serve re reinforce the articular capsule
what four ligament to contribute the general stability of the knee
ACL
PCL
MCL

how do we hurt the ACL
NC: plant and twist
C: femur posterior blow, severe knee hyperextension
whta is the best test for ACL issue
lachman’s
how is the PCL injuryed
when the supeior portion of the tibia is struck when the knee is flexed
MVA with dashboard
when do we often see a MCL injury
lateral blow to the knee
when do we see LCL injury to the knee
medial blow to the knee
the patella sits where
the trochlear groove of the femur
what movement does the ACL prevent
ant tibia translation on the femur
what are the three fat pads of the knee
quariceps
infrapatella (Hoffa’s fat pad)
prefemoral
what attaches to the Pes anserine
STG
pilcae cause what location of knee pain
anterior knee pain
what movement does the PCL prevent
posterior displacement of the tibia on the femur
what is the OPP for the talocural joint
10-deg of PF
mid way inversion and eversion
what is the CPP for the talocural joint
max DF
what is the capsular pattern for the talocural joint
PF > DF
what is the movement we see at the subtalar joint
inversion and eversion
what is the CPP for the subtalar joint
supination
what is the OPP for the subtalar joint
mid way
where is the sinus tarsi found
between the sup calcanues and inferior talus
it is often associated with inversion injuries
how many vert are in the c-spine
7
what is another namr for C1
atlanto
Atlonto-occiptial joint - movement
permits flexion and ext of the cranium
yes, nodding motion
Atlontoaxial joint - movement
no - mostly
flexion, extension, lateral flexion, and rot
intervertbral joints
sup and inf surfaces of the vert bodies and are associated by intervertebral discs
zygapophyseal joints
formed by the
right and left superior articular factes of one vert
+
right and left inf superior vert
alar ligaments attachment
den to the condyles of the occiput
what does the alar ligament resist
flexion
contralateral side bending
contralateral rot
ant long lig location
reinforces the ant intervert joint
ant long lig reistance
resists extension
what is the CPP for the c-spine
full ext
what is the OPP for the c-spine
midway flex and ext
what is capsular pattern for the c-spine
lateral flex and rot are equally limited
what nerve root s does the brachial plexus arrise from
C5 to t1
what muscle do the nerves that arrise from the brachial plexus serve
the entire upper quarter
what are the two part of the intervert discs
nucleus polposus
annular fibrosis
what are the characterisitics of the NP
gel like substance
what are the characteristics of the AF - disc
attach adj vert and provide strength to disc during c-spine movement
what is the ligament flavum
connects lamina to lamina
what is the function of the ligament flavum
limit flex and rot a of the c-spine
what is the ligament nuchae - function
restricts flexion in the cervical spine
what is the function of the post long lig
restricts flexion in the c-spine
what are uncovertebral joints - other names
uncinate process
Joints of luschka
what are uncovertebral joints
the joints that are formed between the lateral projection on the inferior surfaces of one vert and the lateral projections of the sup surface of another vert
where are uncovertebral joints found
C3-T1
what is the function of uncovertebral joints
guide motion in the sagittal plane and limit motion in the other two planes
what are schordles nodes
prolaspe of the nuclear material into the vert body
tyoe of spinal disc hernaition
what kind of forces are most damaging to the disc
shearing and torsional forces
what is the iliolumbar ligament for
reinforcement for the L/S junction
limits all motion between L1 and S5
- counteract shearing forces at this region
where does the iliofemoral log arrise from
the tip of the L5 TP
what isthe full name for the lats
latissumus dorsi
what do the lats blend with
the thoracolumbar fascia
what are the two muscle that make up the erector spinea
iliocostalis
longissumus
what is the anterior sacroiliac lig
connects the ant surface of the illium to the anterior sacrumm
weakest of the lig
what is the CPP for the lumbar spine
ext
what is the OPP for the lumbar spine
midway between flexion and extension
what are the function of interspinous ligamant
limit flexion and rot of the spine
where do spinal nerve exit in the spine
intervertbral foramin
what forms the lumbar plexus - roots
T12, L1-L4
what muscle does the lumbar plexus innverate
anterior thigh
medial muscle of the thigh
what are the more important branches of the lumbar plexus
obturator and the femoral nerves
how many ribs are there
12
where do the rib art
1-10: costoverbral and costotransverse joints
what are the two floating ribs
11 and 12
what is the scaral plexus made of
S1-S3 and the descending portion of S4
what muscles does the sacral plexus supply
buttock
sciatic nerve - post thigh and lower leg
what are the nerve roots of the sciatic nerve
L4, L5, S1, S2, and S3
what does the sacrospinous lig connect
spine of the ischium to the lateral sacrum and coccyx
what is the function of the sacrospinous lig
prevent anterior rotation of the sacrum on the pelvis
sacraltuberous helps with as well
what part of the pelvis does the sacrum attach to
illium
what seperation does the thoracolumbar fasica form
seperated the lumbar muscles into three parts
to provide stability to the spine
