Q

Flexor Tendon Avulsion Fracture MOI

A

Traumatic forced extension of actively flexed finger leads to an avulsion of flexor tendon at base of distal phalanx
Other mechanisms include spontaneous tendon rupture seen in patients with RA

Q

Distal Phalanx Fracture surgical management

A

if the fracture is open, angulated more than 15 degrees and displaced more than 2 mm, if conservative management fails or if theres is non- union surgery is needed

Q

Extensor Tendon Avulsion Fracture non surgical management

Study These Flashcards
A

Continuous splinting for 6-8 weeks

but if extension is lost at any point, healing is disrupted and the clock starts again

24
Q

Extensor Tendon Avulsion Fracture surgical management

Study These Flashcards
A

if there is failure to heal with conservative care, or if the tendon is completely lacerated or is the the fracture involves more than 30% of the articular surface

25
Mallet fracture treatment
drill .035 k wire through distal phalanx into the middle phalanx and the avulsed fracture is reduced, loop by be needed the finger is then splinted fir 6 weeks and then k wire is removed
26
Distal Radial Fracture MOI colle's Fx
FOOSH w/ wrist in EXTENSION this is most common
27
Distal Radial Fracture MOI smith's Fx
FOOSH w/ wrist in FLEXION
28
common fracture for postmenopausal women
Colle's Fracture
29
Colle's Fx clinical presentation
dinner fork deformity localized swelling potential for median nerve injury Significant ROM limitation
30
Smith's Fx clinical presentation
garden spade deformity localized swelling potential for median nerve injury Significant ROM limitation
31
which Xray should you get for a colle's fracture
AP and lateral and oblique view
32
which Xray should you get for a smith's fracture
AP and lateral and oblique view
33
Colle’s Fracture Reduction
closed manipulation, wrist dorsiflexed
34
Distal Radial Fracture non surgical management
if it is not displaces give a short arm case | if it is displaces give a long arm cast to maintain reduction
35
Distal Radial Fracture surgical management
used when there is a Neurovascular injury, the fracture is open, there is and Intra-articular extension, theres is Severe comminution or if there is an Inability to maintain reduction
36
Pediatric Distal Radial Fracture
a pediatric distal radial fracture it is most common in children under 10 Distal metaphysis Buckling of cortex due to compression failure
37
Radial Torus “Buckle” Fracture MOI
FOOSH
38
Radial Torus “Buckle” Fractureclinical presentation
mild to moderate swelling, guarded limited ROM, no visible deformity
39
Radial Torus “Buckle” Fracture management
short arm was for 4 to 6 weeks
40
radial Greenstick fracture
a pediatric distal radial fracture less common than buckle Complete fracture of the TENSION side of the cortex with buckling of the compression side
41
radial Greenstick fracture MOI
FOOSH
42
radial Greenstick fracture clinical presentation
mild to moderate swelling, guarded limited ROM, a visible deformity may be present
43
radial Greenstick fracture management
Short arm cast for 6-8 weeks | Rarely require surgical management unless significant angulation, neurovascular injury, or Open Fx
44
Scaphoid Fracture
the most common fractured carpal bone MOI is FOOSH Clinical findings Snuffbox pain / TTP ROM limitations Common for Fx to be occult on initial x-ray
45
Scaphoid Fracture limited blood supply
high incidence of nonunion and osteonecrosis
46
greenstick on x ray
complete disruption on one side with buckle on opposite side
47
when is 5th Metacarpal “Boxer’s” Fracture non surgical Management used
less than 15 degrees of angulation | Transverse, oblique, base & head Fx
48
when to get a surgical consult for a 5th Metacarpal “Boxer’s” Fracture
Open fracture, > 15 degrees angulation, Intra-articular, Comminuted fx, Spiral fx
49
5th Metacarpal “Boxer’s” Fracture
MC fracture of the hand Distal metaphysis of 5th metacarpal MOI is Closed fist striking an object
50
5th Metacarpal “Boxer’s” Fracture clinical presentation
Localized swelling +/- malrotation deformity +/- dropped knuckle deformity
51
malrotation
pinkie over ring finger
52
Scaphoid Fracture – Management
Long-arm thumb spica cast for 6-12 weeks If clinical exam is indicative of fracture but x-rays are negative, splint and repeat x-rays in 10-14 days If follow up x-rays still negative but clinical concern persists order MRI
53
Displaced transverse and oblique fractures tend to
angulate
54
Spiral fractures tend to
rotate
55
for Fractures of the Metacarpals and Phalanges, Ortho referral for surgical evaluation when?
Displaced (> 2mm), spiral, comminuted and intra-articular fractures Uncorrected angulation and malrotation
