Q

What are the most common upper Cervical Spine fractures.

A

Odontoid fractures

MOI: Flexion loading is the cause in the majority of patients, and results in anterior displacement of the dens. Or, an extension loading force (forward fall onto forehead), which occurs in a minority of patients, and results in posterior displacement of the dens.

Q

Physical Exam: Use the motor and sensory exams to determine nerve root affected. A L5-S1 HNP causes S1 radiculopathy, which may reveal ankle plantar flexion weakness (foot drop) and decreased sensation at the bottom of the foot.

Q

This Injury is associated with what complication

A

Intra-capsular (Femoral neck): Usually associated with a high risk for non-union secondary to AVN.

Extra-capsular (intertrochanteric or above the lesser trochanter): requires a stronger fixation and has a better chance of healing.

Avulsion (Dancer's) fracture \*most distal, Zone 1
29
What Fracture
Jone's fracture, zone 2
30
What Fracture
Lisfranc fracture dislocation MOI: riding a horse and fell, Motorcycle, high mechanism injury Tender over 2nd metatarsal jointà if tender around there (RED FLAG)à get weight baring xray
31
What Fracture
Lisfranc fracture-dislocation
32
High ankle sprain aka
Syndesmosis ligament (Intraosseous membrane)
33
What Disease
Talus OCD (osteochondral defect) The floating piece is attached to scar tissue - can be painful with walking - go in scrap it out or keep an eye on in if it on the outside
34
What disease
Charcot's Foot Presentation: hot, red, infection, but no pain due to neuopathy
35
What Fracture
Maisonneuve Fracture
36
What Fracture
Pilon fx ## Footnote Unstable– straight force through the tibia and the bones explode VERY communited, very unstalbe Swelling a LOT In 24 hrsà need to wait for swelling to go down before surgeryà go into external fixaton
37
What Fracture
Massonneuve fx
38
What Fracture
Talus fracture

What Disease
Giant Cell tumor \*Most often occur after skeletal bone growth is completed and they account for 20 percent of benign bone tumors.
42
What Disease
Non-Ossifying Fibroma \*MC benign bone lesion in children \*Results from a defect of periosteal cortical bone development, which leads to failure of ossification. \*When the tumor occupies more than 50% of the diameter of bone, there is much greater risk for a pathological fracture.
43
Osteosarcoma usually develops where?
the knee or in other long bones, particularly in the bone metaphyses. \*can prevent an amputation by segmental arthroplasty
44
What Disease and tx?
Osteosarcoma \*Sunburst appearance TX: amputation or segmental resection
45
What Disease
Ewing's sarcoma \*Onion skin

51
What Disease
Fibrous Dysplasia \*It is characterized by expanding fibro-osseous tissue within affected bones and predominantly is a lesion of the growing skeleton.
52
What disease
Osgood Schlatter \*In children, these injuries are more common at the bone-tendon junction (adults: muscle-tendon)
53
\_\_\_\_ sign is when able to dislocate an unstable neonatal hip. \_\_\_ is to reduce an unstable neonatal hip. Limb-leg discrepancy: measure from the __ to \_\_, or request full extremity x-rays

What disease
Diskitis
56
What Disease
Spina Bifida
57
What disease
SCFE
58
What Disease and tx
Osgood Schlatter \*activity modification and ST immobilizaiton for 4-8 weeks
59

Pes Cavus deformity An abnormally high arched foot is usually secondary to an underlying neuromuscular disorder, until proven otherwise, with up to 60% found to be from a neurological etiology.
60
What disease and tx
clubfoot/talipes equinovarus ## Footnote Treatment: Sequential manipulation and casting and may require 2-4 months of treatment and splinting for up to another 5-7 years. Surgery when non-operative treatment failed and usually after 3-4 months of treatment. \*Physical exam: a true idiopathic clubfoot can not be corrected with passive manipulation
61
What disease
Child abuse \*Also look for avulsion-type or “corner chip” fractures
62
The most common complication after a physeal injury is
Premature partial arrest of growth (growth disturbance)
63
What type of Salter-Harris fracture
Type 2 Type II fracture is when there is a fracture across the physis which extends into the metaphysis
64
What type of salter harris fx
Type III fracture is when there is a fracture across the physis which extends into the epiphysis
65
What type of fracture
buckle/torus
66
What Fracture
Greenstick
67
Tx of femur fractures in peds
- Most fractures involve the femoral shaft and heal without incident in 6 to 12 weeks. - Closed treatment, such as traction or spica casting, was used more commonly in the past but is giving way to surgical fixation in children older than 6 years and adolescents to enable early mobility and improved outcome.
68
Non-displaced tibia and fibula fractures are treated with
a long leg cast for six to eight weeks. \*Repeat x-rays weekly to check fracture position.
