Q

What are the 4 causes of fractures?

A

-Traumatic # = caused by abnormal trauma e.g. fall, sport, car accident
-Pathological # =fracture in bone weakened by disease
-Periprosthetic # = fracture at point of mechanical weakness of an
implant
-Avulsion # = tendon or ligament remains intact but pulls off bone fragment

  5. b. type: if articular, is it complete (no part of joint attached to metaphysis)? Yes (type c), go to 7
  6. Group: if extraarticular (A) what is the fracture pattern?Avulsion (1), simple (2), wedge or multifragmentary (3)
  7. Group: if partical articular (b) what is the fracture pattern? Simple (1), split and/or depression (2), fragmentary (3)
  8. Group:lf complete articular (c) what is the articular pattern? simple (1), multifragmentary (2)
  9. Subgroup: if complete articular (c) what is the metaphyseal fracture pattern? simple articular with simple metaphyseal (1)
    simple articular fracture with multifragmentary
    metaphyseal (2),

Q

What js an extra articular, type A fracture?

A

The fracture line may be metaphyseal or epiphyseal, but it always spares the articular surface although it may be intra capsular.

Q

What is a partial articular, type b fracture?

A

The fracture involves part of the articular surface while the remainder of the joint remains intact and is solidly connected to the supporting metaphysis and diaphysis.

Q

What is a complete articular, type c fracture

A

There is a disruption of the articular surface and the articular surface is completely separated from the diaphysis.

19
Q

What are the additional classifications of fractures?

A

Relationship to the environment
- Open vs closed

Extent
- Complete vs incomplete

20
Q

What are open fracture classifications (OTA-OFC)?

A
21
Q

Name this pathological fracture

A

Myeloma: a malignant tumor of the bone marrow

22
Q

Name this pathological fracture

A

Fibroma: typically a benign fibroid or fibroid tumor; composed of fibrous or connective tissue.

23
Q

What is this special fracture?

A

FOOSH Scaphoid fracture

  • Most common type of carpal bone fracture
  • Pain at base of thumb-ASB tenderness
  • Men 20-30 yrs, adolescents/young adults
  • Needs specific scaphoid view
  • 10% distal, 70%-80% Waist, 20% proximal pole
24
Q

Name this special fracture

A

Colles Fracture = distal radius

  • Transverse 1+ partially fragmentation of distal radius
  • Distal component dorsally displaced and angulated
  • Associated transverse fracture of Una styloid
  • Also called a “dinner fork” or “bayonet” due to shape of forearm
  • Often from FOOSH
  • Common in osteoporotic bones, middle age → elderly
25
Q

Name this special fracture?

A

. dislocation of the radial head/proximal radio ulnar joint) with of the ulna

26
Q

Name these special fracture?

A
27
Q

Name this special fracture?

A

Weber A ankle fracture

  • Fracture of the lateral malleolus distal to the syndesmosis
  • Below level of ankle joint/mortise
  • tib/fib syndesmosis intact
  • Deltoid ligament intact
  • Medial malicious often fractured
  • Usually stable but can require ORIF
28
Q

Name this special fracture

A

Weber B ankle fracture
• Fracture at the level of the syndesmosis
- At level of ankle joint, extending superiorly and laterally up fibula
- Tib/fib syndesmosis intact or only partially torn
- Deltoid ligament may be torn
- Medial malleolus often fractured
- Variable stability

29
Q

What is this special fracture

A

Weber C ankle fracture

  • Fracture proximal to the syndesmosis
  • Above level of ankle joint
  • Tib/fib syndesmosis disrupted
  • Deltoid ligament injury or medial malleolus fracture present
  • Unstable -requires ORIF
30

31
Q

  • # diaphysis fifth metatarsal
32
Q

Name this special fracture

A

Patella fracture

  • Hard blow to front of knee
  • Surgical vs conservative management
33
Q

What are the 3 hip classifications?

A
  • subcapital/ intracapsular fracture
  • intertrochanter/ extracapsular fracture
  • subtrochanteric fracture
34
Q

What are the 4 intracapsular fractures

A
  • Type I fractures have the best outcome. The bone ends are impacted into one another, which facilitates vascular re-growth.
  • Type II fractures are not impacted and are thus less stable. However there is minimal displacement of the bones from the anatomically normal position, and this is beneficial.
  • Type III fractures are complete but there is only partial displacement (50%).
  • type IV fractures are complete with total displacement (50%). The two ends of bone are completely separated.
35
Q

    of the following:

    or/and
  • Bony tenderness over posterior edge of medial malleolus /distal 6cm)
    or/and
  • Inability to weight bear /immediately and in ED)
36
Q

What are the OTTAWA ankle/foot rules?

A
  • A foot x-ray series is required if there is pain in the mid foot zone and any of the following
  • Bony tenderness over base of 5th metatarsal
    or/and
  • Bony tenderness over the navicular
    or/ and
  • Inability to weight bear /immediately and in ED)
37

  • Isolated point tenderness of patella
38
Q

How do you describe a dislocation?

A 
• Where has it occurred?
• How has it typically moved?
- anterior/posterior
- medial/ lateral
- superior/inferior
39
Q

Why are fractures missed?

A
  • Poor history and examination
  • Not linking radiology with clinical findings
  • Failure to examine all views
  • Poor methodical approach
  • Failure to order special views (1 view is 1 view too few)
  • Failure to identity need for a comparison view
  • Failure to get a second opinion
40
Q

What are indications for for hip X-rays?

A
  • trauma
  • hip pain
  • abnormal gait
  • inability to weight bear
  • arthropathy

  • Lateral
  • Horizontal beam lateral
  • Clements-Nakayama
  • Dunn view
42
Q

What does a pelvis X-Ray examine

A

Examines the main pelvis ring, obturator foramina, sacroiliac joints, symphysis pubis, acetabulum, sacral foramina and proximal femur.

43
Q

What are indications for a pelvic X-Ray?
