Pelvic and Hip Trauma Flashcards
(32 cards)
What pelvic arch is the larger arch composed of iliac wings and sacrum suspended by some of the
strongest (sacroiliac) ligaments in the body?
Posterior arch
What pelvic arch is the smaller arch: pubic and the ischium bones connected by pubic ligaments and the symphysis pubis?
Anterior arch
What 3-bony pelvic ring-lines are required for fracture evaluation to establish continuity or disruption?
Pelvic inlet and both obturator foramen
What is the most common cause of pelvic fractures?
Car crash
What type of pelvic fracture is classified as a single break and is the most common type of pelvic fracture?
Stable pelvic fracture
What type of pelvic fracture is classified as a break and/or disruption in 2-places or more?
Unstable pelvic fracture
Who are most prone to an Apophyseal avulsion fracture of the hip and pelvis?
physically active adolescents and young adults (14-25 year olds)
How does an apophyseal avulsion occur?
Sudden, forceful muscular contraction
What type of pelvic fracture is a stable iliac wing fracture resulting from a direct blow?
Duverney fracture
What type of pelvic fracture is unstable and involves vertical shear force, ipsilateral hemipelvic fracture through ipsilateral pubic rami and sacroiliac joint or sacral ala, and is the most common 1/3 of all pelvic fractures
Malgaigne fracture
What is the clinical manifestation of Malgaigne fracture?
short limb on the side of fracture
What type of pelvic fracture results from lateral compression force (car accidents) and vertically-orientated fractures through the superior and inferior pubic rami on one side?
Bucket handle fracture
With Bucket handle fracture, what side of the body does sacro-iliac joint disruption occur in?
Contralateral
What kind of pelvic fracture occurs classically through the superior pubic rami and ischiopubic junction bilaterally and is often accompanied by a serious bladder and urethral injury?
Straddle pelvic fracture
What kind of pelvic fracture is due to forced separation of the posterior ring through one or both sacroiliac joints with disruption of the pubis symphysis and anterior ring diastasis?
Sprung-pelvis fracture-dislocation
What is another name for Sprung-pelvis fracture-dislocation?
Open-Book pelvis
Who are predisposed to proximal femur fractures?
old, osteoporotic patients
In the elderly, what is usually the cause of a proximal femur fracture?
Low impact trauma
What kind of proximal femur fracture is important because of their propensity to damage the small intracapsular vessels that provide the majority of the blood supply to the femoral head as seen in subcapital, mid and basi-cervical fractures?
Intra-capsular fractures
What kind of proximal femur fracture does not usually cause vascular damage?
Extracapsular fractures
Give 2 examples of extra-capsular fractures?
Trochanteric and subtrochanteric fractures
What type of classification is of Femoral neck fractures used to determine and predict stability and associated complications with required treatment of subcapital neck fractures?
Garden classification
What is the key feature for Garden classification?
Whether the fracture is intra or extra-capsular
What type of Garden classification is incomplete and minimally displaced?
Type 1
