Chapter 17 Pelvis Flashcards
A long bone, is the longest, strongest, and heaviest bone in the body
Femur
Is the angle between the shaft and neck of the femur in a frontal plane
Angle of inclination
Is the angle between the shaft and the neck of the femur in the horizontal plane
Femoral Torsion
The condition where the femoral head slides superiorly without full dislocation of the hip
Hip Dysplasia
Occurs when an unusual shallow acetabulum does not cover the femoral head adequately
Congenital hip dislocation
Condition in which the femoral head undergoes necrosis it usually presents in children between 5 and 10 years of age
Legg-Calve-Perthes disease
Condition in which the apices of the femur slips from its normal position. Usually occurs during years when children experience increased rates of bone growth.
Slipped Capital femoral epiphysis
An angle of inclination greater than 125°
Coxa Valga
An angle of inclination less than 125°
Coxa Vara
The amount of twist between the head/neck of the femur and the femoral shaft
Femoral Torsion
is the position when the line drawn through the head/neck of the femur places, the head of the femur and tear to the greater trochanter. The normal amount of angle is 15° when compared with the line drawn through the femoral condyles.
Anteversion
Occurs when the angle of torsion is greater than 15°, the amount of medial rotation on the head and neck of the femur on the shaft of the femur is increased
Excessive anteversion
Occurs when the angle of torsion is less than 15°, the amount of lateral rotation of the neck on the shaft of the femur is increased
Excessive Retroversion
Degeneration of the articular cartilage of the hip, often resulting from trauma or wearing and tear typically seen later in life
Osteoarthritis
Predominantly intertrochanteric fractures and fractures of the femoral neck
Hip Fractures
