clinical conditions of the lower limb Flashcards
what movement is controlled by the L2 myotome
hip flexion
what movement is controlled by the L3 myotome
knee extension and hip abduction
what movement is controlled by the L4 myotome
ankle dorsiflexion
what movement is controlled by the L5 myotome
big toe extension
what movement is controlled by the S1 myotome
ankle plantar flexion
what movement is controlled by the S2 myotome
knee flexion
what allows for distension of the femoral vein during exercise
the femoral canal which is an empty space found in the femoral sheath
what is found at the mid point of the injuinal ligament
femoral artery
what is found at the mid inguinal point
femoral artery
what is the mid inguinal point
half way between the ASIS and pubic symphysis
what is a bakers cyst
inflammation and swelling of the semimembranosus burse in the knee
what does an aneurysm in the popliteal fossa affect the most
tibial nerve
what nerve is damaged in Trendelenburg gait
superior gluteal nerve
what nerve is damaged in foot drop
deep peroneal nerve
what can cause foot drop
tight fitting shoes compressing the extensor retinaculum
damage to the head of the fibula
what is piriformis syndrome
the piriformis compresses the sciatic nerve giving sciatica due to ill formation
what can block the knee to keep it locked
torn meniscus or pieces of bone
what is housemaids knee
prepatella bursitis
what is clergymmans knee
infrapatella bursitis
how do you asses collateral ligament of the knee damage
through medial and lateral rotation
how is the ACL torn
hyperextension or force to the back of the knee
how is the PCL torn
when the knee is flexed and force hits
what is the unhappy triad
ACL, medial collateral ligament and medial meniscus
how is the limb seen in a hip dislocation
shortened and medially rotated
what is an intracapsular fracture
fractures of the femoral neck (inside the fibrous capsule)
what artery is affected in an intracapsular fracture
medial circumflex artery
what is at risk of happening in an intracapsular fracture
AVN of the femur head
what would be the treatment for an intracapsular fracture
total hip replacement and not dynamic screws as the bone is dead
how is the leg seen in intertrochanteric fractures
shortened and laterally rotated
