Tibia plateu, shaft, and plafond fractures 2012

  1. 1. TIBIA PLATEU, SHAFT, AND PLAFOND FRACTURES AAOS/ASSH General Review Jul 12, 2012Matthew L. Jimenez, MD, FACS
  2. 2. Mandatory DisclosureÜ  The 2012 14th Annual Chicago Trauma Symposium received support from 40 industry partners
  3. 3. Mandatory DisclosureÜ  Foundation for Education and Musculoskeletal Research (FEMR) several industry and philanthropic partners
  4. 4. Tibia Plateau Fractures
  5. 5. Surgical GoalsÜ  Obtain/Secure Articular ReductionÜ  Reduce Condylar WidthÜ  Restore Axial AlignmentÜ  Neutralize Meta-DiaphysisÜ  Secure Tibial TubercleÜ  Early ROMÜ  Appropriate Soft Tissue Handling
  6. 6. Surgical Timing§  Stage 1: Temporary Spanning External Fixation ú  Soft tissue stabilization ú  Fracture stabilization in polytraumatized patient ú  Develop surgical tactic - CT scan!!!!§  Stage 2: ORIF ú  Execute surgical tactic ú  Definitive articular & axial reductions and fixations
  7. 7. Buttress PlatingButtress plate - A plate employed to support the fractured bone in the area of the metaphysis, usually used in conjunction with lag screwsAntiglide plate - A plate used to reduce an oblique fracture indirectly through interference between the plate and the undisplaced main fragment
  8. 8. ButtressÜ  Resists shear forcesÜ  Metaphyseal Fractures
  9. 9. ButtressFunction

  18. 18. Lateral locked vs dual platingÜ Can bicondylar fx s be treated with laterally based locked plating alone?Ü Is dual incision and plating better?
  19. 19. Lateral locked plating has NOT solved it all

  30. 30. Tibia Shaft Fractures
  31. 31. Current Surgical Indications- Open Fracture- Vascular Injury- Compartment Syndrome- Multi-trauma- Unstable Fracture
  32. 32. What is an Unstable Tibial Shaft Fracture?- 1 cm shortening- Tibia + fibula fractured at samelevel- High-energy fracture- Displaced tibia with intact fibula
  33. 33. Current Concepts: Reamed Intramedullary Nailing- Proximal (4-7 cm fromjoint)- Distal (3-4 cm from joint)- Segmental fractures- Closed fractures- Open fractures
  34. 34. Early Amputation for Mangled Extremity?
  35. 35. Early Amputation for Mangled Extremity? NO
  36. 36. Mangled Extremity: LEAP Study- Scoring systems are not helpful.- Initial sensation is not a reliable indicator offuture sensation.- Results poor at 2 years, whether amputated orsalvaged.- Results even worse at 7 years.- Most risk factors for poor results are beyondsurgeon s control.- Poor results related to socioeconomic status
  37. 37. Damage Control
  38. 38. IM Nailing after Ex Fix?- Best done early (within 2weeks)- Pin sites must be clean.- Patient must be stable.- Infection risk higher than infemur.
  39. 39. ORIF after Ex Fix?- Can be delayed.- Pin sites should be clean.- Skin must be healthy.- Can be minimallyinvasive.
  40. 40. Techniques for Proximal Fractures:- Obtain reduction.- Provisional plating (unicortical).- Blocking screws.- Multiple interlocking screws.- Interest in suprapatellar approach.
  41. 41. Techniques for Distal Fractures:- Plate fibula if fractureddistally.- Steinman pins as joysticks.- Blocking screws.- Multiple interlocking screws
  42. 42. Wire FixatorsBeing replaced by locking plates.
  43. 43. Summary of Current Concepts- Indications have not changed.- Reamed intramedullary nailing is the mainstay oftreatment.- Remember ATLS, Damage Control.- Don t be in a hurry to amputate.- Consider delayed ORIF after Ex Fix.- Obtain and Maintain reduction of proximal anddistal fractures.- New technologies have not yet withstoodscrutiny.
