Block 3: GL 22 Gray's Review Flashcards
What is Trendelenberg Sign
dropped hip over the swing limb is exhibited when a patient is asked to stand (the unaffected limb will droop)
What is the cause of Trendelenberg Sign?
superior gluteal nerve damage
Result of a Positive Trendelenberg Sign
patient’s gait is abnormal, patient will exhibit lateral leaning to the affected side to compensate
What are the ligaments of the hip?
iliofemoral (most anterior)
pubofemoral
ischiofemoral
Where do gluteal injections need to be done?
anterior upper outer (lateral) quadrant of the gluteal region
specifically, lateral to the highest point on the iliac crest
Why do gluteal injections need to be done in the upper outer quadrant of the hip
b/c it’s the safest place to avoid hitting the sciatic nerve and any other vessels that run through the region
Describe the orientation of the ligaments of the hip and explain why this is important
The ligaments of the hip are oriented in a spiral fashion to become taught when the joint is extended
Dual purpose: 1. stabilize the joint; 2. decrease the muscle energy needed to maintain standing position
Which hip joint is most important? Why?
iliofemoral
resists hyperextension and lateral rotation
Medial Plantar Nerve
Arises From
F(x)
arises from: tibial nerve
f(x):
sensory: major sensory nerve to the heel of the foot
motor: abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, first lumbrical
Describe the sural nerve system
Tibial nerve gives rise to the sural nerve; Common fibular nerve gives rise to the lateral sural nerve
Sural communicating branch connects the 2
Lateral Plantar Nerve
f(x)
motor nerve in the foot; innervates all intrinsic muscles in the sole except the muscles supplied by the medial plantar nerve
What muscles are responsible for eversion of the foot?
lateral compartment muscles
fibularis longus
fibularis brevis
Sural Nerve f(x)
skin over the posterolateral leg
Lateral sural cutaneous nerve f(x)
innervates skin over upper lateral leg
