ALS Lecture 10 - The Lower Limb, Muscle Groups DONE Flashcards
(133 cards)
deep fascia is a _____ fibrous tissue that covers ____
fibrous, whole body under skin
it encloses different parts of the limbs into
compartments
what do compartments maximise? (2)
- maximise muscle work
- venous return
fascia lata is the
deep fascia in the thigh
fascia lata is continuous from
inguinal ligament, Scarpa’s fascia (abdomen)
fascia lata attaches to
pelvis superiorly
fascia lata runs distally down the knee, enclosing 2 muscle groups
- tensor fascia latae - hip flexors, knee extensors
2. gluteus maximus - hip abductors
2 openings of fascia lata
cribriform fascia, saphenous opening
what happens in the cribriform fascia opening of the fascia lata?
great saphenous vein drains into femoral vein
crural fascia is
continuation of fascia lata, deep fascia in the leg (knee-ankle)
crural fascia fuses to
tibia
crural fascia thickens to form the
extensor retinacula at ankle joint
label the diagram of the fasciae
done
muscles in the same compartment have the same/similar (3)
functions, blood supply, innervation
compartments of the thigh
anterior, middle, posterior
compartments of the leg
anterior, lateral, posterior
what separates the anterior and posterior compartments of the leg?
interosseous membrane
label the diagrams of the compartments of the leg and thigh
done
look at the diagrams of compartment syndrome
done
compartment syndrome is due to
increased pressure in compartment
increase in pressure could be due to (type and example, 3)
- within the compartment, e.g. intracompartmental haemorrhage
- constriction of compartment, e.g. scarring due to burns
- external compression, e.g. cast too tight
symptoms of compartment syndrome
6 Ps
pressure, pain on stretch, pulse present?, pink colour, paresis (foot drop), paraesthesia
label diagram of the 6 Ps of compartment syndrome
done
compartment syndrome treatment
fasciotomy (skin, superficial and deep fascia opened to relieve pressure)
