  3. 3. Answer: Hill-Sachs deformity
  4. 4. Hill Sachs deformity -compression fx of posterolateral humeral head from anterior rim of glenoid -50% of anterior dislocations -may infer damage to cartilagenous and/or osseous portions of the glenoid but does not change mgmt -associated with recurrent dislocations -only requires repair when associated with significant shoulder instability
  5. 5. 79yo F s/p fall from standing, c/o hip pain. Name fracture, be specific
  6. 6. Answer: Intertrochanteric femur fracture
  7. 7. Intertrochanteric hip fracture <ul><li>results from falls, generally in elderly </li></ul><ul><li>Most common hip fx </li></ul><ul><li>leg will be shortened, externally rotated (dislocation will be shortened internally rotated) </li></ul><ul><li>Bucks traction </li></ul><ul><li>admit for ORIF/hemiarthroplasty </li></ul>

  10. 10. Supracondylar fracture -make up 60% of fx of elbow -Type I: non displaced (posterior fat pad, sail sign, radiocapitellar line) - splint, ortho f/u Type II: partial displacement but retains cortical contact; III: posteromedial or posterolateral displacement w/o cortical contact -II and III admit for closed reduction, pin fixation, possible ORIF; -Volkmann's contracture: swelling  incr’d forearm pressure  muscle necrosis, fibrosis, contracture

  12. 12. Answer: Femoral neck fracture; emergent ortho consult
  13. 13. Femoral neck fracture -intracapsular meaning higher risk for vascular compromise due to tearing of vessels or compression by hemarthrosis -admit all for ORIF but need emergent orthopedic consultation if young 2/2 high risk of AVN (w/ older pt they'll just do hemiarthroplasty)

Scaphoid fracture -Scaphoid transmits force from hand to forearm making it most common carpal bone fx (triquetrum=2, lunate=3) -Result from FOOSH or axial load on thumb -TTP over snuffbox - examine with wrist in ulnar deviation, and check for pain w/ axial loading of thumb -negative plain films in 10% - repeat in 2 weeks and splint if high degree of suspicion -non-displaced fx = thumb spica splint and non-emergent ortho referral, if displaced may need ORIF -risk of AVN and non-union if not treated appropriately
  26. 26. 20yo snowboarder c/o L wrist pain s/p fall onto clenched fist.
  27. 27. Answer: Smith’s fracture
  28. 28. Smith’s fracture -aka &quot;reverse Colle’s = fracture of distal radius with VOLAR angulation of distal fragment  &quot;garden spade deformity&quot; -result of fall on flexed wrist -tx same as colles, although volar angulation makes reduction difficult, if angulation not severe/tenting skin, just splint.
  29. 29. 55yo M w/ wrist pain s/p fall. Name the injury and tell-tale sign
  30. 30. Answer: Scapholunate dissociation
  31. 31.

  35. 35. Answer: Trimalleolar fracture
  36. 36. Trimalleolar ankle fracture -Fracture involves lateral malleolus, medial malleolus and posterior aspect of distal tibia (posterior malleolus – misnomer) -If there is asymmetry in gap between the talar dome and 2 malleoli on mortise view, the injury is presumed to be unstable -Emergent ortho consult – may d/c w/ early o/p f/u if able to tolerate crutches

  47. 47. Answer: Salter-Harris II
  48. 48. Salter-Harris II fracture -SH classication used to classify fractures involving epiphyseal (growth) plate in children -SH II is most common type (75%) w/ good prognosis -fracture involves physis and metaphysis -generally conservative management is appropriate -ORIF is often required for type III and IV
  49. 49. Salter-Harris Classification S – I – Slip A – II – Above L – III – Lower T – IV – Through R – V – Rammed
  50. 50. 44yo M w/ midfoot pain s/p MVA
  51. 51. Answer: Lisfranc Fracture
  52. 52. Lisfranc injury -6 bone tarsometatarsal complex = Lisfranc joint, separates midfoot from forefoot - 20 percent of injuries are missed in ED -Fx of base of 2nd MT is pathognomonic for disruption of Lisfranc ligamentous complex -look for loss of alignment of 2nd through 4th MT w/ associated tarsal bones; -MOA ranges from minor rotational force to high speed MVA -frequently require ORIF -May be complicated by DP damage and severe DJD
  53. 53. 70yo F s/p FOOSH

  55. 55. $200 Answer from H4 Your Text Here
  56. 56. Monteggia Fracture -ulnar shaft fracture w/ proximal radial head dislocation -easy to miss radial head dislocation so be sure to image the elbow -be sure to check posterior interosseous nerve (finger/wrist extension) fxn b/c it wraps around proximal radius; -requires ORIF - call ortho
  57. 57. 22yo M c/o pain at base of Lt thumb after punching wall
  58. 58. Answer: Bennet’s fracture
  59. 59. Bennet’s fracture -intraarticular fx at base of thumb -MOA: axial load to flexed/adducted thumb as in punch with closed fist -unstable fx - requires thumb spica and hand sx referral -complications include malunion, severe DJD

  65. 65. Maisonneuve Fracture -proximal fibular fracture assoc w/ rupture of deltoid ligament or fracture of medial malleolus (disruption of tibiofibular syndesmosis) -when you get ankle fracture, especially isolated medial malleolus fx, be sure to examine knee -requires immediate ortho consultation in ED -most require surgical repair of ankle fx/syndesmotic injury but may also be tx'ed conservatively w/ cast immobilization for 6-8 wks
  66. 66. 22yo F w/ foot pain s/p jump from 2 nd floor fire.
  67. 67. Answer: Calcaneus fracture
  68. 68. Calcaneus fracture -MOA:fall from height onto foot -if high degree of suspicion but no obvious cortical disruption, check Boehler angle: <20 suggests depressed fracture -emergent ortho consult - tx varies: orthopods usually use CT to determine plan but most non-displaced fx can be managed conservatively -high incidence of compartment syndrome w/ comminuted fractures -check lumbar spine -
  69. 69. 25yo M unrestrained driver w/ wrist pain s/p MVA
  70. 70. Answer: Barton’s fracture
  71. 71. Barton’s fracture -Fx of distal radial metaphysis w/ either volar or dorsal angulation (Colles/Smith) and intra-articular involvement and some carpal displacement – high force mech. -minimally displaced fx tx w/ splint and o/p ortho -unstable fx involving 50% of articular surface or associated carpal subluxation require ORIF - talk to ortho prior to d/c
  72. 72. 32yo M tree cutter, new onset quad s/p tree branch to head.
  73. 73. Answer: Jefferson fracture
  74. 74. Jefferson fracture -fracture of C1 resulting from significant axial load to top of the head -4 part fracture involving both anterior and posterior arches -associated SCI common -treatment depends on integrity of transverse ligament  intact ligament: tx w/ hard collar; disrupted ligament  halo or surgery
  75. 75. 55yo M unrestrained driver w/ wrist pain
  76. 76. Answer: Lunate dislocation
  77. 77. Lunate dislocation -similar to perilunate dislocation radiographically -triangular shape of lunate on AP view = &quot;piece of pie&quot; sign, lateral view shows lunate displaced volarly from radius = &quot;spilled teacup&quot; sign -unstable  emergent ortho consultation, most require OR -complications = early DJD, malunion/nonunion, AVN, median nerve compression
