    • 4000 hours direct practice experience in hand therapy
  2. what are the requirements to become recertified as a certified hand therapist
    • take exam or have 80 hours ceu, 36 of which must be hand/upper extremity related
    • have 2000 hours clinical experience in hand therapy
  3. the certificate to become a hand therapists comes from
    hand certified therapy commission
  4. what are the bones that articulate with the radius
    • scaphoid
    • lunate
    • distal ulna
  5. what does FOOSH stand for
    • fall
    • on
    • out
    • stretched
    • hand

    this occurs more frequently in the wintertime because of ice and snow
  6. true or false – joints with pre-existing but asymptomatic osteoarthritis are very susceptible to stiffness even if not involved in the trauma
  7. true or false – a fall on the outstretched hand may also injure the proximal joints
    • true– elbow and shoulder
    • if the patient has a fractured wrist don't forget to check these joints
  8. what are the three common types of distal radius fractures
    • Colles Fracture
    • Smith's Fracture
    • Barton's displacement
  9. which distal radius fracture is the most common type of fracture
    Colles fracture
  10. what is the mechanism of injury for a Colles Fracture

    • fall on extended wrist and pronated forearm
    • usually falling backwards
  14. what is a Bartons fracture
    • displaced, unstable fracture
    • carpal displacement with the fragment of radius distinguishes this from Colle's and Smith's
  15. what does this picture represent and what kind of fracture is it associated with
    • dinner for deformity
    • Colle's fracture
    • what is seen in the emergency room – we don't see this very much
  16. distal radius fractures objective findings should include
    • observations– atrophy, swelling, deformity, scars, color
    • limited range of motion– wrist, forearm, hand, shoulder
    • weakness– finger extensors stronger
    • sensory status– check for median nerve compromise, complaints of numbness and tingling
  17. what is the treatment for distal radial fractures
    • immobilization – cast or splint it
    • close reduction and cast
    • ORIF - open reduction internal fixation
    • external fixator
  18. what are some observations to consider when looking at distal radius fractures – objective findings
    • atrophy
    • swelling
    • deformity
    • scars
    • color
  19. what is one observation we can make this picture
    right-hand has a mild amount swelling because there are less wrinkles in the hand
  20. what is being measured in this picture
    volume– this is part of objective findings
  21. what are some limitations to be concerned about when looking at distal radius fractures – objective findings
    • range of motion of wrist, forearm, hand, shoulder
    • patients have usually been in a cast and therefore have not used their extensors or flexors
  22. what are some weaknesses that are observed in distal radius fractures– objective findings
    • finger extensors are usually stronger than wrist extensors
    • because the patient has been in cast and has been able to move fingers but not wrist
  23. what are some sensory concerns you should have when considering distal radius fractures – objective findings
    • check median nerve because it is very close to the bones of the forearm, compact space, very common to have swelling and compression in that area.
    • Perform Semmes Weinstein Test
  24. what does this picture represents
    • Semmes Weinsten monofilament test
    • test sensation of the hand
    • used to track the sensation of the handhas the nerve recovers from injury
  25. distal radius fracture management – what is the main goal
    main goal is to have functional range of motion
  26. true or false – it is very rare for a patient to return to full range of motion
    • true
    • if they do they are probably 15 or very young

    • active range of motion of all involved joints
    • joint mobilization techniques
    • home exercise program – active range of motion addressing all involved joints
  30. treatment continued

    true or false – Most treatments for the hand are started with a hot pack, paraffin bath, fluidotherapy, or some kind of
  31. treatment continued

    True or false – for the hand it is preferred that you do active range of motion rather than passive range of motion
    • true
    • when we see the patient the fracture is not strong enough for the hand to withstand passive stretching
  32. treatment continued

    what are the three exercises used for active range of motion in the treatment of distal radius fracture
    • intrinsic stretching
    • tendon gliding
    • isolate wrist extensors
    • the first picture demonstrates a tight intrinsic muscle
    • Flexing the IP joint and the MP joint– they have full range of motion

    • The second picture shows the finger being brought into extension
    • The IP flexion is tight = tight intrinsic muscles

    This is not the same as joint tightness which would mean that the MP joint was tied in flexion and extension
  33. what is tended gliding
    mobilization of the nerves in the upper extremity
  34. Explain this Tendon Glide

    • flexor digitorum superficialis
    • maximum excursion occurs in straight fist position

    • Maximum excursion of FDP occurs in fist position

  36. explain this tendon glide
    • maximum excursion between FDS and FDP occurs in hook position
    • MP extended withPIP and DIP flexed
  37. why are tendon glides so important
    • prevents formation of adhesions after trauma or surgery
    • Forces each digital joint through full potential range
    • Aides tendon and cartilage nutrition
    • valuable in treating inflammatory tendon disorders
  38. true or false – patients with distal radial fractures are often splinted to help reduce median nerve pain
  39. when can you start using weights in the treatment of distal radial fractures
    • after about six weeks – low weights
    • elbow curls
    • supination/pronation
    • wrist curls
    • putty, gripper- must be careful with this because they can overdo it real easy
  40. which motion is most often restricted in the wrist
    • supination – joint mobilization
    • splints are often used to help facilitate supination
  41. carpal tunnel syndrome
  42. what are the anatomical structures associated with carpal tunnel syndrome

    compression of the median nerve in the carpal tunnel
  45. what are the signs and symptoms of carpal tunnel
    • pain in paresthesia, usually worse at night

    • sometimes, edema and/or radiating pain

  46. What does this picture demonstrate
    atrophy in the thenar eminence– right side

  48. what is tinel sign
    tapping on the nerve
  49. what test is this
    • phalen's– hold for 30 to 60 seconds
    • Positive – reproduces parathesias
  50. what is a way to make the median nerve glide
    put hand in supination with passive wrist and finger extension followed by active composite fist, this may be an effective procedure to produce median nerve excursion
  51. what are the goals of carpal tunnel syndrome
    • decrease pain
    • Decrease parathesias
    • Independence in self management - education
  52. how often should tendon gliding performed during the dayin the treatment of carpal tunnel syndrome
    three or four times a day
  53. what are some things that need to be addressed while treating a patient with carpal tunnel syndrome

    • exercise to improve tendon gliding
    • Education positions/activities to avoid
    • Night splint, especially if a phalen's, reverse Phalens are positive
  54. what is the benefit of splinting
    promotes the wrist to be in neutral position, which allows for more space and decreases compression
  55. what kind of treatment is this
    • ASYTM
    • augmented soft tissue mobilization
    • this is good for patient that wants to get better but doesn't want surgery
  56. other than ASYTM what are some other conservative measures for the treatment of carpal tunnel syndrome
    • NSAIDS
    • steroid injections
    • vitamin B6
  57. if all conservative treatments fell for the treatment of carpal tunnel syndrome what is the last resort
