Random Anatomy- Exam 2 Flashcards
Injury to superior gluteal nerve
Paralysis of gluteus medius
Trendelenburg test-pelvis descends to unsupported side
“Hip drop”
Gluteal gait “waddling”
Trochantric and ischial bursitis
Point tenderness over greater trochanter
Excessive friction (cycling) “pain in the butt bone”
Hamstring injuries
Common in runners
Tear from attachment (ischial tuberosity)
Injury to sciatic nerve
Compression of sciatic nerve by piriformis- piriformis syndrome
Wound or surgery on medial side ➡️ injury to sciatic nerve ➡️ paralysis of hamstring ➡️ inability to extend and flex leg
Intragluteal injection
Superolatetal quadrant is safe area for injection
Tibialis anterior strain
“Shin splint”
Pain and inflammation of distal 2/3 of tibia
Common in runners
Tear in periosteum or point of attachment of TA
Can be avoided by proper warm up and cool down
Injury to common fibular nerve
High risk of injury due to anatomical location
FOOT DROP
Making the limb “too long”
Paralysis of all muscles of anterior and lateral compartments (dorsiflexors of ankle and evertors of foot)
Loss of sensation on anterolateral leg & dorsum of foot
Compensations: waddling gait, swing-out gait, high stepping stoppage gait
“Ski boot syndrome”
Deep fibular nerve entrapment
Pain in anterior compartment
Compression by tight fitting ski boots at extensor retinaculum
Soccer player, runners and use of tight shoes
Superficial fibular nerve entrapment
Chronic ankle pain
Numbness and paresthesia
First sign of PVD
Weak or absent dorsal is pedis pulses
Tennis leg
Gastrocnemius strain
At musculotendinous junction
By over stretching; full extension of knee and dorsiflexion of ankle
Posterior tibial pulse
Palpated b/w medial malleolus and calcaneal tendon
Invert the foot
Signs of peripheral arterial disease
- Weak or absent pulses
- Intermittent claudication
- Atherosclerosis
Tibial nerve injury
Deep laceration or posterior dislocation of knee
Inability to plantarflex
Calcaneal tendon reflex
Tests S1 and S2 roots
Absent reflex in damage to spinal cord
Calcaneal bursitis
Common sports injury
Pain posterior to heel
Due to excessive friction of bursa
Femoral hernia
Protrusion of loop of guy through femoral ring (weak spot)
More common in women bc wider pelvis
Hernia may become subcutaneous after passing through saphenous opening
Strangulation of hernia is a surgical emergency ➡️ bowel obstruction
Femoral artery pulse and cannulation
Strong pulsation inferior to inguinal ligament
Weak or absent if kink in aorta
Can be compressed to control bleeding
Used for left heart cath
Femoral vein pulse and cannulation
Not palpable
Great saphenous vein empties 3 cm inferior to inguinal ligament
Right heart cath to measure PCWP
Lumbar plexus
L1-L4
Sacral plexus
L4-S4
Structures perforating diaphragm:
T8-IVC
T10- esophagus, vagus
T12- aorta
I 8 10 Eggs At 12
How many vertebrae are there?
In each section?
33 7 cervical 12 thoracic (for 12 thoracic ribs) 5 lumbar 5 sacral (fused) 4 coccygeal (fused)
Length of spinal cord
Extends from foramen magnum to L1/L2 in adult and L3 in new born
(Moves up with age)
41-48cm long
