Title: Pediatric back pain<br/>Author: Brian Corwell<br/><a href='http://umem.org/profiles/faculty/294/'>[Click to email author]</a><hr/><p>
Children are prone to inflammation and infection of the intervertebral discs</p>
<p>
-Mean age 3-5years at presentation.</p>
<p>
</p>
<p>
Lumbar region frequently involved</p>
<p>
</p>
<p>
Although disc biopsy is not necessary for diagnosis, as many as 60% of biopsied discs grow bacteria</p>
<p>
-Usually Staphylococcus aureus.</p>
<p>
</p>
<p>
Untreated - may spontaneously resolve or progress to vertebral osteomyelitis or abscess</p>
<p>
</p>
<p>
Chief complaint: Back pain and irritability, often associated with a limp or refusal to crawl or walk.</p>
<p>
<strong>Fever is absent or low grade. </strong></p>
<p>
Physical examination findings are nonspecific and may include a tendency to lie still and percussion tenderness over the involved spine.</p>
<p>
Blood culture is generally sterile,</p>
<p>
WBC count can be normal early in the disease course</p>
<p>
</p>
<p>
<strong>However, the ESR is elevated in >90% of patients. </strong></p>
<p>
</p>
<p>
Plain radiographs are normal at the start of the illness, and generally take 2-3 weeks to demonstrate narrowing of the intervertebral space.</p>
<p>
</p>
<p>
Therefore imaging study of choice is MRI.</p>
