Flashcards in Posterior Leg and Foot Deck (23)
Bones of the foot
Tiger Cubs Need MILC + the metatarsals (1 for each digit) and Phalanxes (2 for first digit [proximal, distal], 3 for lateral 4 digits-[proximal, intermediate, and distal])
Medial Cuneiform Tarsal
Intermediate Cuneiform Tarsal
Lateral Cuneiform Tarsal
Cuboid Cuneiform Tarsal
Function of Soleus vs Gastrocnemius
SOLEUS- Postural. Used mostly to maintain positioning when standing.
GASTROCNEMIUS- Action oriented. Used mostly when running or during general movement.
The plantaris tendon runs over what muscle?
Soleus. The tendon is also known as the "freshman nerve", as it can often be confused as a nerve.
Function of the popliteus muscle.
Allows you to unlock your knee when it is hyper-extended.
All muscles of the posterior leg function to...
Invert the foot
Structures which come around the medial side of the leg.
Tom, Dick, And Nervous Harry
-sheath of the Tibialis posterior tendon
-tendonous sheath of flexor Digitorum longus
-posterior tibial Artery
-posterior tibial Nerve
-tendonous sheath of flexor Hallucis longus
Cutaneous innervation of Superficial Fibular Nerve
Most of the dorsum of the foot except tips of toes
What does the deep fibular nerve innervate in the foot?
2 muscles (EHB, EDB) and sensory between 1st and 2nd toes.
Thickened deep fascia of the sole.
1st layer of the plantar surface (most external)
Flexor digitorum brevis
Abductor digiti minimi
2nd layer of the plantar surface
2M + 2T
Tendon of flexor digitorum longus
Tendon of flexor halluces longus
3rd layer of the plantar surface
Flexor hallucis brevis
Flexor digiti minimi brevis
4th layer of the plantar surface
2 M + 2T
Plantar interossei (PAD)
Dorsal interossei (DABS)
Tendon of fibularis longus
Tendon of tibialis posterior
Functioning of Plantar vs Dorsal Interossei
Dorsal (4): Abductors
Plantar (3): Adductors
Lateral Planter artery eventually becomes ______ and this eventually goes on to anastomose with _________
-deep plantar branch of the dorsalis pedis artery
Muscles innervated by the Medial plantar nerve
Flexor Hallucis Brevis
Flexor Digitorum Brevis
Clinical presentation of a femoral nerve injury.
Wasting of anterior thigh, leg drop, weakness in flexion, sensory loss of anterior thigh and medial leg/foot
Clinical presentation of an obturator nerve injury.
Wasting of medial thigh, loss of thigh adduction; sensory loss upper medial thigh.
Clinical presentation of a superior gluteal nerve injury.
Trendelenburg sign (pelvis tilts down on side opposite injury); no sensory loss.
Clinical presentation of an inferior gluteal nerve injury.
Wasting of buttock, weakness in thigh extension; no sensory loss.
Clinical presentation of a sciatic nerve injury.
Wasting of all hamstrings and muscles of leg/foot. Sensory loss to back of thigh and leg, lateral leg and plantar foot.
Clinical presentation of a common fibular nerve injury.
Foot drop and loss of toe extension. Sensory loss to lateral leg and dorsum of foot.
