25 Questions

1. Orthopedic (Tibial / Forearm Fx) - Vascular (Ischemic-reperfusion injury - hemorrhage) - Iatrogenic (Vascular puncture in anticoagulated patients - IV/intra-arterial drug injection - constrictive casts) - Soft Tissue Injury (Prolonged limb compressio

2. Irrigation & antibiotics in ED - I&D in OR

3. Conscious sedation - Hip flexed - knee hyperextended - ______ moved back in place - Immediate pain - long term relief from capsular injury

4. Hx of recent fall or MVC - Prolonged steroid use - Hx cancer - CKD - Metabolic disorders -> Pathalogic Fx - Pain @ site of injury - Pain @ knee - groin - other injured sites

5. Infection secondary to poor I&D - Compartment syndrome disabilities - Fx not adequately aligned

6. Forceful contraction of ____ - Falling on flexed knee - Patients over 40 years

7. Most common fracture of foot - MOA: stubbing mechanism - crush injury - Dx: Xrays - Tx: Buddy taping - hard soled shoes

8. Valgus deformity w/ flexion - Laxity >1cm w/o endpoint: complete rupture - Laxity <1cm w/ endpont: incomplete/partial tear - no laxity but pain: ligament strain

9. Varus deformity w/ flexion - Laxity >1cm w/o endpoint: complete rupture - Laxity <1cm w/ endpont: incomplete/partial tear - no laxity but pain: ligament strain

10. Early detection w/ high index of suspicion - Initially complain of severe pain - poorly controlled w/ analgesics - Pain starts few hours after injury - Swollen - firm - tender to squeeze by examiner

11. Recurrent lateral dislocation (15% of cases) - Superior - horizontal - intercondylar disolcations - Irreducible dislocations

12. Radiographs required if pain in malleolar zone plus:- Tenderness at base of 5th metatarsal - posterior medial / lateral malleolus - navicular - can NOT take 4 steps immediately and in ED

13. Shortening / rotation of lower extremities - Lacerations - bruising - tenderness - crepitence @ site - Instability of extremities - Limited ROM - Pain w/ motion - Significant pain w/ weight bearing - even if Xrays show no fx (Suspect for femoral neck

14. Widening of Pubic Symphysis - Disruption of SI Joint - Sacral ligament injuries

15. Most common mechanism of pelvic fracture (50%) - occurs when pedestrians are broad-sided by car

16. Presentation: fibula may be fx at head -> 6 cm above ankle joint - Tx: Reduce / stabalize fractured medial malleolus - secure fibula to distal tibia

17. MOA: vertical or mediolateral forces exerted on base 5th metatarsal while heal is raised and foot plantar flexed - Or significant adduction force applied to forefoot - while ankle is plantarflexed - Sudden change in direction w/ heel off ground in sp

18. Intra-Articular: immobilization w/ well padded posterior splint - strict elevation - non-weightbearing - analgesia - ortho f/you - Extra-Articular: Immobilization - analgesia - ortho f/you

19. Knee in 30 degrees flexion - Stabalize femur above knee - anterior force applied behind tibia @ tubercle level -> attempt to displace tibia anteriorly - >5mm movement = ligament tear

20. The _______ of the upper extremity is most likely to develop compartment syndrome - Tibia (Anterior - Posterior - Medial)

21. Ortho referral - NSAIDs and partial weightbearing - Difinintive Dx by MRI & arthroscopy

22. I&D - splint -> Xrays - Tetanus shot - parenteral Atbx - Cefazolin for open Fx - Measure pressures if Compartment suspected

23. Most common tarsal bone fx - 2 categories: Intra-Articular Fx - Extra-Articular Fx - Associated injuries are common

24. Vertical displacement of bones @ SI joint and mid-pubic rami - SI ligament may occur

25. May be ambulatory - focal patellar tenderness - swelling - effusion - potential for poplitieal artery injury - check distal pulses
