  • Each horse is different
  • New theories every year.
  • Need good laminitic rad
  • Need good laminitic rad
  • Add styrofoam picture
  • clog
  • How do you treat without a diagnosis?
  • Chronic cases are harder to treat
  • Causes
    Conformation
    Shoeing
    Other lamenesses
    Hard ground
    Poor riding
  • video
  • Egg bar or eggbar-heartbar
    Can cover crack with adhesive once infection is cleared up
    Wires and nails rarely needed if foot is balanced properly
  • Need to remove infected tissue and a margin
    May need to do in stages if widespread
    Need a frog support shoe if affects more than 1/3 of hoof
    Problems occur
    If covered too soon - abscess
    Don’t support wall - laminits

    1. 1. Shoeing The Lame Horse MPES OVC Student Seminar Mike Pownall, DVM, CF McKee-Pownall Equine Services www.mpequine.com QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.
    2. 2. 3 Things We Will Learn Today • What are Farrier/Vet Roles? • What are Some Common Foot Lameness? • What are Treatments
    3. 3. Rule # 1 • Vets and Farriers must play well together
    4. 4. Rule # 1 • Vets and Farriers must play well together
    5. 5. Farrier and Vet Roles Need to know what normal is Each horse is different Each Horse is DifferentEach Horse is Different
    6. 6. Farrier and Vet Roles Assessing Balance • Static  leg and hoof while standing • Dynamic  leg and hoof in motion
    7. 7. Static Balance Foot Symmetry - sole
    8. 8. Rule # 2 Not everything is at it appears to be
    9. 9. Static Balance Foot Symmetry - sole
    10. 10. Static Balance Foot Symmetry - coronary band
    11. 11. Static Balance Foot Symmetry - coronary band
    12. 12. Static Balance
    13. 13. Dynamic Balance • How leg and hoof move together • Problems can be due to shoeing, conformation, lameness • Factors to consider  Does the foot land flat  Difference between walk and trot  Difference when ridden?
    14. 14. Dynamic Balance QuickTime™ and a Cinepak decompressor are needed to see this picture. QuickTime™ and a decompressor are needed to see this picture.
    15. 15. Strategy For Shoeing Lame Horses • Know the Lameness • Know the Shoe • Know Team Strengths
    16. 16. Common Lameness's Helped By Horseshoeing • Laminitis/Founder • “Navicular” or Heel Pain • Toe & Quarter Cracks • White Line Disease • Abscesses
    17. 17. Laminitis & Founder • Many treatments • Challenging • Many shoeing techniques with little supporting science • Intensive supportive therapy
    18. 18. Terminology • Laminitis  Inflammation of lamella • Founder  Rotation of P3 from hoof wall • Sinker  Complete detachment of P3 from hoof
    19. 19. What Laminitis Looks Like
    20. 20. What Laminitis Looks Like
    21. 21. What Founder Looks Like
    22. 22. What A Sinker Looks Like
    23. 23. Shoeing The Laminitic Horse • Xray before and during treatment • Re-distribute weight bearing away from hoof wall • Reduce pull of DDFT
    24. 24. Radiography
    25. 25. Radiography
    26. 26. Venograms
    27. 27. Venograms
    28. 28. Venograms
    29. 29. Venograms
    30. 30. Shoeing The Laminitic Horse Stabilize Acute Cases • Minimize further damage • Too painful to shoe • Sometimes all you need • Great with grain overload • Use high density styrofoam or Soft Ride boots
    31. 31. Shoeing The Laminitic Horse Stabilize foot
    32. 32. Shoeing The Laminitic Horse
    33. 33. Shoeing The Laminitic Horse Re-distribute Weight From Hoof Wall • Decrease load on lamellae • Use frog, bars and sole • Utilize area behind true apex of frog • Use radiographs and hoof testers
    34. 34. Shoeing The Laminitic Horse
    35. 35. Shoeing The Laminitic Horse Reduce Pull of DDFT • Decrease tearing forces on laminae • Surgical and shoeing techniques • Tenotomy often essential • Raise heels  Extremely high heels leads to compression of P3 • Facilitate breakover
    36. 36. Shoeing The Laminitic Horse Reduce Pull of DDFT
    37. 37. Shoeing The Laminitic Horse
    38. 38. Shoeing The Laminitic Horse Protect Bottom of Foot Never Place a Permanent Pad on an Acute Case!!!!!
