Loss of Disc Height after Spontaneous Regression of a Herniated Lumbar Disc: A Case Report

ABSTRACT

STUDY DESIGN: Case report. 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. RESULTS: On MRI, spontaneous regression of the herniated lumbar discs was observed, but loss of disc height was also found. CONCLUSIONS: A herniated lumbar disc may be a risk factor for loss of disc height. It is important to recognize that a patient with a herniated lumbar disc can struggle with chronic lower back pain even if spontaneous regression of the herniated lumbar disc occurs.
