Lumbar Disc Degenerative disease: Magnetic Resonance Imaging Findings in Patients with Low Back Pain in Dar Es Salaam

Abstract

Background: Lower back pain (LBP) is a public health problem and lumbar disk degenerative disease (LDDD) is a main cause. Studies elsewhere show that the prevalence of LDDD ranges from 85% - 95%. MRI being the best modality for spine disorders, we studied pattern of LDDD in patients with LBP.

Methods: This was a seven months, hospital based descriptive, prospective study which involved all patients presenting with LBP referred for MRI. Patient characteristics were analyzed using SPSS version 13.

Results: One hundred and sixty five patients were recruited into the study. Their ages ranged from 20 to 80 years with a mean of 50±12.5 years. Female accounted for 87 (53%) of the cases.
Most of the patients had LDDD. The disease mostly affected individuals in the age group above 60 years (P<0.05) with no sex difference. Disk herniation, central canal stenosis and nerve root compression were significantly seen in patients with radiculopathy (P=0.00). L4/L5 & L5/S1 were the most affected.

Conclusions: LDDD occurs in all age groups but individual aged 60 years and above are most affected. There is a relationship between radiculopathy and disk herniation, central canal stenosis and nerve root compression. The lower lumbar spine levels remain the most affected area for disk degenerative disease.
