> 41
no joint problems
married
Treatment algorythm for AARD
1 week - head halter and analgesia
> 1 month - halo halter and analgesia
> 3 months or neuro - C1/2 fusion
Outcomes of surgical treatment of lumbar herniation pain without weakness
Improved pain and function at 4 years
What is the appropriate prednisone dosing for acute SCI
Only delivered if the patient arrived
Main tract affected by central cord syndrome
lateral corticospinal
Changes associated with an aging disc
decreased water decreased protein increased ratio keratin sulfate:chondroitin decreased nutrition increased enzymes
Risk of THA in ank spond
anterior hip dislocation
red snappers on a blue background
TB
Best position for occipitocervical 8mm unicortical screw
2 cm lateral to EOP
Smallest pedicle diamter
T6
primitive tissues
neural crest - peripheral
neural tube - spinal cord
notochord - anterior bodies and discs
which recurrent laryngeal nerve has a more variable course
right
50% will cross into the field (tracheoesophageal groove)
biggest predictor of symptoms in adult spinal deformity
saggital plane imbalance
characteristics of de novo spine deformity
smaller, shorter curve
fewer levels
more commonly in lumbar spine
most useful test to identify spinal stenosis in adult scoliosis
myelography
nonunion risk factors for T2 odontoid
fracture gap (> 1 mm) posterior displacement (> 5 mm) delayed start of treatment (> 4 days) posterior redisplacement (> 2 mm)
surgical indications for discitis
unsuccessful antibiotic treatment after 6 weeks
vertebral deformity or instability
neurological deficit
MRI showing >50% compression of thecal sac
depressed host immune response.
best method to assess progression of idiopathic curve by skeletal maturity
tanner-whitehouse III

what is the most common complication following cervical laminoplasty
C5 palsy resulting in biceps weakness
what is the most common complication following endoscopic transthoracic approach
intercostal neuralgia
where does the saggital plumb line fall
C7 to the posterior aspect of S1
what is true about revision micordiscectomy
equal outcomes to primary discectomy
electrical simulation for SCI patients has the most effect on which of the following
skeletal muscle
what has the highest negative predictive value of failure of nonoperative treatment with back pain
Visual analog scale
Factors associated with pseudoarthrosis in adult spinal deformity correction
> 55 anterior approach saggital balance > 5cm smoking kyphosis > 20 deg
what is the most powerful predictor of outcomes regarding lumbar stenosis
medical co-morbidities
when does the odontoid ossification center appear
appears at 3, fuses at 12yo
what percentage of patients with SCI suffer from depression
11%
what is the most sensitive test to diagnose # in ank spond
CT
when do you need to decompress cauda equina
48 hours
lower functional level following surgery for degenerative spondylolisthesis
smoking
risk of adjacent disease in lumbar spinal stenosis
adjacent level laminoplasty
