24 Cards in this Set

  • Front
  • Back
Femur Neck Fracture
interruption of blood supply from medial femoral circumflex artery
quadriceps femoris, adductors, hamstrings pull distal fragment up
lower limb is shortened with lateral rotation
dislocation of femoral head
usually with age (osteoporosis)
requires hip replacement
shortened lower limb with medial rotation
Pertrochanteric fracture
femoral fracture through the trochanters
a form of extracapsular hip fracture
Dislocated knee or fractured distal femur
may injure popliteal artery because of its deep position adjacent to the femur and knee joint capsule
Transverse patellar fracture
from blow to the knee or sudden contraction of the quadriceps muscle.
proximal fragment pulled superiorly with the quadriceps tendon, distal fragment remains with the patellar ligament
Bumper Fracture
lateral tibial condyle, caused by car
associated with common peroneal nerve injury
Pott's fracture (Dupuytren's Fracture)
fracture of the lower end of the fibular, usually with medial malleolus or rupture of the deltoid ligament.
cause: forced eversion of the foot
Pilon Fracture
fracture of distal metaphysis of the tibia extending into the ankle joint
Fracture of the fibular neck
may cause injury to common peroneal nerve- results in paralysis of all muscles in the anterior and lateral compartments of the leg (dorsiflexors and everters of the foot), causing foot drop
March fracture
stress fracture
fatigue of one of the metatarsals, which may result from prolonged walking
female ballet dancers
Coxa Valga
angle axis of femoral neck to shaft exceeds 135 degrees
Coxa Vara
angle of axis of femoral neck to shaft is less than 135 degrees
Hemarthrosis
blood in a joint
usually causes a rapid swelling of the injured knee joint, (inflammatory joint effusion causes slow swelling)
Anterior drawer sign
forward sliding of tibia on femur due to rupture of the anterior cruciate ligament
Posterior drawer sign
backward sliding of the tibia on the femur, caused by rupture of the posterior cruciate ligament
medial meniscus
is more frequently torn than the lateral because of its strong attachment to the tibial collateral ligament
Unhappy Triad
cleated shoe planted, knee struck from lateral side
1. rupture of tibial collateral ligament
2. tearing of the anterior cruciate ligament
3. injury to medial meniscus
Knock-knee (genu valgum)
-tibia bent laterally
-collapse of lateral compartment of knee
-rupture of medial collateral ligament
Bowleg (genu varum)
-tibia is bent medially
-collapse of medial compartment of knee
-rupture of lateral collateral ligament
Patellar Tendon Reflex
tap on pat. tendon elicits extension
-both afferent and efferent limbs of the reflex arc in femoral nerve (L2-4)
Patella Ligament
can be used for surgical repair of the anterior cruciate ligament of the knee joint
Housemaid's Knee
inflammation and swelling of the prepatellar bursa
Gluteal gait
-gluteus medius limp
-pelvis falling toward unaffected side when the opposite leg is raised
-results from paralysis of gluteus medius muscle, which normally functions to stabilize the pelvis when opposite foot is off the ground
Intramuscular injection of drugs
superior lateral quadrant of the gluteal region
