Upper Limb problems Flashcards
What is Carpal tunnel syndrome?
parasthesiae in the median nerve innervated digits - thumb and radial 2 and a half
What can cause carpal tunnel syndrome?
rheumatoid arthritis
diabetes - anything causing fluid retention
pregnancy
weakness of the adductor pollicus brevis
How is carpal tunnel syndrome diagnosed?
Tinnels test - percus the median nerve
Phalens test - hold wrist hyper flexed to reduce space in the carpal tunnel
How is carpal tunnel syndrome managed?
wrist splints at night
carpal tunnel decompression
steroid injections
What is cubital tunnel syndrome?
compression of the ulnar nerve behind the medial epicondyle
What is cubital tunnel syndrome due to?
tight band of fascia forming the roof of the tunnel or due to tightness at the intermuscular septum as the nerve passes through or between the two heads at the origin of the flexor carpi ulnaris
What is the presentation of cubital tunnel?
parasthesiae at the ulnar 1 and a half fingers
Tinnels test positive
Froments test positive
What is the treatment for cubital tunnel syndrome?
surgical release
ulnar nerve decompression
What is the general presentation of frozen shoulder?
gradual onset of pain
gradual decrease of stiffness (over 2-9 months)
What are the signs of frozen shoulder?
loss of external rotation
thickening of the coracohumeral ligament
decrease in joint volume
Who does frozen shoulder affect?
50-60 year olds
diabetics very prone to it
What is the treatment for frozen shoulder?
physiotherapy and analgesia
intraarticular gleno-humeral injections
if no help, manipulation under anaesthetics can help or arthroscopic release
What causes a rotator cuff tear?
degenerative changes in the tendon
trauma
What age group is affected by rotator cuff tears?
> 60 year olds - usually asymptomatic
What are the different types of rotator cuff tears?
partial and full thickness - involve the supraspinatous
large - involves the infraspinateous and the subscapularis
What is the presentation of a rotator cuff tear?
weakness of initiation of abduction - supraspinatous
weakness of internal rotation - subscapularis
weakness of external rotation - infraspinatous
may see some muscle wasting
How is a rotator cuff tear treated?
physio, rest, sling, NSAIDs, analgesia etc..
if no help -> subacromial depression and rotator cuff repair
How is a rotator cuff tear investigated?
MRI
Ultrasound
What is acute calcific tendonitis?
calcium deposits in the supraspinatous tendon cause severe shoulder pain
How is acute calcific tendonitis diagnosed?
Xray - seen proximal to the greater tubersity
How is acute calcific tendonitis treated?
subacromial steroid injections and local anaesthetic injections
pain goes away as calcium reabsorbs
What is shoulder instabitlity?
painful abnormal translational movement, subluxation and/or recurrent dislocation
younger they are - more likely to reoccur
What age group does shoulder instability affect? males or females?
20-30year olds
females
sporty
What is more common: anterior or posterior shoulder dislocation?
anterior due to trauma
