Q

Describe the S/Sx for CTS

A
  • compression of med nerve > reduced blood flow > edema > ischemia to the nerve
  • paresthesia median nerve distribution
  • reduced grip strength
  • abductor poll brev wasting (usually in older people who’ve ignored it for awhile)

Q

Describe the pathophysiology of DeQuervains

A
  • repetitive gliding from mm use in the first dorsal compartment causes shear trauma
  • non inflammatory process
  • thickened retinaculum, narrowed canal so imparied gliding of tendons in the canal

Q

Mx for DeQuervains

A
  • thermoplastic splint for 6 weeks - then start strengthening + replace with neoprene splint
  • ice
  • avoid agg activities (pulling up the sheets is characteristically painful!)
  • radial nerve glides if needed
  • gentle ROM ex
  • steroid injection might be needed if not improving- cures 83% of cases
  • surgery = longitudinal release of the tendon

Q

Post op rehab of distal radial fracture (ORIF)

A
  • RICE
  • thermoplastic resting splint over a tubifast sleeve with padded straps with DPC and thenar eminence free
  • Scar care
  • ROM ex + tendon gliding ex as well
    (ROM eg. table top, hook fist for FDS/FDP, wrist ext/flex, supin/pron)
  • begin strengthening at 6-8 weeks

Q

Describe scaphoid fracture

A

FOOSH injury
px in snuffbox
XR might be negative for 10days to 2 weeks so treat as if they do have a fracture
Can do bone scan at 48 hrs (15% false +ve)

Q

What are indications for conservative treatment for scaphoid fractures?

A

stable, undisplaced waist #
- this take 6-12 weeks to heal with 60-90% union)
tubercle fractures
- (wrist splint 3-4 weeks)

Q

What are indications for surgical treatment for scaphoid?

A
  • unstable displaced fracture
  • fracture/dislocation
  • proximal pole fracture
  • non union
  • pathological fracture
  • carpal instability
  • ORIF = quicker RTW/RTS

Q

What is post op Mx for scaphoid #?

A
  • immob for 7-10 days
  • gently unresisted ROM ex - splint between ex sessions
  • avoid contact sports until healing/union confirmed with XR - can be 3 months
  • most regain good motino with simple home program
17
Q

Describe the scaphoid shift test

A
  • apply pressure AP to the scaphoid tubercle with wrist in UD
  • bring wrist into RD passively
  • if there’s SLL laxity then will be able to push the scaphoid back over rim of the radius
  • on release might here a clunk as scaphoid relocates back into lunate fossa
18
Q

What is the ring sign and when do you see it?

A
  • when there is rotation of the scaphoid as seen with scapholunate dissociation, the ring sign appears due to the the foreshortening of the scaphoid
  • also see Terry Thomas sign
19
Q

What is mx for SLL?

A
  • splint 6 weeks
  • exercise in dart throwing motion of wrist (minimizes motino between scaph+lunate)
  • grip strengthening only when pain free
  • progress to proprioception (slosh pipe)
20
Q

Which muscles are good for the SL and which are bad?

A

Good:

  • ECRL
  • APL
  • FCU

Bad:
- ECU

21
Q

What are S/Sx of TFCC injury?

A
  • ulnar wrist pain
  • prominent ulnar styloid (aka supinated carpus)
  • reduced grip strength
  • weak grip/pain in pronation = ulnar impingment or TFCC
22
Q

Describe the TFCC shear test

A
  • stabilize ulna and glide the piso-triquetral complex dorsally
  • +ve if there’s pain
  • sens/spec = 66%
23
Q

Describe the TFCC shear test with compression

A
  • still gliding PT complex AP but adding axial compression and ulnar deviation whilst doing it
24
Q

Describe the Gripping Rotary Impaction test (GRIT test)

A
  • arm by side at 90º flexion
  • measure grip in full sup/full pron/neutral position
  • ratio of supinated grip/pronated grip
  • if > 1 then ulnar impaction syndrome
  • UIS = abutment of the ulnar into the TFCC and ulnar sided carpals which results in degeneration of the TFCC and chondromalacia of the ulna+carpas + disruption of triquetrolunate ligament
25
Q

What is the management for TFCC injury (conservative?)

A
  • might need to support ulnar carpals for 4-6 months
  • activity mod - avoid loading ulnar side
  • PQ strengthening
  • grip strengthening in pain free ranges of wrist rotation
26
Q

What is the presetnation of TMC OA? (OA of the first MCPJ)

A
  • painful, achy, locally tender
  • joint thickening
  • deformity with subluxation at base of 1st MC
27
Q

What is the TM grind test?

A

Stabilise the trapezium and axially load and rotate the metacarpal

28
Q

Describe self management for CMC OA

A
  • Education (proper alignment, better work methods to reduce joint stress)
  • Aids to help with ADLs without causing pain
  • Cryotherapy/heat therapy
  • Massage
  • Preserving PROM of CMC joint - web stretch/trigger point/self traction
  • Weight loss (OA and obesity has inflamm link)
29
Q

What are other options for treating CMC OA besides self management?

A
  1. Splinting
  2. Exercise (proprio/neuromm/strength)
  3. Neural glides
30
Q

What predisposes one to CMC OA?

A
  1. Genetics
  2. Joint incongruity
  3. Thumb ligament insufficiency
  4. Poor neuromm control of joint
