adductors have a favorable line of pull to preform hip extension
Not an action of the Glute Max
Internal rotation
When illiopsoas is stretched pelvis must be stabilized to prevent
Unwanted Lordosis
During normal standing weight where does the body lean?
posterior
posterior pelvic tilt is accompanied by
decreasing lordosis at spine
Tredelenburg
weak Abductors
Normal Genu Valgum
170-175 degrees
primary ligament involved in resisting large valgus producing forces of knee
medial collateral ligament
Terrible Triad
injury of medialcollateral ligament anterior cruciate ligament medial meniscus
medial and lateral menisci
absorb and disperse comprehensive forces between the tibia and femur
screw home mechanisim
absorb and disperse compressive forces between the tibia and femur
genu recurvatum
a knee that displays marked hyperextension
patella
Increases the internal movement arm of the quads enhancing knee extension torque
extensor lag
inability to complete the final few degrees of knee extension possibly due to swelling within the knee
tight hamstings
= a relative posterior pelvic tilt
multi articular muscles
vastus lateralis vastus medialis
quads are active eccentrically
knee moving into flexion
posterior cruciate ligament
reisist posterior translation of the tibia relative to a fixed femur
