Q

What are the different types of imaging used (5 types) and what are they each used for?

A
  1. Radiograph – used mainly for simple bone and joint imaging
    • IMPORTANT: If joint is weight bearing order weight bearing x-rays

    • obtain perpendicular images
  2. CT – great for bone visualization
    • ALWAYS order CT before MRI
  3. MRI – great for soft tissue, spine, and joints
  4. Ultrasound – good for real time assessment of dynamic movement
  5. Bone Scans – not used, can see deformities of the bone

* NAT – non-accidental trauma * Clinical presentation * Fractured posterior rib * Fractured long bones (femur and humerus) before walking * Bruising, burns, scratches
112
Where does scoiliosis occur and what defines scoliosis?
* Scoliosis – severe curvature of thoracic and lumbar spine * Defined by curve size * Cobb angle must be greater than 10 degrees = draw perpendicular line from top bent vertebra and bottom bent vertebra and measure angle
113
What are the parameters for bracing scoliosis? What are the parameters for surgery on scoliosis?
* Parameters for bracing * 25-45 degree cobb angle * Still growing individual * Wear brace for 16-18 hours a day * Parameters for surgery * \>50 degree cobb angle
114
What is the general strategy for the work-up of orthopaedic infections?
* Infections involving joint or bone require prompt recognition and usually emergent irrigation and debridement to prevent long-term consequences * Routine work-up for any suspected infection: * Radiographs of affected region * Serum CBC, ESR, and CRP * +/- synovial fluid aspirate
115
What is septic arthritis and what treatment is generally used?
* Septic arthritis * Hematogenous spread to various joints * Treatment: surgical I&D and antibiotics
116
What are the common locations, organisms, and treatments involved in septic bursitis?
* Septic bursitis * Bursa are extra-articular synovial fluid-filled sacs that cushion tendons/muscles * Common locations: pre-patellar and olecranon bursa * Common organism: *S. aureus* * Treatment: antibiotics and operative excision
117
What is cellulitis, what are the symptoms, and what treatment is most often used?
* Cellulitis * Infection involving skin and subcutaneous tissue * Painful at rest and tender to palpation * Treatment: antibiotics
118
What is necrotizing fascitis and what is the general treatment?
* Necrotizing fasciitis * Infection involving fascia * Extremely aggressive infection that causes hemodynamic instability * Treatment: emergent and extensive debridement and IV antibiotics
119
What is osteomyelitis?
* Osteomyelitis * Infection of bone
120
What is lyme disease caused by, what is its appearance, and what is its treatment?
* Lyme disease * Caused by bacteria *Borrelia burgdorferi* * Characteristic “bull’s eye” rash * Treatment: doxycycline
121
What is aspiration in terms of joints?
* Aspiration = drawing of fluids in joint space
122
What diseases require aspiration and what diseases do not require aspiration? Think which ones swell and which ones do not swell.
* Acute atraumatic swelling differential * Effusion (intra-articular) requiring aspiration * Septic arthritis, gout, lyme disease, hemarthrosis, reactive arthritis, osteoarthritis * No effusion (extra-articular) requiring NO aspiration * Cellulitis, bursitis, and necrotizing fasciitis
123
What is flexor tenosynovitis? Where is it located and how is it diagnosed?
* Flexor tenosynovitis * At phalanges of hand * Kanavel’s Signs * Flexed posture, pain with extension, tender over flexor tendon, fusiform swelling (across joint space)
124
What is paronchia? What is it caused by? What is its treatment?
* Paronychia * Most common hand infection * Caused by *S. aureus* * At distal phalanx * Treatment: soaking
125
What is herpetic whitlow?
* Herpetic whitlow * Painful vesicles filled with clear fluid and erythema
126
What is a felon and what is it caused by?
* Felon * Abscess of distal finger pulp * Caused by *S. aureus*

* Sporothrix schenckii * Subcutaneous fungal infection * Caused by penetrating injury while handling rose thorn
129
How is septic arthritis in children treated? Why is this condition more common in children?
* Septic arthritis * Requires I&D * More common in kids because bones are more vascularized
130
