Bilateral L5 radiculopathy due to osteoporotic L1 vertebral fracture: A case report.
BACKGROUND
The true incidence of osteoporotic vertebral fractures is not well defined because many osteoporotic vertebral fractures are asymptomatic. Although the true incidence of neurological compromise as a result of osteoporotic vertebral fractures is not known, it is thought to be low. In this case report, we present a case of L1 osteoporotic vertebral fracture causing bilateral L5 nerve root compression and manifestation of bilateral foot-drop.


METHODS
Pedicle screws were inserted in the vertebrae, 2 above and 2 below the L1 vertebra. A temporary rod was placed on the left. An L1 right hemilaminectomy via a posterior approach and a corpectomy were performed. The spinal cord was decompressed. Anterior fusion was carried out by placing titanium mesh cage into the vertebrectomy site as a strut graft via posterior approach, and posterolateral fusion with spongious allografts were added to the procedure.


RESULTS
Two years later the patient was completely symptom free and receiving medical treatment for osteoporosis, which was diagnosed as primary type.


CONCLUSIONS
If a fracture is detected on the posterior wall of the vertebral body in computerized tomography (CT) examination with plain radiographs, a magnetic resonance imaging (MRI) examination should be conducted in the presence of symptoms and physical findings suggestive of neurological compression. Follow-up neurological examinations should be carried out, and it should be kept in mind that most of the neurological symptoms may develop late and manifest as radiculopathy. The majority of the osteoporotic vertebral fractures can be managed conservatively with bed rest and orthosis, but cases with accompanying neurological deficit should be managed surgically using decompression and stabilization by fusion and instrumentation.
