History of CA and radiculopathy, how does XR influence your mgmt?
|
If evidence of mets, almost 100% chance cord compression, but even if not evidence of mets still 25% chance of cord compression. Should have low threshold for MRI.
|
|
What are risk factors for vertebral mets
|
older patient, known CA, unexplained wt loss, pain at rest or worse at night
|
|
What are the spinal emergencies?
|
Cauda equina, vertebral mets, epidural abscess, fracture
|
|
What is most sensitive finding in cauda equina syndrome besides back pain?
|
Urinary retention - sometimes present with overflow incontinence; If PVR>100 cc, suspect this Dx.
|
|
What are 4 signs of cauda equina?
|
Hyporeflexia, urinary retention, decreased rectal tone, saddle anesthesia
|
|
Causes of cauda equina syndrome
|
central disk herniation, hematoma (trauma, esp if on coumadin), malignancy, epidural abscess, surgery)
|
|
What are risk factors for Epidural abscess and what Percentage of Epidural abscess patients have no risk factors?
|
IVDA, alcohol use, immunocompromised, DM, dental work
|
|
What is classic triad for EDA and what percentage of patients have all 3?
|
Fever, back pain, neuro deficits, but only see all 3 in 15% of patients
|
|
What is sensitivity of ESR for detecting EDA?
|
if cutoff is 30, sens = 81%
if cutoff is 20, sense = 98% Problem is that in the at risk population, ESR is often high (HIV, EtOHics, IVDAs) |
