Deep Fibular Nerve
|
FOOT DROP, paresthesia in webspace between big toe and second toe
|
|
|
Femoral Nerve
|
(from posterior division of L2, L3, L4)
longest branch is saphenous nerve - sensation over area of great saphenous vein; impaired ability to flex at hip and extend knee; decreased patellar reflex |
|
|
Superior Gluteal Nerve
|
(L4, L5, S1 - exits via greater sciatic foramen above piriformis) innervates gluteus medius, minimus and tensor fascia latae; impaired hip abduction , in walking - "Trendlenburg" gait: pelvic tilt (sag) toward opposite side form lesion
|
|
|
Inferior Gluteal Nerve
|
(L5-S2; gluteus maximus - exits greater sciatic foramen below piriformis w/ pudendal and sciatic)
impaired lateral rotation and extension of thigh at hip, DIFFICULTY GETTING UP FROM A CHAIR, gluteus minimus gait = thrust torso posteriorly |
|
|
Superficial Fibular Nerve
|
impaired eversion and dorsal sensation, but extension is intact
|
|
|
Tibial Nerve
|
"tarsal tunnel syndrome" = decreased flexion of big toe, difficulty standing on tiptoe
|
|
|
Obdurator Nerve
|
(L2-4, anterior division, medial thigh-adductors- exits via obdurator canal)
impaired adduction of thigh at hips |
|
|
Terrible triad
|
anterior cruciate ligament
medial collateral ligament medial meniscus |
|
|
Anterior drawer sign
|
tibia displaced anteriorly to femur in flexed knee
indicated ACL tear |
|
|
Sx of torn Medial collateral ligament
|
pain when leg is rotated medially at the knee (abnl passive abduction)
