1
Q
whats compartment syndrome
A
pressure within a fascial compartment is abnormally rasied cutting off blood supply to the contents of the compartment
2
Q
whats in a fascial compartment
A
msucles
nerves
blood vesles
surrounded by fascia- un able to stretch expand
3
Q
casues of acute compartment syndrome
A
usally due to an acute injury
get bleeding/ swelling (oedema) associated with the injury casuing increase in pressure
eg.
crush injury
bone fractures
4
Q
presentation of acute compartment syndrome
A
most commonly in one of the compartments in legs but can be feet, thighs, buttcls , forearm
pain- disproportionate to the injury- pain meds dont help. main worse on passively stretching hte muscle
paraestheisa - pins and needles
pale
presure- high
paralysis- later and worrying feature
normally can feel the pulses - if not then probs more liekly acute limb ischemia
5
Q
differnetial for acute compartment syndrome if cant feel pulse
A
acute limb ischemia
6
Q
investigation of acute compartment syndrome
A
needle manometry - measure resitance of saline injected into compartment
usually dx is clinical
7
Q
inital managemtn of acute compartment syndrome
A
escalate to reg/consultant orthopedic
remove external bandages/ dressings
elevate to level with heart if leg
maiantain good bp- avoid hypotension
8
Q
definitive managemnt of acute compartment syndrome
A
emergency fasciotomy
- within 6hrs ideally
need to open up the compartment all the way and explore and debride any necrotic tisssue. leave wound open and then re op a few days a;ater can have many to keep debriding necrotic tissue and then eventually can cover the wound opnce swelling reduced. may need skin graf to close eventually
9
Q
whats chronic compartment syndrome
A
also called chronic exertional compartment syndrome
not an emergency unlike acute
10
Q
casues of chronic comparmtent syndrome
A
usually asscoaited with exertion
during exertion pressure in compartment increases and blood flow becomes restircted so symtooms start
when rest the pressure relives and so symtpoms start to resolve
11
Q
symtpoms of chronic compartment syndrome
A
isolated to specific location at the affected compartment
pain
worse on exertion
relives by rest quickly
numbness/ paraestheisa
12
Q
investigation and management for chronic compartment syndrome
A
needle manometry
measure p before during and after exertion
treat- fasciotomy - but not emergency
13
Q
whats osteomyelitits
A
inflammation of bone and bone marrow usually casued by bacterial infection
can be acute or chronic
can have recurrent/ chronic infections after rx for acute
14
Q
casues of osteomyelitits
A
usually bacterial- staphylcoccus aureus most common
15
Q
modes of infection for osteomyeleitis
A
haematogenous osteomyleitits- spread through blood and seeds in bone = most common mode of infection
direct contamination of bone- fracture site/ ortho op
16
Q
risk factors for osteomyeltitis
A
orthopedic surgery- esp prosthetic and esp revision surgery of prostehtic joints (hence give perioperative prophylactic abx for joint replacemnt)
diabetes - esp with diabetic foot ulcers
peripheral arterial disease
iv drug use
immunosupression
open fractures
17

fever
tender/bone pain
swelling
erythenma
generalsied infection:
nasuea and vomiting, lethargy, muscle aches
18
Q
investigations for osteomyelitits
A
mri best for dx
xray can be donw but may not show changes- if no changesshown doesnt mean dont have it- cant use xray to exclude osteomyelitits
bloods- rasied crp, wbc, esr
blood culture may be psotive
bone cultures to find casue and anx senstivities
19

periosteal rxn= changes to bone surface
locaslied osteopenia- thinning of bone
destruction of bone area
20

osgood schaltter disease
caused by inflammation at tibial tuberosity and avulsion fractures occur
inflamamtion at the tibial tuberosity where the patella ligament/tendo, insert.
have multiple minor avulsion fractures occur where the patella ligament pulls away tiny pieces of bone.
so you get growth at tibial tuberisity and so get lump and tender duet o inflammation

say if need xray after acute knee injury if any presetn:
55 and over
patella tenderness and no where else
fibular tenderness
cant felx knee to 90 degress
cant weight bear- cant do 4 steps- limping counts
175
managment for mensical tear
urgernt referal if acute onset knee pain
a and e
fracture clinic
varies
conservative- rice
nsaids= frisrt line analgesia
physio
surgery- arthroscopy- repair/ resection affected part often reusts in OA
176
what casues instability to knee
injury to acl
pcl
meniscus
177
which acl or pcl injury more common
ACL
178
acl attaches where and fucntion
acl attach from lateral aspect intercondylar notch to anterior intercondylar area on tibia
stops tibia moving forward inrelation to femur
179
pcl attaches where and function
pcl medial aspect intercondylar nothc to posterior interocndylar area of tibia
stops tibia sliding backwards in relation to femur
180
presentation acl injury
typically twisting motion
pain
swelling
pop sound/sensation
insability
tibia moves anteriorly
knee can buckle- lack of confience wlaking- msucles weaknes- more injury likely to occur
181
tests for acl injury
anterior draw test- psotiove if feel no clear end point to tibia moving forward
lachman test- same anteiro draw but knee at 20-30 degrees
182
investigations acl injury