    39. 39. Shoeing The Laminitic Horse Minimize Hoof Wall Trauma
    40. 40. The “Clog” • #6 x 1.25 drywall screws • Adhesive • Casting tape • Soft impression material
    41. 41. Why The “Clog”? • Versatile breakover • Protect sole • Frog support • Minimize hoof wall strain • Decrease strain on DDFT.
    42. 42. The “Clog”
    43. 43. The “Clog”
    44. 44. The “Clog”
    45. 45. The “Clog”
    46. 46. The “Clog”
    47. 47. The “Clog”
    48. 48. Shoeing The Laminitic Horse •Be patient •Pain control •Quality of life
    49. 49. Heel Pain • Navicular? • Crushed and Bruised Heels • Sheared Heels • Thrush
    50. 50. Navicular - Is It Real? • Radiographic lesions are confusing. • Diagnostic blocks are confusing
    51. 51. Shoeing For Navicular • Often need concurrent medical therapy • Access hoof balance and correct that first • Increasing heels will work if DDFT is involved in acute cases • Wedging heels too much will lead to coffin joint problems and crushed heels.
    52. 52. Crushed and Bruised Heels • Long toe - underrun heels • Often misdiagnosed as navicular • Takes a long time to correct • Often need to wait until show season is over
    53. 53. Crushed and Bruised Heels Goals of Therapy • Balance feet • Remove long and damaged heel tubules • Shoes to minimize forces on heels • Place shoes where you want heels to be • Medication to reduce inflammation • Patience
    54. 54. Crushed and Bruised Heels Therapy Remove Long Heel & Toe
    55. 55. Crushed and Bruised Heels Therapy Wedging collapsed heels often counter productive
    56. 56. Sheared Heels • Balance, pain and conformation related • Rarely diagnosed • Very painful • Need to stabilize the foot to stop shearing • Long term therapy
    57. 57. Thrush • Found in  Horses that are inactive and have club feet  Lameness in affected limb  Horses with pads • Lack of blood flow to area bacterial and fungal infection of frog • Penetrates sensitive tissue of sub solar region • Mimics Navicular
    58. 58. Thrush Therapy • Can take a long time to treat • Balance feet • Eliminate other source of lameness. • Animalintex to drain infection • Remove infected tissue • Thrushbuster http://www.mpequine.com/Treat_Thrush.aspx
    59. 59. Quarter Cracks • Caused by medial-lateral imbalance  Wedging up one side  Landing harder on one side • Focal pressure causes hoof wall to break down • Pain caused by shearing of torn hoof wall • Sometimes not noticeable on hoof wall • Coronary band is jammed up at site
    60. 60. Quarter Cracks QuickTime™ and a Cinepak decompressor are needed to see this picture. QuickTime™ and a decompressor are needed to see this picture.
    61. 61. Quarter Cracks QuickTime™ and a Cinepak decompressor are needed to see this picture. QuickTime™ and a decompressor are needed to see this picture.
    62. 62. Quarter Cracks Shoeing
    63. 63. Toe Cracks • Caused by long toes or excess rasping of toes • Set shoe back • Clean out crack • Adhesive or staples once infection cleared  like quarter cracks • Superficial cracks respond to balance
    64. 64. Toe Cracks
    65. 65. White Line Disease • Fungal or bacterial infection of white line • Commonly called “gravel” or “seedy toe” • Often not noticed until it has undermined a lot of hoof wall • Topical therapy is not satisfying due to lack of penetration • Best therapy is hoof wall removal • Often need hoof wall support like a laminitic horse
    66. 66. White Line Disease
    67. 67. Abscess • Minimize digging at sole  Damage from digging is worse than abscess  Drill hole in hoof wall to drain abscess • Soak with Animalintex for 2-3 days • Epson salt traps abscess in hoof  Good once abscess has broken through • Sugardyne or Clean Trax once abscess has begun to drain
    68. 68. Abscess
    69. 69. Shoeing the Lame Horse • Rare to have quick fix! • Interferes with show season • Teamwork • Price • Aftercare concerns!  Turnout  Time involved in treatments
    70. 70. It Can Be Overwhelming
