hip pointer
immediate knee swelling after acute injury usually indicates
intra-articular injury
difference in bilateral height of ASIS
leg length discrepancy
a condition that may occur after a contusion to the quadriceps muscle group involving abnormal ossification of bone deposition with int he muscle tissue is called
myositis ossificans
the nerve that innervates the hip adductors is the
obturator nerve
Larsen Johansson disease involves all of the following except
occurs at the tib tub

pain that is relieved when barefooted
an excessive q-angle predisposes an individual to which condition?
patella injuries
sesamoid disorders, medial tibial stress syndrome, and achilles tendinitis are all associated with
pes planus
the arcuate complex supports
posterior knee stability
weakness hip flexion and knee extension after acute injury, which muscle?
rectus femoris

slight plantar flexion and inversion with straight anterior movement
the muscles in the deep posterior compartment include all of the following except
soleus
the screw home mechanism occurs when
tibia rotates laterally on the femur during the last degrees of knee extension
The ____ nerve innervates all of the muscles in the hamstring group except the short of the biceps femoris
tibial

tibial collateral
what is not a sign of DVT
tingling or burning that radiates to the toes
Faber tests for possible SI joint pathology
true
Positive Trendelenburg test indicates weakness or instability of hip adductors
true
an acute blow to the anterior compartment can compromise the neuromuscular supply to the foot, leading to loss of dorsiflexion and extension of the toes
true
an anterior arcuate compartment syndrome is a medical emergency
true
an individual who complains of a dull ache in the mid buttock region, pain that worsens at night, weakness or numbness down the back of the leg may have piriformis syndrome
true
femoral nerve and its branches provide the primary innervation for the foot ankle and lower leg
true
for flexion to be initiated from full extension the popliteus must first act to laterally rotate the femur on the tibia unlocking or freeing the joint for motion