whats most common shoulder dislocation and cause
anterior dislocation
as if catching a big rock with arm abducted and extended and then forced backward
humerus head moves anteriorly
187
casues of posterior shoulder dislocation
seizures
electric shock
188
associated damage with shoulder dislocation anterior
bankart lesions = tears to the anterior portion of the labrum
occur with repead subluxation/dislocation
hill sachs lesion= compression fracture on posterolateral head of humerus
as the humerus head dislocates forward the head impacts with the anterior rim of the glenoid cavity
=> makes the shoulder les stable and risk further dislocations
axiallry nerve damage- c5 and c6
= loss sensation on regimental patch of deltoid and weakness of deltoid and teres minor
fractures:
clavicle, humerus head, greater tuberosirty of humerus, acromion of scapula
rotator cuff tears
- esp in older peopl
189
presentation of anterior dislocation of shoulder
acute pai
occur after acute injury
muscles go into spasm and tighten shortly after
deltoid appears flatter and buldge of humerus head anterioly
asses for:
fractures
vascualr damage- absent pulses, prolonged cap refil time, pallor
nerve damage- loss sensation deltoidon regimental patch
190
what test can do to see if patient has shoulder instability
apprehension test
supine
abduct arm 90
flex at elbow 90
then slwly externally rotate and pt will become worrued it will dislocate- no pain just apprehension
191
investigations shoulder dislocation
xray= confrim dx and asses for fractures
not always needed do before relocation but do after to cehck in right place and no fractres
magnetic resonance arthrogrpahy= mri with cintrast injected into shoulder to asses for shoulder damage-> bankart lesions/ hill-sachs lesion
192
acute managment of shouder dislocaition
analgesia, m relxants, sedation - if appropriate
gas and air- entonox
braod arm sling
closed reduction- after excluding fractures

correct hills-sachs lesion= remplissace procedure
long recovery- 3 months
194
frozen shoulder
common cause of shoulder pain and stiffness
also called adhesive capsulitis
loss of range of motion and function in shoulder joint
inflammation and fibrosis in joint capsule leads to adhesions=> bind to the capsule and cause it to tighten aorund the joint
195
types of frozen shoulder
primary= occur spontaneously
seondary= occurs in response to trauma/ surgery/ immobilisation
196
presentation frozen shoulder
3 phases

carpal tunnel syndrome
asued by compression of the median nerve as it goes through the carpal tunnel
casues pain and numbness of the median n distribution
flexor retinaculum = fibrous band over wrist
palmar digital cutanoues branch of median nerve goes through carpal tunnel = supplys innervation of sensory to palmar aspects of full finger tips of thumb, index, middle and lateral half of ring finger
palmar cutanoues bracnh of median nerve supplies palm sensory bu this goes over the flexor retinaculum so palm not affected
median nerve supplies: thenar muscle of hand:
abductor pollicis brevis, oppnens pollicis, flexor pollicis brevis
adductor pollicis is innervated by ulnar nerve
compression of the contents of the carpal tunnel which results in the syndrome is either due to swelliung of contetnseg. tendon due to repptivie strain or narrowing of the sheat
248
risk factors for carpal tunnel syndrome
diabetes
acromegaly
hypothyroidism
rheumatoid arthritis
fam hist
repetivie strain
obesity
perimenopause
most cases are idiopathic but if they have ct syndrome esp bilateral then look for other features of these risk factors
249
acromegaly is a risk facotr for what
carpa tunnel syndrome
250
presentation of carpal tunnel syndrome

