Abstract
Objectives
We report 3 cases of loss of disc height after spontaneous regression of a herniated lumbar disc.
Summary of Literature Review
Reports of spontaneous regression of a herniated lumbar disc were identified.
Materials and Methods
We conservatively treated 3 patients who were diagnosed with a herniated lumbar disc. During outpatient follow-up, radiating pain improved in all patients, but they complained of chronic lower back pain. Magnetic resonance imaging (MRI) was performed for diagnostic purposes.
