  1. Treating Fractures Medical Environmental Research Learning INstitute

  2. Goals • Proper triage • Prognosis and repair options for various fractures • Post-op care and protocols • Audience • Rehabbers\first responders • Veterinarians who are interested in doing orthopedics Medical Environmental Research Learning INstitute

  3. Why bother? • We are generally dealing with healthy birds • Prognosis can be quite good • Recovery can be very dramatic Medical Environmental Research Learning INstitute

  4. Factors affecting prognosis • Bone exposure • Proximity to a joint • Chronicity – is the patient emaciated? Our patients have to be close to perfect for a successful outcome. Medical Environmental Research Learning INstitute

  5. Immediate needs\goals • Stabilize the bird • Immobilize bones • Prevent desiccation • Prevent further stress and injury Medical Environmental Research Learning INstitute

  6. Stabilization • Most fractures are not immediately fatal, but shock and stress are. • Warm fluids SQ\IO BID\TID • Pain control with meloxicam and butorphanol • Start antibiotics if open fracture or if surgery will be needed • Baytril 25 1 ml\kg SQ with fluids once, then 15 mg\kg SQ\PO BID (NOT IM) Medical Environmental Research Learning INstitute

  7. Wound care • Clean the wound. Always wear exam gloves when cleaning wounds • Have a lot of flush ready…you will need it Medical Environmental Research Learning INstitute

  8. Irrigation • Warm NaCl or LRS is always best • H2O2 should never be used • For dirty wounds, can use dilute betadine solution Medical Environmental Research Learning INstitute

  9. Debridement • Very painful and very stressful • Very little can or should be done without anesthesia Medical Environmental Research Learning INstitute

  10. Bone exposure • Must prevent desiccation by covering with skin, if possible. THIS IS AN EMERGENCY • Can use temporary sutures if necessary • Can also use collagen\gel dressings • Cover with Silvidine cream and saline-soaked Telfa non-adherent dressing • Start systemic antibiotic (Baytril is my first choice) • Surgery ASAP Medical Environmental Research Learning INstitute

  11. Stabilization • Figure 8 bandage for ulna\radius\metacarpal fractures • Figure 8 + body wrap for humerus and coracoid fractures • Padded splint +\- ball wrap for fractures distal to the knee • Not much can be done for femur fractures. Surgery indicated ASAP. Medical Environmental Research Learning INstitute

  15. A few more points • Examine entire bird including eyes. • Don’t want to put a bird thru surgery if they are NR anyway • If surgery is necessary, do it quickly. • Ideally within 2-3 days of admission Medical Environmental Research Learning INstitute

  16. Ulna fracture • Probably most common fracture • Usually a closed fracture • If alignment ok, figure-8 bandage may be enough • Or an intermedullary (IM) pin placed from the elbow Medical Environmental Research Learning INstitute

  17. Ulna fracture – post-op Goal is to • Prevent callus from bridging to the radius • Provide reasonable alignment Medical Environmental Research Learning INstitute

  18. Ulna fracture Medical Environmental Research Learning INstitute

  19. Ulna fracture - closeup Medical Environmental Research Learning INstitute

  20. Ulna fracture – 4 weeks later Pull pin when • fracture is stable on palpation and • there is radiographic evidence of a mature callus. Medical Environmental Research Learning INstitute

  21. Ulna\radius combo fractures • Almost always open with massive soft tissue trauma • Very difficult to splint. Needs surgery immediately. Medical Environmental Research Learning INstitute

  22. Ulna\radius combo – post-op • IM pin in ulna • IM pin sometimes placed in radius but this can interfere with the wrist joint • Radius normally heals well if ulna is stabilized Medical Environmental Research Learning INstitute

  23. Extremely comminuted Medical Environmental Research Learning INstitute

  24. 5 weeks later Medical Environmental Research Learning INstitute

  25. Don’t rush into surgery Medical Environmental Research Learning INstitute

  30. Humerus fractures • Very variable. • Midshaft, distal, proximal • Transverse, oblique • Comminuted or simple • Can have severe soft tissue trauma. • Severe muscle contracture common. • Bone exposure VERY common • Immediate stabilization requires a figure-8 wrap + body wrap. Medical Environmental Research Learning INstitute

  31. Long oblique, midshaft\distal Medical Environmental Research Learning INstitute

  32. Long oblique, midshaft • Cerclage wires allowed for a very stable fixation Medical Environmental Research Learning INstitute

  33. Transverse, midshaft, comminuted Medical Environmental Research Learning INstitute

  34. Transverse, midshaft • Massive soft-tissue swelling distal to the fracture is poor prognostic indicator • IM pin + external fixator tie-in Medical Environmental Research Learning INstitute

  35. External fixator configurations Medical Environmental Research Learning INstitute

  40. External fixator tie-in • Disadvantages • Technically more challenging. Placing pins can cause damage. • Increased surgical time • More pin tracts to take care of • Very difficult\impossible in small birds? • Advantages • Fixation is MUCH more rigid • Can remove wrap sooner ( 1 week vs 5 weeks). • Definitely the treatment of choice Medical Environmental Research Learning INstitute

  47. Metacarpal fracture • Figure-8 wrap can work. • Seem to take a long time to heal • May attempt IM pin +\- external fixator in large bird Medical Environmental Research Learning INstitute

  48. Coracoid fracture • COHA window strikes • Very difficult to palpate • Surgery is NOT indicated • Treat with figure-8 + body wrap for 2 weeks with intermittant PT. • Prognosis is good Medical Environmental Research Learning INstitute
