Hip Joint Flashcards
Structures in hip Joint
Head of femur Acetabulum Labrum Ligaments Illiofemoral Pubofemoral Ischiofemoral Ligamentum teres
Angle btw the femoral neck and the medial side of the femoral shaft is
Angle of inclination
Angle of incination in adults
Newborns
125
140-150
Coxa vara
Coxa valga
Less than 125 angle if inclination
Greater than 125
Femoral torsion angle
Relative rotation btw shaft and neck of the femur
Adult measure 10-15 of antreversion
Newborn 30 degrees of antreversion
Which reduces at 6 years of age
Which torsion angle causes toeing or pigeon toes
Excessive anterversion
Function of illiofemoral ligaments
Thickest bone in the body
Prevent extreme hip extension
Support body weight in pathological conditions like cerebral palsy
Closed pack position of the hip
Articular surface is congruent and ligaments are maximally taut
Example of closed chain and open chain
F on P i.e femoral on pelvic
Closed. Squat, stance phase of gait
Open .. hip extension exercises.. swing gait phase
Passive hip flexion and extension is degrees
Hip Flex of 80-90 in limited by hamstring in flexed knee
Hip extension is 20 defree
F on p motion angles
Abduction-40
Adduc— 25
Internal rotation—- 35
External rota— 45
Example of ipsi lateral and contra directional lumbopelvic rhythm
Ipsi… extending the reaching capacity of upper extremity
Contra—- walking dancing
Degrees on pelvic of femoral movement
Standing flexion—-80-90 ipsi- directional
Standing extension 20 —- contra directional
Pelvic tilt
Pelvic on femoral movement is limited by
Lymber spine rotational movement
If the lumber spine rotation accompanies hip rotation what happenes
Hip rotation becomes limited by hip joint capsular
