Q

An avulsion Fx of rectum femoris is MC in what population?

Study These Flashcards
A

Young athletes

24
Q

MC unstable Fx in pelvis?

25
Hip Fx MC in what population?
F>M Elderly, predisposed via osteoporosis, pagers, fibrous dysplasia, malignancies, osteomalacia, osteonecrosis
26
MC intracapsular (AKA proximal to trochanters) Fx
Subcapital: may be impacted or displaced. May see sclerotic-like white band. Worry about strong mm contraction in elderly osteoporotic folks breaking hip before fall. Proximal femur Fx classifications: 1. Intracapsular (subcapital, midcervical, basicervical) 2. Extracapsular (intertrochanteric, subtrochanteric, trochanteric)
27
3 Pathological proximal femur Fx?
Basicervical Subtrochanteric Trochanteric
28
MC complication of slipped femoral capital epiphysis?
DJD
30
MC place for lipohemarthrosis to occur? Describe
Knee (can occur in shoulder too) Marrow fat is pushed into joint fluid with blood. FBI (fat blood interface) sign in suprapatellar bursa seen on lateral xray
31
MC population for osteochondritis dissecans? MC location?
Population: teens Location: lateral femoral condyle A subchondral lesion of bone that breaks off and gets lost in the joint.
32
MC location for proximal tibia Fx? MC population?
Location: 80% on the lateral plateau Population: elderly, osteoporotic Bumper or fender Fx is when femoral condyle impact the tibia plateau. Can injure ligaments
33
MC population for avulsion of anterior tibial spine? MOI?
Children from falling off bikes
34
MC kind of patellar Fx?
Transverse or slightly oblique
35
MC epiphyseal injury?
Harris Salter #2 Fx through epiphysis with piece of shaft attached Harris Salter classification 1 - Epiphyseal slip only 2 - Fx through epiphysis with piece of shaft attached - MC 3 - Fx through epiphysis extending through the epiphyseal plate 4 - Fx of epiphysis and shaft - going through epiphyseal plate 5 - Damage to epiphyseal plate
36
MC location for calcaneal foot fracture?
Mid-calcaneus aka stress fx
37
MC location for talus Fx?
Anterior surface avulsion AKA aviator’s Fx Vertical Fx line extends through Tamar neck. They were first described in WWI when pilots involved in crash landings had the rudder pedal forced into the sole of the foot.
38
MC location for navicular Fx?
Dorsal cortical surface avulsion
39
MC metatarsals to get a stress Fx? MC population to get this?
Necks of 2nd or 3rd AKA March Fx: MC in military recruits and believed to be d/t fatigue of the peroneus longus muscle leading to instability of the foot
40
MC bony injury in the foot?
March Fx of the metatarsals (MC 2nd or 3rd)
41
MC sternal Fx MOI?
Compressive blunt trauma
42
MC location for claivcal Fx?
Middle 80%
43
MC Fx in kids / in the elbow?
Supracondylar Fx: transverse or oblique Fx above the condyles 60% of elbow fx in kids occurs here
44
MC population to get epicondylar fx ?
Children AKA “little leaguer’s elbow” or avulsion Fx — the medial epicondyle is separated from the act of e.g. throwing
45
MC Fx at the elbow in adults? MOI?
Radial head 50% D/t FOOSH and transmitting longitudinal axis of force to create impaction of proximal radial head
47
MC location for forearm / “both bones” Fx?
60% of the time radius AND ulnar both break mid-shaft
48
MC elbow Fx in elderly? MOI?
Colles Fx | MOI: FOOSH
49
MC age group to get a torus Fx?
6-10 yo Torus Fx: MC fx of the wrist MOI: axial trauma. On x-ray looks like cortical bump or bulge
50
2nd MC carpal/wrist Fx?
Triquetrum Fx (look for a small, displaced flake on lateral view)
51
What is the MC fx site in the whole body?
Phalanges
52
Top 3 dislocation sites in adults
1 - shoulder 2 - interphalangeal joints 3 - elbow
53
Type dislocation site in children
Elbow
54
MC dislocation vector of the elbow?
Posterior and posterolateral
55
MC carpal instability location?
Scapholunate dissociation AKA rotary subluxation of scaphoid
56
MC fractured metacarpal?
5th
57
MC dislocated carpal?
Lunate and then scaphoid
58
MC type of 1st metacarpal Fx?
Transverse Fx
61
MC hip dislocation?
Posterior (Superior and posterior)
