Dissection 13 Flashcards
Pott fracture
Fracture of the distal tibia and fibula associated with ankle dislocation
Muscles and nerves responsible for flexion and the knee
Hamstrings, gastrocnemius
Tibial and common fibular nerve
Muscles and nerves responsible for extension at the knee
Quadriceps and femoral nerve
Medial rotation
Hamstrings and gracilis
Tibial and obturator nerves
Lateral rotation
Biceps femoris
Tibial and common fibular nerve
Bursa superficial to the patella
Prepatellar bursa
Bursa inferior to the patella
Infrapatellar bursa
Unhappy triad
Torn medial meniscus, medial collateral ligament, anterior cruciate ligament
Prevents anterior displacement of the tibia on the femur
ACL
Prevents posterior displacement of the tibia on the femur
PCL
This bursa is a continuation of the synovial cavity
-how can you assess if there is fluid in it?
Suprapatellar bursa
-massage test
What does the common fibular nerve divide into?
Superficial and deep
Nerve supply to muscles in lateral compartment of leg
Superficial fibular nerve
Nerve supply to muscles in anterior compartment of leg
Deep fibular nerve
Nerve supply to first interdigital cleft
Deep fibular nerve
The main actions of the muscles of the anterior compartment of the leg
Dorsiflexion of the ankle, great toe and digits
Inversion (TA and tibialis posterior)
Eversion (FT with fibularis longus and brevis)
Inversion of the foot
Tibialis anterior and posterior
Eversion of the foot
Fibularis tertius, fibularis longus, fibularis brevis
Where is the dorsalis pedis artery?
Immediately lateral to the EHL tendon on the dorsum of the foot
What separates the anterior and lateral compartments of the leg?
Anterior intermuscular septum
Muscles in the lateral compartment of the leg
Fibularis longus and brevis
Muscles in the anterior compartment of the leg
Tibilias anterior
Extensor digitorum longus
Extensor hallucis longus
Fibularis tertius
Main actions of the fibularis muscles
