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
importance piriformis
divides gluteal region into superior and inferior part, the sciatic nerve enters inferior to piriformis
blood supply hip
deep femoral giving off medial circumflex and lateral circumflex.
blood supply femoral head
artery of ligamentum teres to head in child
in adult- ascending cervical branches giving off medial and lateral circumflex branches
radiology osteoathritis
Loss of joint space. Osteophytes.
Subchondral sclerosis
hip shortened and internally rotated in posterior dislocation
shortened- gluteus maximus, hamstrings and adductors
internally rotated- anterior gluteus medius and minimus
presentation anterior dislocation
externally rotated, abducted, flexed
draw cutaneous nerve distribution in hand
