Thoracic and lumbar spinal stenosis in a patient with Klippel-Feil syndrome
Case report, 107 - 110Tag this article
Klippel-Feil syndrome (KFS) represents a congenital condition, which is characterized by improper segmentation or congenital fusion of at least two cervical vertebrae. It is responsible for a variety of skeletal and extraskeletal manifestations, including spinal stenosis presenting almost universally in the cervical region. We present a rare case of a 55-year-old man, who was never diagnosed of KFS, and developed symptomatic lumbar and thoracic spinal stenosis. The patient were offered surgical treatment. More precisely, he underwent open hemilaminectomies and laminectomies at L1-L4 and T6-T9 levels, respectively. Instrumentation was not applied, since the spinal column’s rigidity and stability were not compromised. Clinical improvement was immediate and remarkable. The first day after surgery the patient was already pain free. At the last follow-up, 24 months later, the patient remained ambulatory, with no residual pain, and without evidence of spinal instability or sagittal malalignment.
