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

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

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

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

osgood schaltter disease

A

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

Q

associated damage with shoulder dislocation anterior

A

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
Q

presentation of anterior dislocation of shoulder

A

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
Q

what test can do to see if patient has shoulder instability

A

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
Q

investigations shoulder dislocation

A

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
Q

acute managment of shouder dislocaition

A

analgesia, m relxants, sedation - if appropriate
gas and air- entonox
braod arm sling
closed reduction- after excluding fractures
post reduction xray
immobilisation for bit after relocation

193
Q

ongoing managment for shoulder dislocation

A

have increased risk of recurrent dislocation esp if younger
physio- inc movement and reduce risk recur
shoulder stabalisation surgery-
correct underlying strucutral issues:
repair bankart lesions
tighten capsule
bone graft - caracoid process to correct injury rto glenoid= laatarjet procedure
correct hills-sachs lesion= remplissace procedure

long recovery- 3 months

194
Q

frozen shoulder

A

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

Q

types of frozen shoulder

A

primary= occur spontaneously
seondary= occurs in response to trauma/ surgery/ immobilisation

196
Q

presentation frozen shoulder

A

3 phases
painful phase: shoulder pain first sy,tpkms - can be worse at night

stiff phase: shoulder becomes stiff, affected in passive and active movement
external rotation most affected
pain settles during this phase

thawing phase- gets less stiff

can last 1-3 years but some never resolves

197
Q

what movement is most affected in frozen shoulder

A

external rotation

198
Q

Q

carpal tunnel syndrome

A

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
Q

risk factors for carpal tunnel syndrome

A

diabetes
acromegaly
hypothyroidism
rheumatoid arthritis

253
Q

dupuytrens contracture

A

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
Q

presentation of dupuytrens contracture

A

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

257
Q

managment of dupuytrens contracture

A

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

male
manual labour- esp vibrating tools

259
Q

man who has epilepsy and uses vibrating tools cant extend his left ring finger.

A

could be trigger finger but more liekly dupuytrens contracture as rf for it and cant at all extend it

260
Q

trigger finger

A

stenosing tenosynovitis
pain and difficulty moving the affected finger

261
Q

casue and pathophysiology of trigger finger

A

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
Q

presnetation trigger finger

A

pain and tender on mcp joint on palmar side usually there
stiffness
locking / finger stuck in flexed psotion
suddenly realses with painful clicl/pop

303
Q

what blood supplly has the ehad of femur

A

retrograde blood supply from medial and lateral circumflex arteries from femoral arterites. they join at the femoral neck proximal to the intertrochanteric lone

304
Q

what important about where the fracture occurs of the femur

A

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
Q

whats an intracapsualar fractur of femur

A

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
Q

intracapsular fracture which grades may only need internal fixation of head
and which may need remobal and replacement of femoral head

A

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
Q

treatment for intracaspualr fractures of femur

A

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
Q

qhats an extracapsular fracture of hip and types

A

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
Q

presentation of hip fracutre

A

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
Q

investigations for hip fracture

A

xray inital - ap and lateral :
shentons line if distrupted then sign of neck of femur fracture
mri/ct if xray neg but suspect fracture still

311
Q

risk facotrs hip fracutre

A

female
osteoporosis
increasing age

312
Q

management of hip fractures

A

anaglesia
vte asssesment _> enoxaparin
pre op asess- bloods and ecg
orthogeriatrics
surgery same day or day after-> have surgery within 48 hrs of admitted as high mortality
want to weight bear straight away after op and have physio and anaglesia so can mobilise
