Regional Periarticular Pain Flashcards
(97 cards)
what is de quervains tenovaginitis
Painful inflammation of the abductor pollicis longus and extensor pollicis brevis in the first dorsal compartment in the wrist (proximal to the snuff box)
how does de quervains tenovaginitis present
Acute pain/tenderness in 1st dorsal compartment of thumb on use +/- swelling
Most commonly on unaccustomed intensive activity (painting fence)
what patients classically have de quervains tenovaginitis
Women
Middle aged
Post partum
what would you find on examination with de quervains tenovaginitis
Looks normal – potentially swelling on radial border
Feels normal – potentially tender over radial border
Active thumb abduction/opposition and active ulnar deviation of the wrist may be affected
Finkelsteins test positive
what test is positive in de quervains tenovaginitis
finklesteins
what are differentials of de quervains tenovaginitis
Base of the thumb OA
OA = joint tender both on palm and dorsally (not found in DQT)
Finkelsteins test +ve indicates DQT is more likely
whats the management of de quervains tenovaginitis
Conservative
Most respond well to rest, analgesia and splintage with thumb immobilization for 3 weeks
Steroid injections may be used
Surgical
Very rarely longtitudinal compartment release may be required if there is recurrence
whats inside the flexor retinaculum
4 flexor digitorum profundus
4 flexor digitorum superficialis
1 flexor pollicis longus
what is carpal tunnel syndrome
median nerve compression
whats the aetiology of carpal tunnel syndrome
Idiopathic – 95%
Diabetes
Rheumatoid Arthritis
Colles fractures (as well as other trauma)
Acromegaly
Hypothyroidism
how does carpal tunnel syndrome present
pain/parastesia in hand - some get numbness or tingling
weakness and wasting of thenar muscles, + sensory loss in palm/radial 3.5 fingers if left unnoticed
what tests are commonly positive in carpal tunnel syndrome
Phalens and tinels
how do you manage carpal tunnel syndrome
Conservative
Rest
Night time splinting
NSAIDS/steroid injections
Surgical
Division of the flexor retinaculum – leads to a scar in the palm
what causes cubital tunnel syndrome
chronic compression of the elbows (computer desk all day)
Tight fascial bands
Ulnar fracture
Valgus deformity of the elbows
Others
how does cubital tunnel syndrome present
Pain near elbow joint, may radiate down ulnar border of the forearm
Paraesthesia and sensory loss in ulnar distribution
Hand clumsiness and reduced pinch/grim strength
Severe = wasting of hypothenar and interosseus muscles leading to hand clawing
what nerve is affected in cubital tunnel syndrome
ulnar nerve
what would you find on examination in cubital tunnel syndrome
Look - ‘guttering’ between metacarpals + hypothenar wasting (only if progressed)
Feel – tenderness over cubital tunnel
Move – elbow movement may be limited and patient may be unable to extend at the interphalageal joints, or actively abduct/adduct affected fingers
Test – reduced first dorsal interosseus power, tinels positive along ulnar nerve, elbow flexion test positive (sustained elbow flexion with arm supination and wrist extension reproduces symptoms)
whats the management of cubital tunnel syndrome
Conservative
Night time splints
NSAIDS
Activity modification
Surgical
Simple cubital tunnel decompression
Anterior transposition of the nerve
what is a ganglion cyst
Soft tissue swellings filled with a degenerative myxotic (mucus-y) fluid stemming from an underlying joint capsule, tendon or sheat
what is the typical patient for a ganglion cyst
woman, aged 20-40
what are common areas for a ganglion cyst
wrist - dorsal or polar
DIPJ
Base of finger from flexor sheath
how does a ganglion cyst feel
can be hard or soft but is never fixed to skin
how do you manage a ganglion cyst
Conservative
Rest + reassurance
30-50% disappear on their own – this may take years though
NSAIDS
Aspiration +/- steroid injection have 40% success rate
Surgical
Excision
40% recurrence rate
what is trigger finger
idiopathic fibrosis of flexor tunnel leading to interruption of the flexor movement usually involving ring/middle finger
finger gets stuck in flexion, with continued effort it may snap into extension
severe cases = finger locked perfectly
