fractures Flashcards
what tendon is involved
adductors
this is on the sports hernia spectrum
common in adolescent athletes with recently fused apophysis
what is a stieda fracture?
medial femoral condyle avulsion
stieda pelligrini
remote mcl injury
what is a key dynamic stabilizer of the PMC
semimembranosus
3 tendons associated with PMC
oblique popliteal ligament, posterior oblique ligament, semimembranosis
predisposing factors to transient patellar dislocation
patella alta and trochlear dysplasia
describe the difference between PCL avulsion fracture and a meniscal ossicle
PCL avulsion fracture
most common MOA of PCL tear
#1 type of PCL injury is from:
“dashboard injury” = traslation of the tibia on the femur with the knee in flexion
#2 most common PCL injury = hyperextension
dashboard injury is likely to result in what knee ligament injury?
PCL
classification system for shoulder fractures
Neer
Bennett fx
fracture at the base of the first metacarpal
Rolando fx
comminuted Y shaped fracture at the base of the first metacarpal
Complication of a Bennett fracture?
Dorsolateral dislocation of the fracture fragment secondary to the pull of the abductor pollicus longus
What is Gamekeeper’s thumb?
avulsion fracture at the base of the proximal first phalanx associated with ulnar collateral ligament disruption.
What is the most common carpal bone fracture?
schapoid
salther harris classification?
SH4
ATFL tear
most common ligament torn in the ankle (weakest ligament in the lateral collateral ligament complex)
fallen fragment sign
pathologic fx through a simple bone cyst
intramedullary, metaphysis of long bones
abuts the growth plate
treatment: IF SYMPTOMATIC intralesional steroids for large cysts; or surgery with curettage and bone grafting
