Clinical Correlations- Lower Limb Flashcards
compression of sciatic nerve
hypertrophy or spasm of piriformis muscle
most common in athletes
sensory changes in thigh- femoral
anterior thigh, medial knee, medial aspect of leg
sensory changes in thigh- obturator
medial thigh
sensory changes in thigh- sciatic
mid-posterior thigh, knee, posterolateral leg, sole of foot
fibular neck fracture
common fibular nerve winds around neck and divides into superficial and deep fibular
presents with foot-drop
inability to dorsiflex (deep) and evert (superficial)
pes bursitis
overuse of muscles involved in pes anserinus
pes anserina
semitendinosis
gracilis
sartorius
test ACL/PCL damage
push/pull tibia, see if it moves backwards/forwards
meniscal tears
common in sports injuries
can break off and wedge between bones, locks the joint
removal = more cartilage degeneration and arthritis
unhappy triad injury
football
lateral force causes medial injury: medial meniscus, MCL, ACL
dislocated knee
best seen in lateral view caused by knee hitting dashboard in MVA damage to PCL ⅔ have associated vascular injury check for damage to popliteal artery
over-inversion of ankle (sprain)
more common than over-eversion (weaker ligaments)
lateral ligaments prevent this- calcaneofibular, anterior talofibular ligaments
trimalleolar fracture
both malleoli and distal fibula are fractured
can be caused by over-inversion
calcaneal tendon injuries
achille’s tendon
basketball- jumping
test for nerve damage in tibial fracture
deep fibular: 1st dorsal webspace
superficial fibular: rest of dorsal foot
