Radiculopathy in Degenerative Lumbar Scoliosis: Correlation of Stenosis with Relief from Selective Nerve Root Steroid Injections

Objective.  The purpose is to define the origin of radiculopathy of patients with degenerative lumbar scoliosis‐stenosis and to assess the correlation between percentage of initial radicular leg pain relief with selective nerve root injections and lateral canal dimensions. Design.  Retrospective cli...

Description
Summary:Objective.  The purpose is to define the origin of radiculopathy of patients with degenerative lumbar scoliosis‐stenosis and to assess the correlation between percentage of initial radicular leg pain relief with selective nerve root injections and lateral canal dimensions. Design.  Retrospective clinical study. Setting and Patients.  Thirty‐six consecutive patients (average age 72) from Twin Cities Spine Center with degenerative lumbar scoliosis (average major curve 25°) and radicular symptoms were studied. Interventions.  Patients underwent 46 selective steroid injections of nerve roots concordant with clinical symptomatology. Outcome Measures.  Radiographic measurements included major and lumbosacral curve Cobb angle. Computerized measurements of magnetic resonance imaging (MRI) included minimum subarticular height and foramen cross‐sectional area of the nerve roots that were injected. Initial response from the nerve root injections was also rated. Results.  Twenty‐five percent of nerve root symptoms were coming from the major curve, 72.2% from the lumbosacral hemicurve and 2.8% from both (P
