Introduction

Given the rising incidence of obesity in the adult population, it is more than likely that orthopaedic surgeons will be treating more obese patients with lumbar disc pathologies. The relationship between obesity and recurrent herniated nucleus pulposus (HNP) following microdiscectomy remains unclear.

Objectives

To investigate the relationship between obesity and recurrent HNP following lumbar microdiscectomy.

Study design: A prospective comparison of MRI findings with surgical findings in patients presenting to our spinal triage service with a prospective diagnosis of a lumbar disc herniation.

Objective: To investigate consistency between radiologists interpretation of MRI scans, and comparison between MRI and surgical findings, in an attempt to identify those patients suitable for percutaneous treatment.

Background: MRI has assumed a preeminent position in the diagnosis of lumbar disc prolapse.

Methods: 87 consecutive patients presenting with signs and symptoms suggestive of a lumbar disc prolapse that underwent an MRI and based on that a discectomy.

Results: Reliability tests show only fair agreement (k=0.36) between the radiologists and at best only moderate agreement (k=0.41) between the radiologists and surgical findings.

Conclusions: MRI is an excellent tool for diagnosis of a disc prolapse but does not appear to help in classifying discs suitable for percutaneous treatment.
