hip and spine plus knee and ankle osteology Flashcards
phases of fracture healing
haematoma
tissue death
inflammation/cellular proliferation
angiogeesis/granulation tissue/procallus
consolidation/hard callus
bony remodelling
t1 vs t2
t1- fluid dark, fat white
t2- fluid white, fat whiteq
where do spinal nerves exit
c1-c7- above
c8- between c7 and t1
t1-l5 below corresponding vertebrae
s1-s4 via sacral formaina
pre axial borders
cephalic vein, long saphenous vein
post axial border
basilic vein, short saphenous vein
structure of IV disc
inner nucleus pulposus (type 2 collagen) outer nuculus fibrosus (type 1 collagen)
role ALL vs PLL
ALL- hyperextension
PLL- hyperflexion
4 stages slipped disc
disc degenration, prolapse, extrusion, sequesteratopm
l4, l5, s1 sciatica
l4- anterior thigh, anterior knee, medial leg
l5- lateral thigh, lateral leg, dorsum foot
s1- posterior thigh, posteripr leg, sole of foot
red flag caudia equina
bilateral sciatica, perianal numbness, painless retention urine, urinary incontenence, ED
3 bones hip joint
ilium, ischium, pubis
what strengthens hip joint
labrum and transverse acetabular ligament, joint capsule, joint ligaments (iliofemoral. pubofemoral, ischiofemoral)
hip flexion
FEMORAL- iliopsoas, rectus femoris, sartorius, pectineus
hip adductor
OBTURATOR adductor magnus, breis, longus (pectineus, gracilis, obturator internus)
hip extensor
SCIATIC - semimembranus, semitendinosus, biceps femoris long head
INFERIOR GLUTEAL- gluteus maximus
hip abductor
SUPERIOR GLUTEAL- gluteus medius and minimus, tensor fascia lata and sartorius (femoral)
muscles in gluteal region and role
Piriformis = Nerve to Piriformis
Gemellus Superior = Nerve to Obturator internus
Obturator Internus = Nerve to Obturator Internus
Gemellus Inferior = Nerve to Quadratus Femoris
Quadratus Femoris = Nerve to Quadratus Femoris
lateral rotation thigh, abduction thigh