numbness
pain
paraestheisa
burning
motor:
thenar muscles
weakness of grip strenth
weakenss of thumb movements (adduction spared as this ulnar nerve)
muscle wasting of thenar
difficult to do fine movements with thrumb
251
tests for carpal tunnel syndrome
tinnels test- tap on middle of wrist - get symptoms sensory postigve
phalens test- flex wrists together and get snesory symtpoms postive
carpal tunnel questionarie- if high risk of having ct then may not need do nerve conudciton
primary investigation is nerve conduction studies- see how well signals pass through median nerve
252
managment of carpal tunnel syndrome
rest and adapt activities
split to hold in neutral position at night for min 4 weeks
steroid injectuins
surgery- la and can be open or laparoscopuc - cut flexor retinaculum to relive pressure on median nerve
253
dupuytrens contracture
fascia of the palm becomes thickend and tight leading to finger contrcture
contracture= shortening of soft tissue
finger gets tighthend into a flexed postion and cant fully exend it
the palmar fascia is strong ct
this becomes thick and tigher and develops noduels and the cords of dnese ct can extend into the finger which pulls the finger into flexed
254
presentation of dupuytrens contracture
frisst present with hard nodules on palm
skin thickening and pitting
fascia becomes thickened and gradually the finger is pulled int flexion
eventually impossible to fully extend the finger
can feel a thick nodular cord on the palm to the finger affected
usually no pain
affects fucntion of hand
255
figner most affected in dupuytrens contracture
ring finger mosy
index finger least afected
256
test for dupuytrens contracture
table top test
if they cant flatten their hands fully onto the table then suggest got it
257
managment of dupuytrens contracture
conservative- do nothging
surgical:
needle fasciotomy - needle in and seperate the cords and loosen them
limited fasciectomy- remove the fascia affected and cord
dermofasciaectomy- remove skin assciated and the abnormal fasci anf then need a skin graft
258
risk facotrs for dupuytrens contracture
smoking and alcohol
epilepsy
diabetes esp T1
age
fam hist- autosomal dominant pattern
male
manual labour- esp vibrating tools
259
man who has epilepsy and uses vibrating tools cant extend his left ring finger.
could be trigger finger but more liekly dupuytrens contracture as rf for it and cant at all extend it
260
trigger finger
stenosing tenosynovitis
pain and difficulty moving the affected finger
261
casue and pathophysiology of trigger finger
flexor tendons pass through ltos of tendon sheaths along the finger
have thickening of the tendon/narrowing of the sheath (tighetning)
then this prevents the flexor tendons from running smoothly through the fliger when flexed and extended
msot common sheath affectedis ths the first annular pulley A1 at the MCP joint
can have a nodule in the tendon stopping it going through sheath
flexed the nodule is outside the A1 pulley but then as you extend the figner the nodule cant go thrugh and gets stuck at the entracne to the A1pulley and so the finger locks and gets stuck in the bent postion
262
presnetation trigger finger
pain and tender on mcp joint on palmar side usually there
stiffness
locking / finger stuck in flexed psotion
suddenly realses with painful clicl/pop
deosnt move smoothly on flexion and extention

303
what blood supplly has the ehad of femur
retrograde blood supply from medial and lateral circumflex arteries from femoral arterites. they join at the femoral neck proximal to the intertrochanteric lone
304
what important about where the fracture occurs of the femur
if intracapsualr fracture then blood supply may be affected by damage of bv if the bone is displaced especially. this can then lead to avascualr necrosis
extracapsular fractures of the femur arnt an issue this way as blood supply remains intact
305
whats an intracapsualar fractur of femur
fracture inside the capsule- proximal to the intertrochanteric line
garden classification:
grade 1= incomplete fracture and non displaced
grade 2= complete fracture and non displaced
grade 3= partially displaced- trabeculae at angle
grade 4= fully displaced - trabeculae parralele
306
intracapsular fracture which grades may only need internal fixation of head
and which may need remobal and replacement of femoral head
grade 1 and 2 the blood supply may not be affected as not displaced so may have intact blood supply. if this the case then internal fixation may only be needed
grade 3 and 4 where displacemnt has occured will need remvoal and replacement of femoral head as the blood supply will be damaged and so avascualr necrosis of the femoral head will have occured
307
treatment for intracaspualr fractures of femur
if non displaced grade 1 and 2 then may only need internal fixation eg. with screws if the bv arnt damaged
grade 3 and 4 where they are displaced will need removal of femoral head and replacemnt :
hemiarthroplasty= only remove and replace head
or
total hip replacement = head and acetabulum (do if fit and mobile before surgery before fracutre obvs)
308
qhats an extracapsular fracture of hip and types
fracture occur distal to intertrochanteric line = bood supply of head not affected = head doesnt need replacing
intertrochanteric fractures:
between greater and lesser trochanter
treat with dynamic hi[p screw- adds some cntrolled compression across fracture so improve healing (bones need weight bearing stuff to make them grow eetc)
subtrochanteric fracture:
distal to lesser trochanter- no more than 5cm below
[roximal to shaft of femur fracture
treat:
intrameduallry nail
309
presentation of hip fracutre
pain- groin, buttocks can radiate to knee
esp older pt fallen
SHORTENED ABDUCTED AND EXTERNALLY ROTATED LEG
look for any underlying illness that cuased it:
anemia
mi
arrythmia
stroke
electroylte imbalance
heart failure
urinary / chest infections
310
investigations for hip fracture
